SteamLink - Linux Arm64

This SteamLink wrapper automatically checks for a SteamLink binary and, if one is found, it checks a version.txt file and compares the contents to the latest available. If there is no version.txt file or there is a new version, SteamLink is downloaded automatically with wget.

Don't have wget or curl? Go here: http://cdn.origin.steamstatic.com/steamlink/rpi/bookworm/arm64/public_build.txt and use the URL from that file to download the latest SteamLink binary. Extract the bin/shell file to steamlink/bin.

Disclaimers

This distribution is intended for Rocknix/Batocera for the Retroid Pocket 5 and Retroid Pocket Mini.

Thanks

A million thanks to Noxwell for their work on this, where the previous version of this wrapper was not functioning.

https://github.com/JeodC/Steamlink-Arm64

I used the ultra requirement for now but in theory any device on mainline (i.e. has x11) should work...I think. SteamLink uses about 833MB of ram.

welp, I’ll have to try this tomorrow

gentle anchor Mar 3, 2025, 1:16 AM

Oh it needs a wrapper library for different GPUs I think. To intercept the open and ioctl calls so they go to our actual DRM device instead of DMA_HEAP

It might just need a library edit.

If it has opengl it has x11.

austere sigil Mar 3, 2025, 1:21 AM

"To intercept the open and ioctl calls so they go to our actual DRM device instead of DMA_HEAP"
How would it give it the calls to a drm device if it doesnt exist

RP has it as

#define DMA_HEAP_PATH "/dev/dma_heap/vidbuf_cached"
#define DRM_DEVICE_PATH "/dev/dri/renderD128"

So for your x55 the paths are wrong

is the DMA_HEAP_PATH Important?

gentle anchor Mar 3, 2025, 1:52 AM

Yeah we're intercepting the video stream where it wants to display at its own specific paths and substituting our own.

#

this is getting interesting

subtle hazel Mar 3, 2025, 2:13 AM

#

I'm guessing it's the ioctl call in the wrapper being incorrectly targeted for whatever GPU is in your device, as Jeod hinted to earlier. Fill me in on what device you're using and, if you happen to know, what GPU driver you use for it? Currently the wrapper only targets MSM for Qualcomm GPUs

austere sigil Mar 3, 2025, 2:14 AM

#

I mean the x55 it uses Panfrost on a Mali-G52

#

if that helps

gentle anchor Mar 3, 2025, 2:15 AM

#

It's the x55

#

If you know a good method for gathering the info you need, we have tons of devices across our community

austere sigil Mar 3, 2025, 2:16 AM

#

but it also supports libmali so it could be a mess

gentle anchor Mar 3, 2025, 2:17 AM

x55 has so many hardware revisions it's probably the worst test candidate.

austere sigil Mar 3, 2025, 2:18 AM

gentle anchor x55 has so many hardware revisions it's probably *the* worst test candidate.

subtle hazel Mar 3, 2025, 3:10 AM

#

If you're feeling adventurous and use weston as your compositor, you can try removing or commenting out the line
export SDL_VIDEO_DRIVER="x11" in the launch script to try using wayland directly

#

I know for a fact it doesn't work with sway right now though

#

If you see "No support for YU12 mod 0" it's not something that can be helped at the moment

#

Or if there's just no video lol

#

Or if you don't have either weston or x11(which can actually be xWayland but don't tell steamlink that) you can try to set SDL_VIDEO_DRIVER="kmsdrm" which should theroretically give better performance according to some code comments I've found.

No desktop GL needed as far as I've seen. h264 decoding is software based atm so it should be okay? And yes, I recall seeing something like GLIBC_3...6? I know there was a 3 and a 6.

One thing I noticed with Sway on libmali rocknix is that it will open a X11 display and listen on that socket, but Xwayland will immediately crash when an app opens a connection because it links to libGL.so, which is missing. Weird misconfiguration.

austere sigil Mar 3, 2025, 3:56 AM

#

they should really get libGL.so fixed

untold scarab Mar 3, 2025, 3:57 AM

#

Well they can't really. That's the desktop GL part that you don't have on libmali.

subtle hazel Mar 3, 2025, 4:08 AM

#

So from the supported devices list on the portmaster websie, It seems like I'll need to have support for libmali, panfrost, and msm since that covers what looks like all of those devices? Any oddball gpus I'm missing off the top of the head?

@pearl heath This is the one that hates get_controls if that’s a must-have for some reason.

Nope

pearl heath Mar 3, 2025, 4:11 AM

Neat 😄

subtle hazel Mar 3, 2025, 4:17 AM

#

Hmm. libmali might be off the table since it doesn't seem to have a standard DRM_IOCTL call for GEM handles. panfrost and msm for now then.

subtle hazel Mar 3, 2025, 5:04 AM

#

Here's the combined msm/panfrost GPU support library compiled for aarch64 for those who want to replace it themselves. Source available at https://github.com/beebono/SLink-RPCompat/blob/main/gpucompat.c
I'm going to bed for now though!

Hm, not for me.

subtle hazel Mar 3, 2025, 12:20 PM

#

Might be because I remapped the controller when trying to fix the sticks earlier. I'll try clearing that

#

Cleared out storage/.lccal/share/Valve* but it's still happening for me... maybe I'm just cursed but it's most noticeable when tring to use the Big Picture menu to exit the stream rather than the overlay/

#

Commenting the GPTOKEYB line fixes it, so it's like it's reading both inputs?

#

OH

gentle anchor Mar 3, 2025, 12:37 PM

#

I was considering not using gptokeyb to force a graceful exit anyway.

subtle hazel Mar 3, 2025, 12:38 PM

I forgot to put the empty binding file in

gentle anchor Mar 3, 2025, 12:38 PM

LOL

subtle hazel Mar 3, 2025, 12:38 PM

So yes, it was reading both inputs lol

subtle hazel Mar 3, 2025, 12:57 PM

#

Also here's the armhf version of the steamlink shell executable with RPi library dependencies haphazardly patchelf'd out and an armhf libgpucompat if anyone wants to try it? I couldn't get it to work on my RPMini becuase of an illegal instruction in shell, but if you have an ARMv7 thing you can try!

📎 libgpucompat-armhf.so 📎 shell-armhf

gentle anchor Mar 3, 2025, 12:59 PM

#

That still needs the armhf libs we provide from the lib folder though.

#

    libavcodec.so.59
    libavutil.so.57
    libdouble-conversion.so.3
    libicudata.so.72
    libicui18n.so.72
    libicuuc.so.72
    libmd4c.so.0
    libSDL3.so.0
    libSDL3_image.so.0
    libSDL3_mixer.so.0
    libSDL3_ttf.so.0

#

These all need armhf versions if you want to use the armhf shell

subtle hazel Mar 3, 2025, 1:00 PM

#

The ones it needs are in the zip from the Valve cdn. I can pop that in here if you want

gentle anchor Mar 3, 2025, 1:02 PM

#

Oh let me do some sorting then

subtle hazel Mar 3, 2025, 1:03 PM

#

These shouuuld be the ones we need

📎 shell-armhf-libs.zip

#

The rest were provided via /usr/lib32 on rocknix, so hopefully?

#

No guarantees the patchelf'd version will work though. It might actually call something in the RPi libs

#

If it does I can pull those in too, but for now let's try without.

#

Oh, probably also need the Qt5.14.1 folder.

TrimUI is a perfect device for steamlink if we can get westonpack working with it.

Let's see...catching up. Westonpack needs xwayland?

#

So I don't remember if I mentioned it and I'm too lazy to search the thread right now, but I think shell does support using KMS/DRM directly for non compositor environments as long as it can grab the master role using SDL_VIDEO_DRIVER="kmsdrm"

#

I guess I could try by killing the sway service on the RPMini out of curiosity

gentle anchor Mar 3, 2025, 4:36 PM

#

I'm 99% sure I tried that export and while the steamlink app booted up it would'nt grab the stream

subtle hazel Mar 3, 2025, 4:43 PM

#

Ah right, and even with QT_QPA_PLATFORM="eglfs" and QT_QPA_EGLFS_INTEGRATION="eglfs_kms" it still doesnt work right?

gentle anchor Mar 3, 2025, 4:44 PM

#

Nope

subtle hazel Mar 3, 2025, 4:45 PM

#

Darn, okay. Guess we have to stick with a compositor

gentle anchor Mar 3, 2025, 4:51 PM

#

Unfortunately I don't remember what I did to get it to boot into the initial gui on muos. I remember getting it to do that on rg40xxh.

subtle hazel Mar 3, 2025, 4:54 PM

#

Oh it needs libmtdev

#

for eglfs/kmsdrm

#

It starts rotated on t RPMini though so you need QT_QPA_EGLFS_ROTATION="something" too

#

90, -90, or 270

#

NOt sure which

gentle anchor Mar 3, 2025, 4:57 PM

#

libmtdev?

subtle hazel Mar 3, 2025, 4:59 PM

#

aarch64 version, remove the .0.0 for it to work

📎 libmtdev.so.1.0.0

#

or symlink it, up to you

gentle anchor Mar 3, 2025, 4:59 PM

#

I got it already but I still can't load it

#

Is the shell wrong?

📎 Steamlink.sh

subtle hazel Mar 3, 2025, 5:02 PM

#

I don't think so? Here's the direct cmdline I'm running so it should be able to pick it up without the preload...
QT_QPA_PLATFORM="eglfs" QT_QPA_EGLFS_INTEGRATION="eglfs_kms" QT_QPA_EGLFS_ROTATION="-90" SDL_VIDEO_DRIVER="kmsdrm" LD_PRELOAD="/roms/ports/steamlink/lib/libgpucompat.so" LD_LIBRARY_PATH="/roms/ports/steamlink/Qt-5.14.1/lib:/roms/ports/steamlink/lib:/usr/lib/compat" /roms/ports/steamlink/bin/shell

#

But uh, if you rotate eglfs, the actual stream is rotated then

gentle anchor Mar 3, 2025, 5:03 PM

#

I'm testing it with trimui and knulli, not rocknix

subtle hazel Mar 3, 2025, 5:03 PM

But the menu isn't

#

OH

#

Pop ldd in the launch script real quick to see if it's missing any libs?

gentle anchor Mar 3, 2025, 5:04 PM

#

Yeah it wants all these wayland libs

subtle hazel Mar 3, 2025, 5:04 PM

#

...whyyyy though

#

It shouldn't even be TOUCHING wayland

#

You killed weston/sway right?

gentle anchor Mar 3, 2025, 5:08 PM

I don't have weston on trimui/knulli

subtle hazel Mar 3, 2025, 5:08 PM

gentle anchor Mar 3, 2025, 5:08 PM

subtle hazel Mar 3, 2025, 5:08 PM

gentle anchor Mar 3, 2025, 5:08 PM

#

Like I said I was somehow able to get the app itself to boot on fbdev in muos two months ago but streaming would crash.

subtle hazel Mar 3, 2025, 5:09 PM

#

You could try QT_QPA_PLATFORM="linuxfb" instead?

gentle anchor Mar 3, 2025, 5:09 PM

#

Tried it

#

There's https://discord.com/channels/1122861252088172575/1291537436286914580 where they have it working on knulli, I'll look for some hints

subtle hazel Mar 3, 2025, 5:12 PM

#

I know your on the TrimUi, but

hell``` works (rotated) on RPMini

#

Huh, linuxfb DOES want libwayland-*... why?

#

Oh I think it's just baked into shell's dependencies?

#

Swapping the QT_QPA and doing ldd still shows libwayland- no matter what

gentle anchor Mar 3, 2025, 5:16 PM

#

Yeah but I don't trust my WSL setup to not pull a bunch of unnecessary subdependencies.

subtle hazel Mar 3, 2025, 5:18 PM

#

I think I have them already in my WSL, let me see...

gentle anchor Mar 3, 2025, 5:18 PM

#

I'll just borrow them from my Mini

subtle hazel Mar 3, 2025, 5:18 PM

#

Probably the better idea

gentle anchor Mar 3, 2025, 5:20 PM

#

Now it wants libgssapi_krb5.so.2 but rocknix doesn't have that

subtle hazel Mar 3, 2025, 5:20 PM

#

I mean... we could patchelf --remove-needed shell every time it updates :p

#

That's in /usr/lib/compat I think

#

libgssapi_krb5.so.2 => /usr/lib/compat/libgssapi_krb5.so.2

#

same with krb5support, k5crypto, and keyutils

#

No

#

qt.qpa.plugin: Could not load the Qt platform plugin "linuxfb" in "" even though it was found.

subtle hazel Mar 3, 2025, 5:26 PM

#

HMMM

#

libevdev.so.2? I feel like that should be distro provided

#

The only major differences I see between xcb and linuxfb are:
xcb: (all the x11 stuff), libICE.so.6, libSM.so.s6
linuxfb: libdrm.so.2, libevdev.so.2, libinput.so.10, libmtdev.so.1

#

and libudev.so.1 for linuxfb

Weird suggestion, but maybe try without export QT_PLUGIN_PATH="$GAMEDIR/Qt-${QT_VERSION}/plugins"?

gentle anchor Mar 3, 2025, 7:22 PM

#

No dice unfortunately

subtle hazel Mar 3, 2025, 7:23 PM

#

QT_QPA_PLATFORM linuxfb doesn't support opengl "This plugin does not support createPlatformOpenGLContext!" but SDL is probabyl trying to initialize it for the overlay surface

#

So might need to try QT_QPA_PLATFORM="eglfs" with QT_QPA_EGLFS_INTEGRATION="eglfs_kms" again unfortunately

#

...unless you were able to get into the stream with the SP?

gentle anchor Mar 3, 2025, 7:25 PM

No stream

The binaries are available at
https://github.com/PortsMaster/PortMaster-New/blob/main/runtimes/weston_pkg_0.2.aarch64.squashfs

Most of westonpack is open source software like Weston or Xwayland with some specific hacks applied to support some weird stuff (like headless mode while still capturing input devices).

Crusty is my compatibility layer that basically reroutes GLX and EGL (X11, Wayland and GBM extensions) into an SDL2 window, optionally through GL4ES. It also (poorly) emulates a DRM device just enough for most apps to believe they're interacting with a real one.

If you're looking for source code, sorry, I'm sadly not ready to publish it yet. It's a hot mess while I debug. Some devices are still in flux. The source will be released under MIT soon though.

Ah thank you both! I'll take a look through and see if it's even what I'm hoping for. I'm really just needing to get past the /dev/dri/card0 init in SDL because I feel like the rest can be handled by fake memfd "DRM" buffers

#

All Steam Link really wants is somewhere to store the pixel data before trying to blit it to the EGL surface

#

But SDL insists it needs a DRM device for that

untold scarab Mar 4, 2025, 3:43 AM

#

subtle hazel Ah thank you both! I'll take a look through and see if it's even what I'm hoping...

Have you traced what it's trying to do? If it just needs any file to be present so that open returns a FD. You can try mknod or a LD_PRELOAD hack.
I already went to bed let me see if I can at least share that code. That should be relatively stable.

subtle hazel Mar 4, 2025, 3:44 AM

#

I've tried mknod but it errno 6's me

#

Haven't done a full strace or anything yet

#

We're already using LD_PRELOAD for the DMA_HEAP -> DRM device buffer allocation which works for the X55 and RP5/Mini

#

So i'll probably add to that

#

Will just do a check somewhere "if the drm device doesn't respond right, do a memfd buffer instead"

Warning: Hot mess.

So this assumes you have created a fifo file at /tmp/drmpipe. It hooks into open() to redirect any request for /dev/dri/card0 to /tmp/drmpipe. It also answers a couple of DRM related ioctl requests. There's also two functions that are used by my libdrm stub to do some signalling acros process boundries.

Really? I'm hooking every open. For me it works quite well. It can't be more than like 1000 total calls until all the files are loaded, right?

subtle hazel Mar 4, 2025, 4:04 AM

#

It would if sway didn't like to open recursively to find stuff 🙃

#

I had to add path[0] == '/' to the first if and somehow that helps A LOT

#

But with WAYLAND_DEBUG=1, I saw sway do: open"dev", open"dev/dri", open"dev/dri/whatever", open"dev/yada/yada..." a LOT

#

Which seems REALLY inefficient to me but maybe I don't understand it

Hum. So something about my libgpucompat.so wrapper seems to be what's messing with the controls.

Because when I don't LD_PRELOAD it, controls work

Also I'm treating myself to late birthday gift with a TrimUI Smart Pro, so that might be my next target

gentle anchor Mar 5, 2025, 2:55 PM

#

Neat! I think we don't need the shell libs if we aren't using kmsdrm...

subtle hazel Mar 5, 2025, 2:55 PM

#

Oh, probably yes

#

I would move the krb5 related ones into the main libs.aarch64 though

#

Unless you would rather keep the /usr/libs/compat in the launch script instead

#

Because I removed that because we had them in the folder already. whoops

gentle anchor Mar 5, 2025, 2:57 PM

#

It's alright

subtle hazel Mar 5, 2025, 2:58 PM

#

It might just improve compatibility to keep them in the long run though

#

Valve could always add new dependencies anyway

gentle anchor Mar 5, 2025, 2:59 PM

#

Nah I'll move krb5 to mainlib and keep shell folder for later if we end up getting ksmdrm to work

#

Will just skip shipping the unused libs for PM package

subtle hazel Mar 5, 2025, 2:59 PM

#

Sounds good

gentle anchor Mar 5, 2025, 3:00 PM

#

Next I'll see if I can wrap the download script into our PM patcher gui..

subtle hazel Mar 5, 2025, 3:01 PM

#

That would decrease launch friction a bit yeah.

#

Wouldn't need to sit there with a black screen for a bit

#

Also it would keep it from breaking if new dependcies are added

gentle anchor Mar 5, 2025, 4:14 PM

Ok, got it more user-friendly. Try wiping it entirely from your folder and start from scratch 🙂

subtle hazel Mar 5, 2025, 4:16 PM

subtle hazel Mar 5, 2025, 4:24 PM

#

Pretty!

#

Do we need to chmod +x on download?

#

Or will PortMaster handle that?

#

Oh, I guess I also need the libs that aren't pulled from the tar, whoops!

#

Yeah, other than me forgetting the chmod and libs, it works! Got into the stream and launched Big Picture, inputs worked.

gentle anchor Mar 5, 2025, 4:34 PM

We do need to chmod +x shell

#

Now I need to figure out a way to use the mouse...

With the stick

subtle hazel Mar 5, 2025, 4:36 PM

#

Do you want it in Stream or just in general? In steam, open the overlay by holding select and there's a mouse mode

gentle anchor Mar 5, 2025, 4:37 PM

No I got that but it's the software cursor ingame that seems broken

So what's the recommended firmware for PortMaster on the TrimUI Smart Pro? Stock, CrossMix, or Knulli? I feel like Knulli will be the easiest to test on

subtle hazel Mar 6, 2025, 4:24 AM

#

Maybe using something other than relying on the distro's tar would be best since I seem to be getting "tar: stdout: write error" on Knulli when trying to patch via the launch script. Weird part is that it extracts the shell part just fine, the rest errors out.

gentle anchor Mar 6, 2025, 4:27 AM

#

subtle hazel Maybe using something other than relying on the distro's tar would be best since...

Knulli has strict permissions

subtle hazel Mar 6, 2025, 4:28 AM

#

Ah, try stock then?

gentle anchor Mar 6, 2025, 4:28 AM

#

Eh

#

You just need to Chmod the tar

#

Throw that in the download script, chmod 777 right after it downloads

subtle hazel Mar 6, 2025, 4:29 AM

#

I'll pop that in the download script for now then yeah

#

Oh, upon actually looking at the files, it IS extracting them

#

They all just have NO permissions

#

except shell

#

so I'm going to do the stupid and add chmod -R 777 ./* to the launch script before the actual run

subtle hazel Mar 8, 2025, 9:42 AM

In the latest edition of "What? Why is that like that???", it turns out that Steam Link checks for Linear pixel format modifiers but NOT wildcard pixel format modifiers. So it insists that wayland doesn't support YU12 Linear, when really it supports YU12 "anything"

Hi there, I'm trying to run steamlink on EmuElec, but it doesn't start, the log.txt says:
./bin/shell.aarch64: error while loading shared libraries: libwayland-client.so.0: cannot open shared object file: No such file or directory
Any ideas? I know that EmuElec doesn't have x11, - and I'm not sure if xwayland is installed, too - is that the reason? Can I check that somehow?

subtle hazel Mar 11, 2025, 1:56 PM

tiny elm Hi there, I'm trying to run steamlink on EmuElec, but it doesn't start, the log....

What device are you trying to use it on? Some of them have incompatible gpus at the moment.

tiny elm Mar 11, 2025, 1:59 PM

#

It's an amlogic s905x2

#

I know that you don't support Emuelec, but I just wanted to try if it works... so no problem if you say that's not your issue!

fierce blaze Mar 11, 2025, 2:02 PM

#

Yes, as the title says, you need xwayland

#

Btw have you had any success with westonpack under emuelec? I have no clue if it works there

tiny elm Mar 11, 2025, 2:05 PM

#

Yes, I got Superhexagon running, and this uses westonpack, right? That's why I thought that perhaps SteamLink will work, too...

subtle hazel Mar 11, 2025, 2:05 PM

#

Also I’m not sure if even with xwayland that that GPU would be detected right at the moment.

#

And I have yet to implement westonpack heh

#

Been busy with updating the Half-Life port whoops

Well that explains it ;D

tiny elm Mar 11, 2025, 2:06 PM

Let me take a look at what was shipped after I take my dog out for the morning.

tiny elm Mar 11, 2025, 2:08 PM

Thank you, and as I said, it's completely up to you if you want to cope with that. But you would definitely make a lot of us EmuElec users really happy... so I will just stay tuned and check again. Thanks for your feedback!

📎 SteamLink.zip

#

So Steam Link has like three render modes.

QT_QPA_PLATFORM=xcb SDL_VIDEO_DRIVER=wayland
QT_QPA_PLATFORM=linuxfb SDL_VIDEO_DRIVER=kmsdrm```

#

xcb is the default, so that can be omitted if you want

#

And I commented out my preload near the top, if you want to try using it feel free

#

I really do think we can get away without my preload IF we can get it to ignore dma_heap somehow

Because currently Steam Link is hardcoded to use dmabufs from /dev/dma_heap

Sweet, trying it in a moment

Line 86, Column 90

#

Also Because it can't extract the first symlink in order, it bails completely

So uh. maybe *.so.5.14.1 then rename? A bit clunky but it should work

Although I guess we want to make sure we can do it no matter what version they move to.

gentle anchor Mar 12, 2025, 12:24 AM

I’ll see what else I can do. Maybe there’s a flag to ignore symlinks.

subtle hazel Mar 12, 2025, 12:26 AM

#

Apparently there is!

#

‘-h’

    When reading or writing a file to be archived, tar accesses the file that a symbolic link points to, rather than the symlink itself. See section Symbolic Links. ```

Got rid of the perrmission errors real quick. Still complains about symlinks but it at least extracts the files we need and the rename fixes that up too

#

OH BOY I GOT THE RARE ERROR

#

WTF
ffmpeg error: get_buffer() failed
ffmpeg error: decode_slice_header error
dmabuf_alloc failed
WTF
ffmpeg error: get_buffer() failed
ffmpeg error: decode_slice_header error
dmabuf_alloc failed
WTF```

#

They're just like us frfr

#

So this makes me think that it's actually MY implementation that is badwrong

untold scarab Mar 12, 2025, 2:12 AM

#

ugh, i wish i could rewrite like 10 lines of code on the steam link app, then this would already be over.

YUP

#

Closed source baybeeee

#

Well, closedish source

untold scarab Mar 12, 2025, 2:13 AM

#

yeah looking at the decomp it's so obvious they just extended that example code you linked me

subtle hazel Mar 12, 2025, 2:13 AM

#

I mean... that person works at valve so

#

Or at least works WITH valve

untold scarab Mar 12, 2025, 2:14 AM

#

ohhhh that makes more sense

subtle hazel Mar 12, 2025, 2:14 AM

#

I emailed them actually, very nice

#

Though they couldn't tell me anything other than "Keep checking the source files, sorry"

#

Better safe than sorry

#

Oh you know what would be better than wayland UI and x11 rendering?

#

x11 UI and wayland rendering

#

You know what I'm gonna try

untold scarab Mar 12, 2025, 2:22 AM

#

It's not gonna work on westonpack. EGL Wayland support is minimal, just enough to make weston happy enough to boot.

subtle hazel Mar 12, 2025, 2:23 AM

#

Oh, well...

#

Let me dream

#

And I don't think their wayland implementation uses egl?

#

It's just x11 as far as I can tell

#

Or at least, it has separated egl and wayland things

untold scarab Mar 12, 2025, 2:25 AM

#

On wayland you have no choice but to use EGL. Even if you don't, all the 0 copy buffer sharing that wayland does in the background, absolutely relies on EGL

subtle hazel Mar 12, 2025, 2:25 AM

#

Oh I see

Who knew tar implementations were so weird

subtle hazel ```dmabuf_alloc failed WTF ffmpeg error: get_buffer() failed ffmpeg error: decod...

WTF

#

I love programmers

#

So...no go for westonpack? Bummer.

subtle hazel Mar 12, 2025, 12:10 PM

#

Maybe. It's still up in the air I think. I'm not sure we actually need to do a custom "eglCreateImageKHR" because I found that the Steam Link source already does that part

#

I'm going to keep plugging away at it for a bit longer

gentle anchor Mar 12, 2025, 12:12 PM

#

Having a buddy at Valve kinda helps motivation I guess.

subtle hazel Mar 12, 2025, 12:12 PM

#

Buddy is a strong word

#

More like they responded to one email

gentle anchor Mar 12, 2025, 12:13 PM

#

Oh I thought you were acquaintances

#

Are you telling me you just outright emailed customer support? :v

subtle hazel Mar 12, 2025, 12:13 PM

#

No, I'm not that silly

#

I emailed the SDL guy directly

#

I expected NO response

gentle anchor Mar 12, 2025, 12:14 PM

#

The SDL guy

#

Icculus?
