Tunarr Version: 0.18.14
Docker via Unraid

I'm having an issue where some channels are refusing to load on Tunarr and on Plex. I eventually get an error in Plex with the message "Unable to Evaluate Play Request" I've attached a log and noticed it has multiple errors in it but I don't know what to make of it.

📎 tunarr.log

the errors in the Tunarr logs are unrelated - those errors are 404s for trying to find thumbnails from Plex

Even this line?

#

ah, i didn't see that one.

#

just a sec

safe nymph Mar 18, 2025, 2:00 PM

#

yeah that error shows up any time I try playing the problem channel. Whats weird is I'm using the same transcode profile for all of my channels and this is the only one not working.

alpine marten Mar 18, 2025, 2:00 PM

#

not sure why that would create the Plex error you are seeing but that's definitely a problem in any case

#

it looks like it is related to being an on-demand channel

safe nymph Mar 18, 2025, 2:00 PM

#

I don't have that option toggled. I don't have any on-demand channels

alpine marten Mar 18, 2025, 2:01 PM

#

weird. the error you posted is definitely about on-demand channels and pausing them

#

it might just be erroring when checking whether it needs to pause it

#

so still probably not the root cause

safe nymph Mar 18, 2025, 2:02 PM

#

hmm, thats strange.

#

okay, I just changed the stream mode from MPEG-TS back to HLS and now the channel is loading in Tunarrs UI

#

and it just loaded on my phone after changing to HLS.

#

I'm coming from Ersatztv and figured since MPEG-TS worked in that environment it would work the same in Tunarr but I guess not

alpine marten Mar 18, 2025, 2:04 PM

#

Tunarr works very similar to ETV, but the naming is slightly different

#

HLS in Tunarr is like "HLS Segmenter" in ETV

#

both also expose a "wrapper" MPEGTS stream on top of that for use in clients that want a continuous MPEGTS stream (e.g. like an HDHR)

#

so HLS provides the most flexibility in that the channel can stream in both clients that support proper HLS streaming and those that want MPEGTS - and both will use the same underlying stream session within Tunarr

safe nymph Mar 18, 2025, 2:08 PM

#

would this also provide more stabilty between media types? Because the channel we were just looking at has old media (720p 4:3 aspect) and somewhat newer media (1080p 16:9)

#

I've noticed with ETV at least it really had issues swapping between resolutions.

alpine marten Mar 18, 2025, 2:10 PM

#

IMO the experimental pipeline + HLS stream mode is the most robust combo in Tunarr right now. that said there's an outstanding bug for more gracefully handling channels that have mixed aspect ratios (namely exposing "scaling behavior" as an option + implementing a scale+crop option to go with it)

#

what scaling behavior do you use in ETV?

safe nymph Mar 18, 2025, 2:11 PM

#

Scale and Pad, its the default setting so I didn't tinker with it.

#

anything dealing with FFmpeg is a mystery to me.

alpine marten Mar 18, 2025, 2:12 PM

#

haha yea, it gets complicated very quickly

safe nymph Mar 18, 2025, 2:13 PM

#

I will say though, swapping back and forth between tunarr and ETV, your Plex integration with adding media to channels is second to none. It couldn't be easier. The main reason I swapped from ETV was it would randomly stop seeing my Plex collections so adding media wasn't as streamlined.

alpine marten Mar 18, 2025, 2:16 PM

#

thanks! there are def pros and cons to the approaches taken by each system. Tunarr hits the Plex API every time you load those pages so it's always getting up-to-date info. ofc the downside is that Tunarr doesn't always have a "full view" of what's available. i'm trying to work on something that is sorta the best of both worlds. i appreciate the feedback there though, it's important for me to know what's working in addition to what's not so i dont go breaking the good UX

safe nymph Mar 18, 2025, 2:18 PM

#

I'm very impressed so far with it.

#

hmm, so strangely enough, the channel started working but when it needed to transition to the next media, I get the same error as before and its unable to load in Tunarr again.

alpine marten Mar 18, 2025, 2:32 PM

#

safe nymph Even this line? 2025-03-18T08:43:39.867Z [error]: Error while trying to pause c...

you get this error you mean?

#

if so that is indicating the stream is dying for some other reason

#

while that's definitely an error in tunarr, that code executes after a stream has ended

#

(checking whether the channel is on-demand and whether it needs to be paused)

#

so i think that is probably a symptom and not a cause

safe nymph Mar 18, 2025, 2:34 PM

#

I'm getting a good bit of 404 errors from Plex. Could it be some issue with API between Tunarr and plex?

#

this is my latest logs

#

📎 message.txt

alpine marten Mar 18, 2025, 2:38 PM

#

if they are all /api/metadata/external requests than i dont think it's indicative of a real issue, just a lot of missing thumbnails

safe nymph Mar 18, 2025, 2:39 PM

#

whats weird is I have that metadata in Plex, I'm not sure why it would have issues getting it

alpine marten Mar 18, 2025, 2:39 PM

#

that looks like an actual ffmpeg error

safe nymph Mar 18, 2025, 2:40 PM

#

could this be related to the experimental pipeline?

alpine marten Mar 18, 2025, 2:41 PM

#

certainly possible, though at this point "experimental" is kinda a misnomer.... we'd need ffmpeg logs to see why the stream crashed

safe nymph Mar 18, 2025, 2:41 PM

#

uno momento

#

This is the tail end of whats in my docker containers logs. I can get the error again and have it send more logs if this doesn't give you the full picture

📎 message.txt

alpine marten Mar 18, 2025, 2:44 PM

#

you'll need to enable the extra ffmpeg logs if you havent already

#

under settings > ffmpeg

safe nymph Mar 18, 2025, 2:44 PM

#

I have it set to debug

alpine marten Mar 18, 2025, 2:44 PM

#

console or file?

safe nymph Mar 18, 2025, 2:44 PM

#

Console, but I can change to file and attach it here

alpine marten Mar 18, 2025, 2:45 PM

#

interesting, there should be a buttload of logs in that case

#

ffmpeg debug level is extremely noisy

#

if you are pulling from the tunarr log file itself, they wont be there

safe nymph Mar 18, 2025, 2:45 PM

#

well this is just a snippet of the end of what my Unraid console window will show me. I can get a file for you

alpine marten Mar 18, 2025, 2:45 PM

#

the ffmpeg logs get piped only to the stderr stream of the process

#

yea a file might be more useful so that the ffmpeg logs arent interleaved w/ the tunarr ones

#

fwiw this was actually something i was going to work on fixing today. getting ffmpeg logs in tunarr is kinda cumbersome

safe nymph Mar 18, 2025, 2:48 PM

#

this is the error log and the transcode log

alpine marten Mar 18, 2025, 2:49 PM

#

perfect

#

this is a bug

#

[Parsed_overlay_cuda_5 @ 0x14e69c0298c0] Failed to configure output pad on Parsed_overlay_cuda_5```

#

thanks for finding this!

#

i'll see if i can get a repro and fix this up shortly

#

having logs like this helps me squash these issues fairly quickly

#

so this looks like a 10-bit hevc 1080p file, is that right?

safe nymph Mar 18, 2025, 2:52 PM

#

its definitely 1080p HEVC. I'm guessing its 10 bit since its saying input format: p010le

#

I'm messing with Tdarr right now to see if I can convert any 10-bit to 8-bit.

alpine marten Mar 18, 2025, 2:53 PM

#

no worries, tunarr should definitely support this case. there is clearly a missing normalization step here

safe nymph Mar 18, 2025, 3:00 PM

#

I wonder if I can filter out 10 bit until this gets resolved.

safe nymph Mar 18, 2025, 3:51 PM

#

Do you think changing the transcode option to HEVC would resolve this issue for the time being? Right now I have it set to H264.

alpine marten Mar 18, 2025, 4:18 PM

#

i dont think so - it's a problem with inputs and not outputs

#

but you could try

#

i'd be curious if it changes anything, but i think it's just a limitation of overlay_cuda not wanting 10-bit inputs (tunarr has to convert them down before doing the hw overlay)

safe nymph Mar 18, 2025, 5:01 PM

#

yeah testing HEVC transcoding didn't do anything for it.

alpine marten Mar 19, 2025, 4:44 PM

#

have a prospective fix here

#

this was a really specific situation - basically a 10-bit input that was already at the target resolution, so it needed no scaling, plus a watermark overlay happening all on hardware. just had to detect the situation and add the appropriate conversion down to 8-bit before doing the overlay

#

in the future, a (possibly) better improvement would be to force software overlay, then we'd be able to skip the 10->8 bit conversion on the source... but that ofc comes with it's own cons

safe nymph Mar 19, 2025, 5:40 PM

#

I'm assuming because it would be software transcoding it would be more CPU intensive?

alpine marten Mar 19, 2025, 5:42 PM

#

yea, it would apply the watermark on the CPU, then re-upload frames back to the GPU for hw encoding

#

so you wouldn't get the hit of encoding the final output on the CPU, but it would be running some of filters on the CPU

#

incurs the cost of moving frames between CPU and GPU as well

safe nymph Mar 19, 2025, 5:46 PM

#

I wonder if you could implement this as a toggle in settings.

#

It would be pretty hard to describe but then you'd let the user decide which trade off they want to make

#

also, unrelated to this issue, is there a dev branch tag I can apply to get the newest features?

alpine marten Mar 24, 2025, 3:27 PM

#

and yes, you can use "edge" - it is built and pushed every 2 hours

#

yea i have an open bug for some "advanced" transcoding settings, such as forcing software watermarks and such
