#FFmpeg not writing stream file

I am trying to get a basic configuration set up with ErsatzTV and I cannot get it to stream any media. I get errors on multiple media files (.mkv anime with EN/JP subs and audio), both with hardware transcoding on and with it off.

I am running this in a virtual machine (Proxmox with hardware passthrough) running Ubuntu 22.04 LTS, with ErsatzTV using the latest version via Docker (jasongdove/ersatztv:latest-vaapi). I also attempted this outside of Docker with identical results. Host (outside of Proxmox) is a Dell OptiPlex 7050 Micro with an Intel(R) Core(TM) i7-6700T CPU @ 2.80GHz (Intel HD Graphics 530). I do not have a discrete GPU.

The same hardware can stream these video files fine in Jellyfin, so I do not reason to believe that the files are corrupted.

FFmpeg report is attached. The last few lines (below) also repeat infinitely, which was trimmed.

[vist#0:0/av1 @ 0x5604c6190e40] Error submitting packet to decoder: Invalid data found when processing input
[av1 @ 0x5604c619ee40] Missing Sequence Header.

Software used to view stream is VLC (testing) and Jellyfin (end goal).

Any help would be appreciated!

Tracked down issue. It's something with -c:v av1. Removing this encodes the files just fine.

#

Is there an "advanced" way to customize ffmpeg args to remove this without me having to hack together an ffmpeg middleware to remove this arg?

no, you don't need to customize anything, there's a bug with the av1 decoder selection, it should be using libdav1d - working on a fix now

#

to be clear, the problem is decoding, -c:v av1 before the input is the decoder. etv doesn't support encoding to av1

I'll take a look. Thank you!
