SOLVED: Intel Transcoding Crashes

[valthonis_surion]

How many liveTV channels do you have?  Is this a HDHomeRun or some IPTV service?

Maybe 40ish channels if you count all the dot subchannels and it is HDHomeRun providing the input.  All channels are in the upper 80% or mid 90% for signal quality too.

"[ERR] FFmpeg exited with code 139"

if ffmpeg exited does the ffmpeg log show why

Pretty sure that is the message in their first post.

Code:

[h264_qsv @ 000001cb4bb2cf40] Error during encoding: device failed (-17)
Error submitting video frame to the encoder

I haven't been able to find anything online regarding this message other than problems with the source.  I double checked that RaptorLake supports mpeg2 decoding (that is the video stream video codec).

By default, transcoding for QSV doesn't enable hardware MPEG2 decoding, its not checked, so I assume its doing that via CPU.

indeed, in the first post *when the system was still running windows 11

are we still getting the same error now that the system has been wiped and had linux installed was more my question

if yes, the system is just possessed or the TV streams provider (be it a hdhomerun device or iptv) is just broken

I assumed the same thing, but as mentioned if I add an Nvidia GPU and use Nvidia transcoding, no issues.

In Dashboard > Playback, is MPEG2 checked?  The log indicates it is CPU decoding (mpeg2video (native)).  It SHOULDN'T matter, but I wonder what happens when you switch it to hardware decoding.  Intel's docs indicate that RaptorLake still supports decoding MPEG2.

Good catch, it shouldn't matter but so far after enabling that its been stable for the last 30 minutes or so.  Letting it continue to play, but usually within 30 seconds or so would stall.  So massive win so far.
Also makes sense why the Nvidia card would work, Nvidia transcoding defaults to MPEG2 hardware decoding in Jellyfin where as QSV does not.

As mentioned I will let it continue playing for a while, but looking really good!   


---EDIT for solution
Had to enable "MPEG2" hardware decoding under the "Playback" section for Intel QuickSync transcoding.
This fixed the issues with transcoding HDHomeRun OTA broadcasts
