Live TV Transcode - williamthrilliam - 2024-02-12

Hello,

My live TV is transcoding when it shouldn't be. I'm using a HDHomeRun FLEX 4K and it works fine direct playing in other apps. I also have the setting to force direct play on live TV but it's not being respected. I did see this on github, but I'm running 10.8 and should be running with that fix.

RE: Live TV Transcode - tmsrxzar - 2024-02-12

that's the ffmpeg log, not specifically useful other than confirming it was transcoding

the jellyfin server log is what's needed, it will contain a line TranscodeReason to say "why" it was transcoding

RE: Live TV Transcode - TheDreadPirate - 2024-02-12

What setting are you talking about for "forcing" direct play? There is a setting to force transcoding. Some clients (Android TV) have settings to force direct play. But I don't recall seeing a "force direct play" on the server side.

FWIW, a lot of newer client devices are starting to drop hardware accelerated decoding for mpeg2.

RE: Live TV Transcode - williamthrilliam - 2024-02-24

Hi thanks all, didn't seem get notified of replies.


There is a direct stream live tv (transcoding is disabled) option under preferences > playback > live tv. This is for the jellyfin android app version 0.16.5. Here are the correct logs:

RE: Live TV Transcode - TheDreadPirate - 2024-02-24

Strange that the video would get transcoded when only the audio was detected as needing to be transcoded. The TS container supports mpeg2 so there is no technical reason it would need to. I'm going to say that is a bug and you should submit a github ticket to the server git.
