forced transcode to

[goerdi]

Hi !

Is it possible to set jellyfin up to try first the transcode to AV1 ?

The client reports to the server what it can support. If the client supports AV1, and you have AV1 encoding enabled on the server, it should prefer transcoding to AV1.

In my testing it always transcodes to AV1 on clients that support decoding it. Even if the only reason for the transcode is to burn-in subtitles.

To build on what Dread said, to enable AV1 transcoding on the server, navigate to Dashboard -> Playback -> Transcoding and check the box for "Allow encoding in AV1 format." Keep in mind that if your server doesn’t support AV1, you may encounter playback issues.

Also on the WebUI, click on your profile picture in the top-right corner of the homepage, then go to Playback. From there, you can choose your preferred video codec for transcoding.

When media is transcoded, it generates an FFmpeg log (Dashboard -> Logs). In the FFmpeg log, look for the stream mapping section, which will indicate the format it's being converted to.

Code:

Stream mapping:
  Stream #0:0 -> #0:0 (hevc (native) -> av1 (av1_qsv))
  Stream #0:1 -> #0:1 (eac3 (native) -> aac (libfdk_aac))
