Need help to configure transcoding

[Indra]

Hi All,

I'm nubie on jellyfin so please don't hate me asking stupid question..

1. All my sourve video was stored in AV1, 4K format
2. Users are view the video via web browser, since this a dynamic user, we can't install apk on everyone come and go.
3. Some device unable to play AV1 properly, (it support AV1, but in software decoding, so it will stutter a lot) 
4. Is there a way to force HEVC transcoding? I can't do limiting bitrate or bandwith, since AV1 have the lowest bitrate, if I lower the bandwith below that to force encoding to h264/5, the result is hideous.
5. Is there a way to limit resolution to 1440p, the option available only 1080p and 4K, i try to edit encoder.xml with <MaxStreamingResolutionHeight>1440</MaxStreamingResolutionHeight> but it doesn't work.
6. Force transcoding on DLNA is working, but we can't skip or fastforward the video, is there any configuration needed to allow it?

thanks

What type of videos are you trying to playback? most movies and tv shows are not AV1, If it is something from a video site like YouTube there are ways to configure the downloading tools to avoid AV1.

You should try to avoid AV1 files if you can help it, it takes alot of cpu power to playback unless your device has a hardware decoder for AV1 which alot of stuff doesn't.

You can use HandBrake to convert the files to h265 or whatever codec you want to use. That way they will directly playback and it will look better than trying to transcode your videos on the fly in realtime.

As for setting your transcoding options. open Jellyfin in your browser and click the three lines in the top left corner, dashboard, playback, transcoding and you can change alot of the options here. its too much to really go into here but there is a help link at the top to read more about it.

So for transcoding to h264 is easiest h265 is harder and AV1 is hardest still, it will do h264 by default.

For the max resolution there is an option for screen resolution, did you try that? I don't know what resolution your monitors are at but I assume not 4k. I haven't personally used that option but it should work.
