VOD and Series are being software transcoded about jellyfin.xtream

[Kevinjil]

Did some random samples, and I could not reproduce it. The transcoding itself is all handled by Jellyfin, so you might have to open an issue upstream. GPU is used on my end when the codecs are available.

@Kevinjil Thank you for the answer. I'll check further and see what could be causing the problem. I'll close the issue if you cannot reproduce it.... I'm using Jellyfin 10.8.10 in a Docker container. What is the version you are targeting?

[wolfallein]

@Kevinjil I tried to play the same video locally (video downloaded and placed on the movies library) and remotely (using the plugin VOD).

When I played locally, Jellyfin correctly decoded and encoded using hardware, but when playing VOD Jellyfin used software decoding and decoding. I noticed that the command used to call ffmpeg are different in the logs. Here is for the video played locally:

Jellyfin is not adding a few arguments to make the hardware acceleration work properly in VOD. I tried to change the server version to 10.8.4 and saw no difference. For testing, I added the movie link to the m3u file I use for LiveTV in Jellyfin, and the hardware acceleration worked well for encoding (not decoding). Here is part of the log:

So I wonder if some flags need to be set to enable hardware acceleration with VAAPI. I tried a Jellyfin server on a Windows machine with AMD AMF, and the plugin worked well with hardware transcoding.
Since it works on local files and even in LiveTV, I'm unsure if I can report issue upstream... I wonder if you have any idea of where I could try to look.

Ok,

I found a way to fix this problem in my case. I added some content of MediaStreams in MediaSourceInfo() in the file:

https://github.com/Kevinjil/Jellyfin.Xtream/blob/v0.6.1/Jellyfin.Xtream/Service/StreamService.cs#L359

So, now the function MediaSourceInfo returns:

            return new MediaSourceInfo()
            {
                EncoderProtocol = MediaProtocol.Http,
                Id = id.ToString(CultureInfo.InvariantCulture),
                IsInfiniteStream = isLive,
                IsRemote = true,
                Path = uri,
                Protocol = MediaProtocol.Http,
                MediaStreams = new MediaStream[]
                {
                    new MediaStream
                    {
                        Type = MediaStreamType.Video,
                        // Set the index to -1 because we don't know the exact index of the video stream within the container
                        Index = -1,
                        IsInterlaced = true
                    },
                    new MediaStream
                    {
                        Type = MediaStreamType.Audio,
                        // Set the index to -1 because we don't know the exact index of the audio stream within the container
                        Index = -1
                    }
                },
                RequiresClosing = restream,
                RequiresOpening = restream,
                SupportsDirectPlay = true,
                SupportsDirectStream = true,
                SupportsProbing = true,
            };

It seems that if MediaStreams is empty, it doesn't get populated when ffprobe is called, and when jellyfin calls ffmpeg, it doesn't give all the stream details.
To give a better context, I'm running Jellyfin in a Docker container on a Linux machine. Jellyfin version is 10.8.10, and I'm using the integrated intel GPU with QuickSync driver.

Got inspiration from the file:
https://github.com/jellyfin/jellyfin/blob/e5dcaa6ed52a22360958e5d2054f55924f2a1512/Emby.Server.Implementations/LiveTv/LiveTvManager.cs#L315

[wolfallein]

That actually didn't fix all the problems. It probably messed with all the media information, and I ended up getting hardware acceleration in some scenarios.
I tried a new installation of Jellyfin 10.8.4 with plugin release 0.6.1.0 on a Windows machine, and I can reproduce the lack of hardware acceleration as it happens on my Linux server.
Jellyfin stores information about the media in many different places. I found information about the stream in:

metadata/channels/...
cache/channels/...
and likely in the Jellyfin database

When ffprobe checks the stream, it stores the information about the media in the database, from what I could see, and not in the files in metadata/channels/../../channelmediasourceinfos.json or cache/channels/../../*.json which are created when the lists are updated.

When Jellyfin tries to play the stream, the file in metadata/channels/../../channelmediasourceinfos.json seems to get priority and the information gathered by ffprobe is not used. So the result is that ffmpeg does not know relevant information from the stream to enable hardware transcoding.

I did some tests after removing metadata/channels/../../channelmediasourceinfos.json files, and it properly transcoded using hardware acceleration because jellyfin likely used the information from ffprobe stored in the database.
It would solve the problem by removing the *.json files, but every time the channels are updated the *.json files get restored, so it would be good to avoid the creation of them or make ffprobe stores the information on them, but I could not find where in the plugin source to fix this. The source responsible for the creation of the files is this one:

https://github.com/jellyfin/jellyfin/blob/v10.8.10/Emby.Server.Implementations/Channels/ChannelManager.cs#L354

So, @Kevinjil, to replicate this problem, you probably need a clean installation. If you have time to check this, let me know if you can reproduce the problems and if something on the plugin side can be done to fix this. If nothing can be done on the plugin side, I'll try to open this issue upstream.

Thank you for all the work

[Kevinjil]

I will check when I have some time, thanks for the input.

I'm interested on this issue too...
