No video only blackscreen with audio playing

[TheCaging]

Describe the bug

Been using jellyfin for awhile but recently its become entirely unusable. Couple days ago I uploaded a few movies to my server and went to my AndroidTV to see if they were scanned in. Then I tried playing one and all I get is a black screen with only the Audio. I know the files are good as they playback fine through the browser on my computer and android app on my phone but on my AndroidTV it gives the above behavior. This behavior extends to all video content through the AndroidTV app even stuff that worked before the bug appeared. I've tried rebooting multiple times, I've deleted the app and reinstalled, I've even deleted the server and started from scratch and it still does the same thing. I know In the log file there are issues with the trickplay but I was having this issue even with the trickplay disabled.

Can you post your video details that you find under media info on Jellyfin web or ffprobe?

I now got one film with the same issue. Audio plays fine but there's no video. Only a black screen. The video plays fine inside a browser and the iPhone client. I haven't tried the Android client but the Android TV client only shows a black screen while the audio plays and the film advances normally.

What looks different to me is that when you click on Media Info the video track is not the first track at the top.

On an Android tablet, the video plays when Web Player is selected but a black screen is displayed when set to Integrated Player. The audio plays in both cases.

Does this issue appear to be related? https://github.com/jellyfin/jellyfin-androidtv/issues/3830

Were these files modified with FFMPEG 6 or mkvtoolnix v85.0.0?

I don't know. The film actually plays but no video shows up.

Were these files modified with FFMPEG 6 or mkvtoolnix v85.0.0?

The file has in fact been modified with mkvtoolnix but v86.

Can you try remuxing it in FFMPEG and see if it suddenly works?

ffmpeg -i input.mkv -c copy output.mkv

To exclude mkvtoolnix I just restored the untouched (at least by me) version and the result is the same: audio but no video.

ffmpeg -i input.mkv -c copy output.mkv

Just started. It'll take a few minutes to complete.

Well I've been fiddling with it for a while. I accidently popped the breaker that the server was being powered with, after that it had a hard reboot and the issue went away.

This'll take ages to complete, not just a few minutes ;)

If it's properly remuxing, I'm surprised it's taking so long. Afterwards can you confirm that it didn't actually transcode the media, please?

I remuxed a 2GB file in about a minute on a notebook i7.

I had accidentally specified two output files.

[ThomasPGH]

The output version is about 12 GiB smaller than the original but the issue persists. Audio plays but no video. The output version only has one audio track, which is the one the input version had as default.

The web player happily plays both versions with video and audio while the Android TV version only plays both with missing video.

I thought I could give this a go too. I shut down the machine, switched it off, and back on again. It did not fix it.

Note that I only got one film with this issue. Others play with video and audio.

@ThomasPGH Does your Tv/device support HEVC level 153? does it also support DV?

I don't know but considering it works with the web player even on Android (not Android TV) this is probably not relevant.

[VampiricAlien]

probably not relevant.

You may find it's very relevant as I have the same issue but with 4K AV1 DoVi.

Anyway 0.17.2 fixes HEVC allowed in transcode profile when not supported,. This might fix your problem.

[ThomasPGH]

Nah, it didn't fix it.
