Unable to play music files

[mjessa12]

I'm receiving the following error when trying to playback my music which I have locally stored on my hard drive. The server information is as follows:

Is there anyway to fix this?

[jjohnson83853]

I'm having the same problem with 10.8.8 with the docker container while trying to play video files. Doesn't seem track recently played videos either.

[Kevinjil]

I also encountered this problem with Direct Play of video files and Live TV from a.o. the Jellyfin Media Player and Android app.

A debug build from source traces the error to:

[17:08:41] [ERR] [11] Jellyfin.Server.Middleware.ExceptionMiddleware: Error processing request. URL POST /Items/a7e1a02b9bbd333e5eed9863f120a201/PlaybackInfo.

   at MediaBrowser.Model.Dlna.StreamBuilder.BuildVideoItem(MediaSourceInfo item, VideoOptions options) in /home/kevin/repository/jellyfin/MediaBrowser.Model/Dlna/StreamBuilder.cs:line 633

The cause seems to be a null reference on videoStream.

After changing the line to:

playlistItem.VideoCodecs = videoStream == null ? new string[] { } : new[] { videoStream.Codec };

The playback issue is fixed.

There's not enough log being included in either comments.

What type of content are you trying to play?

[Kevinjil]

I was trying to play Live TV.

[bugbountyguy]

Just tried to setup a 'live radio' using the docs "Internet radio" section. Was getting the same errors mentioned above, also running docker + 10.8.8. I'll say that the linux jellyfin client doesn't play the music, but the browser does - so it seems like the client also doesn't handle this error (results in 404) correctly or something. Works in the mobile (android) app just fine as well.
