Originally created by @Hendi48 on GitHub (Feb 11, 2022).

I'm facing an issue where playback on my client device stops after a couple minutes. Upon investigating a network trace, I found that Kestrel ends the HTTP response with \r\n0\r\n\r\n after 0x8590000 bytes have been read from the transcoded file. Incidentally this seems to fit pretty well with the timestamp at which the ffmpeg process ends after finishing transcoding. The file has its full size in the cache dir and is not deleted prematurely. It still exists as of now, 45 minutes after playback was interrupted. I copied the transcode to my local machine and it plays back fine at its full length.

I'll do some more digging tomorrow and check whether the interruption really coincides with ffmpeg exiting.

Media Info of the file

Matroska container, 720p h264 video, 2 EAC3 audio tracks, see ffmpeg log below for details.

Originally created by @Hendi48 on GitHub (Feb 11, 2022). I'm facing an issue where playback on my client device stops after a couple minutes. Upon investigating a network trace, I found that Kestrel ends the HTTP response with `\r\n0\r\n\r\n` after 0x8590000 bytes have been read from the transcoded file. Incidentally this seems to fit pretty well with the timestamp at which the ffmpeg process ends after finishing transcoding. The file has its full size in the cache dir and is not deleted prematurely. It still exists as of now, 45 minutes after playback was interrupted. I copied the transcode to my local machine and it plays back fine at its full length. I'll do some more digging tomorrow and check whether the interruption really coincides with ffmpeg exiting. **Media Info of the file** <!-- Use the Media Info tool (set to text format, download here: https://mediaarea.net/en/MediaInfo) or copy the info from the web ui for the file with the playback issue. --> Matroska container, 720p h264 video, 2 EAC3 audio tracks, see ffmpeg log below for details. **Logs** <!-- Please paste any log messages from during the playback issue. --> ``` [2022-02-11 00:34:29.998 +00:00] [INF] [90] Jellyfin.Api.Helpers.TranscodingJobHelper:

@Hendi48 commented on GitHub (Feb 11, 2022):

Yes, this is definitely a bug with waiting for the ffmpeg process and then ending the HTTP connection. I sent SIGSTOP to the ffmpeg process to freeze it, and playback on the client continued way past the point where it normally stops.

I was also able to reproduce it with VLC by opening the stream.ts link there. Stops when ffmpeg is done.

Regression introduced by ca887518dd. KeepReading will return false when the job has exited, despite there being many bytes left to be read in the stream.
