Transcript: Queue is stuck when FFmpeg overlay failed

[limjoe]

Describe the bug
Use Camera to forward the AI HLS overlay stream, when occur some error, the AI transcription seems to be blocked, and no more transcription result, and the Live Segments Queue became more and more longer

It seems that the original live stream is interrupted for a moment, then pushed the stream again.

Then I suspected that there was an interruption in the original video stream, but I watched the video through Whep and during this period, the video played normally and it seemed to have no interruption

Version
v5.14.22, with this PR #193

To Reproduce
Steps to reproduce the behavior:

1. Go to transcript
2. Click on start Transcription
3. Go to Camera
4. Use the latest AI Transcrition transcript live stream with subtitle url as source, and forward the AI stream to third SRT server, SRT server can use Restreamer.
5. Click Start Live, run for a while.
6. See error

Expected behavior
AI transcription is running normally

Screenshots

Additional context
The Oryx logs as below, it seems that the source stream is unpublish, but after a while the origin stream is recoverd.
node1. xxxx. com is the replaced content

Oryx.txt

The Oryx_2.txt is another test, and has more logs.
Oryx_2.txt

[limjoe]

I rolled back my Oryx container version to v5.14.19, and without my PR modify, and there is the same issues.

[limjoe]

And the queue ts file order maybe looks like this.

Caused by the overlay command failed when driving fix queue:

it seems that if one ffmpeg command failed, then this failed ffmpeg will keep trying again, which will cause the entire queue to appear to not continue running

There is no problem with streaming with vMix and OBS

I found that when AI subtitle stream, such as live/livestream, is pushed back to the same Oryx ai/livestream channel, AI transcription will use the slices of the ai/livestream channel for translation. During the operation, some of the ai/livestream video slices will cause ffmpeg to fail, leading to this problem
