Originally created by @YannickPerret on GitHub (Oct 14, 2024).

Hello,
I've launched two streams on my rock5b+:

  • the first is a tee stream with 2 outputs for twitch (on two different twitch channels)
  • the second is a single stream for twitch (on a different channel from the first stream).

Both had the stream_loop parameter set to -1.

It's my stream that has the single stream that has crashed

When the stream was at around 6:8, I received this message telling me to report the bug:

Please provide a video file that can be used to reproduce the problem and a complete ffmpeg command. I don't have your environment.

Also make sure you build using the mpp repo mentioned in the Wiki, not the outdated mpp library provided by the SBC vendor.
