Question / Help RTSP stream capture - error while decoding MB & adding milliseconds of audio buffering

[CarlosOnline]

Audio is dropping frequently - once per second or so. Lots of glitches. Works fine in original OBS.

Capturing a game video & audio via an RTSP Marshall capture device - . . Log shows 2 main issues: MB decoding errors and audio buffering. Are there any tweaks I can make to eliminate the errors?

Thanks,

Use hardware decoding when available is checked?

Where is that option? I don't see it in any of the settings pages.

I noticed that the audio starts clipping after 10 minutes. So I tried using ffmpeg to record the video and found no audio clipping with ffmpeg. It looks to be a problem with Obs Studio.

ffmpeg.exe -i rtsp://xxx:xxx@10.xxx.xxx.xx/video1+audio1 -vcodec copy -acodec copy -y e:\Video\GameVideo.mp4

Audio starts clipping / dropping after 10 minutes of recording of an RTSP input stream.

Recorded with ffmpeg also and there were no problems.
Original OBS records no problems

FFMpeg repro:
ffmpeg.exe -i rtsp://xxx:xxx@10.xxx.xxx.xx/video1+audio1 -vcodec copy -acodec copy -y e:\Video\GameVideo.mp4
