Hello @zoombinis . Unfortunately this package is just a wrapper of the OpenCV API, which itself, wraps a few backends (uses whichever you have available) to offer its functionality.
If I google one of those errors I get results like:
- Having a too-slow consuming part of the RTSP stream gives more errors If the computer where you are running this is not able to deal with the uncompression of the h264 stream (does video_stream_opencv consume a lot of CPU in your machine?) may be that. That thread also talks about adding
?tcp
to the stream to force tcp to not have corrupted frames (but gives delay apparently). - This other thread talks about ffmpeg having issues with RTSP via udp, another issue in this repo reported a way to switch to UDP instead: #86 but maybe it contains enough keywords to find some workaround here
You could also try to use the ROS package gscam instead of this one. Good luck!
