Videostream-cli webcam to another videostream-cli not working

Thank you for this amazing package.

I am trying to use this package for streaming on raspberry pi to Ubuntu machine receiving frames and handle it with opencv like in server example. Tried those on raspberry pi:

1. Server example works fine
2. Webcam works fine
3. Videostream-cli example, streaming an mp4 video works fine and timing is correct But running videostream-cli with webcam instead of video doesn’t work, I receive first one or couple of frames correctly then the stream get stopped hang or receiving curropted frames.

• I had tried different type of cameras
• and test on raspberry pi 3 and 4
• tried different versions of ffmpeg even downloading source and compile it Non of them was able to stream successfully.

Why is this happening since both sever and webcam both works fine, means PYAV and FFMPEG installed correctly.

This how I am running videostream-cli: on raspberry pi: python cli.py offer and this how I modified the code to make offer stream from webcam:

# create media source
    if args.play_from:
        player = MediaPlayer(args.play_from)
    else:
        if args.role == "offer":
            options = {"framerate": "30", "video_size": "640x480"}
            player = MediaPlayer("/dev/video0", format="v4l2", options=options)
        else:
            player = None

on Ubuntu machine I run python cli.py answer --record-to video.mp4

No I do not have a raspberry pi. Bear in mind this is my free time I’m giving at no charge. Don’t expect me to go out and buy gear to reproduce issues.
