Hello,
I am trying to open a PTZ Camera on a MAC machine. I get the following errors:

@shersoni610 I don't think, FFmpeg directly supports PTZ camera You need to setup RTSP stream to be able to open that camera and use that RTSP stream address in FFdecoder.
But why integer index fails with the software. It works fine with opencv.
It works fine with opencv.
@shersoni610 That's because OpenCV supports backends other than FFmpeg, like Gstreamer and v4l2 etc., which supports these cameras. But DeFFcode is made entirely to work with FFmpeg backend only.
I was able to use ffmpeg -i 0:0 to get images from the camera

@shersoni610 Paste the output of ffmpeg -i 0:0 here.
