rtsp h264 / 265 performance

[MyraBaba]

Hi,

I am working on the efficiently decoding rtsp stream for processing with in the opencv. Not %100 related this codes but can be informative for all of us.

I have 4 rtsp stream h264 1080p and I need only 15 fps for each of them. what will be the best and efficient way to this without diving the low level C/C++ ? compiling gstreaming or ffmpeg on the working machine ie enough ?

And I have below error in my RPi4:

./hello_drmprime jellyfish-5-mbps-hd-h264.mkv

I don't see an error there - I see normal status lines.
Whilst I agree that what I think you want should be doable I'm not certain that you are going to get it with existing applications.
