[FFmpeg-user] ffmpeg fail to open rtsps stream on rapsbian

[ben pecheux]

Hi

I am trying to capture a rstps video stream from an arlo camera using
ffmpeg using the command below on raspbian stretch.

*ffmpeg -re -i 'rtsps://<arlo_cam_url>' -acodec copy -vcodec copy test.mp4*

The command fail with an "operation not permitted" message and nothing else
(See raspbian output below). I am not sure what is missing or if I am using
a version of ffmpeg that does not support rtsps streams or if I am missing
codecs or some protocol support. I tried the same command on my mac and it
works (see mac output below)

Thanks

Ben
