Hello,
Working on a video player that should be able to play anything ffmpeg can, I am
looking at how VLC accepts stream URLs with all kinds of stream modifying
parameters. (I am also reading the VLC developer documentation…)
When a URL of a form similar to this is sent to avformat_open_input(), are the
additional URL parameters observed and used?
rtsp://[camera-ip-address]:554/axis-media/media.amp?videocodec=h264&compression=90
I understand how the camera will use those parameters when generating the
stream it generates, but will underlying logic within or called by
avformat_open_input() additionally see those parameters and use them during the
format probing discovery of the stream?
Or does my logic need to observe that there are URL parameters, and then
generate AVDictionary entries matching the intent of the parameters, passing in
the additional URL parameter settings via the AVDictionary parameter to
avformat_open_inout()?
Thanks for any tips,
