I have a usb camera '/dev/videoX' and I've implemented decoding process. Supported camera framerates are 15 and 30. However, I need to reduce its framerate in order to stream video data (RTP/RTSP) from multiple usb cameras (I have 4 cameras) using H.264 codec and keep quality as good as possible. Also it is essential to be in real-time (small delays). I've been searching on how to reduce the framerate of the output stream, for example to 5 fps. And I know that in order to reduce the framerate in CLI (ffmpeg) '-r' flag is used.
And my question is how '-r' functionality is implemented? Is it filter (AVFilter) or some kind of algorithm? Thanks. _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
