[Libav-user] Missing RTSP protocol?

Hi, thanks for the response and clarification on the rtsp being a demuxer (not sure how I missed that).

I’ve been able to get an rtsp stream working from the command line using the following command

.\ffmpeg.exe -rtbufsize 1500M -f dshow -i video="screen-capture-recorder" -pix_fmt yuv420p -vsync 1 -vcodec libx264 -r 23.976 -threads 0 -b:v: 1024k -bufsize 1024k -preset veryfast -profile:v baseline -tune film -g 48 -x264opts no-scenecut -acodec aac -b:a 192k -ac 2 -ar 48000 -rtsp_transport tcp -f rtsp rtsp:/<server-ip><port>/live/myStream

I don’t currently have all of those options set in my AVDictionary (options) so I’m going to have a play with setting a few to see if I can get it running.

I’ll update later with any progress

rtsp is a demuxer, it uses either the udp or the tcp protocol.

Does the stream work with the command line interface?
