Hi still no joy – I’ve tried numerous combinations of options and a few
different transcoding / muxing examples and I’m still getting the same output
Output #0, rtsp, to 'rtsp:// ###.###.###.###:554/live/stream':
True
Stream #0:0True

Could not open 'rtsp://###.###.###.###:554/live/stream': Protocol not found
Still having similar issues with the protocol not found error message
I’ve also tried to just call - avio_check with the following and that’s giving
me the same ‘Protocol not found’ output
const char *fname = "rtsp://###.###.###.###:554/live/stream";
ret = avio_check(fname, AVIO_FLAG_WRITE);
Do you think there is something wrong with the build files I’m using?
Any help much appreciated
Tim

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?
