Force FFMPEG to use TCP protocol when reading a RTSP Stream
7 juin 2016, par gary_starI’m running
ffmpeg
(Windows 7, 64bit) from command line to get a frame from a RTSP stream (second channel from my DVR) :ffmpeg -i "rtsp://xxx.xxx.xxx.xxx:554/user=xxxx&password=xxxx&channel=2&stream=0.sdp" -rtsp_transport tcp -y video.jpg
After running, it waits for about 10 seconds and then i get :
[rtsp @ 026fd840] UDP timeout, retrying with TCP
After another long wait (2 minutes or so), i get :
[rtsp @ 028dd840] Could not find codec parameters for stream 0 (Video: h264): unspecified size
I read somewhere that I have to force using TCP, because changing from UDP to TCP will not work.
I don’t understand why
-rtsp_transport tcp
is not working.I’m using
