 I am trying to send and receive a webm file (only video) through a rtsp
 tcp tunnel with the following command line, but the receiver part produces
 an empty file:

 Receiver site:
 {{{
 C:\temp\recv>ffmpeg -v 9 -loglevel 99 -report -y -f rtsp -rtsp_flags
 listen -rtsp_transport tcp -i rtsp://127.0.0.1:23020/live.sdp -vcodec copy
 -an out.webm
 }}}

 Transmit site:
 {{{
 C:\temp>ffmpeg -v 9 -loglevel 99 -report -i small.webm -vcodec copy -an -f
 rtsp -rtsp_transport tcp rtsp://127.0.0.1:23020/live.sdp
 }}}

 The same, but with mp4 files, instead is (correctly) working.

 Receiver site:
 {{{
 C:\temp\recv>ffmpeg -v 9 -loglevel 99 -report -y -f rtsp -rtsp_flags
 listen -rtsp_transport tcp -i rtsp://127.0.0.1:23020/live.sdp -vcodec copy
 -an out.mp4
 }}}

 Transmit site:
 {{{
 C:\temp>ffmpeg -v 9 -loglevel 99 -report -i small.mp4 -vcodec copy -an -f
 rtsp -rtsp_transport tcp rtsp://127.0.0.1:23020/live.sdp
 }}}
