I am trying to re-streaming my input stream from a cam to the rtmp server ,
and I want to use FFmpeg for this issue, that's why I am using the
following command :
*ffmpeg -i rtsp://root:email@example.com:554/live?tcp -vcodec copy -f
*(I need flesh format )*
but unfortunately it hangs at first and than it has delay about 15 seconds.(
*rtsp://root:firstname.lastname@example.org:554/live?tcp is an input stream from my
cam and **rtmp://xxx.xxx.xxx.xxx/live/teststream are output streams from
the rtmp server** *)
