[FFmpeg-user] could not find codec parameters for stream 0 unspecified size

[Ashish Lal]

I am trying to convert a live rtsp stream (H264 + MPEG2 TS ) into MP4 using
ffmpeg. I am getting an error "could not find codec parameters for stream 0
unspecified size".

Any help in fixing this is appreciated.

ffmpeg -rtsp_transport tcp -i rtsp://AA.BB.CC.DD:5555/mpeg2TransportStreamFr
omUDPSourceTest -analyzeduration 999999999 -probesize 99999999 -vcodec
libx264
-s 176x144 -b:v 256k -f mp4 -movflags frag_keyframe+empty_moov op.mp4
