[FFmpeg-user] ffmpeg + rtsp results in log output not displaying frame size nor bitrate

Sun Feb 12 21:40:43 CET 2012

So after figuring out how to force ffmpeg to push rtsp over tcp (which wasn't clearly documented...), but now I'm noticing that the output log isn't showing frame size or bitrate deltas.

frame=1221110 fps= 29 q=36.0 size=       0kB time=11:18:22.36 bitrate=   0.0kbits/s dup=1220 drop=0
frame=1221125 fps= 29 q=36.0 size=       0kB time=11:18:22.86 bitrate=   0.0kbits/s dup=1220 drop=0
frame=1221140 fps= 29 q=36.0 size=       0kB time=11:18:23.36 bitrate=   0.0kbits/s dup=1220 drop=0
frame=1221156 fps= 29 q=36.0 size=       0kB time=11:18:23.90 bitrate=   0.0kbits/s dup=1220 drop=0
frame=1221171 fps= 29 q=36.0 size=       0kB time=11:18:24.40 bitrate=   0.0kbits/s dup=1220 drop=0

Using the following command:

./ffmpeg -i $SOURCE -threads 2 -b:v 500k -bt 500k -deinterlace -r 30 -vcodec libx264 -b:a 64k -acodec libfaac -ar 44100 -s 720x480 -x264opts keyint=30:min-keyint=15 -f rtsp -rtsp_transport tcp -muxdelay 0.1 "rtsp://$USER%40$DOMAIN:$PASS@wowza.server.com/stream/path.sdp" 2> ./ffmpeg-log.out

I get the following output:

I'm pushing the output stream to wowza and this is working, but I'm concerned about this bitrate issue.

I'm not entirely sure where else to look at the moment, but it would be nice to be able to see 'what' bitrate ffmpeg thinks it's encoding at while streaming.

Thoughts?
