Hello!
I'm using ffmpeg to create mjpeg stream from mpeg4 stream coming from an
IP-camera.
ffmpeg input is depacketized/unpacked mpeg4 rtp stream. I'm using the
following parametrs:
ffmpeg -f 'm4v' -i "rtp://127.0.0.1?localport=5000" -f mjpeg -s 240x180
-r 12 -sameq -
It worked with version 0.49, but not with version 0.5.
My program starts sending the depacketized/unpacked m4v data from the
first VOS header,
but ffmpeg starts to encode 10 seconds after. The starting frame rate is
high (above 30), and it's getting lower and lower, ( under 1 - 2 fps ).
Am i using wrong parameters or configuration, or might it be a bug?
