Hallo > thanks to Alexei I found out I used a wrong bitrate (1510 instead of > 1150) for the stream.

And overshots the target bitrate. Try multiplexing the video as custom VCD (-f2 -b 1500 or a higer bitrate).
Or use mpeg2enc (in combination with mplayer) for encoding the mpeg: mkfifo stream.yuv mplayer -vo yuv4mpeg -noframedrop -noaudio test.mpg & cat stream.yuv | yuvscaler -O VCD | mpeg2enc -f 1 video.m1v And multiplex that video afterwards. BTW: You might have to change the command for mplayer. auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [EMAIL PROTECTED] [EMAIL PROTECTED] www: http://www.lysator.liu.se/~gz/bernhard ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Mjpeg-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/mjpeg-users
