hi I download 2005-06-25 cvs version of ffmpeg,compile with "./configure --enable-xvid --enable-gpl --disable-vhook" in Cygwin.When I using this command line: ./ffmpeg -i c:/a.asf -vcodec xvid -s 320x240 -r 15 -b 216 -acodec pcm_alaw -ac 1 -ar 8000 -f mov c:/cygin.mov QuickTime Player can play it very well. But when I using command like this: ./ffmpeg -i c:/a.asf -vcodec xvid -s 320x240 -r 15 -b 216 -acodec pcm_mulaw -ac 1 -ar 8000 -f mov c:/cygin.mov QuickTime Player fail to play it and without response. So my question is: Is pcm_mulaw codec in ffmpeg compatible with quicktime's ulaw codec? Thanks in advance.
