After upgrading from 0.5-r1 to 0.5_p20373, the -ar audio rate option doesn't appear to be working correctly. It seems to be outputting at half the audio rate that I specify. I'm not positive of this, as I don't have good tools to check what's coming out, but here's what's happening. I have a tospeex command, which does the following: ffmpeg -i - -vn -f s16le -ar 32000 - \ < "$1" \ | speexenc --stereo --le --16bit --rate 32000 - - \ > "$speexout" || exit 1 With the previous version of ffmpeg (0.5-r1), this worked great. However now the audio is 2 times too fast, so I have to change the speexenc --rate to 16000, which then works fine. I wanted to try with the latest svn, but due to x264 version problems gave up.
it appears to be working fine with ffmpeg-0.6_p25423, closing
