Hey.
I'm trying to convert an .avi file to .flv using ffmpeg-php on a centos 5.4 server.
This is my code:
exec("ffmpeg -y -i " . $srcFile . " -ab 32 -ar 22050 -b " . $newBitrate . "k -vframes 2500 -qscale 7 -f flv -s " . $newWidth . "x" . $newHeight ." " . $destFile);
For some reason the video length in the new .flv file is corrupt or missing for online players unless I disable audio (with -an). The video plays but players do not show the progress correctly.
Plus I cannot change the audio bit rate and sample rate - it just will not work then - for instance when I replace the numbers with 128 / 48000 (from original .avi).
