the command line that I used to generate the above ffmpeg output, which is also contained in the test.sh script in the linked tar.bz2 file, is: ffmpeg -r 60 -i ./test/%07d.bmp.png \ -i ./test.wav \ -b:a 128k \ -b:v 9000k \ -c:a libvorbis \ -c:v libtheora \ -g 200 \ test.ogg sincerely, --Robert McIntyre
