Prepare your video with your distrib ffmpeg version or avidemux. They should be in xvid with noaudio, example ffmpeg line:
ffmpeg -i in.mov -vcodec libxvid -qscale 1 -g 128 -me_method epzs -bf 0 -mbd 0 -aspect 16:9 epzs_128_out.avi
DataMosher can chain several video file with the same codec and size:
./datamosher -i v1.avi v2.avi -p -z 2
DataMosher can record the output in ffv1 format:
./datamosher -i v1.avi v2.avi -p -z 2 -o out.avi
