Posted by This is just a remark for me, because occassionally I need to convert mp4/x264 video using DivX codec, but due to random applicability I am not able to remember it. Why DivX? Video encoded by DivX is only one reliable option for me how to stream video from my NAS to TV without any interruption. I am using ffmpeg utility for video conversions, it is a reliable cross platform tool with lot of features and I am mostly happy with it.
So how to do it? Simple run something like following command (the most important bolded):
ffmpeg -i input.mp4 -vtag DIVX -f avi -vcodec mpeg4 -s 640×360 -b:v 1145k -acodec mp3 -ab 128k -ac 2 -ar 44.1k output.avi
Brief explanation:
-vtag DIVX -> force video tag/fourcc to DivX
-f avi -> output in avi format
-vcodec mpeg4 -> DivX is mp4 compatible
-s 640×360 -> frame size
-b:v 1145k -> video bit rate
-acodec mp3 -> audio in mp3
-ab 128k -> audio bit rate
-ac 2 -> two audio channels
-ar 44.1k -> audio sampling frequency
