If you read a file, you don't need to specify any codec.

If you write to a file, I think you need to specify X264. Full list of FOURCC codes avaliable here.

I can only advice you to experiment with different FOURCC codes or try to save file with .mp4 extension. Also you can try AVC1, it's an apple format. – vyndor Jun 07 '13 at 16:35

Here is a much longer list of the FOURCC codes of other codecs. http://www.fourcc.org/codecs.php

Since you want to use H264, you can use H264 or X264 as the FOURCC codes.
