Windows 8 Support in MP4 filters

The MP4 filters at www.gdcl.co.uk/mpeg4/ have been updated with the following changes:

• There was a small bug in the demux that prevented connection to the Microsoft DTV-DVD video decoder on Windows 8 (the biSize field was left zero). This is now fixed.
• Encoders that supplied H264 byte stream format with an MPEG2VIDEOINFO descriptor would cause the MP4 Mux to think that the data was length-prepended format and create an invalid MP4 file.
• Several people reported that the MP4 mux would fail if upstream filters returned an error from GetPreroll.
