2FFmpeg LogoFFDShow DXVA H.264 corruption resolved

I have recently been suffering corruption playing back some H.264 files with FFDShow tryouts.  After a bit of experimenting I’ve found that the last build without this issue is build 3949 from 24th-July.  I previously had issues with earlier releases of FFDShow that didn\’t work with DXVA at all – fortunately build 3949 doesn’t suffer this issue.  I also previously had a problem where some builds of FFDShow were less efficient on my HTPC and were unable to smoothly decode some high bitrate movies, e.g. a rip of the Inglorious Basterds Blu-Ray, which has forced me to continue to use an old build from mid-2010 until now.  Build 3949 doesn’t suffer from these issues either – so in terms of the 3 problems I’ve had over the years with ffdshow, build 3949 doesn’t suffer from any of them, making it my build of choice for the foreseeable future.

0FFmpeg LogoUnsolved: Decoding interlaced vc1 in Media Center x64

Whilst my MediaPC setup can decode just about everything thrown at it, I have had problems decoding interlaced VC1 content.  The problem is caused by the failure of ffmpeg to support interlaced vc1.  Whilst there are other codecs (e.g. cyberlink or arcsoft) these are currently not available as x64.  Cyberlink do have an x64 codec for h.264 and mpeg2, but I haven’t been able to get it to work with VC1 content.  Hopefully ffmpeg will fix interlaced vc1 support soon, but as its been on the to do list for over 2 years I’m not holding my breath

0Quizdom LogoQuizdom tablet “video capture” not working

I was asked to investigate why some video capture utility which is part of the software package for the Quizdom Tablet wasn’t loading correctly on a particular laptop. Investigation revealed that quizdom used the XviD codec and installs it as part of its setup routine. The laptop in question already had a video codec installed that was capable of decoding XviD videos, and this prior codec had a higher merit than the XviD native codec installed by quizdom. Disabling XviD support in this codec proved to be the solution. Anyone with the standalone MPC-HC codecs or ffdshow installed may come across this problem

1Closed Captions Subtitles LogoSubtitles and DXVA in Windows Media Center 7 x64

Thanks to a guide on theHTPC.net I have been able to get subtitles working with hardware accelerated decoding in Windows Media Center 7 x64.

For this simplified guide to work you must already be comfortable with the various tweaks necessary to change the default codecs used in Media Center. Once you know how to tweak codecs (and change their merits) you can simply follow these steps…
