0codecsComplete codec setup guide for Windows 78

Win­dows 8 is fin­ished and will soon be avail­able for retail sale. With that in mind it seemed a good time to write an updated guide to get­ting codecs set up for a fully oper­a­tion­al HTPC for both Win­dows 7 and 8. For this guide I’m using a new fea­ture of HTML5 which cre­ates expand­able instruc­tions. At the time of writ­ing this is only sup­por­ted by chrome and safari 6 but hope­fully oth­er browsers will add sup­port in the near future.

0Media Player Classic - Home Cinema LogoDecoding Interlaced VC-1 with DXVA

A couple of days ago ver­sion 1.6 of Media Play­er Clas­sic — Home Cinema was released.  Although I don’t use MPC-HC, I do keep an eye on the releases as it can be a use­ful back-up when a file wont play.  It’s been quite a long time since the last offi­cial release so I had a quick scan of the changelog and one thing imme­di­ately leaped at me: “VC-1 DXVA Decoder now decodes VC-1 inter­laced mater­i­al”.  Until now there has been no open source x64 codec that will decode inter­laced VC-1.  Finally hav­ing this avail­able com­pletes cov­er­age for all the media files I have ever tried to play.  Hope­fully this will also get added to ffd­show try­outs and LAV Video in the near future.

0Haali Matroska logoHaali Media Splitter: Official Site Down

HTPC related sites and resources seem to be drop­ping like flies at the moment.  First Media Cen­ter Stu­dio dis­ap­peared, then TheHTPC.net developed prob­lems, and now the offi­cial site for Haali Media Split­ter is down.  For­tu­nately the media split­ter can still be down­loaded from lots of oth­er sites, and we will keep a mir­ror here in case oth­er sites drop it.  There are also altern­at­ives, includ­ing the MPC-HC stan­dalone codecs and LAV.  Links to these are avail­able on our down­loads page.  Lets hope that this is the last in the recent series of HTPC related losses.

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

0FFmpeg LogoLAV — A new splitter

A new dir­ect­show split­ter has become avail­able.  If you’re not happy with the offer­ings from Haali and Gabest then you might like to try LAV.  I haven’t tried it myself yet, so I can’t cur­rently offer any more inform­a­tion.  It does men­tion split­ting wtv files though, so I will be try­ing it in the near future.

2Windows Media Center eHome LogoFull 7MC codec setup

I’ve pre­vi­ously pos­ted sev­er­al times about codec issues on 7mc, but I’ve now got a solu­tion that is com­pre­hens­ive, fairly simple and works con­sist­ently.  With a few free codecs and util­it­ies you can have full decod­ing sup­port, DXVA, sub­titles and fant­ast­ic flex­ib­il­ity work­ing in 64bit (or 32bit) Media Cen­ter.  The fol­low­ing instruc­tions are spe­cif­ic to the x64 edi­tion, but should work just as well on the 32bit edi­tion.

0Haali Matroska logoProblems with DS splitters playing a range of m2ts files

Ever since set­tings up a HTPC run­ning Win7 Media Cen­ter I have had the occa­sion­al prob­lem play­ing m2ts files. ffd­show sup­ports all of the codecs used in m2ts files but still a few files play without without either audio or video, or the play­back isn’t smooth des­pite more than ample hard­ware. I have exper­i­mented extens­ively with both haali matroska split­ter and gabests mpeg split­ter but both have their flaws.
