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[int­link id=“1414” type=“post”]didn\‘t work with DXVA[/intlink] at all — for­tu­nately build 3949 does­n’t suf­fer this issue. I also[int­link id=“919” type=“post”]previously had a problem[/intlink] 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.

Sorry for the ques­tion, but did you know FFD­Show has a GUI with a lot of set­tings? F.ex. you can switch on or off DXVA sup­port, in case some files are not com­pat­ible with it. Also, you can set it up to try to do it automatically.

Thanks you, yes I did. I’ve used them extens­ively to tweak the sub­title set­tings. I require DXVA as the E350 CPU in my HTPC is too under-powered to decode full 1080p BluRay’s on the CPU. I use ffd­show spe­cific­ally because it sup­ports DXVA and sub­titles which is some­thing I can­’t do with oth­er decoders.
In my exper­i­ence with ffd­show try­outs files aren’t incom­pat­ible with it, so much as cer­tain revi­sions of it are incom­pat­ible with some files. This isn’t all that sur­pris­ing giv­en that it is in alpha or beta stage constantly.
Any­way, for now my recom­mend­a­tion for build 3949 stands — it works well with all the files I’ve tried it with — and it does so with lower CPU usage than any oth­er build I’ve tried — which is most of them.
