I see that on http://www.free-codecs.com/FFDshow_download.htm the latest version of ffdshow has codecs for H264

. Does this mean that a system could be created using entirely free software (ffdshow and say MythTV ?)
Has anyone gone down this path ? How did it go ?
Thanks

i've been using ffdshow to decode h.264 for a couple of years now i think. it works fine for the lower bitrate stuff but for higher bitrates - e.g. freeview - you really need a codec that hands off to the GPU. mpc home cinema also has a free h264 codec and there are a few others out there too.

ffdshow (now ffdshow tryouts) has been able to do h264 for years as mentioned. Its not a new feature, and as above it uses the CPU rather than the GPU for decoding, so much less smooth. DXVA is what you want, and that's what powerdvd8, arcsoft and media player classic home cinema codecs offer. The latter is open source and free, but doesnt play nice with other software such as mediaportal.

Also ffdshow + mythtv makes zero sense, since ffdshow is a directshow filter for windows, and mythtv is a media centre application for linux.

gbpvr is a very good freeware application that leverages the GPU capability of your video card to hardware acceleration. Well it's not freeware but optional shareware so it's not crippled if you don't contribute. But it's worth contributing to IMHO

Does GB-PVR come with built in DXVA codecs for gpu accceleration now?

It doesn't come with them itself but will use the features in the drivers for your video card. There's been plenty of conversation on this board about how to enable GPU acceleration on gbpvr.

Oh, then thats the same as i thought it was, and the same for other software such as mediaportal. Nothing special.
