Which card for 1080p 60fps H.264 playback?

[pugz]

I'm building a HTPC box under Linux and will be getting a Panasonic TM-700 camcorder capable of producing 1080p at a full 60fps (H.264). I would like the box I build to be able to playback these videos smoothly.

I have two questions:
1) what card can support this (I was hoping a GT2xx would be sufficient)?
2) can a core i3-540 CPU handle this decoding by itself?

Thanks.

Currently none, afaik.

Certainly (depending on software, post-processing and video output).

Most of the vdpau "c" cards should be able too.

MPEG DECODING (1920x1080): 100 frames/s
MPEG DECODING (1280x720): 232 frames/s
H264 DECODING (1920x1080): 66 frames/s <-------
H264 DECODING (1280x720): 140 frames/s
VC1 DECODING (1440x1080): 83 frames/s
MPEG4 DECODING (1920x1080): 72 frames/s

Looks like a GT240 should suffice.

Works well on the lowly gf210 (even my integrated 8200 could do it).
But i recommend a gf220 at least.

Thanks for all the info guys!

No.

H264 DECODING (1920x1080): 66 frames/s

It's not only about decoding (that is what qvdpauinfo tests), but you need to read the file, demux it, play audio, keep A/V sync, etc.

Above value corresponds to app. 50 fps

I can confirm that it does not work on a G210, and the values from a GTX 580 look very similar, Carl Eugen

Well I got a file from that camera. If you leave it in the native raw file your right, in linux it doesn't cope with it well. However I dropped the same file in VideoRedo 4, selected quickstream fix, and that resulting file was easily playable with vdpau 1920x1080@60fps with 0 frame drops. No re-encoding needed. (Same trick I have to do to get Hauppauge HD PVR recordings to seek properly without re-encoding)

Could you test with xacti_hd2000_dogsample20090207_2a.mp4 in http://samples.mplayerhq.hu/HDTV/ and upload a "fixed" version?

Thank you, Carl Eugen

VideoRedo won't bring in MP4 containers.

Then perhaps another sample that was "fixed" by VideoReDo?

Thank you, Carl Eugen
