Performance-wise, there should therefore be no difference to other files when using software decoding, but there is.

Okay, this is kind of hard to describe. I'll give you an example:
I use the following command line (both commands behave nearly identically in this case):
Code:
mplayer -vo vdpau:deint=2 -vc ffh264 <FILE>
mplayer -vo vdpau:deint=2 -vc ffh264vdpau <FILE>
Note that I'm not using any advanced deinterlacing here.
...
Same problem (video and audio out of sync) here. A sample is available at:

http://www.resolutions.it/jerky.ts

It's the same jerky 1080i video captured form DVB-T that displays well on mythtv only since 185.18.14

Bye,
rob

Yau3's problem was different performance when using different de-interlacers with different (earlier) MPlayer versions.

Did you try -mc 2 ?

Oh, my be I have not understand well, but my mplayer problems (compiled from trunk) are related to interlaced content, so I'm incline to think to a deinterlacing issue.
Bye the way, the "slow motion" effect is there even without deint= parameter.

When i read this in the original Yay3 post:

I noticed a strange problem with deinterlacing on one clip I have (1080i60 MBAFF H.264), which was transcoded using x264 from a 1080i60 MPEG-2 source (The source has no problems).

When I enable VDPAU deinterlacing on it, audio and video quickly lose sync (Video plays too slow). In this case it does not matter whether I use software or hardware decoding. I tested this using SVN revisions 28971 and 28950.
I thought my problem was the same...

tried, it seems to improve somewhat, but does'nt fix the problem.

Which proves that we are talking about a very well known, but totally unrelated problem.

I have the jerky.ts file (and many, many other PAFF samples) here, and the A/V sync problem disappears with -mc 2 (I have not yet seen a sample where this is not true).
Another problem might show up: A slight audio delay that you can fix with -delay -0.2 or similar (note that I believe it is not necessary for jerky.ts).

Is the VC-1 interleaved problem fixed in 185.18.14? If not, any estimates on release timeframe?

You are right ( of course ;-) ). Just retried, and noted that there were no more "slow motion" effect but with video only displaced from audio. Applying -delay -0.25 seems an optimal fix.

So the optimal solution in my case appears to be:
mplayer -mc 2 -delay -0.25 -vo vdpau:deint=3 -vc ffh264vdpau <1080i file>

with deint:4 it seems that my 8400gs couldn't cope, as expected.

Many thanks,
rob

Could you point to such samples?

I cannot post a sample for you because it is copyrighted. The bluray in question is "Journey to the Edge of the Universe", (National Geographic). Eac3to output:


TS, 1: VC-1, 1080i60 /1.001 (16:9)

Can you recommend a sample of VC-1 1080i for me to try?

No, sorry. The problem is that it's not easy to find samples. I have only one (from samples.mplayerhq.hu). That's the one i used to implement fields interlaced vc1 in xine-vdpau. But i would like to test it against other samples. No samples, no working code

Although this is difficult to test, I do not know of any issues with the VDPAU drivers concerning interlaced VC-1.
The problem is that such streams are not supported by FFmpeg and, therefore, any FOSS video player (patch welcome, FFmpeg issue 734). So even if any problems were fixed in a driver version, you could still not play interlaced VC-1 streams (except some in xine-vdpau).

hello!
after long time i've to ask again for your help!

i always open and play well m2ts with "AC3 core + trueHD" audio track using mplayer -demuxer lavf -aid n... -ac hwdts,hwac3,ffac3

but not for my last movie! mplayer exits with this strange err:

================================================== ========================
Forced video codec: ffh264vdpau
Cannot find codec matching selected -vo and video format 0x564D4448.
================================================== ========================

if i dont use -demuxer lavf the movie start but no sound i provided. (the m2ts has only one audio track in trueHD format)

in attach nvidia-bug-report and the verbose mplayer output

thanks a lot
