Playing H264 with 59:36 or 16:15 (PAL DVB source) with right aspect ratio ?

[Setsunaaa]

DVB-S recordings are 720x576 or 460/468x576, encoding pixel ratio is 16:15 or 59:36 (encoding to avi in virtualdub-mpeg).
Muxing to mkv (h264/ogg), giving the right pixel ratio there too.
But MPC fails to play it right, the .avi and the .mkv are played in 1:1 ratio, I have to override it within MPC.
VLC player plays the aspect ratio in both cases right, but fails to play the video smoothly (doesn't seem to like my encoding options, less than 10% cpu usage during play with both players).

So: Is the MPC+x264 playing problem caused by ffdshow (lastest from x264.nl) or by MPC itself? If it is ffdshow, what setting is wrong, can I correct it?

PS: no vfw-or-not replies please, it is a sooo useless fight (and I do use vfw for my lazyness).

Hi and welcome to the forum...

If you want FFdshow to display your anamorphic encodes correctly, you need to make sure the following options have been selected: -

Ah, "Overlay Mixer", I had that option off (everything else was right already).
I once had subtitle-play problems with an older ffdshow version, and that change was still active.

Thank you for that short-and-sweet answer.
:thanks:

As an alternative, you could use CoreAVC, which properly handles aspect ratio flagging also.

I wont go away from x264 so soon.

I even used mpeg1 video since I still could get better quality (ignoring the filesize) until xvid was 1.1alpha, and later I stumbled over x264 (somewhat version 460 by that time).

DivX was never used by me, the quality was never good.

I doubt that coreav can be so much better, my x264 settings are tuned quite nicely, the musicvideo.mkv takes less (usally 1/2) space than the original audio track on a CD, 25fps DVB-S full PAL. Even in frame-by-frame view it is hard to find artifacts like in xvid or mpeg1.

Only Alpha Centauri recordings are compressed higher (a German educational Astrophysician who does his explaining VERY nice).

CoreAVC is a decoder, x264 is an encoder ;)

Whoops, dumb me.
Hm, but I still don't see a reason for using something else for decoding h264, is there some difference in picture quality?
Note that I don't care about cpuusage etc, only about picture quality.

Note that I don't care about cpuusage etc, only about picture quality.CoreAVC's decoder is one of the fastest, if not "the" fastest MPEG-4 AVC decoder currently available. And does this while remaining very accurate ;)

It also offers you the ability to decode high-def sources with much lower speed CPU's.
