MKV aspect ratio support for MPC?

[kassandro]

So far the Matroska aspect ratio information is only used by the Core Media Player and not by the Media Player Classic, my favorite player. The WM9 aspect ratios should also be supported. So far only the Microsoft's WMP supports the WM9 aspect ratios.

If I'm not wrong , MPC supports wm9 aspect ratio if you are in the good playback mode (for me its VRM9 windowed)
However it happens that the aspect ratio flag is randomly forgotten.
I dont know much about the aspect ratio in MKV but a quick try with vdubmod encoding in xvid 1.0rc3 set to 16/9 aspect ratio and wrapping in mkv didn't work.
(But I couldnt get the file working in TCMP either)

actually i just tried again , disabling ffdshow and it worked perfectly:
encoded in vdub into xvid 1.0 rc3 with a customised aspect ratio saved in just an avi, and the playback is made in the proper aspect ratio in MPC and even WMP.
good stuff!

however the same file wrapped in matroska isnt resized at all.
any idea why ?

:search:

mkv aspect ratio has nothing to do with the ar stored in the mpeg-4 bitstream

Thanks Bond...
Be sure I'm using the search and that's how I found that thread first...
It's just that it's a little bit confusing. I read somewhere that the Xvid flag for the aspect ratio only works in mpeg4 container whereas it perfectly works in a simple avi with any windows player. Then containers also have an aspect ratio flag, so do bitstreams.. I'm already spending a good amount of time on the forums, but I dont plan on living 24 hours into it.
