FFdshow problem & feature request

[CavalloPazzo]

I've encoded a film and saved a preset file with a previous version of the ddshow filter. Now when I try to open the preset file, the player (tried zoomplayer and mediaplayer) crashes. I attach the preset file (I've added a .txt extension to post), so you can test if the problem exists only on my machine or not.

Now the feature request... It's not easy to explain, and maybe I'm totally wrong, anyway I'll try to be clear and explain my idea.
Sometimes when I encode a film, I can see pixelation on blue or red part of the movie... this should be due to the colorospace used (YV12), that subsamples the croma channel. When we watch the encoded clips, the chroma channel is resized to fit the luma channel (I think). Anyway it seems no interpolation is done and so it's possible to see pixelation in area with a lot of saturation. So (I repeat... I may be totally wrong) could a different resize algo (bilinear or bicubic) be applied to resize the chroma channel?

Thanks in advance 4 your reply

P.S. Will you open an opensource page even for FFVFW?

Sorry, the is no attachment. Could you please send the preset file directly to me (cutka@szm.sk)?

And about your feature request. I know what you mean, but I don't know if I can solve it. Today colorspace conversion from YV12 is done mostly by graphic cards and not the decoder itself. I could try to use xvid (or mplayer) colorspace conversion routines to convert YV12 to RGB, force RGB output from ffdshow and see the results.
