[FFmpeg-devel] [PATCH] Fix distortion problem in MPEG1/2 video

[Heesuk Jung]

Hi Michael,

Thanks for prompt response.
I checked your patch on master branch and have some concern about your
patch.
I'm afraid of performance loss with every pod-encoder avi files.

And so I suggest new idea that we decide full parsing after checking frame
size within some frames.
Please look into my new patch.

Thanks
