Michael Niedermayer	09ec182864	avcodec/msmpeg4dec: Skip frame if its smaller than 1/8 of the minimal size Frames that small are not valid and of limited use for error concealment, while being very computationally intensive to process.

Michael Niedermayer	5e50a5724b	Revert "removing lowres support" There have been multiple user complaints about loosing this feature while its not clear the 3% speedloss claims where real or fabricated. My own testing indicates no statistically significant speed difference both with mpeg2 and mpeg4, and if at all the code with lowres support is a tiny bit faster than without. This reverts commit `92ef4be4ab`, reversing changes made to `2e07f42957`.
