Are there testcase known that the other patches improve ? (such testcase would be usefull for fate for example) [...]

The file - afaict - is related to the patchset as a whole. The current version of the patchset does not fix the file though, so I believe we should wait for a new version of the patchset. The sample is >20MB, most of the reference files are very small, so perhaps we can avoid using this one. Carl Eugen

In my view, there is no need to wait for a new patch set. I will just submit a new patch for that issue. Regards, Jerome

For interlace field pictures s->mb_height indicates the height of the full picture in MBs, i.e. the two fields combined. A single field is half this size. When calculating mquant for interlace field pictures, the bottom edge is the last MB row of the field.
