[FFmpeg-devel] [PATCH] Workaround adjustments for DivX 6.1 and later

[Lord]

Apparently since DivX 6.1, encodes using qpel seemed to cause color
smearing/bleeding when decoding with libavcodec. With some
investigation it turned out that the artifacts are caused by the very
workarounds that were necessary for some old DivX 5 versions.

Uploaded a few sample encodes to:
ftp://upload.mplayerhq.hu/MPlayer/incoming/divx61

This patch adjusts workaround autodetection so FF_BUG_QPEL_CHROMA and
FF_BUG_QPEL_CHROMA2 are not enabled for DivX builds 1814 (6.1) or
newer anymore. The build number was chosen as the first one where
visible problems were experienced, but might need adjustment.
