[Ffmpeg-devel] Optimizing encoding when knowing changed area
Mon Oct 10 08:09:10 CEST 2005
I use ffmpeg to encode graphics animation produced by another program. The
contains API interface that allows to get output pixmap in RGB format and
changed area, for example (100, 100) - (200, 300).
When encoding MPEG using FFMPEG I simply convert changed area from RGB to
YUV each 1/30 of second. But often nothing was changed or only some small
rectangle was changed. Are there any way to use knowledge about changed area
to optimize encoding?
