[FFmpeg-devel] Accelarated MPEG2 to MPEG4 transcoding
Mon Aug 13 13:45:26 CEST 2007
Hello beloved FFMPEG developers!
Recently I found this paper:
Which describes how to get motion vectors from mpeg2 stream and re-use
them when transcoding to mpeg4, as also other information. The time
saved is over 60%.
So my question is currently ffmpeg using any of the mpeg2 information
when transcodign to mpeg4 or it is doing raw encoding?
