[Ffmpeg-devel] [PATCH] fast h264 decoding

[Reimar Döffinger]

Hi,
I created a little patch that finally allows me to play Apples HDTV
trailers realtime, by using -lavdopts fast in mplayer.
It disables the deblocking step when fast is set, for the samples I have
it doesn't make a visual difference, but decoding time goes down from
17.017s to 9.783s.
Please consider it.

Greetings,
Reimar D?ffinger
