[Mplayer-dvb] High Quality Playback

[Arpi]

Hi,

> just a question ! What do you think, will it be possible to get high quality playback of divX files via the dvbs card, using current CPUs ?

> (4) ENCODE - encode to mepg1 or 2 frames

I can play dvd-sized divx diles with about 70-80% cpu usage on an
overclocked celeron2-800 @ 1066 Mhz. But I have only 1,2 and 4, so
no resize. I don't need it...

postprocessing must eb done before teh resize. 2 reason:
- postproc is built-in into te codec - you can't insert resize code between
decoding and postproc
- postproc works on 8x8 blocks, depending qscale info from codec. if you
resize, this won't work...

yes. at least wo. resize.
