[Fame-devel] YUV MPEG encapsulation

[Thomas J. <to...@si...>]

Hi!

Many people re-encode non MPEG 1/2 data to MPEG-1/2 when using mplayer
with their dxr3 (http://dxr3.sourceforge.net) video card.

This has two major drawbacks:
1. Quality loss because of the re-compression
2. CPU time lost for the re-compression

I'm currently (re-)writing a patch for SDL (http://www.libsdl.org)
to add dxr3 support by generating MPEG frames.

While coding I had the following idea:
Would it be possible (and fast?) to just encapsulate the YUV (even RGB?)
data as MPEG frames with nearly no compression applied?

As I don't have any (real) knowledge about the internal workings of MPEG,
I thought this mailinglist is the best place to ask :-)

Thanks in advance and cheers,
Thomas
