[mpeg2-dev] libmpeg2- license and other

[azer <aze...@if...>]

hi

i search codec source for read mpeg.

My purpose it's incorporate this library in the project "blueos" an 
alternative to beos.

i search then free codec (as lgpl, bsd,...) to read/write most popular 
media file.

it's possible to use it. ?

libmpeg2 and mpeg2dec are licensed under the terms of the GPL, not the
LGPL. I think this is free enough for most opensource projects. This
is becoming a FAQ lately.

Also libmpeg2 only reads mpeg2 streams.

Is this the best that god can do ? Then I'm not impressed.

Hi,

and mpeg1, too. or is it removed?

btw, what about mpeg4 support?

Oh, yes, mpeg1 too.

It would be nice I think, but for now this is only a remote dream :)

Why remote? I've looked at DivX sources - they support too few of 
MPEG-4. Primarily the internals are much the same as MPEG-2, except for 
more complicated Huffman decoder and post-processing (deblocking, 
smoothing, etc.) MC, IDCT, color conversion, and architecture may be 
reused. So IMHO we can add support for lower MPEG-4 natural video 
profiles...

Michael Niedermayer did a great job for mplayer, he implemented
postprocesisng stuff (and some more: deinterlacing and noise filters)
and optimized for mmx,sse,3dnow. All is GPL.
It can be used, so only the huffman thing have to be implemented by you.

As far as I understand, the two differ only by MPEG-4 standard 
compliance. The former is not compliant at all, and the latter claims to 
be H.263+. I may mistake, because I judge after a brief look through code.

Thanks, you left us the most interesting part ;-)
