| Summary : A free MPEG-2 video stream decoder
|
Description :
libmpeg2 is a free library for decoding mpeg-2 and mpeg-1 video streams.
It is released under the terms of the GPL license.
The main goals in libmpeg2 development are:
Conformance - libmpeg2 is able to decode all mpeg streams that conform
to certain restrictions: \"constrained parameters\" for mpeg-1, and \"main
profile\" for mpeg-2. In practice, this is what most people are using.
For streams that follow these restrictions, we believe libmpeg2 is 100%
conformant to the mpeg standards - and we have a pretty extensive test
suite to check this.
Speed - there has been huge efforts there, and we believe libmpeg2 is
the fastest library around for what it does. Please tell us if you find
a faster one ! With typical video streams as found on DVD\'s, and doing
only decoding with no display, you should be able to get about 110 fps
on a PIII/666, or 150 fps on an Athlon/950. This is less than 20 cycles
per output pixel. In a real player program, the display routines will
probably take as much time as the actual decoding !
Portability - most of the code is written in C, and when we use platform-
specific optimizations (typically assembly routines, currently used for
the motion compensation and the inverse cosine transform stages) we always
have a generic C routine to fall back on. This should be portable to all
architectures - at least we have heard reports from people running this
code on x86, ppc, sparc, arm and sh4. Assembly-optimized implementations
are available on x86 (MMX) and ppc (altivec) architectures. Ultrasparc
(VIS) is probably the next on the list - we\'ll see.
Reuseability - we do not want libmpeg2 to include any project-specific
code, but it should still include enough features to be used by very
diverse projects. We are only starting to get there - the best way to help
here is to give us some feedback !
