[ excerpt from developer's site ]

It is a free library for decoding mpeg-2 and mpeg-1 video
|
|
streams. 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 - for most current systems, the display will actually take
|
|
more time than the mpeg-2 decoding. For systems that have hardware
|
|
color conversion and scaling (as we can use with the xv extension
|
|
in Xfree 4), you should be able to watch DVD streams on a Celeron
|
|
400. On a PIII/666 with null display you should get about 110 frames
|
|
per second.
|
|
|
|
Portability - most of the code is written in C, and when we use
|
|
platform-specific optimizations we always have a generic C routine
|
|
to fall back on.
