SUMMARY="A library for decoding MPEG-2 and MPEG-1 video"
|
|
DESCRIPTION="libmpeg2 is a library for decoding MPEG-2 and MPEG-1 video. Its \
|
|
main development goals 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.
|
|
- Speed: With typical video streams as found on DVD's, and doing only decoding \
|
|
with no display, you should be able to get 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.
|
|
- Reuseability: libmpeg2 doesn't include any project-specific code, but it \
|
|
should still include enough features to be used by very diverse projects."
