[Libmpeg2-announce] [ANN] libmpeg2 0.5.1

[Sam H. <sa...@zo...>]

   Hello,

   It was bound to happen: last week's unexpected yet acclaimed libmpeg2
0.5.0 release came with its own deal of new bugs. Fortunately, nothing
grave really happened, and the shiny new 0.5.1 solves all the problems
we are aware of.

   From the NEWS file:

This bugfix release fixes issues with the installation of headers and
pkgconfig files.

   For more information, please visit the libmpeg2 website at the
following address: <http://libmpeg2.sf.net/>. The new package can be
found here: <http://libmpeg2.sf.net/files/libmpeg2-0.5.1.tar.gz>.

Have fun,
-- 
Sam.

[Libmpeg2-announce] [ANN] libmpeg2 0.5.0

[Christophe M. <ma...@vi...>]

Hi folks,

We are glad to announce a new version of libmpeg2 and mpeg2dec. Sam 
and I would like to thank all contributors who have sent us patches 
with determination and patience, and who have truly made this release 
possible.

 From the NEWS file :

New optimizations have been provided for SSE2 and ARM instruction sets,
while a lot of warnings triggered by recent compiler changes have been
fixed.

A new function has been added to guess the aspect ratio of streams where
it is not properly coded. Also it is now possible to retrieve the value
of the MPEG-2 repeat_first_field flag, and to be notified when the
sequence header of a stream changes (eg. aspect ratio on-the-fly changes).

Enjoy!

[Libmpeg2-announce] Released libmpeg2 version 0.4.0

[Michel L. <wa...@zo...>]

From the NEWS file:

mpeg2dec-0.4.0 Tue Dec 23 03:04:35 PST 2003

Jeez, it's been way too long since the last release.

The big functionality that warrants a 0.4.x version number is that we
added support for 4:2:2 for 4:4:4 chroma formats. Thanks to Peter
Gubanov for starting the effort there.

A large part of the development effort has been to fix corner cases
that happen with bad or corrupted streams, concatenated streams,
etc... Regis Duchesne created test cases for this, which was a huge
help. Right now the situation is that we don't know how to make
libmpeg2 crash even when we try hard.

There is a new helper library for color conversion to common format
(currently rgb and uyvy). The ABI between libmpeg2 and libmpeg2convert
might change in the future, but source code compatibility will be
preserved. In the past people were supposed to write their own color
conversion routines which was a pain since the API was messy.

David S. Miller contributed some very nice sparc VIS optimizations for
the motion compensation. There are no VIS optimizations for the IDCT
yet but the plan is to get these in for a future 0.4.1 release.

New functions have been added to set the buffer stride and to reset
the decoder (typically after seeking thru a file).

There is some very basic documentation in doc/* - it's still quite
limited though. My good resolution for 2004 is to write better
documentation :) In the mean time feel free to ask on mpeg2dec-devel
or on irc.freenode.net channel #livid

The speed has not changed much since last release - we tend to be
about 1% faster. That's not too bad considering we have new features.
----- cut here -----

Going forward, the plan is to release 0.4.1 in january or february,
with at least some proper documentation and hopefully the sparc VIS
IDCT optimizations. Crossing my fingers, we'll see how it goes.

Happy holidays,

[Libmpeg2-announce] mpeg2dec 0.2.1 released

[Michel L. <wa...@zo...>]

After a long delay, mpeg2dec 0.2.1 has finally been released

Two major new features: First, a much higher tolerance to corrupted
streams. Instead of just segfaulting, we should now be able to keep
going after errors. There is no test suite for this feature yet though.

Second, the altivec optimizations provide a huge speedup (more than
2.5x) on ppc g4 machines.

High definition video streams are now supported.

There is also native support for compiling using VC++.

And, the libvo interface has been slightly extended so people can more
easily make use of the various mpeg flags.

This version keeps the same API as version 0.2.0, so it should be
quite easy to move forward. This will probably not be true in the
future though (there is a new API planned for version 0.3.0)

Cheers,

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