2010-05-17: Time for another release, 2.5.3, as usual mainly done by Gruntster.

* Fixed again partial filter

* Added support for I420 video decoding

* H.263 video encoder now supports more profiles

* mpeg2enc video encoder no longer drops first few frames and now works on Win32

* The majority of video encoders are now plugins

* Updated the FFmpeg libraries

* Updated libass

* Avsproxy now supports audio

* All auto wizards are now scripted and available in both interfaces

* Needed files to compile your own plugins on windows (the *sdk*.zip file)

* Various minor fixes and enhancements

I would also like to thank the nice people giving time on the forum and wiki (JM, Lord Mulder, DarkZell, Agent_007,...).

On other news, the 2.6 version is progressing nicely. It is at the moment mainly tested as a way to convert DVB capture (SD and HD) to mkv, with no additionnal tool needed and with a correct a/v sync. For HD stream, you will want a VDPAU capable card.

2009-12-21: And here comes 2.5.2, the Christmas Avidemux release.

As usual for the 2.5 branch, most of the work was done by Gruntster.

2009-08-16: And here goes 2.5.1, a bugfix version.

There are still some restrictions regarding mpeg1/2 encoding, but

it should be now really close to 2.4.4.

* Re-enabled several video and audio encoders (regression introduced in 2.5.0)

* Updated the FFmpeg libraries

* More video encoders are now plugins

* DV video encoder now supports more profiles

* Fixed loading and saving issues with LAME, x264 and Xvid options (regression introduced in 2.5.0)

* Removed support for libamrnb and replaced with opencore-amrnb

* Removed support for libdca and replaced with libavcodec's DCA decoder

* AMR-WB audio decoding support using opencore-amrwb

* Fraps video decoding support

* Lowpass-5 mode added to libavcodec deinterlacer filter plugin

* Fixed formatting of parameters for various filters on 64-bit platforms

* Updated libass

* Fixed sizing of the bitrate control on various video encoder configure windows (regression introduced in 2.5.0)

* Improved filter dialog for GTK+ interface

* New navigation icons for GTK+ interface

* Fixed the behaviour of several GTK+ open/save dialogs (regression introduced in 2.5.0)

* asharp filter's Block Adaptive mode can now be disabled using the Qt interface

* Re-enabled the colour chooser dialog using the Qt interface (regression introduced in 2.5.0)

* GCC 4.4 support

* Fixed issues with CMake build scripts when using multiple make jobs (regression introduced in 2.5.0)

For linux users, use the handy bootStrap.sh to build it, it is way easier.

2009-08-01: Lots of fixes are going on with 2.5.0, it is probably better to use svn if you can.

On another note, the bugtracker is now down. It was unattended and thus inefficient.

Sorry for those who took the time to fill bug reports.

The official way is now to use the forum

2009-06-27: 2.5.0

And finally the first 2.5.x version. A note of warning, the build is done in two steps : Build the application(s), and then build the plugins.

There is some preliminary documentation in the wiki, be sure to have a look.

The changelog :

* Audio Codecs, Audio Devices and Video Filters are now plugins

* x264 and Xvid encoders are now also plugins with an updated Qt interface

* Auto wizards are now scripted and easier to extend

* Updated the FFmpeg libraries

* Various minor fixes and enhancements

2009-02-08: 2.4.4

Again, for those building it from source, please use cmake. The Autoconf/automake build is less tested and will be obsoleted very soon.

Another release, mainly done by gruntster (again)

* Fixed crash when opening some MOV files (regression introduced in 2.4.3)

* Improved support for H.264 in MPEG-TS and M2TS containers.

* Improved support for H.264 in MP4 container (including constant frame rate fix)

* Fixed bug where muxers could drop the first few B-frames (most containers were affected)

* Fixed FAAC support so bitrate is correctly honoured

* The same settings are now used for the first and second pass of an x264 encode

* Improved JPEG file support

* Improved PNG decoding (now uses libavcodec rather than a custom wrapper around libpng)

* Improved BMP/DIB decoding (now uses libavcodec rather than using own decoder)

* Improved colourspace handling for raw video, bitmaps and DIBs

* Fixed Previous Black Frame functionality

* Qt interface has been significantly upgraded and now fully functional (compared with its GTK counterpart)

* Saving of video is now prevented if the A marker is greater than the B marker

* Improvements made to ECMAscript including a new GetFilePath() function for the DirectorySearch class and fixes to the exec() function

* Add support for AAC audio to the command line interface

* Qt interface is now the default interface for MS Windows

* x264 and Xvid stat files with Unicode characters are now handled on MS Windows

* The application log file is no longer buffered on MS Windows to ensure sequential logging

* Added support for ppc64 to the CMake build scripts

* Updated the following translations: Catalan, Czech, French, Italian, Russian, Spanish

This will probably be the last version from the 2.4 branch. The next targets are 2.5 and 2.6.

The 2.5 branch is a big clean-up and modularization work from the 2.4 codebase.

A lot of things are plugins in 2.5, that will enable easier maintenance and cleaner code.

The 2.5 branch is in good shape and is really close to 2.4 as far as features and stability are concerned.

The next release will be a 2.5 one, and it will live most of 2009 probably.

The 2.6 branch is a long terme overhaul of the code. Meaning, switching from a frame based, constant frame rate model to a time based.

That will solve all the a/v sync issues encountered with variable frame rate format (mpeg, flv ....). Dont hold your breath, it wont

be ready anytime soon.

2008-07-24: 2.4.3

For those building it from source, please use cmake. The Autoconf/automake build is less tested and will be obsoleted very soon.
