Wine is an open Source implementation of the Windows API on top of X, OpenGL, and Unix/Linux. MediaCoder, as a native Windows application, was able to run under Wine in many cases. Before a native Linux version of the software is developed, the Wine compatibility is improved in build 4180. Now MediaCoder can run more flawlessly on Linux platform. It is no longer necessary to install a Windows version of Firefox under Wine as MediaCoder will look for native Linux Firefox in the Linux system and invoke it to display the XUL-based user interfaces when needed.

The test environment is Gentoo Linux / Xorg / XFCE4 / Wine 1.1. There are known issues under Darwine / Mac OS which might be fixed later. If you still encounter problems under Wine, please report.

Dirac video encoding has been fixed in 0.6.1.4140. In the past, Dirac encoding was done by calling Dirac encoder DLL. Now it is done by FFmpeg, which allows the encoded bitstream to be muxed into a container format together with audio stream. Dirac decoding and playback is also supported by building Schrodinger into MPlayer and MEncoder.

The x264 profile option changes to the encoder settings to let the encoded bit stream comforted to specified H.264 profile (baseline, main, high).

MediaCoder (build 3999) can now encode with the Enhanced 3GPP AAC+ encoder again. The encoder is updated (with the latest 3GPP AAC+ encoder reference code) and patched with some minor optimizations and AAC/ADTS container support by me. The Enhanced 3GPP AAC+ encoder is able to produce low-bitrate (16kbps to 48kbps) AAC+ with Parametric Stereo optionally.

The 0.6.0.3999 update contains the encoder. The x64 update contains the 64-bit version of the encoder which has an approximate 30% speedup than the 32-bit version.

In 0.6.0.3980, frames being encoded can be viewed. The frame is rendered with SDL at a specified interval so it won’t slow down the encoding speed noticeably and can be switched on/off instantly.

Please note that in some combinations (when video source is “default”, in this case, frames are not passing through MediaCoder), this feature won’t work.

In this build, several serious bugs have been fixed. For details please check the changelog.

As many users complained about, sometimes after a long time of transcoding was done, an error occurred because of a muxer error and this wasted their time.

So in 0.6.0.3940, an automatic testing phase was added before the actual transcoding starts. The testing phase will convert 1 second (can be altered at Settings->Overall->Task->Testing phase duration) of original content to see if the result file can be successfully created. Only on success, the whole file will be processed.

By default, the testing phase will be activated only when external muxer is to be used.

PMP MOD MOD AVC/AAC (aka PMP MOD Advance) has been added in the latest MediaCoder PSP Edition. The legacy PMP MOD XviD support has been restored as well. The PMP MOD XviD muxer is shipped with PSP edition but not with the full edition.

The benchmarking feature for transcoding is added. The information will be displayed after the transcoding of a file completes in the Properties side bar.
