Dirac is a general-purpose video codec aimed at resolutions from QCIF (176×144) to HDTV (1920×1080), progressive or interlaced. It uses wavelets, motion compensation, and arithmetic coding, and aims to be competitive with other state-of-the-art codecs. The Open Source implementation provides a C++ library with an encoder and decoder.
MediaCoder 0.6.0.3690 has included Dirac video encoder 0.7.0.
MediaCoder’s preferences window has been reworked with XUL which provides a more friendly browser-based user interface. This demonstrates the possibilities of XUL which will be used to implement the user interface of MediaCoder in the future.
An experimental Apple TV extension was added in build 3678. As I don’t have an Apple TV on hand, no testing can be done. The parameters are coded with the spec available on the Internet. So feedback needed.
In the same build, the iPod extension was rewritte to provide more adjustable options.
Sometimes we need to encode with VFW codecs (mainly closed-source codecs which only comes in the form of VFW codecs). A scratch VFW encoder backend has been added to MediaCoder. To encode with VFW codecs, follow these steps:
Please note that encoding with VFW in MediaCoder is just AS-IS and may not work at all with some codecs. So don’t complain. 😉

You may need to set resolution, frame rate and resample options to make it work. If you are upgrading from previous builds, be sure to download and update the full pack if you need join mode work for audio-only transcoding.
