Recently (actually since I posted an article introducing MediaCoder’s new CUDA support on the doom9 forum), a group of people, mainly those developing software similar to MediaCoder, began to pick holes in MediaCoder. Some of the same people, requested that the FFmepg group put MediaCoder on the FFmpeg shame list, accusing MediaCoder of abusing and modifying FFmpeg without publishing the patch. They also insinuated that MediaCoder contains virus and malwares, as well as tampering with the MediaCoder description on Wikipedia and changing the description as adware. I am very angry and shame on them. I hereby make the following statements:

MediaCoder is improving all the time even if the version number keep the same. This time there are some major changes, so let’s increase the number after nearly 10 months. I’ve spent lots of time to prepare the release of 0.7. Let me briefly recall what has been changed. Read the rest of this entry »

MediaCoder does not collect or submit any user information, even anonymously. The following statistic data is estimated from the percentage of visitors (data provided by 3rd party Google Analytics and Easy Counter) to the MediaCoder Full Pack download page at http://mediacoder.sourceforge.net/dlfull.htm. This indirectly reflects the current geographic distribution of users (assuming that most people don’t just visit the download page for fun).

Distribution by contintent:

Eastern Asia 24.0%
Northern America 18.8%
Western Europe 16.2%
Eastern Europe 12.1%
Southern Europe 10.1%
Northern Europe 6.3%
South America 5.9%
South-Eastern Asia 3.4%

Since 0.6.1.4135, MediaCoder has integrated the support for JM H.264 decoder and encoder. JM H.264 decoder is able to decode the H.264 streams generated by many HD camcorders correctly which other open-source H.264 decoders cannot. JM H.264 encoder is one of the three major open-source H.264 encoder implementations. It has very rich parameters and support most features of H.264. Some frequently used parameters have been added into MediaCoder while the rest of thundreds of paramters can be adjusted by loading a JM configuration file (by specifying the configuration file path at “Configuration File” option). A JM configuration file is a plain text file.

Recently MediaCoder has been equipped with a built-in media server, which is able to stream out media files with real-time transcoding.

What is this feature be used for? There lots of applications for a streaming server, especially one with capability to transcode while streaming. Here I list some typical applications:

• Watch video and listen to music from another PC or any capable device, through LAN/WLAN/Internet etc.
• With real-time transcoding, we can even play all kinds of contents on a less-capable networked device, e.g. PDA and mobile phone, regardless of the audio/video format of the original content and without having to convert its format.
• Preview encoding effects without performing a complete file-to-file transcoding.
