MediaCoder is no longer hosted on SourceForge.net from this day on

From this day, you will not be able to find MediaCoder on SourceForge.net. Through the years, MediaCoder was hosted on SF.net as an open-source project and through the years I was the only active maintainer of the project and have been spending time and efforts providing the community with the best free media transcoder. Many people praise for the work that I’ve done and many support me by making a donation. The only thing I’ve never got is a significative help on the development. Meanwhile, I was receiving some requests for explaining or modifying the code from some people who are quite likely working for some enterprises although they usually claimed they just wanted to “study” the code. When I made a decision that I no longer commit my new code to SF.net, it seems many people are infuriated. They spread words here and there about some disputable and untruthful facts. Under the pressure, I was opening the part of the source code of MediaCoder on SF.net again. But these people are still not satisfied as not getting every line of the source code and keep snitching. I kept contact with the senior manager of SF.net and I can see he was kept annoyed by those paranoias. Now the disturbance can come to an end by the removal from SF.net. I can once again concentrate on the development of MediaCoder without spending time and efforts to please those people.

Here I reaffirm, MediaCoder is and will always be a freeware and I have no plan to turn it into a commercial software in any time.

Also the formal web site of mediacoder.sourceforge.net no longer exists. The official web site of MediaCoder is www.mediacoderhq.com.

Now it’s easy to set processor affinity for decoder and encoder

In the build 4560, you can easily set processor affinity for audio/video decoder and encoder. By clicking the check boxes which represent each core of your processor. If you have a quad-core processor, you will se 4 check boxes enabled and selected by default. Unticking a checkbox will cause a core not to be used by chosen decoder or encoder.  If you processor has many cores, this will be useful, as you can allocate different cores for different use, or preserve some cores free for your other tasks. Some tips:

  • Even if all cores are selected, they are not necessarily be 100% utilized during transocidng. This depends on the multi-threading support in decoder or encoder.
  • A started job will not be affected by the change of the affinity option, unlike the change of the prioirty option.
