Today MediaCoder has been tested with Intel Concurrency Checker, as was invited by Intel Software Partner Program. According to the reports sent back by Intel, the Computed Scaling value of MediaCoder is 2.6 and 3.71 for without and with task parallelization respectively, which reaches and surpasses the suggested minimum value for 8-core processors.

• Report 1 – Task parallelization disabled (default)
• Report 2 – Task parallelization enabled (2 tasks)

Some H.264 stream in MKV container is already iPhone or iPad playable. In such case, we only need to convert the audio format and remux the video stream with converted audio stream into MP4 container in order to let iPhone or iPad play it. This can save us significant amount of time for transcoding.

In addition to the iPhone 4 support, this new version also supports parallelized transcoding as well as all the other new features and fix-ups in the MediaCoder 0.7.5.

Get it now!

Since 0.7.5.4710, MediaCoder has added support for video capture device as a transcoding task. In other word, the video from a webcam or other DirectShow capture device can be encoded directly in MediaCoder now. You can see a new “Add Capture Device” when clicking Add button.

Finally we can have multiple files processed simultaneously in MediaCoder with the new job-level parallelization support. Those who have a processor with 8 or 16 cores can now unleash the power of their processor. As MediaCoder is not just a simple GUI front-end which only invokes a command line encoder wait sits there waiting for the encoder to complete, instead it distribute frame data and the audio samples from decoders to encoders, the job-level parallelization is not that easy to add from the old design. In order to add this feature, large amount of the code has been rewritten. Finally it works after several weeks’ efforts, though it might still be experimental for a while. The number of the maximum parallelized jobs is limited to 4 at the moment. So feedbacks welcomed!

We can use Debugmode Frameserver to easily connect Premiere (and some other NLE software) and MediaCoder 0.7.3.4682 (or later version). Video exported from Premiere can be encoded directly with MediaCoder to save time and effort and improving quality.

The following are the brief steps to make it work.

Installing DebugMode Frameserver

You can choose the plugins for the NLE software you are using. In my case, I use Adobe Premiere. Read the rest of this entry »

Quoted from the blog of an x264 developer:

For many years it has been possible to make your own DVDs with free software tools. Over the course of the past decade, DVD creation evolved from the exclusive domain of the media publishing companies to something basically anyone could do on their home computer.

But Blu-ray has yet to get that treatment. Despite the “format war” between Blu-ray and HD DVD ending over two years ago, free software has lagged behind. “Professional” tools for Blu-ray video encoding can cost as much as $100,000 and are often utter garbage. Here are two actual screenshots from real Blu-rays: I wish I was making this up.

But today, things change. Today we take the first step towards a free software Blu-ray creation toolkit.
