MLT: got cores?  
Monday, 22 February 2010
Building upon all the big new things for MLT in 2010, this week I started working on adding parallelism in the consumer base class. Previously, it only had one thread for decoding and processing separately from the derived consumer (e.g. FFmpeg encoding, SDL/SDI output). Considering, the producer/consumer and a frame object-as-unit-of-work design of MLT, this was one of those embarrassingly parallel situations. This screenshot shows my Core i7 8-core machine transcoding from HDV, scaling width from 1440 to 1920 with bilinear interpolation, deinterlacing with YADIF, and multi-threaded encoding back to MPEG-2.

This post aims to be read  
Thursday, 03 December 2009

The aim of this post is to point out there has been a definite, not-so-recent uptrend in writing to use the phrase "aims to" or "the aim ... is." This follows other trends of using "That said," preceded by a trend of "All in all" preceded by beginning most posts or lines of speech with the word "So." Don't 'cha know?


My Google Wave invite message  
Wednesday, 07 October 2009

I think that Google Wave looks fantastic, and I requested an invite with this message that you might find interesting:

I am an open source developer very active in the video editing space. I am interested in exploring how wave and its protocols can be used for collaborative video editing. I am thinking about not just professional usage, but casual sharing that naturally morphs into a more composed and published result. Imagine some family, club, sporting, or business event where afterward people share feedback and their media resources and then some continue on to participate in a mashup-like process to chronicle the event.


Open Video Conference  
Friday, 19 June 2009

Open Video Conference The Open Video Conference is happening now. My earlier post about Ogg Theora was intended to be somewhat objective about one corporate perspective regarding patents. In truth, I have been rather indifferent about Theora. However, with the adoption of Ogg Vorbis+Theora in HTML5 <video> implementations, the adoption by major sites, and the major improvements to the encoding library Thusnelda, I have become a fan. Also, I do have confidence that Fluendo and Red Hat legal consultations have vetted potential submarine patent issues.

Therefore, in this spirit, and in the spirit of the Open Video Conference, I am giving support for Ogg Theora a greater priority in MLT and therefore Kdenlive. In the releases thus far,  there was a major memory leak in the MLT avformat encoding plugin when encoding to Ogg Theora with Vorbis. This is now fixed, and the fix will become visible to most users in the Kdenlive 0.7.5 release. Next, I need to work on a new plugin to provide better support for Ogg source clips.
