Using the right decoder for your video content
Dec/090
One thing that appears obvious to us after more than 10 years of working with the various solutions that can be used on Mac and Windows to decompress video is that not all solutions are equal.
We believe that our users should be able to play almost any kind of media with the ArKaos software and at the same time we do everything a team of developer can to get the best performance on the platforms supported.
Practically the ArKaos software can play media files through the following decoders: QuickTime, FFmpeg, the Flash plugin, Quartz Composer and Windows Media Player. Currently (December 2009) we don’t allow the user to decide through which solution a media will be decoded, instead we try to make the best decision based on our many years of experience and tests. In the case where several video codecs (such as Mpeg4) can be played through different decoders like QuickTime, FFmpeg and Windows Media Player, we always prefer, no matter the platform, to first try to handle those codecs with FFmpeg as we have always had the best results with FFmpeg during our tests, and here’s why..
New video codec based on texture compression
Jul/091
When it comes to media playback, at ArKaos we always fight to get the best out of current computer configuration.
When you are in the show industry and try to find out the best way to compress your content it’s still a little bit of black magic. While some codec are able to compress video very well they are heavy to handle for the machines, even more, the codec that does the best job at compressing while keeping a good quality such as H264 are very bad when you need to scratch your media.
The best codec for users that need to interact a lot with the content should allow to play forward and backward easily and should allow to jump into the content quickly.
Recently, I’ve heard about experiments with a file format designed by graphic card manufacturers and based on texture compression DXT1 DXT3 or DXT5 and I was wondering how hard it would be to add support for such a format to QuickTime through a new codec. Being programing for the QuickTime API since it’s version 1.0 beta I was considering the challenge fun and interesting.
