Recently I’ve been spending some time improving MediaCoder’s support for Intel MSDK encoder, the GPU acclerated H.264 and MPEG-2 encoder from the chip giant. A new revision of MediaCoder (before I can finish and implement all the major improvements in my mind and release MediaCoder 2012), is released containing several improvements including slight performance boost when using Intel MSDK encoder to perform hardware accelerated encoding.
Actually the performance of Intel MSDK encoder is astonishing. This comes from the good implementation of the underlying multimedia facilities of Intel Media SDK framework, as well as the multi-threaded design of MediaCoder, espeically its built-in large circulla frame buffer used for efficiently transferring raw audio and video data from decoder to encoder.
Here I give some tips for using Intel MSDK encoder in MediaCoder.
