What Intel Media SDK brings to MediaCoder (Stanley posted on February 20th, 2012 )

MediaCoder started to adopt Intel Media SDK in early 2010. By using the GPU accelerated encoder provided by the SDK, MediaCoder achieved significant increase in H.264 and MPEG-2 encoding speed, which reaches up to 5 times faster than encoding with x264 or FFmpeg. Being able to off load the heavy encoding computations to GPU, MediaCoder can better use the CPU to perform I/O operations, task management´╝îaudio decoding/encoding, stream multiplexing and most importantly video decoding which is also computational complex and obviously there are too many long-existing or legacy formats to have the GPU implementation for all of them. Comparing to nVidia's CUDA accelerated H.264 encoder, Intel's implementation provides much better visual quality, which makes the GPU accelerated video encoding acceptable by industrial customers, especially those of MediaCoder KTV Edition who perform massive transcoding for serious business use.
