One of the significant improvements in MediaCoder 2011 RC is that Intel Media SDK Encoder is first time added to MediaCoder as an alternative accelerated H.264 encoder in addition to previous nVidia CUDA encoder. Intel’s encoder is hardware accelerated on Intel G45 and later platforms. It encodes H.264 as well as MPEG-2 off-loaded to GPU.  Benchmarks are welcomed for encoding with Intel’s encoder working in MediaCoder. For more changes, please refer to the changelog.

MediaCoder Dropbox is a simplistic user interface of MediaCoder which can be used to convert media files for a specific purpose so easily and conveniently. The appearance and transcoding parameters of a MediaCoder dropbox are defined by an XML file which can be on local disk, on remote server or embedded in any web pages. With this mechansim, users can create, publish and share their specific transcoder. Using MediaCoder dropbox is even easier. Simply load a dropbox whether local or remote, and drop media files into it and you can start transcoding. Read the rest of this entry »

Recently x264 has added 10-bit depth encoding and MediaCoder is keeping up with this new feature. In latest build 4777, new options of x264 have been added, including the High10 profile and 10-bit encoding. With 10-bit depth, video quality can be better at the same bitrate than encoding with common 8-bit depth. However, not all players/decoders support 10-bit depth. As far as I know, VLC can handle 10-bit depth.

Besides, MediaCoder is able to feed frames to encoders in color space of I422, YUY2 and RGB as well as common I420/YV12.

MediaCoder build 4755 has added two audio volume related features:

• ReplayGain calculation
• Volume normalization with pre-calculated ReplayGain value in 2-pass mode
