MediaCoder’s Segmental Video Encoding (SVE) is now working with H.265/HEVC encoding. SVE is a unique techonology in MediaCoder designed to improve the parallelism of those encoders unable to consume 100% CPU power due to the lack of or non-optimal multi-threading implementation. By observation, x265, the H.265/HEVC encoder used in MediaCoder, is not utilizing 100% CPU power on a quad-core i7 processor. That’s when SVE becomes effective in boosting the encoding. Another importance of working SVE with H.265 is that it is the fundamental of future distributive encoding of H.265.

MediaCoder H.265 encoding is open for beta testing. For users who want to involve in the beta testing, please download the update package (both x86 and x64) and apply it on the installation of latest MediaCoder 0.8.28. If you haven’t installed MediaCoder or your MediaCoder is out-dated, please go here to download the latest MediaCoder full installer and install MediaCoder with it before applying the update.
I have been working on adding H.265 encoding support to MediaCoder. Today, everything finally gets to work. I encoded a sample video clip (H.265/HE-AAC-V2/MP4, 1280×720 @ 512Kbps). The visual quality is quite amazing. Right click the link (browser can’t play it), “Save As” to download it, and play with latest VLC.
I think this is going to happen as H.264/HEVC seems getting high these days, especially after a Chinese online video giant xunlei.com annoucing their adoption of H.265 in their kankan video streaming service. After some lookups, I found following implementations of HEVC encoder.
I will start evaluating all of these and see what can be done to add H.265 encoding in MediaCoder.
MPEG drafts twice-as-efficient H.265 video standard, sees use in phones as soon as 2013 (Stanley posted on August 17th, 2012 )
All of that squabbling over H.264 may be rendered moot in the near future. The Motion Picture Experts Group (better known as MPEG) has just let us know that it was quietly drafting a new video standard while everyone was onsummer vacation last month: H.265, also called High Efficiency Video Coding, promises to squeeze video sizes with double the efficiency of H.264. As you might imagine, this could lead either to a much smaller video footprint for bandwidth-starved mobile users or a hike to image quality with the same size as before. Imagine fast-loading HD streaming on 4G, or cable TV without all the excess compression, and you’ve got the idea. Ericsson Research visual technology lead Per Fröjdh anticipates H.265 coming as soon as 2013, when our smartphones and tablets are most likely to play it first. TV and other areas might have to wait, although Fröjdh is offering a consolation prize — he’s teasing a separate MPEG project that could give us glasses-free, compressed 3D video as a standard by 2014.
