MediaCoder 0.8.37 released with NVENC HEVC encoding bitrate control issue fixed (Stanley posted on August 31st, 2015 )
MediaCoder 0.8.37 is released. In this release, the NVENC encoding bitrate control issue in ABR and CQP rate mode, which has been reported by many users who use NVENC to encode H.265/HEVC, is finally fixed. Other updates include upgrade of x264 and x265. MPlayer and MEncoder for x64 have also been updated to latest SVN revision. From this release, MediaCoder is built with Microsoft Visual Studio 2015.
MediaCoder is finally able to encode with NVENC, NVIDIA’s hardware SIP core that performs H.264/AVC and H.265/HEVC video encoding. NVENC SDK 5.0.1 is used, so NVIDIA GPU driver 347.09 or above is required. The latest version of SDK has added support for HEVC (H.265) encoding on GM20x GPUs (GTX980 and future Quadro/Tesla/GRID platforms based on GM20x GPUs). Following is the description of NVENC from NVIDIA’s official website.
The NVIDIA Encoder (NVENC) API enables software developers to access the high-performance hardware H.264 and HEVC (H.265) video encoder in Kepler and Maxwell class NVIDIA GPUs (See list of supported GPUs below).NVENC provides high-quality video encoding that is faster and more power efficient in comparison to equivalent CUDA-based or CPU-based encoders. By using dedicated hardware for the video encoding task, the GPU CUDA cores and/or the CPU are available for other compute-intensive tasks. NVENC on GeForce hardware can support a maximum of 2 concurrent streams per system. NVENC for GRID, Tesla and certain Quadro GPUs (see below) can support as many streams as possible up to maximum NVENC encoder rate limit and available video memory.
To test NVENC with MediaCoder, please install the latest MediaCoder Full Edition and install the following update.
Once the update installed, NVENC will appear in the video encoder list. Disable video encoder auto selection and choose NVENC and MediaCoder will encode with NVENC. The supported video format is H.264 and H.265 (if you have a GeForce series 9 card). Currently the configuration tab for NVENC is not yet done as the support for NVENC is just initial and is still being worked on. To adjust its parameters, click the “Encoder” button. More parameters will be adjustable in future updates. Have fun with the cutting-edge breezing fast hardware encoding with 10-year old MediaCoder.
MediaCoder 0.8.32 released with multiple-pass H.265 encoding (Stanley posted on September 19th, 2014 )
In this release, 2-pass and 3-pass H.265 encoding have been added, and not many changes besides some routine update of codecs and minor bug fix. Anyway I know many people are demanding for the multiple-pass H.265 encoding. 😉
As always, head for the download page for the latest version.
It’s been a while since last update on the blog, though updates for MediaCoder are released from time to time. Thinking it might be good to know about where our users are from, I extracted some data from Google Analytics which can reflect the geographical distribution of active users of MediaCoder (not number of installations) in the past 3 months. Here comes the data.
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.
