Thanks to our flexible interface, Lead Encoding Engineer, Christian Feldmann, had already added the library interface to the open-sourced reference encoder (VTM) and also added a patch to our internal encoder, which pushes frames to the VTM encoder and retrieves any data from it. Now that the VVC codec parameters have been established we needed to actually implement them into the Bitmovin encoder. At the time of our test, VVenC and other encoder implementations, like x266 were not yet available and thus the settings are unknown. Any other specialized settings will depend on the encoder implementation that we use when live. These are colorConfig, sampleAspectRatio, encodingMode, preset, and profile. There are additional input values necessary for a real VVC encoding but didn’t apply for our test. For the first set of tests we used the following: width, height, bitrate, pixelFormat, rate, and Constant Rate Factor (CRF) as seen below: Since we haven’t established a “real” encoder yet, there are limited settings, parameters, and inputs that we can use. The first step to enable VVC encoding is to add VVC as a new video codec to our API. However, some critical changes were needed in the Bitmovin API to enable VVC encoding. To kick-off our experiment, we added the VVC Test Model (VTM) encoder library into our encoder with a flexible interface. The end goal of our research was to implement the VVC distribution process into Bitmovin’s standard encoding process, as illustrated below: “Overall, H.266/VVC provides efficient transmission and storage of all video resolutions from SD to HD up to 4K and 8K, while supporting high dynamic range video and omnidirectional 360° video.” – Fraunhofer HHI While Fraunhofer HHI claimed that the VVC codec promises to improve visual quality and reduce bitrate expenditure by around 50% over HEVC, we wanted to prove the validity of the statement. The ultimate goal of the project was to determine the performance parameters of the VVC codec and the subjective visual quality enhancements that ensue. As fellow members of MPEG, the Bitmovin encoding team was eager to test the capabilities of the newest codec and the potential improvements it offered over its predecessor h.265/HEVC. Versatile Video Coding (h.266/VVC) is the newest block-based hybrid codec from the Joint Video Experts Team (JVET), a group comprised of MPEG and ISO/ITU members such as Bitmovin and Fraunhofer HHI, and promises to vastly improve the compression capabilities of workflows for any organization within the streaming industry, including but not limited to, OTT, VR, AR, and many other providers.
Hevc codec vlc drivers#
Reinstalled latest GPU drivers with Driver Cleaner.VVC – the latest evolution for modern codecs Output - Opengl for windows, Direct3d9, DirectX(DirectDraw)ĭid the same with DXVA3 (d3d11 hardware decoding) That one shows the same : Stream 0 - Type : Video, Codec : MPEG-H Part2/HEVC (H.265) (hevc) I have another video that does not play video but only plays audio. Under codec information, it shows for Stream 0 - Type : Video, Codec : MPEG-H Part2/HEVC (H.265) (hevc) Hardware accelerated decoding = D3D11 Video Acceleration
The 2nd one is after I changed video settings to d3d11 through the method below. the first one is with default VLC settings. I have a Haswell-E i7 5930k 4.2ghz with 16GB DDR4 ram.
Hevc codec vlc windows 10#
My PC specs are GTX 1080Ti with latest nvidia drivers and am using the latest version of Windows 10 圆4. No video playback for HEVC videos but I am seeing a grey screen when playback starts and audio works just fine.
