Sam Dutton, developer advocate @Google for everything WebRTC (and then some), wrote a useful piece on how to use VP9 with Chrome 48. A few things interesting here: Chrome 48 now supports both VP8 and VP9 video codecs; While VP9 is the superior codec, it is NOT the preferred codec by default

Sample raw YUV files can be found at the following locations: These commands will put the encoded output into bear.mp4 and crowd.mp4 This document details some of the encoder controls that are available in VP8. Different encoders or tools will map these controls in different ways, but knowing what is available should at least give you some idea of what to look for. In this document we use the parameter names defined in the sample encoder, vpxenc.exe. A summary of the command

    5/12/2015В В· @Trules: if you can upload a sample wit 24bit sampling somewhere and send me a link I can look into it. Main problem is, I need to check how to configure the decoders to feed flac properly which is why I need a real 24bit audio sample. Most of the current VP9 decoders use tile-based, multi-threaded decoding. In order for the decoders to take advantage of multiple cores, the encoder must set tile-columns and frame-parallel. Setting auto-alt-ref and lag-in-frames >= 12 will turn on VP9's alt-ref frames, a VP9 feature that enhances quality.

    Sample commands to generate multi-bitrate content¶. Let us say we have a 1080p original content original.mp4 containing an audio track in AAC and a video track in H264.The frame rate is 24. We want to encode the contents into four resolutions: 360p, 480p, 720p and 1080p with GOP size 72, i.e. 3 seconds. 5/21/2018 · If Command Extensions are enabled, MKDIR changes as follows: MKDIR creates any intermediate directories in the path, if needed.

    VP9 is a next-generation video compression format developed by the WebM Project. The codec is open source and royalty free. VP9 supports the full range of web and mobile use cases from low bitrate compression to high-quality ultra-HD, with additional support for 10/12-bit encoding and HDR. VP9 can also reduce data usage for users with poor connections or expensive data plans, requiring in best cases only 40% of the bitrate of VP8. You can see how VP8 calls compare with VP9 in the screenshot below of recordings we made with the WebRTC …
