CHROME是支持DXVA..
他使用ANGLE的OpenGL renderer.. (Firefox也是使用ANGLE) 在windows上會轉換呼叫DXGI(D3D11) API去調用DXVA... (這是ANGLE API允許的作法..) 可以透過DXVA checker的log去觀察D3D11的初始化操作..... 但不好說這視訊串流(HTML5)上效率是不是跟原生edge差不多... 也有撥放器像是Qt使用這款API.. 不過表現出來的效果我覺得很爛...

從以前到現在 IE和EDGE都明顯好過火狐和CHROME 直接就能上去硬解 但火狐和CHROME還會失效或者根本沒硬解 只要遇到火狐和CHROME這兩個跑很差的影片 到IE和EDGE上就生龍活虎有該有的硬解效能出來 |

儘管有人狂推vpx 可惜始終是不成氣候…
當然這問題不是無解 各家公司坐下來搓圓仔 共推一個開放的影音編碼格式 Alliance for Open Media Open. Fast. Royalty-free. We are industry leading companies focused on developing next-generation media codecs, formats and technologies in the public interest. Launched in 2015, the Alliance for Open Media is a Joint Development Foundation project formed to define and develop media codecs, media formats, and related technologies to address marketplace demand for an open standard for video compression and delivery over the web. The Alliance’s initial focus is to deliver a next-generation video format that is: Interoperable and open; Optimized for the Internet; Scalable to any modern device at any bandwidth; Designed with a low computational footprint and optimized for hardware; Capable of consistent, highest-quality, real-time video delivery; and Flexible for both commercial and non-commercial content, including user-generated content. Among the Alliance’s goals is the creation of a new, high-quality open video codec that improves core media experiences for all. The JDF is an independent non-profit organization that provides the corporate and legal infrastructure to enable groups to establish and operate standards and source code development collaborations. wiki The founding members are Amazon, Cisco, Google, Intel Corporation, Microsoft, Mozilla, and Netflix.[1][2] The project will release new video codecs as free software under the BSD 2-Clause License and will use elements from Daala, Thor, and VP10.[4] AOMedia is planning for the first version of its format (AV1) to be completed by March 2017.[11] AOM(AV1)有足夠的分量同HEVC叫陣對抗 |

雖然vp8/9的一部分功能在經過增強後 與同業協商下
將會納入AV1(暫稱)的格式內 但不能掩飾其本身有如砲灰般的存在… |

請教
目前用G4560的內顯 播不順HEVC 4K 10Bit HDR的影片 流量78M的 由於記憶體只分1G給內顯 是否為VRAM不足? |

還記得以前最早看1080p藍光 是在1024*768的小螢幕上看的 當時就覺得藍光好讚 比DVD好太多 現在用FHD螢幕 是否也能看出 UHD比FHD更好? |
