YouTube (Google) 允許環球唱片 (Universal Music Group,UMG) 直接移除非 UMG 所擁有版權的影片
依照環球唱片 (Universal Music Group,UMG) 提供給法院的文件中,YouTube (也就是 Google) 允許 UMG 透過 YouTube 的 CMS (Content Management System) 移除「不屬於 UMG 的影片」:「Google Deal Allegedly Lets UMG Wipe YouTube Videos It Doesn’t Own」,文件 (PDF) 在:「gov.uscourts.cand.248875.14.0.pdf」這邊可以下載取得。 重點在於這份文件中第四頁的這段: The UMG-YouTube agreement grants UMG rights to effect … Continue reading
YouTube 將 99% PV 影片加上 WebM 支援
YouTube 發了一篇公告,將站上約 30% 的影片另外壓一份 WebM 格式,而這 30% 佔全站 99% pageview:「Mmm mmm good – YouTube videos now served in WebM」。 目前在 Firefox 4+、Opera 10.6+、Google Chrome 支援 WebM 格式,手機平台則是 Android 2.3 (Gingerbread) 支援。 希望有一天可以完全取代 H.264…
在 Ubuntu 10.10 上看 RV10 影片的方式…
最大的問題在於 codec,所以講重點就好:裝 libavcodec-extra-52。不同 Ubuntu 版本後面的號碼可能不一樣,用 apt-cache search libavcodec 應該可以看到。 預設用 rv40 解,打開兩秒就停住,換上去以後就正常了…

Google 推出 VP8 的硬體設計
Google 推出了 VP8 編碼與解碼的硬體設計,代號「Anthill」:「Introducing “Anthill,” the First VP8 Hardware Encoder IP Release」。 透過 Anthill,對於 GPU 的 loading 及電源消耗會大幅降低:(這是在 ARM 平台上的估算) 不過比較奇怪的是只有寫 H1 encoder RTL 不收錢?重點在 decoder 吧? Google does not require payment of any license fee or royalty in connection … Continue reading
YouTube/Winny 有助於日本動畫的銷售?
在 Slashdot 上看到「Piracy Boosts Anime Sales, Says Japanese Government Study」,引用自 TorrentFreak 的「Internet Piracy Boosts Anime Sales, Study Concludes」。 原始的報告可以在「Do Illegal Copies of Movies Reduce the Revenue of Legal Products? The case of TV animation in Japan」(Abstract 是英文,報告本身是日文 PDF)。 作者分析 YouTube … Continue reading

2010 年的 BitTorrent Zeitgeist
在 12/27 就有網站先公佈了 2010 年的 BitTorrent Zeitgeist:「BitTorrent Zeitgeist: What People Searched For in 2010」。 「2010」名列前茅並不意外,倒是「inception」(全面啟動) 與「iron man 2」(鋼鐵人2) 這兩部作品居然這麼紅,可以直接幹掉「2010」 XD 另外那個「xxx」是怎樣 XDDD

BSD license 的 HDCP 加密、解密程式碼
在 Slashdot 上看到有人將 HDCP encryption/decryption 的程式寫出來了:「HDCP Encryption/Decryption Code Released」。 程式碼網站在「HDCP Encryption/Decryption Code」這裡,以 BSD license 釋出。為了加速加解密,也用上了 SSE2… 640×480 加密的部份,使用單核心在 Intel Xeon 5140 上可以跑到 181 frames/sec,而在 Core2 Duo P9600 上 (也是只使用單核心) 則可以跑到 76 frames/sec,看起來是 L2 cache 的大勝利… 解密的部份只有 1/7 的速度,但可以使用多核心平行化處理,所以在高階的 CPU 上 … Continue reading

H.264 的近況

YouTube 將提供 4096×3072 的影片格式給合作夥伴…
在 TechCrunch 上看到 YouTube 將提供 4096×3072 的影片格式讓合作夥伴上傳:「YouTube Announces Partner Grants Program, Support For 4K Video Resolution」。YouTube 的公告則是在「What’s bigger than 1080p? 4K video comes to YouTube」這篇。 YouTube 先把自己能做的部份做完,接下來只要有 source 就能上去。 接下來的困難在於,能拍攝 4096×3072 格式的設備不便宜,而且就算有 source,使用者也必須有超大的頻寬才看得動。但如果超高解析度會是潮流,YouTube 會先把位置卡死,不讓其他業者進入…

WebM 以及 VP8 將成為下一代影音標準
經過這半個月的發展,看起來 WebM 以及 VP8 會是下一代影音的新標準。 去年 Mozilla (Firefox) 及 Opera 因為 H.264 的軟體專利問題而不願意支援 H.264,所以大家都很注目比較可能沒有專利問題的 Theora。這是基於 On2 Technologies 在 2001 年所 open source 的 VP3 而發展出來的。也因此大家對於是否可以用 Theora 取代 H.264 一直很有疑問 (參考二月時寫的「Theora 與 H.264 的畫質差異」)。 首先是 Google 在 2009 年八月的時候買下 On2 Technologies … Continue reading
