  • WebM Decoding Improvements in Google Chrome 6

    10 septembre 2010, par noreply@blogger.com (John Luther)

    Google Chrome 6 for Windows, Mac and Linux was released last week. We want to congratulate the Chrome team and thank them for their contributions to the WebM project.

    Making the web faster is a core goal of Chrome, and we are happy to report that across a set of test clips Chrome 6 decodes VP8 video significantly faster than the developer version that was released at our launch in May. On single-core Intel machines the average improvement is about 20% ; on multicore processors it ranges from 15% (two cores) to 50% (four cores). If you want to try it for yourself, get Chrome 6 and then follow our instructions for playing WebM videos on Youtube.

    We’ve made further decoding speed gains in Chrome 7 dev channel, and are working on better video rendering to further improve the WebM user experience.

  • Usurper of FATE

    31 juillet 2010, par Multimedia Mike — FATE Server

    Mans sent a message to the FFmpeg-devel list today :

    A new FATE

    Mike’s FATE system has done a great job over the last few years. It
    is however beginning to prove inadequate in various ways :

    [various shortcomings already dissected at length on this very blog]

    To address the above-mentioned issues, I have been working on a
    replacement system which is now ready to be announced.

    Check it out : http://fate.ffmpeg.org/.

    Considering that he just obsoleted something I’ve poured a lot of time and energy into over the last 2.5 years, is my first reaction to this news supposed to be unbridled joy ? Hey, I’m already on record as stating that I wouldn’t mind throwing away all of FATE if there was a better alternative.

    I’m not certain but I’m pretty sure that at this point, the original FATE server is practically obsolete. Mans is already testing all of his configurations as well as the configs I test. As soon as the other FATE installations switch over to the new server, I should be able to redirect fate.multimedia.cx -> fate.ffmpeg.org, sell most of my computers, and spend more time with my family.

    Thanks, Mans !

  • Where can I find modern tutorials for libav, ffmpeg, etc ? [on hold]

    19 décembre 2016, par Marty

    I want to make a quick program in C that will open a video, save each frame as a ppm, and dump motion vectors. All the tutorials I can find are from almost ten years ago and call deprecated or non-existent functions.

    Are there any good online resources, websites, videos, or textbooks that cover a modern approach to doing these types of things ?
