  • WebM Semantic Video Demo

    18 août 2010, par noreply@blogger.com (John Luther)

    Brett Gaylor at WebMadeMovies has posted an HTML5 demo of popcorn.js, “a javascript library for manipulating open video on the web.” The demo plays a video while using semantic data in the video to trigger machine-translated subtitles, map lookups, Twitter feeds and other elements on the page. If you’re using a WebM-enabled browser the page serves a WebM video, otherwise it serves an Ogg or MP4 video depending on the browser’s capabilities.

    See Brett’s post or the popcorn.js wiki page for more info. You can also download the source from the Mozilla github repo.

  • H.264 is patented. What happens when developing a commercial app in Android using H264 codec in ffmpeg ? [closed]

    26 mai 2013, par user1914692

    H.264 is patented.

    In countries where patents on software algorithms are upheld, vendors
    and commercial users of products that use H.264/AVC are expected to
    pay patent licensing royalties for the patented technology[14] that
    their products use.

    What happens when developing a commercial app in Android using H264 codec in ffmpeg ?

    Here there are two situations :
    (1) decode online video stream, and display it.

    (2) encode contents to a video file using H.264.

    [Update :]
    From what I googled, here are some simple pieces of information :
    (1) decode : free
    (2) encode : H.264 encoded internet video that is free to end users will never be charged royalties.
    On August 26, 2010 MPEG LA announced that H.264 encoded internet video that is free to end users will never be charged royalties. See Wiki H.264
    (3) encode : for other situations except the one in (2), I guess it might be for commercial use.

  • ffmpeg, HLS options, ffmpeg components for dummies ? [closed]

    10 juin 2013, par Vetal

    I am trying to make some HLS encoding with ffmpeg

    After playing a lot (in Ubuntu 12.04) with ffmpeg I realized I do not understand basic questions.

    How to make a ffmpeg "by the book" ?

    I've started a "sudo apt-get install ffmpeg"

    I finished with a manual install :

    http://ffmpeg.org/trac/ffmpeg/wiki/How%20to%20quickly%20compile%20FFmpeg%20with%20libx264%20%28x264,%20H.264%29

    Latter needed a following command to get rid of build error, where I spent quite some time with :

    sudo apt-get remove ffmpeg x264 libx264-dev

    So, now I've got to the documentation for HLS : http://ffmpeg.org/ffmpeg-all.html#hls-2

    Trying to run some stuff :

    ffmpeg -i 3.mp4 hls.m3u8

    Error : Unable to find a suitable output format for 'hls.m3u8'

    ffmpeg -i 3.mp4 -hls_time 10 hls.m3u8

    Error :
    Unrecognized option 'hls_time'
    Failed to set value '10' for option 'hls_time'

    Anyway, looks like an options specified in different formats, e.g. 'vbsf' vs 'v:bsf', -vcodec and -v:c, etc. etc. Like there are few alternative versions

    After starting with it some time ago, I feel more pessimistic now like I missed some fundametals. Any Ideas for the things above ?

    Thank you
