    webmdashenc : Support for live stream manifests
    

    This patch adds support for creating DASH manifests for WebM Live
    Streams. It also updates the documentation and adds a fate test to
    verify the behavior of the new muxer flag.

  • Streaming WebM files on unsupported browsers (Safari, IE, etc)

    14 juillet 2015, par Swaathi K

    I’d like to stream WebM videos to browsers that don’t support it (like Safari/IE). I have no problem in converting the video to a supportable format (like MP4), but the encoding should be on-demand, that is, the server should stream the MP4 content while it’s being converted from Web (WebM -> MP4). I’ve seen a few solutions like Dash and Stream-M, but all these seem to do it the other way around (MP4 -> WebM). Is there a solution that already exists for my problem ? Or do I need to build my own hack ? And also is this solution the only way to stream WebM content onto Safari/IE ?

  • Adaptive video encoding with alpha channel

    14 septembre 2020, par Peter Bartha

    I've created a WebM media file with transparent background in Adobe After Effects. Due to Widevine specs, I have to encode this file to an adaptive format for playing.

    &#xA;

    With the following command I've successfully created a webm file with DASH :

    &#xA;

    ffmpeg -i example.webm -c:v libvpx-vp9 -s 200x113 -b:v 250k -keyint_min 150 -g 150 -tile-columns 4 -frame-parallel 1 -an -f webm -dash 1 adaptive.webm&#xA;

    &#xA;

    Unfortunately, the resulting video has lost the alpha channel completely.

    &#xA;

    Is it possible to encode a video to an adaptive format without losing the alpha channel ?
