  • avformat/matroskadec : Support ContentCompression for all codecs

    6 décembre 2019, par Andreas Rheinhardt
    avformat/matroskadec : Support ContentCompression for all codecs

    The Matroska demuxer has three functions for creating packets out of
    
the data read : One for certain RealAudio codecs (ATRAC3, cook, sipr,
    
RealAudio 28.8), one for WebVTT (actually, the WebM flavour of it) and
    
one for all the others. Only the last function supported Matroska's
    
ContentCompression (e.g. it reversed zlib compression or added the
    
removed headers to the packets). But in Matroska, all tracks are allowed
    
to be compressed. This commit adds support for this.

  • Streaming video from nodejs to an open player

    27 août 2013, par Matthew Young

    Odd ball question for somebody just getting started with html5 players and streaming video....

    When using YouTube long videos can be scrolled towards then end then played from there. Assuming YouTube first pulls down metadata like total video start/stop points and a bunch of thumbnails for scrolling.

    Is this possible with an open html5 video player (like projekkter) ? Reason asking is that I have video data inside a mongo database that I would like to stream similar to the YouTube player.

    Inside mongo I have a bunch of smaller h264 files each in a document : actual raw h264 usually 1000kb (max 2 seconds), creation timestamp (long), and potentially a converted format (like mp4) for known clients. Idea is to query off a time range and order by creation time then piping the results into readable stream. There is a nice ffmpeg module to take streams and reformat if needed. Thought about piping the stream to the client with binaryjs and appending it into the player.

    But the source directives in the documentation are usually URLs plus I need to lock down the start/stop point for the total video being played plus thumbnails.

  • avcodec/rl : Don't pretend ff_rl_init() initializes a RLTable twice

    8 mai 2021, par Andreas Rheinhardt
    avcodec/rl : Don't pretend ff_rl_init() initializes a RLTable twice

    It can't any longer, because all users of ff_rl_init() are now
    
behind ff_thread_once() or the global codec lock. Therefore
    
the check for whether the RLTable is already initialized can be removed ;
    
as can the stack buffers that existed to make sure that nothing is ever
    
set to a value different from its final value.
    
Similarly, it is not necessary to check whether the VLCs associated
    
with the RLTable are already initialized (they aren't).
