  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • avcodec/libmp3lame : Avoid copying data, allow user-supplied buffer

    avcodec/libmp3lame : Avoid copying data, allow user-supplied buffer

    The libmp3lame encoder already uses an internal buffer, so that the
    
packet size is already known before allocating the packet ; therefore
    
one can avoid another (implicit) intermediate buffer by switching
    
to ff_get_encode_buffer(), thereby also supporting user-supplied
    
buffers.

  • -8969 error decoding h264 stream with intra-refresh

    28 décembre 2017, par ciclopez

    I’m trying to decode an h264 stream using video-toolbox, I create it with ffmpeg and it’s working nicely when I use this command :

    ffmpeg -y -f:v rawvideo -c:v rawvideo -s 1280x720 -pix_fmt bgra -r 30 -an -i - -pix_fmt yuv420p -c:v libx264 -tune zerolatency -preset fast -b:v 5M -refs 1 -g 30 -profile:v high -level 4.1 -f rtp rtp://192.168.1.100:5678

    however, when I enable intra-refresh

    -intra-refresh 1

    decoding fails with error code -8969 when VTDecompressionSessionDecodeFrame() is called.

    As you can see, I send the stream through the network using rtp, so I take care of processing UDP packets to extract NAL Units. I triple checked this process and discarded a problem with this part of the code.

    I didn’t find any info about Video-toolbox not supporting intra-refresh, so the question is, does Video-toolbox support intra-refresh ? and if it does, am I missing something in the ffmpeg side that makes the stream not supported by Video-toolbox ?
