  • De l’upload à la vidéo finale [version standalone]

    31 janvier 2010, par

    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source
    Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".

  • HEVC : Fetching the input width and height from input bin stream

    1er juillet 2022, par Zax

    I have created an elementary bin stream using HM-12.0 reference code. So the out put is an HEVC encoded bin stream (say input.bin).

    



    I have a task which involves reading the header of this elementary stream. That is i need to fetch information such a the stream width, height etc. from the input.bin file.

    



    After seeing a lots of streams, i can conclude that all these bin streams starts from the sequence :

    



    00 00 00 01


    



    So whenever i see this sequence in any bin stream, i can say that this stream has to be decoded by HEVC decoder.

    



    Further if i want to fetch the width, height, fps etc. from the input.bin (like ff_raw_video_read_header function in ffmpeg), that are the steps need to be performed to fetch this information ?

    



    I have gone through the parsing section of the HEVC draft, but its very complicated for my level in video domain. Can anyone suggest a simple way to fetch the required information from the encoded bin file ?

    



    Any suggestions will be really helpful to me. Thanks in advance.

  • avcodec/ffv1enc : mark RGB48 support as non-experimental

    avcodec/ffv1enc : mark RGB48 support as non-experimental

    Resulting bitstream was tested with a conformance checker
    
using the last draft of FFV1 specifications.
    

    Signed-off-by : Michael Niedermayer <michael@niedermayer.cc>
    

    Also the files are already in the wild, and decoder support is
    
thus needed. And with decoders widely supporting it, there is no
    
advantage in not allowing it in the encoder.
    
The exact bitstream format may change in future versions of the
    
spec, if improvments are found.
