  • Encoding and processing into web-friendly formats

    13 avril 2011, par

    MediaSPIP automatically converts uploaded files to internet-compatible formats.
    Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
    Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
    Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
    All uploaded files are stored online in their original format, so you can (...)

    avdevice/decklink_dec : add support for decoding teletext from 10bit ancillary data

    This also add supports for 4K DeckLink cards because they always output the
    
ancillary data in 10-bit.
    

    v2 :

    - only try teletext decoding for 576i PAL mode

    - some comments as requested by Aaron Levinson

  • Possible to copy PCR/PTS/DTS data between TS files ?

    19 avril 2024, par muraliv

    I've 2 h264/aac stream TS files (say a.ts and b.ts) that have same duration and packet numbers. However PCR/PTS/DTS data of their audio/video stream packets are different. How do I copy PCR/PTS/DTS data from a.ts to b.ts using ffmpeg or other tools without actually overwriting the audio and video frames data ? Ideally want to do this without re-encoding.

  • Generate FFMPEG Waveform Data

    30 septembre 2015, par samchoi

    Given a video file (e.g. test.mkv), is it possible to output the data points used to create a waveform using ffmpeg (or any other tool) ?

    I’m looking to create a file that maps audio level to time, so that I can parse the data. Most of the examples I am finding, output an image.

    The closest I’ve gotten is generating raw binary data with :
    ffmpeg -i test.mkv -ac 1 -filter:a aresample=8000 -map 0:a -c:a pcm_s16le -f data -
