    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 (...)

  • 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 (...)

  • Fluent FFMPEG complex filter to split file into multiple outputs

    26 octobre 2020, par lowcrawler

    It appears possible to have multiple outputs from a single FFMPEG command : ffmpeg overlay on multiple outputs

    


    I'd like to know how to do this in FFMPEG. I'm specifically using the complexFilter option in an attempt to split the video into 4 different sizes and place an overlay, and then save the 4 resulting files.

    


    The code is my attempt to simply split the video into 4 and save it. I get the Error: ffmpeg exited with code 1: Filter split:output3 has an unconnected output error. I'm unsure how to connect the output to a file in fluent-ffmpeg.

    


        let ffmpegCommand = ffmpeg() 
        .addInput(path.join(__dirname, PROCESSING_CACHE_DIRECTORY, "tempImage_%d.jpg"))

        .addOutput(outputPathFull)
        .addOutput(outputPathMed)
        .addOutput(outputPathSmall)
        .addOutput(outputPathThumb)


        .toFormat('mp4')
        .videoCodec('libx264')
        .outputOptions('-pix_fmt yuv420p')
        .complexFilter([
        {
                filter: 'split', options: '4',
                inputs: ['0:v'], outputs: [outputPathFull, outputPathMed, outputPathSmall, outputPathThumb]
            },
        ])


    


    When I flip the outputs and put them below the complexFilter, I get 4 files - one with the appropriate quality (and 4x bigger than expected) and the others in very low quality.

    


  • Revision a5062cc635 : Don't call encode_sb() for the final of 4-split subpartitions. The resulting re

    8 juillet 2013, par Ronald S. Bultje

    Changed Paths :
     Modify /vp9/encoder/vp9_encodeframe.c



    Don't call encode_sb() for the final of 4-split subpartitions.

    The resulting reconstruction is never used, thus it just wastes CPU
    cycles. Reduces encode time of first 50 frames of bus (speed 0) @
    1500kbps from 2min2.0 to 2min1.2, i.e. a 0.65% overall speedup.

  • FFmpeg.AutoGen example of how to split audio file

    7 mars 2018, par Sven

    I want to use the FFmpeg.AutoGen project from here : https://github.com/Ruslan-B/FFmpeg.AutoGen

    I’m not familiar with the ffmpeg API, so I wanted to get an example of how to split an audio file into little files, for example the audio file is about 2 hours long (can be mp3,ogg,wav,etc.) and I want to split it into several little files of x minutes. The splitting should be done on the main audio file with timestamps from and to, for example from = 00:25:00 (meaning 25 minutes), to = 00:31:12 (meaning 31 minutes, 12 seconds) and the output should be the section from the main audio file, the result is 00:06:12 (meaning 6 minutes, 12 seconds) long.

    How can this task be achieved with the project ? Also a C example can help me, I would try to convert it into the framework.

    Thanks for your responses.
