  • 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.

  • "ffmpeg has text relocations" error in Android

    5 janvier 2015, par djzmo

    I’m building an Android video-sending application. I need the video to be compressed before being uploaded. In this case, I chose to use this Android wrapper of FFmpeg : https://github.com/hiteshsondhi88/ffmpeg-android-java

    FFmpeg error: WARNING: linker: /data/data/com.mycompany.myapplication/files/ffmpeg has text relocations. This is wasting memory and prevents security hardening. Please fix.

    Everything seemed fine when I compress small files (below 20 seconds), but when I tried to compress larger files, I seldom get the above error in the middle of the compression process, and the process was also terminated immediately. I need the application to be able to compress one minute video to about 20-35 MB.

    Here is the FFmpeg command I used :

    ffmpeg -y -i -codec:v libx264 -profile:v baseline -level 3.0 -b:v 2500k -minrate 2500k -maxrate 2500k -bufsize 1835k -pix_fmt yuv420p -preset ultrafast -crf 28 -codec:a copy

    Any idea on what went wrong ?
    Any kind of help would be very appreciated.

  • Encoding real, source duration of a timelapse into MP4 container using FFMPEG (GoPro) [closed]

    This information could be omitted.
    
But it becomes quite important for correctness of GPS Data stored in Stream #2.

    


    Unfortunately, all the settings I have tried for FFMPEG, do not preserve the duration of Stream #2.
& the output ends up looking like this :
