    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.

  • How to convert my 16:9 size MKV video to 4:3 size AVI video file

    10 avril 2013, par Bimal Rekhadiya

    I have a video in MKV format and it's size is 720x304 (16:9 ratio) size video.

    I want to convert it to AVI format (using xvid video codec). The output file size should be 480x360 (4:3 ratio) and also want to keep the original (16:9) ratio so it should be cinemascope (black areas at top and bottom).

    I am on Ubuntu Linux so I can use mencoder, avconv(ffmpeg) or any tool that work on Linux.

    I tried this command :

    avconv -i sample.mkv -vcodec libxvid -r 25 -b 1200 -aspect 4:3 -q 1 t.avi

    But the problem is that the video is stretched to 4:3 and I want to keep original video's ratio and want to add black boxes at top and bottom so it will look like a "CinemaScope".

    What is the best way to do this ?

    I’m trying to convert a mov video to flv, but keep getting these errors below.
    There are 2 commands I used, both are below.

    ffmpeg -y -i video.mov -deinterlace -acodec copy -r 25 -qmin 3 -qmax 6 video.flv

Could not write header for output file #0 (incorrect codec parameters ?): Invalid data found when processing input

    1 more thing please :
    If I use this newer version of ffmpeg to create a video with the below command, I get a video with a very hazy display.
    It’s like a few black dots on a blank screen :

    ffmpeg -i img%d.png -i audio.wav -acodec copy output.mov

    what could be the reason for this display ?

  • FFmpeg's trim filter to handle movie files with non-zero start_time for a transcoding task ?

    19 août 2014, par Drake

    For a movie file (ex, ooxx.mp4) with non-zero start_time in video stream, the negative start_time (ex, -0.5) can mean skipping first 0.5s frames, and the positive start_time (ex, 0.7s) can mean postponing the playback for 0.7s.

    I’m wondering if we can make use of FFmpeg’s trim filter (or something else) to strip out some video frames (for negative start_time) or put some empty (ex, black) frames ahead (for positive start_time) automatically ?
