  • 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".

  • Use FFMPEG to create video from jpeg, and index using vlc

    16 novembre 2011, par Greg

    OpenSuse 11.4
    FFMEG 0.8.5

    I'm using FFMPEG to create a 5 minute mpeg from about 2100 individual jpegs (7fps). I've been using the following command (OpenSuse 11.4)
    /usr/bin/ffmpeg -y -r 7.01 -i %03d-capture.jpg -s 800x600 -r 25 Event-3692-r1-s1-3.mpg

    Now I Try to open the file (In windows XP with VLC 1.1.11 Player).
    Media->AdvancedFileOpen
    *I select "Show more options" and set StartTime to 5s. I expect that the video should start 5 seconds in, but instead it starts at a seemingling random (although consistent) time of 30 seconds in.

    I also tried changing ffmpeg command to :
    /usr/bin/ffmpeg -sameq -y -r 7.01 -i %03d-capture.jpg -s 800x600 -r 25 Event-3692-r1-s1-3.mpg
    *This result in about a constant 2x offset (5sec => 10sec) (10s => 20s) etc. But filesize is also about 6x larger, which is a strain on my storage.

    I also tried
    /usr/bin/ffmpeg -y -r 7.01 -i %03d-capture.jpg -s 800x600 -r 25 -f mpegts Event-3692-r1-s1-3.mpg
    *This result in vlc not indexing at all into my video. Also not desired. Anybody have any clues what is going on here. It is very important for me to be able to use this VLC feature and have it work correctly.

    Thanks in advance

  • HTML5 Video FFMPEG Shell Script

    18 novembre 2011, par Schermy

    I wrote this quick and dirty shell script to run ffmpeg over a bunch of files to generate webm/ogg/h.264 videos for a HTML5 site.

    #!/bin/bash
    

    
ext=$1
    
enc=$2
    

    
#!/bin/bash
    
for file in *.$ext; do
    
        while pidof /usr/local/bin/ffmpeg; do sleep 10; done >/dev/null
    

    
        ffmpeg -i "$file" -s 1280x720 -b 500k  "${file/%$ext/$enc}"   
    
done

    It works great for my purposes but I've noticed that each video now takes a lot longe to convert and ffmpeg is not taking advantage of my multi-core setup.

    I would like to improve this script when I have some time and make it available for use by others but I'd like to solve this issue first.

    Thanks in advance for all of your help.

    P.S. This is setup to use the ffmpeg installation from brew on the Mac (and yes I would like to make this script more platform agnostic later on).

  • Capture video on iOS device and live stream it to a server (or another mobile)

    13 février 2015, par theDuncs

    I want to be able to record footage using my iOS device and stream it directly to a server.

    There’s quite a few articles on S.O. that talk about this, but I’m not sure any have answered the question very well.

    Should I be using HTTP Live Streaming, or is this just for sending data to an iPhone ?
    Should I be using AVCaptureSession to grab the video (a segment at a time ?), sending each segment to the server ?
    Should I be using AVCaptureVideoDataOutput and ffmpeg for streaming ?

    I’m a little lost with all this, so any sample code or docs or links would be really appreciated.

    Thanks for your help guys.

    Duncan
