  • Other interesting software

    13 avril 2011, par

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Encoding a live stream of bitmaps using FFMPEG

    1er avril 2015, par user3088260

    I’ve got a constant stream of jpeg’s that need to be converted to a video (of any kind).
    The problem is that the stream is virtually infinite and I don’t know any method of creating videos using pictures that doesn’t store the whole file in memory until the stream stops..

    Is there a way that I can feed FFMPEG with bitmaps or jpegs constantly from c# or at least make ffmpeg read images from a folder with +432000 images (on the command line) ?

    Please note that there will be no sound, the images will be low quality, they will come at a rate 5 FPS and this will run on a high-ish end laptop. BTW I can provide code but I assume this is unnecessary at the moment as I am only creating bitmaps and saving them.

  • Insert background image using FFmpeg

    9 février 2015, par Yannick

    I’ve just started using FFMpeg and I’m trying to create a video slideshow from images

    I have the following

    "ffmpeg -framerate 1/5 \
    
-start_number 1 \
    
-i "C:/test/%03d.jpg" \
    
-vf 'movie=C:/test/bg.jpg [over], [in][over] overlay'
    
-c:v libx264 \
    
-r 30 "C:/test/video.mp4"

    And that works perfectly to create slideshow with the pictures but how can I add a background image ?

    I’ve looked at the command -overlay command but I can’t seem to make it work.

    Thanks for the help.

  • How to trigger from button in UVC camera

    8 août 2016, par Buddhishan Manamperi

    I’m taking pictures from a webcam using Intel Edison. I was able to capture still images from the camera after installing uvc driver for linux and ffmpeg software. I use a script to capture.

    ./ffmpeg -s 640x640 -f video4linux2 -i /dev/video0 -vframes 1 image.jpeg;

    I want to capture the image from the button (in the web cam) press event. I used a USB analyzer in windows to analyze packets. It was found that URB_FUNCTION_BULK_OR_INTERRUPT_TRANSFER is transferring UP and DOWN when the button is pressed.

    Please Help me to implement button press triggering on Linux so that I could use it on Edison.
