  • Convert ARGB8888 image into single frame YUV422P10LE using FFMPEG [on hold]

    30 novembre 2017, par user1950676

    I’m doing video conversion using certain tools that outputs raw RGBA/RGB images, and wanted to convert individual frame into YUV422P10LE pixel format before saving it as video file.
    How do I do this using libswscale (using C) ?
    Also, as I look at the -help from ffmpeg, it does not have catmulrom flag for scaling, is there any equivalent for that ?
    Thanks before :)

  • Creating MPEG4 video file with Python from raw frames

    11 août 2016, par Mikko Ohtamaa

    I have a raw video frame source which I can access in Python. I’d like to create a MPEG4 video out of this, with MP3 background music.

    What kind of tools and libraries are available in Python for such a task ? Preferably I’d like to have an API for which I can feed output filename and then individual frames as 24 bit raw images.

  • Feeding a series of images to ffmpeg as each image is created [closed]

    5 février 2013, par Mark Schneider

    I'm trying to use ffmpeg to build a 1280x720 slide-show from a sequence of pictures and videos, but I have concerns about potential disk I/O bottleneck.

    I expect a typical slide-show to have about 50 pictures and 2-3 videos (10-15 seconds each at 30 fps). I would like to show each picture for 3-4 seconds (possibly with a
    Ken Burns effect) with a smooth 2 second crossfade between each set of pictures (or for pictures adjacent to videos - between the picture and the first/last frame of the video).

    Given about 50 pictures, the crossfades alone would amount to about 3,000 images (50 transitions x 2 secs/transition x 30 fps). And I suppose if I implement a Ken Burns effect during each picture's 3-4 second showing, I'd have to provide ffmpeg with individual images for each of those frames. (I'm writing a script in Ruby that will pull a list of images from a database and in turn call ImageMagick to create the individual images for each frame. As I understand it, the RMagick library interfaces with ImageMagick such that the output images come back as in-memory objects without needing to write to disk. FWIW, I'm developing in Windows 8 and will deploy to Heroku.)

    All of the slideshow examples I've found online feed ffmpeg a set of images which have already been created. However, in an effort to avoid waiting on considerable disk I/O, I'd like to feed each image to ffmpeg as the image is created rather than create them all in advance.

    Is there a way to send each image file to ffmpeg on the fly as the file is created in memory ?
