  • Supporting all media types

    13 avril 2011, par

  • What are the APIs for hardware accelerated video decoding in phones ?

    11 janvier 2012, par cloudraven

    I have seen many smartphones coming with hardware accelerated video decoding supporting mpeg2 and h264, but unlike in desktop and laptop systems, it is not clear to me how to interact with the hardware acceleration.
    For desktops/laptops there is DXVA, VDPAU and OpenMax.
    Is any of those supported in Mobile phones ? I think OpenMax is, but I am not sure of how widely supported it is.

    Is anyone familiar with what is usually used to write hardware accelerated media players and decoders for platforms like Snapdragon, Tegra 2 or Omap 4 running Android or Windows Phone ?
    I know that ffmpeg can be compiled for arm and I wonder what kind of hardware video acceleration it supports on that platform.

  • Streaming live video from ios

    12 février 2014, par John

    I have a need to stream video from the iPhone/iPad camera to a server. It looks like this will need to be done with AVCaptureSession but I don't know how to best architect this.

    I found this post :

    streaming video FROM an iPhone

    But it doesn't handle the "live" part, latency needs to be 2 or 3 seconds at most. Devices can be constrained to 4 or 4S capability if needed, and there is no requirement for HD, VGA is probably what we'll end up with. I assume any solution would use ffmpeg, I haven't found any more appropriate library.

    How is this best accomplished ?

  • Xuggler encoding images to video FPS issue

    1er novembre 2011, par Chris Robinson

    I've been experimenting with encoding a video from a series of images using CaptureScreenToFile.java as a basis. My output is to be an MP4 file. From 26 images, using the code as is (taking the images from a directory instead of from a screen capture obviously), the encoding video is 11s. However, if I change the framerate variable to :

    frameRate = IRational.make(1, 24);

    which I believe should result in a video of 24FPS. It does not however, (no change from the original video in fact). I experimented with changing the timeStamp variable in encodeImage() method to :

    long timeStamp = (firstTimeStamp*1000)+(i*40);

    where 0 < i < 25 to see if that would help but it doesn't. Can anyone explain to me how to encode a directory of images to a video with a framerate that I can set ?
