  • Uploading video, with PHP serverside formatting & encoding

    29 janvier 2013, par Nelga

    We've currently developed an ExpressionEngine site (php), and are using a paid JWPlayer to display video uploaded by the client.

    At present we're running into a number of issues, as the client is :

    1. Uploading video at the wrong size
    2. Uploading video randomly in both flv or mp4 format

    And the player is chugging along terribly with multiple pauses throughout the video - sometimes buffering the entire clip before it is played.

    I know FFMPEG can be installed serverside, but I'm not sure of the way in which to go about this, and how it might interact between ExpressionEngine and JWPlayer. I'm also not sure about the formatting - the ability for this automated encoding process to also crop/resize the video to suit the player dimensions on the site.

    We would really like to have the videos playable on all browsers & iOS devices.

    A HQ option would also be great where applicable, but it's just a nice to have - as we're struggling with the formatting / encoding issues first and foremost.

    Any help figuring out the best process, and what tools I might need would be greatly appreciated.

  • Extract audio amplitude from video

    11 janvier 2012, par Andrew

    I need to process >200 videos by getting several snapshots from each one.
    Each snapshot will be taken if the volume is higher than 'x'.
    So I can make snapshots with FFMPEG but I don't know how to extract the amplitude graph.
    How can I get an array with the audio volume of each frame ?

  • 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.
