  • Android Video Compression [on hold]

    10 mars 2015, par Arif Gencosmanoglu

    I am planning to build a small Android JAVA application that compresses images and videos. I did the image compression part and my .apk size is 1.5MB. However when I do the video compression part by using ffmpeg the application size goes up to 20.0MB. This library has tons of features that I am not using. I only need a simple video compression module to add.

    Is there any other video compression methods or functions that will be useful ?

    Thanks.

  • ffmpeg : 1 frame manipulation on demand

    7 juillet 2013, par Chris Russo

    Hello folks & friends of SO !

    We need to create a small application to take a random frame from a video, and apply some modifications to it, in real time.

    This has to be done in real time, and in order to do that, we wouldn't mind to create some initial delay, before the video starts streaming. So let's assume we have a total of 6 seconds of preloading time, in order to :

    1) extract a keyframe.
    
2) create an image with it.
    
3) manipulate the image.
    
4) replace the original keyframe with the new one.

    The point (3) of the previous algorithm is already solved using GD as a PHP module. However we would need to find a solution for the rest of the procedure in order to accomplish this.

    Please if anyone is available to help us with this, feel free to contact me.

    Thanks in advance ;
    Chris C. Russo
