  • Colorspace conversion in FFmpeg

    19 mars 2014, par learner

    I am looking forward to implement RGB->YUV444P colorspace conversion using FFmpeg/C++ as given on first few lines on this page. However, I am not able to excess pixel values of a frame with the FFmpeg library ! Any idea how to implement this usinf FFmpeg ?

  • Trying to use FFMPEG for android. Compiling but still not working

    15 avril 2014, par Austin Mueller

    So to start off... Im trying to use ffmpeg to compile an array of images into a video on Android.

    I have followed a variety of tutorials online and have gotten as far as being able to compile the lib for Android and still have to project run.
    The repo im now using can be found here : https://github.com/Batterii/android-ffmpeg-x264

    I made a couple tweaks to the setttings.sh just to correct ndk location. Besides that, I followed the instructions and it seemed to work flawlessly.

    After that, I converted the "Project" project into an Android stdio library module.
    Screenshot of android studio module

    I am not getting any compile errors, nor am I getting any runtime errors, or any other errors that I can detect... Nothing on logcat... But I am definitely not getting any video called out.mp4.
    In an onCreate of a particular activity, I am running this code :

    Videokit vk = new Videokit();
    
vk.run(new String[]{"ffmpeg", "-r", "1/5", "-i", "%d.jpg", "-c:v", "libx264", "-r", "30", "-pix_fmt", "yuv420p", project.getProjectDirectory() + "/out.mp4"});

    This command is taken from the command line example found here :
    https://trac.ffmpeg.org/wiki/Create%20a%20video%20slideshow%20from%20images

    Thank you in advance for anyone taking the time to look through this post... I am pretty baffled at this point, as there are no errors I can find and no video...
    Thanks

    Update

    Turns out it is not actually compiling correctly... but i have found a few things.
    here is the make file from the Eclipse version of the project

    LOCAL_PATH := $(call my-dir)
    

    
include $(CLEAR_VARS)

    I've been messing around with it for a couple hours now and pretty much every time, i get gradle yelling at me about the fact that it can't find some file. I'm beginning to think that maybe it is because my LOCAL_LDLIBS aren't in the same order as the original...? Im not entirely sure... Does anyone else have any ideas...?
