  • Video Filters like Instagram and save in SDCARD

    7 mai 2018, par Harsh Bhavsar

    Color Channel Mixer (Info.)
    https://ffmpeg.org/ffmpeg-filters.html#colorchannelmixer

    I am trying to creating video filters using FFMpeg and OpenCV just like Instagram Video filters.
    So if I want to create Sepia Effect Then I have to use color channel mixer for that with RGBA values
    ex. colorchannelmixer=.393 :.769 :.189:0 :.349 :.686 :.168:0 :.272 :.534 :.131 (This code for Sepia Effect)
    Now I want to create more effects like Instagram. So need different color channel mixers for that
    How to create them ?

    Ref. — https://github.com/krazykira/VidEffects/wiki/Permanent-video-effects

    I got only 2 filters

    Sepia
    colorchannelmixer=.393 :.769 :.189:0 :.349 :.686 :.168:0 :.272 :.534 :.131

    Grayscale
    colorchannelmixer=.3 :.4 :.3:0 :.3 :.4 :.3:0 :.3 :.4 :.3

    I need more filters.

    private void initVideoRecorder(String path) { 
    
try { 
    
filter = new F FmpegFrameFilter("colorchannelmixer=.393:.769:.189:0:.349:.686:.168:0:.272:.534:.131", VIDEO_GRABBER.getImageWidth(), VIDEO_GRABBER.getImageHeight()); 
    
videoRecorder = FFmpegFrameRecorder.createDefault(path, VIDEO_GRABBER.getImageWidth(), VIDEO_GRABBER.getImageHeight()); videoRecorder.start(); 
    
} 
    
catch (FrameRecorder.Exception e) { 
    
e.printStackTrace(); 
    
}
    
 }

  • Compilation error when compiling libvpx for FFMPEG

    29 septembre 2014, par Flock Dawson

    I’m compiling FFMPEG on my 64bit Ubuntu 14 machine. Everything compiled well, except for the libvpx library, which keeps throwing errors :

    [AS] vp9/common/x86/vp9_subpixel_8t_ssse3.asm.o
    
vp9/common/x86/vp9_subpixel_8t_ssse3.asm:856: warning: label alone on a line without a colon might be in error

make[1]: *** [vp9/common/x86/vp9_subpixel_8t_ssse3.asm.o] Error 1
    
make: *** [.DEFAULT] Error 2

    I followed this guide : https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu
    I don’t know what this error means, but read somewhere that compiling libvpx with NASM is broken, but I don’t know how to compile it otherwise. Installing version 1.2 or 1.1 makes no difference whatsoever. Any ideas ?

  • AMV video encoder ?

    15 novembre 2011, par Shimmy

    I'm looking for a converter that can encode input files to amv format output.

    I've found this project, but it looks somewhat outdated and not maintained.
    Do you know of a solid and reliable amv encoder (any API or tool that can be invoked from .NET), or can you recommend on the one I mentioned ?
