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

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

2. 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(); 
}
 }

Thanks for making such an awesome library.
Can anybody explain how can i select video from gallery to add effect on it?

Hi,

As you mentioned in ReadMe that In the future, you are aiming to apply permanent effect to videos. So, i wanted to ask about the approach you would be following to implement this behaviour.

Hello,

As you mention here for permanent video effecting and saving video in sdcard.

As you mention in demo colorchannelmixer=.393:.769:.189:0:.349:.686:.168:0:.272:.534:.131 i want different Frame filters for diffrent effects which you mention in your library

BrightnessEffect, ContrastEffect, AutoFixEffect, BlackAndWhiteEffect, CrossProcessEffect

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(); } }
