chromakey filter

[FanSerg2]

I have video with green background. I can use ffmpeg with chromakey filter in command line on Windows.
ffmpeg -i video.mp4 -i punch_green.mp4 -filter_complex "[1:v]chromakey=0x12da11:0.2:0.2[chromakey_res];[0:v][chromakey_res]overlay=eof_action=pass[out]" -map "[out]" out.mp4
This example gets second video, removes green background and then overlays it on first video.

How can I do this with FFmpegFrameFilter?

When do I try execute this code
FFmpegFrameFilter filter = new FFmpegFrameFilter("chromakey=0x12da11:0.2:0.2", grabberEffect.getImageWidth(), grabberEffect.getImageHeight());
I take next error
Error: No such filter: 'chromakey'

This works just fine here. I get no errors.

I downloaded and installed javacpp-presets module with gradle:

compile group: 'org.bytedeco.javacpp-presets', name: 'ffmpeg', version: '2.8.1-1.1', classifier: 'android-arm'

Am I using the latest version ffmpeg (3.0.1)?

If I write
compile group: 'org.bytedeco.javacpp-presets', name: 'ffmpeg', version: '3.0.1-1.1', classifier: 'android-arm'
I am getting an error:
Failed to resolve: org.bytedeco.javacpp-presets:ffmpeg:3.0.1-1.1

How I can see the version ffmpeg in my project?

Try to install it manually: https://github.com/bytedeco/javacpp-presets/#manual-installation

I added next files:

    compile files('libs/ffmpeg-android-arm.jar')
    compile files('libs/ffmpeg.jar')
    compile files('libs/javacpp.jar')
    compile files('libs/javacv.jar')

and get this error :

chromakey filter was added in ffmpeg version 3.0

JavaCV 1.2 uses FFmpeg 3.0 so this should now work. Enjoy!
