ffmpeg missing blend filter
13 mars 2014, par user2927954I am working on android project using ffmpeg library. I followed instruction from : https://github.com/guardianproject/android-ffmpeg to build ffmpeg library for android. All are OK.
Now, i am testing filters that corresponding to video filter of this library such as : drawtext, scale, pad, ... Most of them worked fine, but i have problem with "blend" filter.
I try with commands : ffmpeg -i input1.mp4 -i input2.mp4 -filter_complex blend=all_expr='if(eq(mod(X,2),mod(Y,2)),A,B)' -y out.mp4 and recieve error : no such blend filter.
Do you know how i configure to enable this filter ?
Here is the output result :
