  • Applying filter complex fails with something related to audio

    18 septembre 2014, par Alin

    I finally managed to build ffmpeg as detailed in here : https://enoent.fr/blog/2014/06/20/compile-ffmpeg-for-android/ and in the end, I have a ffmpeg library which accepts command arguments.

    I am trying to apply a watermark image over the video so for it I am using preparing this ffmpeg command :

    ffmpeg -i input.avi -i logo.png -filter_complex 'overlay=10:main_h-overlay_h-10' output.avi

    I have first tried it on windows using ffmpeg.exe and the result was as expected.

    I have tried it on android using the compiled android and the output is as follows :
