  • IOException : Error running exec() Command, When calling FFmpeg method

    21 avril 2016, par kc ochibili

    i am trying to create a slide show mp4 using this ffmpeg method but i keep getting this IOException Error running exec(). Command when i click the button.

    here is my call

    ffmpegController = new FfmpegController(getTempDirectory(), new File(""));
    
ffmpegController.createSlideshowFromImagesAndAudio(slideFrames, getAudioPath(), getOutPath(), 500, mCallbackResponse);

    Here is the source code of the small project.
    Here is the apk

    And here is my Error message

       Error running exec(). Command: [ffmpeg, -y, -i, /storage/emulated/0/TestFFmpeg/frame1.png, /storage/emulated/0/TestFFmpeg/temp/image-000.jpg]

  • Filter complex apply on ffmpeg for android outputs low quality video

    17 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 :
