Description

The mp4 files created with FFmpegFrameRecorder has no thumbnails. I tried many libraries to create thumbnail and add into file but couldn't manage due to not supported codec error. The initializing code :

        Loader.load(ffmpeg.class);
        recorder = new FFmpegFrameRecorder(ffmpeg_link, imageWidth, imageHeight, 1);
        recorder.setFormat("mp4");
        recorder.setVideoCodec(avcodec.AV_CODEC_ID_MPEG4);
        recorder.setSampleRate(sampleAudioRateInHz);
        recorder.setFrameRate(frameRate);

What should be the solution for Android environment?
