  • FFMPEG : Need to mix dow multiple audio stream to single stereo

    17 avril 2018, par Serge Dumoulin

    I have an input file with 2 stereo stream of audio.
    I am trying to create an output wav file with the audio mixdown :
    first stereo stream mixdown to left channel of a single stereo stream
    Second stereo stream mixdown to right channel of the same stereo stream.
    So output file have only one stereo stream.
    I have tried different things but its not clear how to manage streams and channels inside them. Found no example on how to do this.

    I’ve tried playing with -filter_complex , amix, and amerge filters, as well as the -map parameter, but I can’t seem to find the right combination of values.

    Here was my input file looks like :

    I have a video that I get from a third party provide in my App, I want to play using react-native-video. It works fine on simulator, but on a real iphone 7 it has only sound but no video.

    After further research I found, when I try to airdrop/move via itunes the video to my iphone. It shows something like the following :

    Then I tried VLC on iOS the video played without problem (it has both video and sound), except at the beginning it shows a grey pixel screen.

    enter image description here

    Next, what i did was using ffmpeg to re-encode the video stream via :

    ffmpeg -i bad.mp4 -c:a copy new.mp4

    After this new.mp4 plays with no problem.
    This is really confusing as the codec does not change and both videos works with no problem on my Mac.

    I have tried to play around with the b_frames, profile level on the new video to reproduce the problem but with no luck.

    I really do not want to process every video via ffmpeg after get it from the third party. Just wondering what might be the problem with the video ?
