  • Extract image of every frame of a video using react-native-ffmpeg

    1er octobre 2020, par EdG

    I have looked all over the internet to get a way to extract image of everyframe of a video using react-native-ffmpeg. I am making a mobile app and I want to show all per frame images on the video timeline. I want to do this natively on mobile so that I can utilise hardware power of mobile. That is the reason I am looking for react-native-ffmpeg kind of library. Am I in the right direction ? This npmjs.com/package/react-native-ffmpeg is what I am trying to use. I need to know the command to do the job.

  • Invalid option error using avcodec_open2 and libopus

    26 octobre 2020, par Paul Gregoire

    I'm getting an invalid option result from avcodec_open2 in ffmpeg 3.1.6 with libopus 1.1.4. I've sorted through all the options and I cannot locate the offending option, I created a gist holding the relevant native code. I've searched all about the internet and cannot find anything helpful as of yet. I've also tried with and without the opts dictionary.

    


    results = avcodec_open2(context, codec, &opts);


    


    and

    


    results = avcodec_open2(context, codec, 0);


    


    All tests and variations return -22 (at line 51 in gist)
