  • Is it possible to use ffmpeg in nwjs native addon in linux ?

    16 octobre 2016, par Sergey Yakimov

    I’ve created native addon for encoding video from IDS camera. It work in nodejs but after rebuilding it with nw-gyp it stop working. I checked available encoders and there is none. When nwjs loads addon I think it using ffmpeg which come with nwjs and it have only few decoders compiled in and no encoders. In nwjs docs they only describe how one can enable h264 codec, but if I understand it right it will work only as decoder.

    So is there a way to make addon use system ffmpeg instead of that what come with nwjs or at least rebuild ffmpeg used in nwjs to include encoders in it ?
