  • H.264 decoder for python or node.js

    5 septembre 2015, par Domagoj Šitum

    Is there any h.264 decoder for python (preferably) or node.js ?
    I’m working on some project which uses AR.Drone 2.0. Parrot. What I need to do is get Parrot’s h.264 stream, display it in web browser and at the same time process it in OpenCV (in python). I’ve managed to display that stream in Web browser, but I’m struggling to feed it to OpenCV (in python).
    Here is how it all goes. node.js connects to Parrot’s video stream. After that, Parrot (the drone) starts sending h.264 I- and P-frames as TCP packets with some non-h264 header data. node.js removes that header data and determines if frame is of I or P type. After that, node.js script sends that frame to client (Web browser) for decoding and displaying, and also to python (via socket) which somehow has to pass that frame to openCV.
    Now, Web browser (Javascript) uses this great h.264 decoder, Broadway :
    https://github.com/mbebenita/Broadway
    to decode single I or P frame into YUV data. And it works flawlessly ! But I can’t get the same functionality in python (or at least at node.js side). So, is there any way that I could decode that I- and P-frames into YUV (or RBG) images in python or in node.js ? Or could I feed openCV with I- and P-frames directly ? Could FFmpeg help me ?
    Please don’t tell me to send decoded frames from Javascript (client) back to python, because I’ve tried it - and it makes video decoding significantly slower and laggy (because Javascript is single-threaded language and I’ve obviously given it too much work to do). I’ve even tried to use Broadway’s h.264 decoder inside node.js, but I’ve had no success.
    Any solution is welcome !

  • x264 command line options for openh264 decoder

    6 octobre 2015, par David

    OpenH264 is a pretty restrictive decoder. It only decodes baseline, for one thing. I’m using openh264 to decode something encoded with x264 and every 1-10 seconds I’m getting busts of 10-20 frames of decoding errors : dsRefLost, dsBitstreamError, and/or dsDataErrorConcealed. I’m thinking this may be due to x264 set to encode in a way OpenH264 doesn’t support to decode. What options should I use for x264 to make sure openh264 can decode properly ?
