  • Video streaming with ipCamera in iphone

    6 juillet 2013, par user1120998

    I am developing app for the connecting ip camera and get stream. I don't know how to convert stream into video. I have analysed, and then i tried FFMPEG library. But i did not get correct url for ios with FFMPEG. Can you suggest the guide for implementation.

    Now i am integrating ffmpeg, when i integrated i got the error when opening avformat_find_stream_info() function. I used the increase or less the value of pFormatCtx->max_analyze_duration. But no solution for this.

    [mjpeg @ 0x8b85000] max_analyze_duration 1000 reached at 40000
    [mjpeg @ 0x8b85000] Estimating duration from bitrate, this may be inaccurate

    Pls help how to solve this.

  • Display YUV420P video using OpenGLES on iPhone

    25 décembre 2014, par user3487978

    I am writing an app displaying YUV420p video using ffmpeg library on iPhone, every thing works fine, but the OpenGL color is a little strange, see picture, the bellow image is displaying using AVPicture in RGB format, above is using AVPicture in YUV format.
    any ideas ?
