  • Capture video on iOS device and live stream it to a server (or another mobile)

    13 février 2015, par theDuncs

    I want to be able to record footage using my iOS device and stream it directly to a server.

    There’s quite a few articles on S.O. that talk about this, but I’m not sure any have answered the question very well.

    Should I be using HTTP Live Streaming, or is this just for sending data to an iPhone ?
    Should I be using AVCaptureSession to grab the video (a segment at a time ?), sending each segment to the server ?
    Should I be using AVCaptureVideoDataOutput and ffmpeg for streaming ?

    I’m a little lost with all this, so any sample code or docs or links would be really appreciated.

    Thanks for your help guys.

  • OpenGLES glReadPixels exc_bad_access

    29 novembre 2011, par Yanny

    I'm trying to create video from images using OpenGLES and ffmpeg, but on iPad(4.3) I have a crash on glReadPixels

    -(NSData *) glToUIImage {
    

    
    int numberOfComponents = NUMBER_OF_COMPONENTS; //4
    
    int width = PICTURE_WIDTH; 
    
    int height = PICTURE_HEIGHT;
    

    
    NSInteger myDataLength = width * height * numberOfComponents;   
    

    
    NSMutableData * buffer= [NSMutableData dataWithLength :myDataLength];    
    

    
    [self checkForGLError]; 
    

    
    GLenum type = NUMBER_OF_COMPONENTS == 3 ? GL_RGB : GL_RGBA; //RGBA
    
    glReadPixels(0, 0, width, height, type, GL_UNSIGNED_BYTE, [buffer mutableBytes]);   //EXC_BAD_ACCESS here
    

    
    return buffer; 
    
}

    It is working on iPhone 4 (4.3) and iPod Touch, but have problems on iPhone 3G(3.0) and iPad(4.3). Can you help me with this issue ?

    Also on iPhone 3G(3.0) and iPad(4.3) I have problems with Video - first 5-20 video frames have trash. Maybe issue with optimization ? Or architecture ?
