  • iPhone camera live steaming

    15 juin 2012, par Inder Kumar Rathore

    I have downloaded ffmpeg lib file and complied it for armv7. I added ffmpeg lib files in my project successfully. i am able to get iphone camera live streams using AVFoundation.

    Now the problem is how will i convert iphone camera streams output as a input of ffmpeg for decode ? Check my code

    - (void)captureOutput:(AVCaptureOutput *)captureOutput didOutputSampleBuffer:(CMSampleBufferRef)sampleBuffer fromConnection:(AVCaptureConnection *)connection {
    

    

    
CMBlockBufferRef bufferData = CMSampleBufferGetDataBuffer(sampleBuffer);
    
size_t lengthAtOffset;
    
size_t totalLength; char* data;

    if(CMBlockBufferGetDataPointer(bufferData, 0, &lengthAtOffset, &totalLength, &data ) != noErr )
    NSLog(@"error !") ;

    Kindly suggested me which function of ffmpeg lib is used for decoding and how will i put CMBlockBufferRef as a input of this ??

    Thanks

  • Encoding videos for use with Adobe Live Streaming

    10 mai 2016, par FiddleMeRagged

    I have an original video coded at 20Mbps, 1920x1080, 30fps and want to convert it down to be 640x480 30fps at a range of (3 different) bitrates for use by Adobe Live Streaming.

    Should I use ffmpeg to resize and encode at the 3 bitrates then use f4fpackager to create the f4m f4f and f4x files or just use ffmpeg to reduce the resolution and then f4fpackager to encode the relevant bitrates ?

    I’ve had several tries so far, but when encoded the videos seem to play at a much larger bitrate than they’ve been encoded at. For example, if I set up the OSMF to play from my webserver, I’d be expecting my best encoded video to play at 1,500kbps but it’s way above that.

    Has anyone had any experience of encoding for use like this ?

    I’m using the following options to f4fpackager

    --bitrate=1428 --segment-duration 30 --fragment-duration 2
