  • Http live streaming for ipad, iphone and safari

    23 février 2013, par Riyas Anchal

    Anyone help me to find a solution to stream a video from a mac server to iPad, iPhone and mac safari using HTTP live streaming.

    Steps taken :

    1. Installed and configured FFMPEG for encoding
    2. installed the mediasegmenter provided by the Apple.

    The ffmpeg option used is

    ffmpeg -y -i input.mp4 -acodec aac -ar 48000 -ab 128k -ac 2 -s 1024×768 -vcodec libx264 -b 1200k -flags +loop+mv4 -cmp 256 -partitions +parti4x4+partp8x8+partb8x8 -subq 7 -trellis 1 -refs 5 -coder 0 -me_range 16 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -bt 1200k -maxrate 1200k -bufsize 1200k -rc_eq 'blurCplx^(1-qComp)' -qcomp 0.6 -qmin 10 -qmax 51 -qdiff 4 -level 30 -aspect 4:3 -r 30 -g 90 -async 2 output.mp4

    I have tried different ffmpeg options to stream the video.In some options it works in Iphone and Safari browser in mac machine, but I didn't get an option for iPad.

    I want to stream an mp4 video for ipad, iPhone and mac safari. I also tried it with opensource segmenter .

    Have any solution for this ?

    Thanks,

  • 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

  • iPhone slow motion video transcode

    28 septembre 2019, par coverboy

    I’m developing upload video (taken from iPhone) to my server.

    However, I have no idea how to implement.

    Any source code objective-c or swift will be welcomed.

    I have 120fps or 240fps video (It’s a slo-mo).
    When I playback these video on my iPhone6. I can see slo-mo effect.
    (I know playback frame rate is 30fps.)

    I want to convert that video before upload to my server, from 120/240 fps to 30fps video. (I mean not adjusting playback frame rate, it means video transcode to 30fps.)
    Additionally, I want to check slo-mo effect start-point and end-point.
    (Maybe iPhone record this information to video binary(it might be reside in file’s header.)

    Well, I guess if I use ffmpeg library, it should be easy(?).

    So any suggestions will be welcomed.
