  • Reading avfoundation video device using FFMPEG library

    22 juin 2015, par Nipun

    I want to capture the screen on mac machine and dump into a file.

    ffmpeg -f avfoundation -i "1" -f mpeg1video screendump.mp4

    So I would like to achieve the same using programming in C/C++ using ffmpeg library.

    How do I receive the stream in a C/C++ program using FFMPEG library ?

    How do I write the received video into a file ?

  • Reading geolocation data from a video file using FFMpeg/Xuggler

    23 décembre 2015, par agent154

    Using the MediaInfo application, I am able to see that a file taken with an iPhone 5 contains geolocation metadata, tagged both with ©xyz and com.apple.quicktime.location.ISO6709. I am not able to find any way to get this data using xuggler, however.

    Format                                   : MPEG-4
    
Format profile                           : QuickTime

com.apple.quicktime.software             : 8.4.1
    
com.apple.quicktime.model                : iPhone 5

    As an aside, there seems to be a lot of metadata on this file that I can’t immediately find while debugging via xuggler.

    The question at Reading Geolocation from Quicktime Movies with Java (Xuggler) ? is asking the exact same question, but has no answers or comments at all, and is over 4 years old.

    Is anybody aware of a way to be able to get this data using xuggler as it is, or how I can modify the source and re-compile to make it work ? I am required to get this data for a work project. Thanks.

  • Reading a UDP stream by ffmpeg libavcodec

    9 janvier 2014, par Blue Sky

    I want to read a video stream using ffmpeg libavcodec from a UDP address like udp ://:1500. I am using this code :

    char *url = "udp://:1500";
    
char *format = "mpegts";
    

    
AVInputFormat *fmt = NULL;
    
AVFormatContext *oc = NULL;
    

    
int res;
    

    
fmt = av_find_input_format(format);
    
res = avformat_open_input(&oc, url, fmt , NULL);
    
if(res!=0){
    
     printf("Could not open the stream\n");
    
     exit(1);
    
}

    But when I run this code, the program halts forever after executing res = avformat_open_input(&oc, url, fmt , NULL) ;

    Do you know what is the problem ?
