  • lavu : add av_gettime_relative()

    lavu : add av_gettime_relative()

    These functions are using the POSIX clock_gettime() function with the
    
CLOCK_MONOTONIC clock id. If these are not present on the targeted
    
platform, the new functions will fallback on using the original realtime functions
    
av_gettime() and av_usleep().
    

    Monotonic support can be added on other platforms with their
    
equivalent native system API eventually if possible.
    

    Whenever time is requested to measure relative time, the monotonic clock,
    
when available, is superior to the system realtime clock because it is
    
not affected by discontinuous jumps in the system time
    

    In a future step, offering the flexibility to let the user choose between
    
rt and monotonic clock for avdevices packets will be investigated.
    

    It is very easy to experience the issues that this patch attempt to address
    
by rewinding back in the past the system time while ffmpeg is running.
    

    this is breaking the ffmpeg report printing (ffmepg.c:print_report()) and
    
the the rate emulator functionality (-re) without the patch.

  • FFMPEG read audio convenience function

    7 mars 2016, par Phlox Midas

    In Matlab, there’s a function called audioread that takes a file name as input and returns a vector of samples and the sample rate like this :

    [samples, sampleRate] = audioread(fileName);

    I’ve been programming FFMPEG but finding it very low level. I have a file being read using a technique similiar to this. Is there any such equivalent C function in FFMPEG as there is in Matlab so I don’t have to fiddle with the low level stuff ? Or any library that can provide a nice API like this for FFMPEG (though I would just prefer this one function) ?

  • External Subtitle Support for FFMPEG

    16 mars 2016, par 123rgt

    Does FFMPEG support external subtitles ?

    In libvlc they have libvlc_video_set_subtitle_file. Does some thing equivalent exist in FFMPEG or can we implement the same using FFMPEG ?

    I need a solution using FFMPEG APIs, not the command line.
