  • PHP Ajax XMLHttpRequest popen live progress

    21 février 2016, par John R

    I’m trying to output live : the ffmpeg progress

    It works great when I execute the php file alone : many lines with text appearing one after an other...

    ••• But when it’s a XMLHttpRequest context, the output is 1 line empty

    PHP working when not in AJAX situation :

    ini_set("output_buffering", "0");
    
ob_implicit_flush(true);
    
$call_mp4 = ' __FFMPEG Command HERE__ ';
    
$proc = popen($call_mp4, 'r');
    
while (!feof($proc)) {
    
    echo '['.date("i:s")."] ".fread($proc, 4096).'<br />';ob_flush();flush();
    
}

    Does someone know why in AJAX it’s blank and only 1 line ?
    how can this be fixed ?

    Regards

  • Downloading earlier segments from a live m3u8 playlist

    25 juillet 2016, par Zafer Cesur

    I have an .m3u8 URI from an online live-stream. As far as I know, live playlists use a sliding window instead of containing all the segments. My questions are,

    1) Is it possible to find out what the length of the window is (time or frame-wise) ? My intention is to use the playlist I have to download a live-stream starting from an earlier time.

    2) If yes, how do I get the earlier segments, i.e., how do I specify where I want to start downloading from ? I tried something like ffmpeg -ss -00:00:10 -i "in.m3u8" out.mp4, but it did not work.

    I do not have much experience in video-encoding or live-streaming, and I would appreciate any direction ! The file that I am dealing with is printed below.

  • 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.

    Duncan
