    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • ffmpeg - Encoding Percentage in PHP

    13 juillet 2012, par Jimbo

    I've written a whole system in PHP and bash on the server to convert and stream videos in HTML5 on my VPS. The conversion is done by ffmpeg in the background and the contents is output to block.txt.

    Having looked at the following posts :

    Can ffmpeg show a progress bar ?

    and

    ffmpeg video encoding progress bar

    amongst others, I can't find a working example.

    I have always struggled with the regexes and maths, and I need to grab the currently encoded progress as a percentage.

    The first post I linked above gives :

    $log = @file_get_contents('block.txt');
    

    
preg_match("/Duration:([^,]+)/", $log, $matches);
    
list($hours,$minutes,$seconds,$mili) = split(":",$matches[1]);
    
$seconds = (($hours * 3600) + ($minutes * 60) + $seconds);
    
$seconds = round($seconds);
    

    
$page = join("",file("$txt"));
    
$kw = explode("time=", $page);
    
$last = array_pop($kw);
    
$values = explode(' ', $last);
    
$curTime = round($values[0]);
    
$percent_extracted = round((($curTime * 100)/($seconds)));
    

    
echo $percent_extracted;

    The $percent_extracted variable echoes zero, and as maths is not my strong point, I really don't know how to progress here.

    Here's one line from the ffmpeg output from block.txt (if it's helpful)

    time=00:19:25.16 bitrate= 823.0kbits/s frame=27963 fps= 7 q=0.0 size=
    117085kB time=00:19:25.33 bitrate= 823.1kbits/s frame=27967 fps= 7
    q=0.0 size= 117085kB time=00:19:25.49 bitrate= 823.0kbits/s
    frame=27971 fps= 7 q=0.0 size= 117126kB

    Please help me output this percentage, once done I can create my own progress bar. Thanks.

  • lavfi/drawutils : improve colorspace support

    lavfi/drawutils : improve colorspace support

    - Introduce ff_draw_init2, which takes explicit colorspace and range
    
  args

    - Use lavu/csp and lavfi/colorspace for conversion, rather than the
    
  lavu/colorspace.h macros

    - Use the passed-in colorspace when performing RGB->YUV conversions
    

    The upshot of this is :

    - Support for YUV spaces other than BT601

    - Better rounding for all conversions

    - Particular rounding improvements in >8-bit formats, which previously
    
  used simple left-shifts

    - Support for limited-range RGB

    - Support for full-range YUV in non-J pixfmts
    

    Due to the rounding improvements, this results in a large number of
    
minor changes to FATE tests.
