Unresolved symbols when linking ffmpeg 2.7.1 on OSX 10.10.4/amd64 with Xcode 6.4
9 juillet 2015, par Corey BrennerI am seeing a problem linking against ffmpeg 2.7.1 (as installed by homebrew just today). Though the libraries in question are referenced on the command line, and though the linker admits to pulling in the correct libraries, and though the libraries themselves have the desired symbols (verified with NM), the symbols I need from the ffmpeg libraries do not show up.
My host and target platform is Mac x86_64, Xcode 6.4, OS X v10.10.4.
("ERROR (LINK.dll) : " is from my build system)
Thanks in advance !

ffmpeg Progress Bar - Encoding Percentage in PHP
11 juillet 2016, par JimboI’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 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= 117126kBPlease help me output this percentage, once done I can create my own progress bar. Thanks.

Get Proper Progress Updates on Two Long Waited Concurrent Processes in ASP.NET
17 juillet 2012, par irfanmcsdI implemented background video processing using .net ffmpeg wrapper http://www.mediasoftpro.com with progress bar indication to calculate how much video is processed and send information to web page to update progress bar indicator. Its working fine if only single process works at a time, but in case of two concurrent processes (start two video publishing at once let say from two different computers), progress bar suddenly mixed progress status.
Here is my code where i used static objects to properly send information of single instance to progress bar.static string FileName = "grey_03";
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
if (Request.Params["file"] != null)
{
FileName = Request.Params["file"].ToString();
}
}
}
public static double ProgressValue = 0;
public static MediaHandler _mhandler = new MediaHandler();
[WebMethod]
public static string EncodeVideo()
{
// MediaHandler _mhandler = new MediaHandler();
string RootPath = HttpContext.Current.Server.MapPath(HttpContext.Current.Request.ApplicationPath);
_mhandler.FFMPEGPath = HttpContext.Current.Server.MapPath("~\\ffmpeg_july_2012\\bin\\ffmpeg.exe");
_mhandler.InputPath = RootPath + "\\contents\\original";
_mhandler.OutputPath = RootPath + "\\contents\\mp4";
_mhandler.BackgroundProcessing = true;
_mhandler.FileName = "Grey.avi";
_mhandler.OutputFileName =FileName;
string presetpath = RootPath + "\\ffmpeg_july_2012\\presets\\libx264-ipod640.ffpreset";
_mhandler.Parameters = " -b:a 192k -b:v 500k -fpre \"" + presetpath + "\"";
_mhandler.OutputExtension = ".mp4";
_mhandler.VCodec = "libx264";
_mhandler.ACodec = "libvo_aacenc";
_mhandler.Channel = 2;
_mhandler.ProcessMedia();
return _mhandler.vinfo.ErrorCode.ToString();
}
[WebMethod]
public static string GetProgressStatus()
{
return Math.Round(_mhandler.vinfo.ProcessingCompleted, 2).ToString();
// if vinfo.processingcomplete==100, then you can get complete information from vinfo object and store it in database and perform other processing.
}Here is jquery functions responsible for updating progress bar indication after every second etc.
$(function () {
$("#vprocess").on({
click: function (e) {
ProcessEncoding();
var IntervalID = setInterval(function () {
GetProgressValue(IntervalID);
}, 1000);
return false;
}
}, '#btn_process');
});
function GetProgressValue(intervalid) {
$.ajax({
type: "POST",
url: "concurrent_03.aspx/GetProgressStatus",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
// Do something interesting here.
$("#pstats").text(msg.d);
$("#pbar_int_01").attr('style', 'width: ' + msg.d + '%;');
if (msg.d == "100") {
$('#pbar01').removeClass("progress-danger");
$('#pbar01').addClass("progress-success");
if (intervalid != 0) {
clearInterval(intervalid);
}
FetchInfo();
}
}
});
}The problem arises due to static mediahandler object
public static MediaHandler _mhandler = new MediaHandler();I need a way to keep two concurrent processes information separate from each other in order to update progress bar with value exactly belong to that process.
