Problem width ffmpeg version N-60724-gb9936e5 Copyright (c) 2000-2014
Hello everone,
I like to use ffmpeg in my web project to convert video files and get some information from ffmpeg such as duration ,screensize , video bitrate and audio bitrate.
So I downloaded FFMPEG and use this codes in asp.net:
“I have Problem to get above information”
Dim psi As ProcessStartInfo = New ProcessStartInfo("c:\ffmpeg\ffmpeg.exe")
Dim proc As Process = Process.Start(psi)
psi.UseShellExecute = False
psi.Arguments = " -i " & Request.QueryString("file")
psi.RedirectStandardError = True
proc = Process.Start(psi)
proc.WaitForExit()Dim sr As StreamReader = proc.StandardError
Do While Not sr.EndOfStream
Response.Write(sr.ReadLine & "")
Loop
This Codes worked correctly when I used ffmpeg(version N-57235-g0bf8580-Sherpya Copyright developers built on Oct 18 2013 00:18:11 with gcc 4.6 (GCC)) except that it could not convert video files with the format of MKV to MP4. But when I used ffmpeg(version N-60724-gb9936e5 Copyright (c) 2000-2 developers built on Feb 18 2014 22:01:49 with gcc 4.8.2 (GCC)) it converts MKV format to MP4 but it dose not provide duration ,screensize , video bitrate and audio bitrate.
In other words, In FFMPEG (version N-60724-gb9936e5 Copyright (c) 2000-2 developers built on Feb 18 2014 22:01:49 with gcc 4.8.2 (GCC)) , I can Convert video formats but I cann’t get duration and In FFMPEG (version N-57235-g0bf8580-Sherpya Copyright developers built on Oct 18 2013 00:18:11 with gcc 4.6 (GCC)) I can get duration but I cann’t convert video formats (I mean specialy MKV).
So I get this result when I use FFMEG:
In the FFMPEG (version N-60724-gb9936e5 Copyright (c) 2000-2 developers built on Feb 18 2014 22:01:49 with gcc 4.8.2 (GCC)) RedirectStandardError I cann’t find Duration to parse(HOUR , MINUTE , SECOND).

Can you share the complete FFMPEG command, as generated by ASP.NET? That way, we can test it on our versions of FFMPEG. A link to download a sample video might help, too.
Also, if you are running Windows, have you tried the Zeranoe builds of FFMPEG?
