Use ffmpeg to extract picture from m4v file
31 octobre 2017, par BrianI used a program called MetaZ on my mac to tag all my video files (m4v). I am now trying to use these m4v files in Kodi which requires .nfo files and separate picture files for movie posters, etc. I want to extract the picture that is already in the m4v file.
When I use ffprobe -show_streams, I can see that index4 is a png file (codec_name=png). How do I extract it ? I believe ffmpeg can do it, but can’t figure out how.
Here is the output from ffprobe :

Convert static file to h264 stream with FFmpeg [on hold]
28 août 2013, par VprnlI'm building a NodeJS application that converts a static videofile to a streamable video which is being sent to a client (iPad or browser) on the fly (using the fluent-ffmpeg module).
Everything is set and all I need now is to configure ffmpeg correctly. But I'm having a lot of problems with ffmpeg.
With my current settings, I hear audio right away, but the picture starts a couple of seconds later. Then, my 30 second test file has been compressed to 3 seconds of high speed imagery.
How can I configure my ffmpeg so it will stream the mp4 correctly (in one pass through of course). It seems it is streaming raw h264, if that is the case how can I force the mp4 container. I thought I was doing that by using '-f mp4'
my correct settings are :
'-crf 22','-c:v libx264','-f mp4','-movflags','faststart+frag_keyframe'
I've also tried :
'-r 30','-crf 30','-analyzeduration 0','-probesize 1000','-rc_lookahead 0','-fflags nobuffer','-g 75','-ss 0','-threads 0','-vcodec libx264','-qcomp 0.6','-qmin 10','-qmax 51','-qdiff 4','-b:v 400k','-maxrate 400k','-bufsize 800k','-acodec mp3','-ab 192k','-ar 44100','-tune zerolatency','-f mp4','-movflags','faststart+frag_keyframe'
As you can see by the amount of options I've tried, I'm getting pretty desperate. I'm basically just running around in the dark.
I don't think it matters much but these are my request headers :
res.writeHead(200, { // NOTE: a partial http response
'Content-Type':'video/mp4',
'Content-Length':stat.size,
'Content-Range':'bytes '+start+'-'+end+'/'+stat.size,
'Transfer-Encoding':'chunked'
}); -
How to get the video duration using FFMPEG in C# asp.net
23 août 2013, par HamadI want to get the video file duration in string using C#. I searched the internet and all i get is :
ffmpeg -i inputfile.avi
And every1 say that parse the output for duration.
Here is my code which is
string filargs = "-y -i " + inputavi + " -ar 22050 " + outputflv;
Process proc;
proc = new Process();
proc.StartInfo.FileName = spath;
proc.StartInfo.Arguments = filargs;
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.CreateNoWindow = false;
proc.StartInfo.RedirectStandardOutput = false;
try
{
proc.Start();
}
catch (Exception ex)
{
Response.Write(ex.Message);
}
try
{
proc.WaitForExit(50 * 1000);
}
catch (Exception ex)
{ }
finally
{
proc.Close();
}Now please tell me how can i save the output string and parse it for the video duration.
Thanks and regards,
