Need command-line tools that report clip length

[bilu]

Hi,

I need to get clip length from AVI,MP4 and MKV through command-line.

It's a requirement (along with command-line muxers) to integrate support for these containers in my tool.

I already can get clip length from OGM files and that's an essential feature for automatic Vobsub subtitle splitting after muxing and splitting the final encode.

Haven't looked yet for MP4 and MKV files, but I couldn't find anything like this for AVI :confused:


Best regards,

For mkv : mkvinfo, its coming in Mosu's mkvmerge package .... talk to him how you could export the value from the tool, but it should be easy. Or you talk to jccston, he has made a shell extensible for mkv files ...

@bilu What lanuage is your tool in? C++, Delphi, VB?

For AVI you can use a few API calls
Something like this

PAVIFILE pAVIFile;
LPCTSTR szFile;
PAVISTREAM pAVIStream;

AVIFileOpen(pAVIFile, szFile, OF_SHARE_DENY_WRITE, 0&);
AVIFileGetStream(pAVIFile, pAVIStream, streamtypeVIDEO, 0);
numFrames = AVIStreamLength(pAVIStream);

MSDN (http://msdn.microsoft.com/library/en-us/multimed/avifile_3uwj.asp) is a good starting point.

I don't know any program language. Believe it or not, it does a lot just based on command-line tools, batch files and Avisynth scripts! :D

If you look at what my tool and TaZit (a tool from TaZ4hvn mentioned on my thread) do just with batch files and AVS scripts, you'll be impressed! (I hope :D )


Best regards,

I may have missed the point here, but why don't you simply use framecount() and framerate() in avisynth ?

@TaZ4hvn

You made a good point for AVI splitting. Now if I could only do the same over MP4 ... :rolleyes:

Haven't tried Matroska yet.
