Slicing MPEG Files by Play Time Ranges with mpgtx

This section provides a tutorial on how to slice a MPEG file with a given play time range.

The slice function of "mpgtx" allows you to slice out a chunk of the media data with a given play time range or offset data size range. The slice function requires the following command arguments:

• "-s file.mpg [hh:mm:ss-hh:mm:ss]": The slice command option with the input MPEG file and the slice range.
• "-b base_name": The output file name base.

Here is an example of slicing a MPEG-1 file to get only 10 seconds of play media data betwen 10 and 20 play seconds:

C:\temp>\local\bin\mpgtx -s sample_full.m1s [00:00:10-00:00:20] 
   -b sample_part

Now processing sample_full.m1s [1/1] ...  100.00%

C:\temp>dir sample*.*

   4,913,152 sample_full.m1s
   1,739,330 sample_part.mpg

Test the output file sample_part.mpg with MPlayer. It plays nicely.
