>Description:
Due to a bug in mpgtx the code for joining multiple mpeg files does not work when off_t is 64 bit. On FreeBSD, off_t has been a 64 bit value for ages. So, this functionality probably has been broken for a very long time.

A description of the problem along with a patch can be found in the following upstream bug report:
https://sourceforge.net/tracker/index.php?func=detail&aid=1309392&group_id=22678&atid=376136
>How-To-Repeat:
Try joining two mpeg files using mpgtx:

mpgtx -j 1.mpg 2.mpg -o joined.mpg

*** Expected Result ***

Now processing Chunk 1/2 ...  100.00%  
Now processing Chunk 2/2 ...  100.00%  

*** Actual Result ***

failed, range results in an empty chunk
>Fix:
The patch attached to the upstream big report just needs to be dropped into multimedia/mpgtx/files:
