<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">I notice by the way that the file, though it still ends in<br>.mpg, has been turned from an MPEG2 TS into an MPEG2 PS; so<br>
there is some non-trivial processing going on and it isn't<br>just copying bytes from one file to the other except between<br>
the times marked in the cut list, which is what I'd like.</blockquote><br>
As far as I have understood TS and PS, a TS can contain any numbers of
videostreams, audiostreams and other streams (captions, teletext etc)
while a PS can only contain one videostream and one audiostream. In
addition a TS contains synchronization information.<br>
So the TS is larger than the PS and so it is logically to use PS for a file that is intended to be small.<br>
<br>
However I also miss the captions and actually it should be very simple
to make a lossless transcoder from TS to TS as the file has
synchronization markers, so it can simply be cut (and maybe preserve
some header).<br>
<br>
It would also be nice to be able of keeping the captions when
transcoding to MPEG4. DVB-T in Europe has started using MPEG4, so there
must be some kind of support for captions in an MPEG4 file.
Alternatively if the internal player could take the captions from a
separate file, then the captions could be split into a separate file
before the video was transcoded.<br>
