Well, again, from very beginning. :)
My program captures the MPEG Transport Stream from a DVB-S card. It works under
MS Windows and uses the card's specific API. I cannot open this stream with
ffmpeg.exe (command line utility) directly.
I can either dump the stream to a file and open this with ffmpeg -i, or define
ByteIOContext and use libav* functions.
I post the output of ffmpeg on the stream dump below, as it is rather long.
Using ffmpeg, I save the parts of the stream to files. For example, one user
defined video stream from a user defined program and one accompanying audio
stream.
The file p8211<etc>.mpg is one of such files. It is the output of my program.
It stores the program 8211, pids 2221 (0x08AD) and 2231 (0x08b7)

The result of ffmpeg -i <input for my program> is given below at the bottom of
my message.
Now, file p8211_2221_2231_2008-04-04-14-25-00_2008-04-04-14-35-00.mpg is the
*output* for my program
Here it is.
$ ffmpeg -i p8211_2221_2231_2008-04-04-14-25-00_2008-04-04-14-35-00.mpg

Unfortunately, I cannot store the original transport stream during the
recording (the computer runs out of resources).
VLC (0.8.6c) displays two different numbers, but they are the same for both
files (p8211_2221_2231_2008-04-04-14-25-00_2008-04-04-14-35-00.mpg, written
with my program, and p8.mpg, written with ffmpeg after processing
p8211<etc>.mpg)
It shows 0:00:04 in the lower left corner of the video window, and 0:10:00 in
View->Stream and media info->Advanced information.
VLC (0.8.6a) displays 4sec everywhere.
Kaffeine also shows 4 sec for both files.
