Thanx for your answers, but I'm afraid, there's more to it than simply
putting the real pid-values into ts2ps.
I've tried that several times using the vpid and apid values, tuxzap
shows in the channel list if you drill down the channel properties. It
simply doesn't change a thing...
Perhaps it even makes it worse! Today I found out by chance, that a stream is
coming through ts2ps using pid auto-detection. But it takes about 2 - 5
minutes time, till mplayer recognizes a mpeg-stream and displays the
picture.
Before I began writing this mail, I started
"ts2ps /dev/ost/dvr 101 102 | buffer | mplayer -"
but up to right now (approx. 10 minutes later), no stream is available
to mplayer so I guess it won't come anymore. So I think, using pid 0 0
works even better then specifying the real ones.
Apart from that start delay the result in mplayer is far from being
satisfactory. For further information I quoted the xterm-output from
stvmp (script from PSIplus) below.
Picture quality is good, but mplayer can't detect any
sound in the stream. Maybe this is a result of the fact, that vPID and
aPID are identical. Also the video-stream suddenly ends after a few
minutes and mplayer stops, saying "(End of file)". In most cases, the
startup-delay is longer than the picture is shown. If you're lucky you
can view a commercial spot in a whole but nothing much longer.
Any ideas?
