Of course :)
First off, have you got dvbtune / dvbstream from CVS, or are you working from
the downloadable ones in a tarball?
You need to be using the CVS ones - let me know if you need directions to get
these! :)
For BBC / Freeview muxes:
dvbstream -f 754167 -qam 16 -cr 3_4 -ps 600 601 -o | mplayer - -nocache
-f -> set frequency to 754167000 Hz
-qam -> set Quadrature Amplitude Modulation - defines how tightly packed the
data in the transmitted stream is. Higher value means more data, but higher
risk of corruption due to atmospheric conditions.
-cr -> set error-correction ... defines how much of the stream will be
redundant data used to keep the stream valid.
-ps create a Program Stream instead of a Transport Stream
A Program Stream is the proper name for an "mpeg video" on the Internet, or a
'VCD' .. it contains one video stream and one audio stream, together with
some information for a player to syncronise the two.
-o means send the output to stdout rather than multicasting it over a network.
Let me know if I can be of help - it took me ages to get the hang of this
stuff initially, and I'd like to share the information with others =)
