I have included a PS recording mode for rtuxview last weekend and
checked it in today. It can't use DVB-T yet, because it's not in the
libdvb, but if you want to include ts2ps into dvbstream, it may be
easier to take it from the dvb_formats.c from tuxzap than to extract
it from mpegtools. Or maybe just link dvb_formats.c to dvbstream. In
mpegtools the stuff is spread over 3 or 4 files.
Since I already have the option to use MPEG audio decoding in
ntuxplayer, or better in dvb_formats.c, I was taking a look at
mpeg2dec and libmpeg2, and saw that it seems really easy to use, so it
may be possible to attach that to rtuxzap as well and you would have a
complete solution for software viewing including remote control and
all. Although, synching may be a problem.
Since I only do this in my free time and when I haven't done enough
programming on the job already, it is progressing slowly.
