[linux-dvb] Re: [PATCH] azap (ATSC Zapping Application) + channels.confexample
Taylor Jacob wrote:
Attached is a patch to include zap capabilities for ATSC cards. I also included
a channels.conf example file for my local area to help get some people started.
It's mostly a hack up of tzap but serves the purpose.
I was given a script by Angel Li in Miami who has one of the nxt2002 based cards
that generates a azap channels.conf file from antennaweb.org based solely on a
zipcode which makes setup quite easy for ATSC users. It that something that
could be added someplace in cvs as well?
Taylor
I attached a patch for mplayer-cvs: it should permit to tune atsc
channels with the dvb:// syntax.
The channels.conf file it searches is ~/.mplayer/channels.conf.atsc.
I would be grateful if someone would test the code (I can't: not ATSC in
italy).
Thanks,
Nico
