Hi!
Post by Hans Petter SelaskyPost by christophe LE ROUXAs i can read on some web pages, webcamd can support webcam and dvb-t
devices who have a linux driver.
What about dvb-s (or dvbs2) usb devices ?
Yes, many are supported, but some are not. Please see the main Makefile in
webcamd.
Post by christophe LE ROUXi think about Tevii S650 ( or S660 ) with ds3000.c linux driver, Pinacle
PCTV 452e Sat HDTV Pro USB with pctv452e.c linux driver or Technotrend
Connect S2-3600 HDTV-S2 USB ( with pctv452e.c linux driver too ).
Another question,
If webcamd can support these usb devices, can i use mythtv port with ?
I have not tried this yet. If mythtv uses the linux DVB header files, then
yes.
For the OP (and other readers:) I haven't tried mythtv yet but after
some hacking and a longer debugging session on #bsdusb I got a PCTV 452e
Sat HDTV Pro USB working using szap-s2,
http://www.linuxtv.org/wiki/index.php/Szap-s2
checked out from hg and built by:
gmake INCLUDE=-I/usr/local/include
and the CFT mplayer port (looks like it still isn't committed),
http://lists.freebsd.org/pipermail/freebsd-multimedia/2010-January/010784.html
pointed at the dvr0 device:
mplayer -demuxer lavf -cache 8192 /dev/dvb/adapter0/dvr0
kaffeine worked too but the version in ports doesn't yet know dvb-s2,
(and even on Linux where I have a newer kaffeine it still has audio
issues on the hd channels.) vlc's builtin dvb support was useless with
this tuner (and caused us lots of useless debugging looking for a problem
in webcamd because vlc behaved like it got a corrupted stream...),
what does `work' is pointing vlc at /dev/dvb/adapter0/dvr0 together
with szap-s2 like mplayer, but vlc used too much cpu on hd channels so
they weren't really watchable. (unlike mplayer which played 1080i
just fine using ~85% of one core and only xv on xorg's radeon driver
on a PhenomII cpu...)
About szap-s2: I ran it similar to this:
./szap-s2 -V -n 6 -p -t
and on some hd channels I need -b too or mplayer would get no audio.
-t is a new option I just added to pass teletext thru (vlc can display
it, this needs -V because the teletext pid is only in the VDR channel.conf
format), that patch I put here:
http://people.freebsd.org/~nox/szap-s2-teletext.patch
hps now has updated the webcamd svn to use only the pctv452e driver
out of the s2-liplianin repo that I originally used entirely in place
of the linuxtv.org one (for some reason the pctv452e-related drivers
are still missing in upstream Linux) and I just tested that svn version
today:
http://www.selasky.org/hans_petter/video4bsd/
I haven't tried building w_scan on FreeBSD yet
http://www.linuxtv.org/wiki/index.php/W_scan
but hps said he only needed to fix include paths - you need it if you
don't have a channels.conf yet, I took mine from Linux with some
updates off the web. kaffeine can scan too, but as I said this
version doesn't know dvb-s2, and also it uses its own channel list
format.
Oh and a poor man's way of recording is to use szap-s2 and then
cat /dev/dvb/adapter0/dvr0 to a file... (you probably can play it
with mplayer while it's still being written if you wait a little
at first if you want to find out when the show you want ends.)
And finally a note about the Tevii s660 tuner: That one was
what I tried first, but even after putting the second pci usb
controller in it only worked on Linux, on FreeBSD I only got this:
(after enabling printk and friends in webcamd)
Invalid probe, probably not a DS3000
.and the pci usb controllers were because when I first tried
the Tevii on Linux it hung Linux' usb stack and of course wouldn't
work at all (causing even `lsusb' to get stuck until I unplugged the
tuner), and then I read on the web that people had success by putting
the Tevii on another usb controller - I still had a pci card lying
around so I tried that, which fixed the lsusb hangs and got dvb-s
channels working - but dvb-s2 channels still only got a corrupted
stream and FreeBSD got the above message. Got another pci usb card,
that fixed dvb-s2 on Linux, but FreeBSD was still broken - and so I
got the pctv and checked out s2-liplianin...
Cheers,
