Hi,
today I got ITE Technologies, Inc. DVB-T TV Stick and would like to use
it under FreeBSD. As I did not try anything like this before, I would
like some help here. First what I did...
Some product info is on http://www.notonlytv.net/p_lv52t.html - not
much, as usual.
Device presents itself in dmesg/console after connecting like this:
ugen4.3: <ITE Technologies, Inc.> at usbus4
uhid0: <ITE Technologies, Inc. DVB-T TV Stick, class 0/0, rev
2.00/2.00, addr 3> on usbus4
usbconfig dump_device_desc for ugen4.3 writes
ugen4.3: <DVB-T TV Stick ITE Technologies, Inc.> at usbus4, cfg=0
md=HOST spd=HIGH (480Mbps) pwr=ON (500mA)
bLength = 0x0012
bDescriptorType = 0x0001
bcdUSB = 0x0200
bDeviceClass = 0x0000
bDeviceSubClass = 0x0000
bDeviceProtocol = 0x0000
bMaxPacketSize0 = 0x0040
idVendor = 0x048d
idProduct = 0x9006
bcdDevice = 0x0200
iManufacturer = 0x0001 <ITE Technologies, Inc.>
iProduct = 0x0002 <DVB-T TV Stick>
iSerialNumber = 0x0000 <no string>
bNumConfigurations = 0x0001
so I googled for vendor 048d and product 9006. I found some interesting
pages, first one is https://linuxtv.org/patch/8794/ - which told me the
device is known and could be used, at least in linux. Then I came to
http://www.abclinuxu.cz/poradna/hardware/show/351331 - in Czech,
interesting link there points to some source somehow dug from producer -
http://www.abclinuxu.cz/data/prilohy/1/0/183701-it9135_src-tar-8535350393703910459.bz2
- I have no idea what to do with this, but maybe someone has. Page
http://www.linuxtv.org/wiki/index.php/ITE_IT9135 show how to get
firmware for this device. It will be used later.
As I already have webcamd installed, I just tried run webcamd and got
it:
# kldload cuse4bd
# webcamd
Attached to ugen4.3[0]
Loading firmware at '/boot/modules/dvb-usb-it9135-01.fw', f=7
Creating /dev/dvb/adapter0/demux0

Creating /dev/dvb/adapter0/dvr0
Creating /dev/dvb/adapter1/dvr0

Creating /dev/dvb/adapter1/frontend0
Firmware obtained before was put into /boot/modules and some devices
were presented. Now the question is, how could I use it. Some time ago
I did some test with simple webcam, where I could use pwcview to see
image from camera, however it is of no use here, I got just
% pwcview -d /dev/dvb/adapter0/frontend0
Failed to get current picture info: Device not configured
% pwcview -d /dev/dvb/adapter0/demux0
Failed to get current picture info: Invalid argument
% pwcview -d /dev/dvb/adapter0/dvr0
Failed to get current picture info: Invalid argument
so something else should be used.
And here comes the question - are those devices presented via webcamd
enough or do I need something more? Which application is the simplest
one for first test? I think I need some player application to watch
video and something to select stream to watch. Also there is a
remote, /dev/uhid0 is created when connected to USB port so it should
be usable too.
I am trying to get some info from https://wiki.freebsd.org/WebcamCompat
even if this device is not (yet) mentioned here, and
https://wiki.freebsd.org/VDR too, maybe this is not the simplest
application but nevertheless...
Any help here is appreciated.
Regards,
Milan
