tlg2300 release notes
|
||||
====================
|
||||
|
||||
This is a v4l2/dvb device driver for the tlg2300 chip.
|
||||
|
||||
|
||||
current status
|
||||
==============
|
||||
|
||||
video
|
||||
- support mmap and read().(no overlay)
|
||||
|
||||
audio
|
||||
- The driver will register a ALSA card for the audio input.
|
||||
|
||||
vbi
|
||||
- Works for almost TV norms.
|
||||
|
||||
dvb-t
|
||||
- works for DVB-T
|
||||
|
||||
FM
|
||||
- Works for radio.
|
||||
|
||||
---------------------------------------------------------------------------
|
||||
TESTED APPLICATIONS:
|
||||
|
||||
-VLC1.0.4 test the video and dvb. The GUI is friendly to use.
|
||||
|
||||
-Mplayer test the video.
|
||||
|
||||
-Mplayer test the FM. The mplayer should be compiled with --enable-radio and
|
||||
--enable-radio-capture.
|
||||
The command runs as this(The alsa audio registers to card 1):
|
||||
#mplayer radio://103.7/capture/ -radio adevice=hw=1,0:arate=48000 \
|
||||
-rawaudio rate=48000:channels=2
|
||||
|
||||
---------------------------------------------------------------------------
|
||||
KNOWN PROBLEMS:
|
||||
|
||||
country code
|
||||
- The firmware of the chip needs the country code to determine
|
||||
the stardards of video and audio when it runs for analog TV or radio.
|
||||
The DVB-T does not need the country code.
|
||||
|
||||
So you must set the country-code correctly. The V4L2 does not have
|
||||
the interface,the driver has to provide a parameter `country_code'.
|
||||
|
||||
You could set the coutry code in two ways, take USA as example
|
||||
(The USA's country code is 1):
|
||||
|
||||
[1] add the following line in /etc/modprobe.conf before you insert the
|
||||
card into USB hub's port :
|
||||
poseidon country_code=1
|
||||
|
||||
[2] You can also modify the parameter at runtime (before you run the
|
||||
application such as VLC)
|
||||
#echo 1 > /sys/module/poseidon/parameter/country_code
|
||||
|
||||
