 Posted: Sun Jun 13, 2004 10:07 am Post subject: PVR 250 & ivtv : cannot tune channels |
 |
|
Hi,
I finally found out how to install & configure ivtv, with the http://wopr.yi.org/mythtv.html guide.
Everything's ok, except that mythtv gives me a blank screen and seems frozen with I try to watch tv. So I decided to try later and to search for the channels myself to watch tv with mplayer /dev/video 
Well, it seems that ptune.pl doesn't change the channels at all (I have the same garbage on all).
Any clue?
I'm using gentoo-dev-sources-2.6.5-r1 and ivtv-0.1.9-r3
In /etc/modules.d/ivtv I have:
| Code: |
# Hauppage PVR 250
alias char-major-81 videodev
alias char-major-81-0 ivtv
option ivtv ivtv_debug=0 mpg_buffers=90
# TUNER_PHILIPS_SECAM
options tuner type=3
# 0x09=france / 0x03=germany / 0x01=auto
options msp3400 once=1 simple=1 standard=0x03 debug=0
add below ivtv msp3400 saa7115 tuner
# IR
alias char-major-61 lirc_i2c
add above ivtv lirc_dev lirc_i2c
|
Besides, I'm not sure of the tuner type and the msp3400 standard, since I'm living at the french-german border and want to get both PAL and SECAM channels.
Despite the add below, the tuner, saa7115 and msp3400 modules are not loaded at boot, so I added the following in /etc/modules.autoload.d/kernel-2.6 :
| Code: |
# PVR-250 Tuner
tuner
msp3400
saa7115
ivtv
|
Here the little script I wrote to scan all channels :
| Code: |
#!/bin/bash
IVTV_DIR="/tmp"
TEST_DIR=$IVTV_DIR/test-`date +"%Y%m%d"`
TEST_DURATION=15
echo "Set capture size to 720x576"
# 1st set to PAL or SECAM (here PAL)
test_ioctl -u 0xff
test_ioctl -p 4
test_ioctl -f width=720,height=576
test_ioctl -v input=2,output=1
# input 3?
for TABLE in pal-europe pal-europe-west secam-france custom ; do
if [ "$TABLE" == "secam-france" ] ; then
echo "Switch tuner to SECAM"
STANDARD=SECAM
test_ioctl -u 0x7f0000 >/dev/null
else
echo "Switch tuner to PAL"
STANDARD=PAL
test_ioctl -u 0xff >/dev/null
fi
for CHANNEL in `ptune.pl --freqtable $TABLE --list-channels | grep = | colrm 5` ; do
echo -n "Test $TABLE channel $CHANNEL..."
ptune.pl --freqtable $TABLE --channel $CHANNEL
if [ -s $TEST_DIR/$TABLE-$CHANNEL.mpg ] ; then
echo "already tested."
continue
elif [ -a $TEST_DIR/$TABLE-$CHANNEL.mpg ] ; then
echo -n "retest."
fi
record-v4l2.pl --duration $TEST_DURATION --standard $STANDARD \
--type mpeg --directory $IVTV_DIR \
--directory-format "test-%d" --date-format "+%Y%m%d" \
--freqtable $TABLE --channel $CHANNEL --inputname 'Tuner 0' \
--input /dev/video0 --width 720 --height 576 \
--output $TABLE-$CHANNEL.mpg --input /dev/video0 >/dev/null
echo
if [ ! -s $TEST_DIR/$TABLE-$CHANNEL.mpg ] ; then
echo "***Error creating file. Reinitialize ivtv:"
echo "# rmmod ivtv msp3400 saa7115 ; sleep 1 ; modprobe msp3400 saa7115 ivtv"
echo "And restart the script that will scan the remaining channels."
exit 1
fi
done
done
echo "Check now in $TEST_DIR which files have video."
exit 0

Damn. I just realized that the tuner and msp3400 options are not used, despite of their presence in /etc/modules.conf
| Code: |
### modules-update: start processing /etc/modules.d/ivtv
# Hauppage PVR 250
alias char-major-81 videodev
alias char-major-81-0 ivtv
option ivtv ivtv_debug=0 mpg_buffers=90
# TUNER_PHILIPS_SECAM
options tuner type=3
# 0x09=france / 0x03=germany / 0x01=auto
options msp3400 once=1 simple=1 standard=0x03 debug=0
add below ivtv msp3400 saa7115 tuner
# IR
alias char-major-61 lirc_i2c
add above ivtv lirc_dev lirc_i2c
### modules-update: end processing /etc/modules.d/ivtv

I had lots of "Jun 13 10:52:07 gentoo kernel: tuner: tuner type not set" in /var/log/messages
I have to load the modules "manually"  :
| Code: |
# insmod /lib/modules/2.6.5-gentoo-r1/kernel/drivers/media/video/tuner.ko type=3
# insmod /lib/modules/2.6.5-gentoo-r1/extra/msp3400.ko once=1 simple=1 standard=0x03 debug=0
# modprobe saa7115
|
Here the /var/log/messages extract:

Is it correct so?
Well, I restart the scan to see if it's tuning now... |

That was is. 
I have now scanned all the channels, but... I have no sound on SECAM channels. Only on PAL ones.
Any clue? |

Clue for future guy having this problem:
load the msp3400.komsp3400.ko module with standard 0x09 (france).
With 0x01 (auto-detect), 1/2 of the channels (random) pal & secam don't have sound.
With 0x03 (germany) near all secam channels don't have sound.
With 0x09 (france), all pal&secam channels have sound.
# insmod /lib/modules/<your kernel version>/extra/msp3400.ko once=1 simple=1 standard=0x09 debug=0 |
