Hi.
Please forgive me for my bad english ;)
kernel: 2.6.19.2, ivtv 0.9.1 (0.10rc1),
hardware: Gotview PCI DVD2 Deluxe (Philips MK5)
work: video+audio = ok, radio - errror
1. v4l2-ctl -f 215.250 -s SECAM --verbose
...
ok
2. cat /dev/video0 | mplayer - &
ok.
3. v4l2-ctl -f 135.250 -s PAL
VIDIOC_QUERYCAP: ok
VIDIOC_G_TUNER: ok
VIDIOC_S_FREQUENCY: ok
Frequency set to 2164 (135.250000 MHz)
VIDIOC_S_STD: failed: Device or resource busy
After that I begin to search in v4l2-ctl source this code.
I found tv_set_norm and tv_set_freq (doioctl VIDIOC_S_STD).
Question: how I can change standard from PAL to SECAM if
/dev/video0 busy (cat /dev/video0 | mplayer -) ?
May be deal with stream_pvr?
May be I must stream_pvr close, change standard, and reopen stream?
How I can do this?
Request: may be require to change v4l2-ctl for
make atomic changes (like svn) - or change freq & standard (if I want
this), or don't change freq and standard (if can't change freq OR standard)?
Question for radio:
v4l2-ctl --list-audio-inputs
ioctl: VIDIOC_ENUMAUDIO
Input : 0
Name : Tuner 1
Input : 1
Name : Line In 1
but in source I see some line about radio.
ivtv log in /var/log/messages - ok:
dmesg | grep ivtv
