Re: how does v4l2 driver communicate a frequency lock to mythtv
Thanks a lot for your advice! I will look into the g_tuner and signal function.

Re: how does v4l2 driver communicate a frequency lock to mythtv
Hi Devin, I have introduced t-signal = 0x; /* LOCKED */ on tm6000-video.c(vidioc_g_tuner) and mythtv indeed can locked the channel. xc2028_signal is showing the correct signal strength information. How can i call get_rf_strength to set the t-signal from vidioc_g_tuner? thanks, Hock.
