Hi,
Many thanks for all the good advice on ivtv.
Using
/usr/bin/v4l2-ctl -n
and testing the various values of n in
/usr/bin/v4l2-ctl -i n
eventually got video capture working.
Now that I can capture and view video, it'd be great to hear the
accompanying sound :) ... right now all I get is silence.
How do I get captured audio with the video?
When I connect the VCR audio out to the Hauppauge 250 audio in,
I get only silence.
When I connect the VCR to the PC sound card instead of the Hauppauge 250,
I can hear the audio, so at least the VCR and cable are ok.
I've tried ...
# List audio inputs:
$ /usr/bin/v4l2-ctl -q
ioctl: VIDIOC_ENUMAUDIO
Input : 0
Name : Tuner 1
Input : 1
Name : Line In 1
Input : 2
Name : Line In 2
# Try each audio input in turn:
$ /usr/bin/v4l2-ctl -a 0
$ /usr/bin/v4l2-ctl -a 1
$ /usr/bin/v4l2-ctl -a 2
But none of these result in audio.
I've tried mplayer with
-ao alsa
and
-ao oss
but neither works. mplayer seems to be finding a sound
channel, and it's output is below.
Many thanks,
Steve
