So the audio was muted then.

Sorry I meant after you set up VLC to play the video :-[

Ok It's back to giving me no video again, like I said in a previous post I never done anything to get it working in the first place so this doesn't surprise me,  But here's the output you asked for anyway incase it gives you any clue why it's so fragile


Code: [Select]
=-1 :v4l2-backlight-compensation=-1 :v4l2-band-stop-filter=-1 :no-v4l2-hflip :no-v4l2-vflip :v4l2-rotate=-1 :v4l2-color-killer=-1 :v4l2-color-effect=-1 :v4l2-audio-volume=-1 :v4l2-audio-balance=-1 :no-v4l2-audio-mute :v4l2-audio-bass=-1 :v4l2-audio-treble=-1 :no-v4l2-audio-loudness :v4l2-set-ctrls= :live-caching=300

Many thanks

Thanks, but that line is not complete.

In VLC Go to:
Media>Capture Device>Advanced Options:
       >Frequency <input number part of saved frequency for betamax>
Then press OK

Post the Edit line
Try to see if you get picture

At the moment I'm working on VHS the old Betamax started eating tape to add insult to injury, I assumed for the purpose of getting this working it wouldn't matter what machine I was using, I hope my assumption hasn't caused any problems if it has I apologise

 
Code: [Select]

I notice tuner frequency is listed as 1 but under advanced options it's listed as -1, don't know if that means anything

Many thanks

Nope, it does not matter which video you are using for the input
Could you change the tuner frequency to match the previously recorded frequency for the VHS
then try again to see if you get a picture.

Code: [Select]
VHS Frequency
graeme@Linux1 ~ $ v4l2-ctl --get-freq
Frequency: 12532 (783.250000 MHz)
graeme@Linux1 ~ $

I tried changing tuner frequency to 12532 that didn't work then I tried 783,250000 but it wouldn't allow me to enter that I then tried reducing the integar to 783.25 but it wouldn't let me enter that either

SeZ o I really feel I'm being a royal PITA with this now and I feel I'm just pestering you, honestly if want to tell me this can't be done with this hardware I'll accept that look for other hardware to do the job, you've give this everything and I appreciate all your effort I really do, I'll go on as long as you and Mark are prepared to, but please don't think I'll be offended or disappointed if you think I should give up

I don't know if this helps, but here goes

if I try to load the movie in VLC I get no audio or video, however if I load xawtv and tune in to channel 60 I get audio & video but will not record , if I then close out of xawtv and open VLC it will load video only and it will record (no audio) (in other words VLC will only play video if the signal has previously been tuned in by xawtv) if I reboot the PC I have to go through the same procedure again, so it seems it's a frequency problem with VLC and once xawtv tunes the card in VLC will play, the same happens with Cheese so to summarize

xawtv will play audio & video but will not record (but doesn't crash)
Cheese will play video only but crashes when I try to record
VLC will play & record video only (no audio)

It is up to you if you want to give up.
it seems that the stumbling block is getting stable (reliable) channel tuning set up which works every time
You could try to input in VLC for frequency 783250 and see if that gives the right channell

Alternatively (before you start VLC):
Code: [Select]
v4l2-ctl -d /dev/video0 -f 783.250
and as a test run:
Now test it works:
Code: [Select]
mplayer /dev/video0

You should now see the video on the PC screen corresponding to the input of the card.
Enter 'q' to quit mplayer

To record it as a file issue the command:

Code: [Select]
mplayer -dumpstream -dumpfile capture.mpg /dev/video0
Press ctrlc-c to quit when you are finished

I don't really want to give up I just don't want to be a pest that's all

Anyway I rebooted the PC and ran your command (v4l2-ctl -d /dev/video0 -f 783.250) and that worked perfectly although still no audio


Code: [Select]
mplayer /dev/video0

gives this output 


Code: [Select]
graeme@Linux1 ~ $ mplayer /dev/video0

I'm still wondering if using Ubuntu 12.04/Mint 13 with the older gstreamer might help.
(or even Peppermint 3, if we can get cheese installed and working)

Lot of work, I know .. but I still think this is sommat to do with gstreamer 1.0

I have no idea Mark I lost track of this 7 pages ago, I know this is unrelated but I remember having a problem with gstreamer playing mp3's when I first installed peppermint 3 and you helped me sort it out, strangely enough VLC supplied the solution.

I don't know what's wrong with Cheese in peppermint I'm sure it did work, I've tried re-installing but that didn't help, but I haven't tried opening Cheese from the terminal to see if there is an error reported that could give me a clue (not that any of the error descriptions mean a lot to me).

Anyway I'm never gonna find the solution myself so I'm relying on you and Sezo to find one for me (which I know you will given time) so I'll follow whatever you both think is the best path to take, if you want to move this to peppermint that's what I'll do


Many thanks

In Mint .. can you post the output from:
Code: [Select]
lsmod
and
Code: [Select]
cat /proc/asound/pcm



At some point it might be worth finding out if there's any output from:
Code: [Select]
cheese
in Peppermint ;)
