I hadn't heard back on my prior posting and had found some more docs that
lead me to what I thought would fix things, but didn't.
I edited /etc/security/console.perms so that the line for v4l reads as
<console> 0666 <v4l> 0766 root.video
Rather then the previous way:
<console> 0600 <v4l> 0600 root
This has changed the perms on all devices that v4l is to control being /dev/
dsp* /dev/video* /dev/vpi* etc...
Or so I thought?
Looking at the header info on that file:
<v4l>=/dev/video* /dev/radio* /dev/winradio* /dev/vtx* /dev/vbi* \
I am still getting errors when attempting to do a cat /dev/video0 > temp.mpg
I actually had this working at one point, and mythtv still wouldn't play
Then after a reboot the output of lspci changed so that the modules were in
a different location than where they were for the past week. Meaning that
they listed at the top rather than at the bottom of the output. I don't
think that matters, however the cat test now fails.
Previously I couldn't get aplay /dev/dsp to work with line muted and got
that fixed per a great tutorial on the myth-wiki:
Even though I am not using the same sound card, the directives in his
example appear to be generic with the comments being specific to the make
and model of sound card. The sound is now digitizing as it should be with
really good quality. This seems to be another issue with the flyvideo2000
cards per my searches for help.
I have read every doc that I could find over the past week and there is no
feedback to help with these issues and folks that don't have hardware
decoders. There is lots of info for those with the hauppauge pvr-350 and
I am looking forward to some feedback as to how to hearing back with some
more info on managing /dev/video0 and other v4l devices. I figure this is a
good question for the v4l folks, yet also figure we here are dealing with
this more then any other group of people? If I don't hear back this time I
will post there. I don't want to cross-post and hoped that the myth group
would be the place to find these answers
Thanks in advance,
