Hi Rob,
Hi. :)
How's your system recovery going?
Almost done... I am so tired. Everything is almost setup again but I am having a stupid audio problem. My audio drivers (trident, ac97) load fine, I get a device, adio apps run fine like there is nothing wrong but I get no sound!! There are no muted channels. I tried alsa but things kept segfaulting. Any suggestions?
I tried the new runtime-pre5-test1 mplayer and found that it didn't do anything with the forceaudio option for tv parameters, needed to get my v4l2 card working properly with mplayer. The mplayer startup message still says "Audio: no sound". I'm not sure if 'forceaudio' is supposed to provide some other display message?
BTW, I added freevo_python to that runtime tarball but I am going to add tvtime before uploading it to the website again.
(BTW, the new mplayer now requires input URL as tv:// instead of passing 'on' as part of the tv parameters -- I hope that freevo mplayer script was modified to reflect this).
I'll have to check that.
Here's my mplayer call parameters (in case I forgot something): ./apps/mplayer/mplayer -fps 30 -tv \ driver:v4l:forceaudio:forcechan=1:amode=0:adevice=/dev/dsp:\ device=/dev/video0:channel=E5:norm=pal:chanlist=europe-west:\ width=720:height=576 -ao alsa9 -vo fbdev tv://
The patch which is supposed to allow v4l2 cards to function with mplayer is below. Can you please verify that it's already part of the mplayer cvs snapshot?
I'll check that too. Thanks for the heads-up.

Rob,
Since you'll be building a new runtime, can you please make sure that the following mplayer patch has been applied (it's supposed to be in the latest mplayer CVS). This is to fix the issue of no audio unmuting during TV playback on v4l2-only devices (e.g., saa7134 TV cards).
To use this feature, the tv parameters have to include 'forceaudio'. I don't think the tvcmd tv parameters in src/tv/mplayer.py can be overridden via local_config.py yet.
Also, the tvcmd for vcr mode hardcodes chanlist=us-cable. Can it use the same format as for TV viewing where chanlist is a variable which takes its value from freevo.conf?
Thanks. T.C.
