Okay then... I'm using pcm and the sound from fxtv is coming in on line2
(although xmmix tells me it's line1 -- eh?!) so I needed to add this to
TVAUDIOSetMixerMask() (in fxtv's tvaudio.c)
else if ( STREQ( buf, "LINE2" ) ) {
printf("Using Line2\n");
Mixer_dev_id = SOUND_MIXER_LINE2;
Mixer_dev_mask = SOUND_MIXER_LINE2;
Mixer_dev_name = "LINE2";
}
(just stick it in the if statement =) )
This means I can now record sound... Is there any chance we can get all
the mixer devices working properly though, [not sure what would need to be
done for this] - as this hack later whines at me that it can't set LINE2
volume (probably because I'm not using voxware - it does record okay
though!)
Anyway. some thoughts - could fxtv be made to output to a fifo ? (instead
of trying to delete the file straight away!) and would this be useful ?
It doesn't seem too tricky, and as long as I use a little wrapper around
gogo to convert to pcm then use gogo on the sound it's relatively
straightforward..
But .. can we get this happening in real time ? This was why I asked about
a fifo output - gogo seems happy with the input file being a fifo
anyway, and if we could get Fxtv outputting to a fifo it would become
feasible to actually record to mp3 in realtime from the telly.
Then all we need is a super quick video encoder and we're away with some
serious replacement VHS kit on our hands =)
Sorry if I'm rambling a bit much here...
