Howdy!
Are there any general recomendations for maintaining 2 V4L devices
(USB camera and BT878 card) for use? Camera and TV use will be sporadic,
but I would hope to have either ready to go at a moments notice.
Things get confused when you load out of order it seems. Am rather
fuzzy on the interaction between Kmod, modules.conf, modules.dep
and launch scripts. Might need to establish one device as /dev/video1
and other as /dev/video2. ( Hmmm, fstab now has its LABELS, maybe we
could use a similar construct for multimedia devices?)
What I have is a BT878, TDA7432, TDA9850, TEA6420 (STB-2), as well
as a Philips (read: Binary only) module.
STB Card (GW OEM) has i2c, sound, tvmixer, TDA7432 and all that.
USB Philips Cam needs a videodev assignment, and usbaudio.
What I usually do:
1) Get kernel source that Agrees with Philips Cam Module availability.
2) compile with BTTV as module, V4L as module, es1371 sound as module,
------- reboot to new kernel -----
3) D/L latest Bttv source, Xawtv source. Compile both.
4) Make ; make install on the bttv (clobbers the stale bttv.o)
5) Compile and install Xawtv.
6) put binary SMP modules from Nemosoft in
/lib/modules/2.4.2/ker/driv/misc
depmod -a ; modprobe difficult ones
Hack and tweak script below till it works, kinda....
Am I approaching this correctly? The v4l devices get mixed up when I
load
stuff out of order...
