OK, I have been playing around more with this and have the following
observations (and if you are all tired of hearing about this; well so am
I :) ):
The zoran driver in 2.4.21 works to grab images, but is ancient, and
does not support using highmen at all. It will allow me to grab
compressed images, or small uncompressed images, but not large
uncompressed ones.
So that leaves the 0.9.4 driver. I have now tested the following:
* Clean installation of 2.4.21 on rh9. Unpack, make and make install the
0.9.4 driver (I get a warning about /scripts/pathdown.sh not being
available, and some warnings about using a hack, but compiles cleanly
otherwise). I edit the update script to comment out some lines as
directed. I load the driver by running ./update lml33
* Running either lavrec (to capture compressed frames), xawtv induced to
do software rendering (no Xv), or my own code will result in everything
seeming to work (no dmesg errors or anything). I can see with dmesg that
it does the appropriate ioctls to queue and grab frames.
* No frames are, however, grabbed by the driver. Instead, it returns a
solid block of a buffer (I don't know if it's actively set by the
driver, but I suspect it is, as it isn't black, but blue (for lavrec) or
red (for me)).
If I unload these drivers and load the old driver included in 2.4.21, I
will get captured frames, so it isn't a hardware problem.
So, the question is, what am I doing wrong?
Spec:
2.4.21 built and installed on rh9
lml33 cards, two of them, and both attached to confirmed working
cameras.
the 0.9.4 drivers, built and installed as per instructions
If anyone uses the 0.9.4 drivers with lml33 cards, I would be very
grateful to get _any_ information on how you set it up and got it to
work, especially on rh9 and/or using the 2.4.21 kernel.
