Hi Hans,
I got the permission to relicense the JPEG Lite decoding to the LGPL.
Ah, good, patch applied and pushed to git.
If you want to test the nw80x driver, get the gspca tarball from my web
page (2.12.12). I added your webcam which should directly work (p35u -
chip nw801).
I've tested it and it works :) I also tested the JPGL -> YUV path.
I did find 2 bugs, the "if (gspca_dev->curr_mode)" test in sd_start,
needs to be inverted. In general it is a good idea to do a test
on gspca_dev->width, rather then curr_mode IMHO, it is more
readable and less error prone.
Talking about readability, I also found the
if (sd->bridge == BRIDGE_NW800) {
...
} else {
...
if (sd->bridge == BRIDGE_NW802) {
...
} else {
...
}
}
part in sd_init a bit hard to grok, can this be changed
to a switch case on sd->bridge ?
The other bug was a divide by zero -> kernel panic, in
do_autogain when sd->ae_res == 0, note this was when I was
messing around with the driver a bit (before I found the
issue with the inverted curr_mode check), but I think this
could happen in real life to depending on register values
and we should protect against this.
Regards,
Hans
