Hi Steve,
|
|
<BR>
|
|
the debugging is going quite well, I would like you to take a look at the
|
|
<BR>
|
|
attached logs and see if you can remember what the intent of the calcs were
|
|
<BR>
|
|
in RGBRouter_remaining() in file backend/snapscan-sources.c.
|
|
<BR>
|
|
If the hanging problem caused by bad return values from this routine gets
|
|
<BR>
|
|
fixed, I think things will run quite well... I have done quite a few scans
|
|
<BR>
|
|
with the previous fix for the EAGAIN problem and that seems to work.
|
|
<BR>
|
|
I am pretty sure the problem is caused when the circular buffer used for
|
|
<BR>
|
|
aligning the RGB data gets bigger than the input data structure... this
|
|
<BR>
|
|
should not matter, but obviously some different calcs are needed in the
|
|
<BR>
|
|
RGBRouter_remaining code.... maybe just limits???
|
|
