Amancio Hasty:
|Feel free to try out my latest beta on my ftp site:

|That release makes the correct decision in set_fps for PAL or NTSC.
Well, neither single field or full field works for me with this
version. Testing by flipping an ioctl(SFPS, 1) into fxtv, for single field
(ODD_ONLY) CAP_CONTINUOUS, I get a frame every 1 to 3 seconds, and in
between the updates, trash corrupts the image (see:
http://multiverse.com/~rhh/tmpimages/bt848-970524-prob1.gif
for a snap).
For interlaced images, I get 1 or 2 single-field (not frame) updates
every 1 to 30 seconds, with less image trash but still some corruption
gradually appearing between field appearances.
Also, as an aside, CAP_SINGLEs rarely work since temporal decimation
isn't being turned off for CAP_SINGLE requests and turned on for
CAP_CONTINUOUS, but rather is always left on. This was one of the fixes in
the patch I posted. A simple mod.
In case it helps, here is some debug driver output for single and
double frame continuous-capture generated with ioctl(SFPS,1) and the 970526
driver off rah.
Thanks,
Randall
