submitted ioctl to clear the video buffer
prior to starting video capture
Amancio : clean up yuv12 so that it does not
affect rgb capture. Basically, fxtv after
capturing in yuv12 mode , switching to rgb
would cause the video capture to be too bright.
1.32 disable inverse gamma function for rgb and yuv
capture. fixed meteor brightness ioctl it now
converts the brightness value from unsigned to
signed.
1.33 added sysctl: hw.bt848.tuner, hw.bt848.reverse_mute,
hw.bt848.card
card takes a value from 0 to bt848_max_card
tuner takes a value from 0 to bt848_max_tuner
reverse_mute : 0 no effect, 1 reverse tuner
mute function some tuners are wired reversed :(
1. Takeshi Ohashi <ohashi@atohasi.mickey.ai.kyutech.ac.jp> submitted
code to support bktr_read . /usr/src/share/examples/rgb24.c now works 8)
2. Flemming Jacobsen <fj@schizo.dk.tfs.com> submitted code to support
radio available with in some bt848 based cards;additionally, wrote
code to correctly recognized his bt848 card.
3. Roger Hardiman <roger@cs.strath.ac.uk> submitted various fixes to smooth
out the microcode and made all modes consistent.
4. Added supported for yuv12 so we know can capture raw streams and feed it
to mpeg_encoder . The upshot is that we can now mpeg encode more and save
nearly 100 percent of the disk requirements previously for programs such
as fxtv first save the raw video image to disk then converted to a
format suitable for mpeg_encode.
This driver includes the following patches submitted by:
1.0 Hideyuki Suzuki <hideyuki@sat.t.u-tokyo.ac.jp>
Japanese Cable support
2.0 Keith Sklower <sklower@CS.Berkeley.EDU>
Minor update to the BSDI section so it compiles cleanly on BSDI
3.0 Joao Carlos Mendes Luis <jonny@coppe.ufrj.br>
ioctl interface to select video format , NTSC, PAL, etc...
Added [SR]RGBMASKs ioctl for byte swapping.
1.16 4/20/97 Randall Hopper <rhh@ct.picker.com>
Generalized RGBMASK ioctls for general pixel
format setting [SG]ACTPIXFMT, and added query API
to return driver-supported pix fmts GSUPPIXFMT.
1.17 4/21/97 hasty@rah.star-gate.com
Clipping support added.
1.18 4/23/97 Clean up after failed CAP_SINGLEs where bt
interrupt isn't delivered, and fixed fixing
CAP_SINGLEs that for ODD_ONLY fields.
