Basically, fxtv after 165 capturing in yuv12 mode , switching to rgb 166 would cause the video capture to be too bright. 1671.32 disable inverse gamma function for rgb and yuv 168 capture. fixed meteor brightness ioctl it now 169 converts the brightness value from unsigned to 170 signed. 1711.33 added sysctl: hw.bt848.tuner, hw.bt848.reverse_mute, 172 hw.bt848.card 173 card takes a value from 0 to bt848_max_card 174 tuner takes a value from 0 to bt848_max_tuner 175 reverse_mute : 0 no effect, 1 reverse tuner 176 mute function some tuners are wired reversed :( 1771.34 reverse mute function for ims turbo card 178 1791.35 Roger Hardiman <roger@cs.strath.ac.uk> 180 options BROOKTREE_SYSTEM_DEFAULT=BROOKTREE_PAL 181 in the kernel config file makes the driver's 182 video_open() function select PAL rather than NTSC. 183 This fixed all the hangs on my Dual Crystal card 184 when using a PAL video signal. As a result, you 185 can lose the tsleep (of 2 seconds - now 0.25!!) 186 which I previously added. (Unless someone else 187 wanted the 0.25 second tsleep). 188 1891.36 added bt848.format sysctl variable. 190 1 denotes NTSC , 0 denotes PAL 191 1921.37 added support for Bt878 and improved Hauppauge's 193 bt848 tuner recognition 1941.38 Further improvements on Hauppauge's rely on 195 eeprom[9] to determine the tuner type 8) 196 197 AVerMedia card type added <sos@freebsd.org> 198 1991.39 08/05/98 Roger Hardiman <roger@cs.strath.ac.uk> 200 Updated Hauppauge detection code for Tuner ID 0x0a 201 for newer NTSC WinCastTV 404 with Bt878 chipset. 202 Tidied up PAL default in video_open() 203 204 Soren bumped version from 1.39 to 1.49 to sync 205 with FreeBSD CVS numbers. 206 2071.49 10 August 1998 Roger Hardiman <roger@cs.strath.ac.uk> 208 Added Capture Area ioctl - BT848[SG]CAPAREA. 209 Normally the full 640x480 (768x576 PAL) image 210 is grabbed. This ioctl allows a smaller area 211 from anywhere within the video image to be 212 grabbed, eg a 400x300 image from (50,10). 213 See restrictions in BT848SCAPAREA. 214 2151.50 31 August 1998 Roger Hardiman <roger@cs.strath.ac.uk> 216 Renamed BT848[SG]CAPAREA to BT848_[SG]CAPAREA. 217 Added PR kern/7177 for SECAM Video Highway Xtreme 218 with single crystal PLL configuration 219 submitted by Vsevolod Lobko <seva@alex-ua.com>. 220 In kernel configuration file add 221 options OVERRIDE_CARD=2 222 options OVERRIDE_TUNER=11 223 options BKTR_USE_PLL 224 2251.51 31 August 1998 Roger Hardiman <roger@cs.strath.ac.uk> 226 Fixed bug in Miro Tuner detection. Missing Goto. 227 Removed Hauppauge EEPROM 0x10 detection as I think 228 0x10 should be a PAL tuner, not NTSC. 229 Reinstated some Tuner Guesswork code from 1.27 230 2311.52 3 Sep 1998 Roger Hardiman <roger@cs.strath.ac.uk> 232 Submitted patch by Vsevolod Lobko <seva@alex-ua.com> 233 to correct SECAM B-Delay and add XUSSR channel set. 234 2351.53 9 Sep 1998 Roger Hardiman <roger@cs.strath.ac.uk> 236 Changed METEORSINPUT for Hauppauge cards with bt878. 237 Submitted by Fred Templin <templin@erg.sri.com> 238 Also fixed video_open defines and 878 support. 239 2401.54 18 Sep 1998 Roger Hardiman <roger@cs.strath.ac.uk> 241 Changed tuner code to autodetect tuner i2c address. 242 Addresses were incorrectly hardcoded. 243 2441.55 21 Sep 1998 Roger Hardiman <roger@cs.strath.ac.uk> 245 Hauppauge Tech Support confirmed all Hauppauge 878 246 PAL/SECAM boards will use PLL mode. 247 Added to card probe.

From Randal Hopper<aa8vb@ipass.net> 286 Add option to block the reset of the MSP34xx audio chip by 287 adding options BKTR_NO_MSP_RESET to the kernel config file. 288 This is usefull if you run another operating system 289 first to initialise the audio chip, then do a soft reboot. 290 Added for Yuri Gindin <yuri@xpert.com> 291 2921.62 29 Apr 1999 Added new cards: NEC PK-UG-X017 and I/O DATA GV-BCTV2/PCI 293 Added new tuner: ALPS_TSBH1 (plus FM Radio for ALPS_TSCH5) 294 Added support for BCTV audio mux. 295 All submitted by Hiroki Mori <mori@infocity.co.jp> 296 2971.63 29 Apr 1999 Roger Hardiman <roger@freebsd.org> 298 Added initial code for VBI capture based on work by 299 Hiroki Mori <mori@infocity.co.jp> and reworked by myself. 300 This allows software decoding of teletext, intercast and 301 subtitles via /dev/vbi. 302 3031.64 7 May 1999 Roger Hardiman <roger@freebsd.org> 304 Support LifeView FlyVideo 98 cards. Use EEPROM for card 305 autodetection. Use bttv's audio mux values. 306 Thanks to Paul Reece <paul@fastlane.net.au>, 307 Ivan Brawley <brawley@internode.com.au> and 308 Gilad Rom <rom_glsa@ein-hashofet.co.il> 309 Automatically locate the EEPROM i2c address and read the 310 subsystem_vendor_id from EEPROM and not the PCI registers. 311 Add NSMBUS checks around smbus/iicbus i2c bus code 312 making it easier to compile the driver under 2.2.x. 313 Add GPIO mask for the audio mux to each card type. 314 Add CARD_ZOLTRIX and CARD_KISS from mailing list searches. 315 3161.65 18 May 1999 Roger Hardiman <roger@freebsd.org> 317 Change Intel GPIO mask to stop turning the Intel Camera off 318 Fixed tuner selection on Hauppauge card with tuner 0x0a 319 Replaced none tuner with no tuner for Theo de Raadt. 320 Ivan Brawley <brawley@internode.com.au> added 321 the Australian channel frequencies. 322 3231.66 19 May 1999 Ivan Brawley <brawley@internode.com.au> added better 324 Australian channel frequencies. 325 3261.67 23 May 1999 Roger Hardiman <roger@freebsd.org> 327 Added rgb_vbi_prog() to capture VBI data and video at the 328 same time. To capture VBI data, /dev/vbi must be opened 329 before starting video capture. 330 3311.68 25 May 1999 Roger Hardiman <roger@freebsd.org> 332 Due to differences in PCI bus implementations from various 333 motherboard chipset manufactuers, the Bt878/Bt879 has 3 334 PCI bus compatibility modes. These are 335 NORMAL PCI 2.1 for proper PCI 2.1 compatible chipsets. 336 INTEL 430 FX for the Intel 430 FX chipset. 337 SIS VIA CHIPSET for certain SiS and VIA chipsets. 338 Older Intel and non-Intel chipsets may also benefit from 339 either 430_FX or SIS/VIA mode. 340 341 NORMAL PCI mode is enabled by default. 342 For INTEL 430 FX mode, add this to your kenel config: 343 options "BKTR_430_FX_MODE" 344 For SiS / VIA mode, add this to your kernel config: 345 options "BKTR_SIS_VIA_MODE" 346 347 Using quotes in these options is not needed in FreeBSD 4.x. 348 349 Note. Newer VIA chipsets should be fully PCI 2.1 compatible 350 and should work fine in the Default mode. 351 352 Also rename 849 to 849A, the correct name for the chip. 353 3541.69 12 June 1999 Roger Hardiman <roger@freebsd.org> 355 Updates for FreeBSD 4.x device driver interface. 356 BSDI code removed. Will be restored later. 357 3581.70 12 July 1999 Roger Hardiman <roger@freebsd.org> 359 Reorganise OS device dependant parts (based on a port to 360 linux by Brad Parker). 361 Make the driver compile on FreeBSD 2.2.x systems again. 362 Change number of VBI lines from 16 to 12 for NTSC formats. 363 Changes to probeCard() for better eeprom identification. 364 Added STB Bt878 card identification. 365 Add Hauppauge model identification to probeCard(). 366 Added TDA9850 initialisation code taken from Linux bttv. 367 Juha.Nurmela@quicknet.inet.fi found/fixed bug in VBI_SLEEP. 368 Matt Brown <matt@dqc.org> added MSP3430G DBX initialisation. 369 3701.71 30 Aug 1999 Roger Hardiman <roger@freebsd.org> 371 Small cleanup of OS dependant code.
