Hello everyone, the following message is in two parts, the first part is a recent problem that I have, and the second part is an attempt to improve the secam mode (I'm sorry for a so long message). a sketch of my configuration is the following: - Hauppauge Wintv (pal) + radio (model 1998) [bttv0] - Hauppauge Wintv Theater (pal/secam) [bttv1] - kernel 2.2.17+Reiserfs+i2c-2.5.1 - bttv-0.7.57+xawtv-3.30 - tv source: cable bttv0 on irq9 (shared with aic7xxx and eth0) bttv1 on irq10 mb/cpu: asus p2b-ds/p2 450 I have included the (full) dmesg of the driver at the end of this mail. The 1st problem is the following: if I use bttv-0.7.5x with x=8,9 and xawtv-3.30 or higher: at first xawtv display the image, but as soon as I want to change the channel, I have a complete freeze of xawtv, the sound is still running, but the capture and xawtv is completely frozen (I need to 'kill -9' it). If I use bttv-0.7.57 with a xawtv-3.36 or higher (I have trouble to compile the other versions between 3.30 and 3.36), then I have the same scenario. But bttv-0.7.57 and xawtv-3.30 is ok. Any clues of what is wrong here ? Notice, that I also have a lot of ioctl: VIDIOCSWIN(win=128x96+0+0,key=0,flags=0x0,clips=1): bad address returned by xawtv, each time I change the channel. The 2nd part of the email is most likely related to secam mode: (1) With bttv-0.7.x (say 40<= x <=57), there is a green frame on the left side of the screen (as an example see http://www.math.univ-montp2.fr/~pev/sample-with-the-green-frame.jpeg). This occurs with a sufficiently large screen, but of course is always present when we grab the display. NB: this problem doesn't occur with the bttv drivers of the 2.4.x kernels, neither with the recent versions of bttv2 that I have tried. (2) Problem with the VCR: when we use Composite1 in SECAM mode the quality is pretty poor (in PAL mode with of course a VHS/PAL the quality is perfect), as two examples see http://www.math.univ-montp2.fr/~pev/sample-with-thesimpsons-SECAM.jpeg (with bttv-0.7.53) http://www.math.univ-montp2.fr/~pev/first-contact-SECAM-sample.jpeg (with bttv2 version 11/01/2001) NB: sometimes, even some frames are lost. (3) Problem with the sound (this one seems specific to me): the Nicam detection of the channels is quite heratic. For instance between the 0.7.40 and the 0.7.57, I had around 5 channels detected in stereo (but in theory most of them are in stereo), unfortunately never with the same driver (well with 0.7.57 I have 3/4 channels in stereo). Furthermore, it could also depend of unknown parameter. For instance sometimes a reload of the same driver (i.e. rmmod and a new insmod), a channel which wasn't detected stereo is now correctly detected (or vice/versa). I have tried to force the stereo mode in the driver (a very bad hack), but without success. On the other hand, I could say that the mono sound is crystal clear. The last, is more technical. Almost all VCR model sold currently in France are able to display NTSC video on a PAL TV (which is the case of all tv here). With bttv/xawtv, if I put a NTSC video, and I select PAL mode (or a PAL variant), then the image is in color but "doubled" (i.e. there is two images, one shifted relatively to the other), but if I select NTSC, then the image is reasonable but black and white. Is there a way to trick it in order to get the best of both worlds ? Thanks a lot for your patience and any advices. If you need more infos, don't hesitate to ask. best regards, Philippe. driver message (option of bttv radio=1, option of msp3400 simple=1 debug=2): bttv: driver version 0.7.57 loaded bttv: using 2 buffers with 2080k (4160k total) for capture bttv: Host bridge needs ETBF enabled. bttv: Bt8xx card found (0). bttv0: Bt878 (rev 2) at 00:0a.0, irq: 9, latency: 32, memory: 0xe2000000 bttv0: subsystem: 0070:13eb => Hauppauge WinTV => card=10 bttv0: model: BT878(Hauppauge new (bt878)) [autodetected] bttv0: enabling 430FX/VP3 compatibilty PCI: Enabling bus mastering for device 00:50 bttv0: Hauppauge msp34xx: reset line init i2c-dev.o: Registered 'bt848 #0' as minor 0 tuner: chip found @ 0x61 bttv0: i2c attach [(unset)] i2c-core.o: client [(unset)] registered to adapter [bt848 #0](pos. 0). msp34xx: init: chip=MSP3410D-B4, has NICAM support msp3410: daemon started msp3410: thread: sleep bttv0: i2c attach [MSP3410D-B4] i2c-core.o: client [MSP3410D-B4] registered to adapter [bt848 #0](pos. 1). i2c-core.o: adapter bt848 #0 registered as adapter 0. bttv0: Hauppauge eeprom: model=61334, tuner=Philips FM1216 (5), radio=yes bttv0: i2c: checking for MSP34xx @ 0x80... found bttv0: i2c: checking for TDA9875 @ 0xb0... not found bttv0: i2c: checking for TDA7432 @ 0x8a... not found msp34xx: AUDC_SET_INPUT(4) bttv: Bt8xx card found (1). bttv1: Bt878 (rev 2) at 00:0b.0, irq: 10, latency: 32, memory: 0xe1000000 bttv1: subsystem: 0070:13eb => Hauppauge WinTV => card=10 bttv1: model: BT878(Hauppauge new (bt878)) [autodetected] bttv1: enabling 430FX/VP3 compatibilty PCI: Enabling bus mastering for device 00:58 bttv1: Hauppauge msp34xx: reset line init i2c-dev.o: Registered 'bt848 #1' as minor 1 tuner: chip found @ 0x61 bttv1: i2c attach [(unset)] i2c-core.o: client [(unset)] registered to adapter [bt848 #1](pos. 0). msp34xx: init: chip=MSP3410D-B4, has NICAM support msp3410: thread: wakeup msp3410: daemon started msp3410: thread: sleep bttv1: i2c attach [MSP3410D-B4] i2c-core.o: client [MSP3410D-B4] registered to adapter [bt848 #1](pos. 1). i2c-core.o: adapter bt848 #1 registered as adapter 1. bttv1: Hauppauge eeprom: model=37266, tuner=Philips FI1216MF MK2 (3), radio=no bttv1: i2c: checking for MSP34xx @ 0x80... found bttv1: i2c: checking for TDA9875 @ 0xb0... not found bttv1: i2c: checking for TDA7432 @ 0x8a... not found msp34xx: AUDC_SET_INPUT(4) msp3410: setting mode: autodetect start (0x0001) msp3410: thread: wakeup msp3410: detection still in progress msp3410: detection still in progress msp3410: setting mode: autodetect start (0x0001) msp3410: detection still in progress msp3410: detection still in progress msp3410: detection still in progress msp3410: detection still in progress msp3410: current mode: ERROR (0x0000) msp34xx: setbass: 32768 0x00 msp34xx: settreble: 32768 0x00 msp34xx: setvolume: mute=off 65535:65535 v=0x73 b=0x00 msp3410: thread: sleep msp3410: current mode: 6.5/5.85 L NICAM AM (0x0009) msp3400: NICAM setstereo: 1 msp3400: switching to AM mono msp34xx: scart switch: mono => 0 msp34xx: setbass: 32768 0x00 msp34xx: settreble: 32768 0x00 msp34xx: setvolume: mute=off 65535:65535 v=0x73 b=0x00 msp3410: thread: sleep msp3410: thread: wakeup msp34xx: nicam sync=1, mode=8 msp34xx: watch: stereo 1 => 2 msp3400: NICAM setstereo: 2 msp3410: thread: sleep
