All, Wondered if someone could advise... I'm from an NTSC and PAL capable tape deck, in the UK. I believe that means the signal coming from the deck will be NTSC_443 compliant. What is captured through VLC or XAWTV is slightly grainy black and white (no green band). It kinda looks like the there are no capture distinctions between NTSC_443 and NTSC. I'd try tweaking the code around this, but I'm not clear where it's controlled from. Can someone help guide me? I have a mountain of these tapes to capture for a museum. Here's the setup: U-matic Sony VO5630 VTR using BNC to RCA video out V4L2 device Pinnacle Dazzle DVC 90/100/101/ using driver: em28xx (version: 0.1.2) Fedora 14 VLC 1.1.12 I know about the issue with changing video standards in this VLC UI version. That's not the problem, and I've confirmed it with a slightly more up to date Ubuntu equivalent. I get the same behaviour in XAWTV and VLC. Here's some of what my experimentation has shown. * On PAL tapes this gear works fine (with the deck switched to PAL and VLC set to PAL) * Direct to TV the gear works fine in NTSC mode (bless modern flat panels) * Using Windows and AmCap I get colour video on the NTSC tapes. __The setting that work there is NTSC_443 with a YUYV colour space.__ * I've tried all the different standards available in VLC and XAWTV with the deck set to NTSC and an NTSC tape. I see no visible difference between NTSC, NTSC_M or NTSC_443 -- and based on work in Windows, I believe I should. * Debug from V4L/VLC shows NTSC_443 is supported in the driver. There's clear evidence I can get some kind of tool chain to work in Windows. But I wondered if there wasn't some fine tuning to the driver that would get Linux rig to work. And I wondered if there were known issues around the NTSC_443 norm. Forgive me if I've missed any, but I haven't found any so far. -- Colin -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
