Thanks to all for the great help so far, but I've got another issue with upstream driver. In upstream there's no more module parameter for video standard (NTSC/PAL). But there's VIDIOC_S_STD handling procedure. But it turns out not to work correctly: the frame is offset, so that in the bottom there's black horizontal bar. The S_STD ioctl call actually makes difference, because without that the frame "slides" vertically all the time. But after the call the picture is not correct. Such change didn't help: https://github.com/krieger-od/linux/commit/55b796c010b622430cb85f5b8d7d14fef6f04fb4 So, temporarily, I've hardcoded this for exact customer who uses PAL: https://github.com/krieger-od/linux/commit/2c26302dfa6d7aa74cf17a89793daecbb89ae93a rmmod/modprobe cycle works fine and doesn't make any difference from reboot, but still it works correctly only with PAL hardcoded for the first-time initialization. Any ideas why wouldn't it work to change the mode after the driver load? Would it be allowed to add back that kernel module parameter (the one passed at module load time)? -- Bluecherry developer. -- 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
