Ah... forgot to mention about that. I haven't included the fix for standard setting, because either the stk1160 chip or the userspace application didn't seem to behave properly: I got wrongly coloured frames when trying to change the standard while streaming. Can't your problem get fixed by setting an initial standard (e.g. at /etc/motion configuration file)? > Motion seems to work now, with zoneminder I get a lot of these messages: > Jul 17 23:28:27 localhost kernel: [20641.931990] stk1160_copy_video: 5563 > callbacks suppressed > Jul 17 23:28:27 localhost kernel: [20641.931998] stk1160: buffer overflow > detected > Jul 17 23:28:27 localhost kernel: [20641.932000] stk1160: buffer overflow > detected > > Anything to worry about? > Not sure. If you're changing the standard while streaming then maybe some component is not doing things right. I can take a look at the std thing later, but for now the input fix looks definitely correct. -- Ezequiel García, Free Electrons Embedded Linux, Kernel and Android Engineering http://free-electrons.com -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
