These are not the features, that we _have_ to implement, these are just the ones, that are related to the snapshot mode: * flash strobe (provided, we do not want to control its timing from generic controls, and leave that to "reasonable defaults" or to private controls) * trigger pin / command * external exposure * exposure mode (ERS, GRR,...) * use "trigger" or "shutter" for readout * number of frames to capture Thanks Guennadi --- Guennadi Liakhovetski, Ph.D. Freelance Open-Source Software Developer http://www.open-technology.de/ -- 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
