Original commit message from CVS: Fix device probing from multiple childs. It's done once in the parent class only now, but the childs do get the correct values. Also fixes an incorrect succesful state change if we opened a v4l device that doesn't have the capabilities that are needed by the plugin. |

General Idea: ============= _____/ gstv4lsrc.[ch] _____/ \ v4lsrc_calls.[ch] / gstv4lelement.[ch] _/____________/ gstv4lmjpegsrc.[ch] v4l_calls.[ch] \ \ v4lmjpegsrc_calls.[ch] \_____ \_____/ gstv4lmjpegsink.[ch] \ v4lmjpegsink_calls.[ch] I.e., all the files on the right are child classes of the v4lelement 'parent' on the left. * v4lelement handles generic v4l stuff (picture settings, audio, norm/input setting, open()/close()) * v4lsrc, v4lmjpegsrc handle the capture specific functions. Maybe we'd need a v4lmpegsrc too * v4lmjpegsink handles mjpeg hardware playback of video Useful Documentation: ===================== MJPEG/V4L API : ./videodev_mjpeg.h V4L API : /usr/include/linux/videodev.h or http://roadrunner.swansea.uk.linux.org/v4l.shtml V4L2 API : http://www.thedirks.org/v4l2/ BSD/Meteor API: /usr/include/machine/ioctl_meteor.h mjpegtools : http://www.sourceforge.net/projects/mjpeg
