With respect to the other stuff inside libv4l2util, they are there for a long time, and not much has changed since them. Yet, I'm not a big fan of exporting them, as they may not be useful to other applications. With respect to the new API I've added, there are not much to change at the get_media_devices stuff. It has just 5 methods: one to retrieve info, one to free data, one to display all info (used by v4l2-sysfs-path tool), and two for getting the alsa devices. Of course, new functions can always be added, and the structs might need more fields. I've added a proper documentation for it. I also added a macro with a version number for the library. This will help userspace apps that would use it to check for the version number. That's said, I'm moving the get_media_devices into a new library, to avoid mixing it with other stuff. As I said, I'm OK to postpone the install to happen for the -next version of v4l2-utils, so I've commented for now the install scripts for it. > Once you install it on systems it becomes much harder to change. > > Regards, > > Hans Mauro -- 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
