I uploaded the patches here <https://sites.google.com/site/rawbdagslair/libv4l-mcplugin.7z?attredirects=0&d=1>(16kB). Basically, I used Yordan's patches as a base and worked from there to fix up his source code and Makefile for cross-compiling using OpenEmbedded/Yocto. There are a ton of minor issues with this, starting with the fact that I did not put proper copyright notices in any of these files. Please advise if this poses a problem. Only integral frame size support and no support for native read() calls. There's a dummy read() function, because for some reason this is required in libv4l2 0.9.0-test though it's not mentioned anywhere. As the original plug-in by Yordan, there is currently no cleaning-up of the internal data structures. I used this in conjunction with the Gumstix CASPA FS (MT9V032) camera using some of Laurent's patches and some custom patches which add ENUM_FMT support to the driver. Basically, upon opening a given device, all trees are configured once to load the respective end-point's formats for emulation of setting and getting formats. Then regular format negotiation by the user application takes place.
