* media: fix pdf build with Spinx 1.6Mauro Carvalho Chehab2017-08-261-0/+2
| | | | | | | | | | | | | | | | | | | | | | Sphinx 1.6 generates some LaTeX code before each table, starting its own environment before calling tabulary, apparently to improve table layout. The problem is that such environment is incompatible with adjustbox. While, in thesis, it should be possible to override it or to redefine tabulary, I was unable to produce such patch. Also, that would likely break on some future Sphinx version. So, instead, let's just change the font size on bigger tables, in order for them to fit into the page size. That is not as good as adjustbox, and require some manual work, but it should be less sensitive to Sphinx changes. While here, adjust a few other tables whose text is exceeding the cell boundaries.

* [media] v4l: Add metadata buffer type and formatLaurent Pinchart2017-04-141-0/+58
The metadata buffer type is used to transfer metadata between userspace and kernelspace through a V4L2 buffers queue. It comes with a new metadata capture capability and format description.
