In 2008 I discussed as part of the V4L-DVB microconf extending V4L2 to
support complex media devices. But most of the work until today has been
an effort to lay the foundation of that in the form of an improved V4L2
framework. Hopefully by the time of the conference we have managed to
port all V4L2 drivers over to that framework and we can by then start to
build on it.
This topic would involve explaining the new framework, the problems
encountered while converting drivers to it, and future ideas on how to
improve the framework in order to simplify the V4L2 drivers. In addition,
there is a lot of work being done on merging the Texas Instruments omap
drivers, and hopefully in the near future the davinci drivers, also from
TI. It would be an interesting sub-topic in its own right.
As a result of last year's plumbers conference a new API was designed for
DVB tuners. It would be good to see the end result of that as well.
The complexity of implementing support for hybrid tuners (analog and
digital) is another topic I would like to see.
