OK, I know, we don't even know yet when the mini-summit will be held but I thought
I'd just start this thread to collect input for the agenda.
I have these topics (and I *know* that I am forgetting a few):
- Discuss ideas/use-cases for a property-based API. An initial discussion
appeared in this thread:
http://permalink.gmane.org/gmane.linux.drivers.video-input-infrastructure/65195
- What is needed to share i2c video transmitters between drm and v4l? Hopefully
we will know more after the upcoming LPC.
- Decide on how v4l2 support libraries should be organized. There is code for
handling raw-to-sliced VBI decoding, ALSA looping, finding associated
video/alsa nodes and for TV frequency tables. We should decide how that should
be organized into libraries and how they should be documented. The first two
aren't libraries at the moment, but I think they should be. The last two are
libraries but they aren't installed. Some work is also being done on an improved
version of the 'associating nodes' library that uses the MC if available.
- Define the interaction between selection API, ENUM_FRAMESIZES and S_FMT. See
this thread for all the nasty details:
http://www.spinics.net/lists/linux-media/msg65137.html
Feel free to add suggestions to this list.
What about a hardware accelerated decoding API/framework? Is there a
proper framework for this at all? I see the broadcom module is still in
staging and may never come out of it, but how are other video decoding
engines handled that don't have cameras or displays.
Reason for asking is that we from linux-sunxi have made some positive
progress in Reverse engineering the video decoder blob of the Allwinner
A10 and this knowledge will need a kernel side driver in some framework.
I looked at the exynos video decoders and googling for linux-media
hardware accelerated decoding doesn't yield much either.
Anyway, just a thought; if you think it's the wrong place for it to be
discussed, that's ok :)

next week, as I am travelling a lot.
