Hi,
Could you provide us Jason's detailed analysis about V4L2 API gap/issues ?
Do you already have in mind a list of requirements for this API (frame based, asynchronous, memory management/allocation, power ...) ?

Hi All,
Not really sure how this is being discussed in the Multimedia WG. But do we yet have a standardized kernel driver framework for video acceleration?
A bit investigation showed a chaos in this area:
Different SoC vendors are using their specific APIs
The freescale case, there is a proposed driver from Sascha using V4L2
interface, yet our analysis showed some issues with this API to support a full featured usage, and the API itself doesn't just seem to be right for this (thanks for Jason for a detailed analysis)
XvMC (obsolete I believe)
nVidia's VDPAU, which is supported by XBMC and many others though
VA API (Intel proposed and currently available on Intel graphics), can
use VDPAU as a backend
- XvBA - AMD is proposing this for the ATI video HW
