Hi All,
I would like to know what APIs are available for Video decoding
acceleration on MeeGo Tablets?
Can we access VAAPI? Can we access OpenMax IL?
What is the kernel that will be on the future MeeGo tablets?
This will depend on what hardware platform you are talking about. For
Intel devices we have people creating Moorestown, Oaketrail, and
Pinetrail based devices with Moorestown and Oaktrail having the same
hardware decode capabilities but Pinetrail having a very different
solution (or no solution, depending on the OEM.)
Moorestown/Oaketrail is enabled via vaapi (with gstreamer elements
wrapping vaapi.) Most app developers will have no need to do anything
other then use the Qt/Mobility API. If the app needs to build an exotic
pipeline then they can directly work with gstreamer, and if the app
already has it's own concept of a pipeline infrastructure then the app
could choose to directly talk to VAAPI.
Some pinetrail based tablets (like the WeTab/ExoPC) have a third party
hd video decoder. There is no such support for this in meego. I have
no idea if somebody is planning to add support, but some kind of linux
solution exist since this is integrated into the Linux that comes on WeTab.
