To those guy who cares Rockchip
There is a update about Rockchip media framework, I decided not to
continue of developing the VA-API driver for produces purpose(both
official and private plan). As there is really to much problem with
VA-API with V4L2. But I may develop the VA-API driver to know how to
expend the parser in Gstreamer.
The currently Gstreamer plugins using a rockchip video parser and HAL
layer library could be located here
https://github.com/rockchip-linux/gstreamer-rockchip
For the future develop plan, I would try to move all the thing to
Gstreamer V4L2 plugin, maybe I would create a new plugin. But it would
be a long time to go. As there is no critical need of the Media
framework for Rockchip in Linux, the official plan would be paused, if
the kodi or LibreELEC is not interesting to my supervisor, this plan
will become my private plan, but good news is that my plan about the ISP
support would become official.
Any the result would be there is a standard V4L2 API and a driver for
those stateless video driver(Do remember we don't need firmware). And I
would use the Gstreamer in userspace and welcome the other to offer the
support in the other project.
For the those project who have supported the ffmpeg, I would suggest you
to add support for Gstreamer, the role of Gstreamer in a player is not
different to the ffmpeg. The support of ffmpeg of Rockchip project would
be dropped, as we need a power way to rendering decoding result for
those 4K video. The Gstreamer is the only Media Framework who could
offer a static interface and easy to extend. Even the Gstreamer,
currently I found it could only cover the 80% solution of I would meet,
but it is enough for Linux.

Hello Randy,
I would like LibreELEC to run great on a wide range of devices including
rockchip so it is good to have direct contact - thanks Lionel.
Our core focus is Kodi so I have cc'd Keith Herrington from the Kodi
project board. Keith and senior developers on Kodi’s team can guide you
on their technical direction and requirements for Linux. Once there is
agreement on the right approach for your developers we can start looking
at hardware support.
Kind regards,
Christian

Hi Christian,
I have been looking around recently to RockChip latest SoCs, which are
RK3288 and RK3399.
They seem great on paper, and I have some interest in those.
What i know about those so far is that :
- They Run Linux 4.4
- They Have some V4L2 compliance which was made by rockChip for
Google/chromium
- They also have a va-api wrapper (only supporting h264 so far, but
intended to be extended in a near future to other codecs)
- They have some muscles (A72 for RK3399) and Mali 8XX as GPU which
makes them probably snappier than AML SoCs.
I am considering investigating this as a potential platform for US,
which means integrating it into LE.
I am not sure if that would be a valid approach, or if that would meet
any kodi eventual requirements as well.
I'm available to discuss that with you anytime.
I will cc also Ayaka to this email. He's a Rockchip employee in charge
of Linux Support.
Should you have deeper technical questions about this, he will
probably be able to answer that :)
Cheers,
Lionel
