Hello,
Hello,
I'm wondering why cedrus
https://github.com/FlorentRevest/linux-sunxi-cedrus has never
been
merged with linux-sunxi sunxi-next.
Because it is not ready to be merged. It depends on the v4l2
request
API, which was not merged and which is re-worked atm.
Also, sunxi-cedrus itself is not in a finished state and is
not as
feature-complete to be merged. Anyway it might be something for
staging... Has there been a [RFC] on the mailing list at all?
Where can I find a list of TODOs to get it ready to be merged?
Assuming that the request API is in, we'd need to:
- Finish the MPEG4 support
- Work on more useful codecs (H264 comes to my mind)
- Implement the DRM planes support for the custom frame
format
- Implement the DRM planes support for scaling
- Test it on more SoCs
Or something along those lines.
Lot of work to do
Well... If it was fast and easy it would have been done already :)
:))
I see it seems to be dead, no commit in 1 year.
Yes, because the author did this during an internship, which
ended ...
Afaik nobody picked up his work yet.
That's not entirely true. Some work has been done by Thomas (in
CC),
especially on the display engine side, but last time we talked his
work was not really upstreamable.
We will also resume that effort starting next march.
Is it possible a preview on a separate Reporitory to start
working on now?
Expecially to start porting everything done by FlorentRevest to
mainline,
admitted you've not already done.
I'm not sure what you're asking for. Florent's work *was* on
mainline.
and then they took it off because it was unmantained?
You've spoken about Thomas(in CC) not ready,
maybe I could help on that if it's public to accelerate.
If I'm able to of course, this is my primary concern.
Otherwise, in which way can I help improving it to make it accept
to linux-sunxi?
Starting from Florent's work and porting it to sunxi-next to begin?
And after that adding all features you've listed?
Tell me what I can do(I repeat, if I'm able to).
The bottleneck is that the Request API is not mainlined. We
restarted work
on it after a meeting a few weeks back where we all agreed on the
roadmap
so hopefully it will go into mainline Q1 or Q2 next year.
That said, you can use Florent's patch series for further development.
It should be relatively easy to convert it to the final version of the
Request API. Just note that the public API of the final Request API
will
be somewhat different from the old version Florent's patch series is
using.
So I'm going to try soon to :
1) adapt that patchset to sunxi-next
2) add A20 support
3) add A33 support
4) after mainlined APIs, merge
That sounds good. Thomas already has the support for the A20, and as I
was saying, there is someone that is going to work full time on this
in a couple monthes on our side.
I'll set up a git repo on github so that we can collaborate until the
request API is ready.
Any news about git repo?
When do you plan to do it more or less?
Great!
Write me when you've got news.
Thank you very much!
Maxime
