<ayaka> it doesn't, it would harm, I could start up
<LiquidAcid> ayaka, mali is not upstream ;)
<LiquidAcid> why would someone backport something that mostly works with a very specific kernel version (vendor kernel) anyway
<ayaka> I though somebody would like to modification those source to make it work with upstream kernel
<ayaka> and release with the upstream update
<LiquidAcid> i guess that "somebody" exists, but just liking something is usually not enough :)
<ayaka> either it is not public nor well known
<LiquidAcid> or it simply doesn't exist
<ayaka> it could be
<ayaka> basically, I want to solve the output speed of decoder
<LiquidAcid> not sure what that has to do with mali?
<ayaka> someone complaining that the output of decoder is NV12, which making it necessary to convert to RGB before output
<LiquidAcid> which decoder are we talking about?
<ayaka> LiquidAcid, the MFC v5
<javier__> ayaka: I think the problem is more that you are using videoconvert for color space conversion
<LiquidAcid> ayaka, but the MFC has nothing to do with mali
<ayaka> that is right
<ayaka> here comes two solutions
<javier__> in theory the Exynos general scaler (gscaler) should be able to convert he NV12/21 format to the RGB supported by the display controller
<LiquidAcid> ayaka, and v5 afaik can _only_ output nv12
<ayaka> one using the GLES to draw the output which supports nv12
<LiquidAcid> iirc that is a hardware limitation
<javier__> ayaka: so you could either chain the s5p-mfc with exynos-gsc v4l2 m2m or use the exynos-drm gsc support
<ayaka> the other may for the other platform but not exynos, directly render to video controller support nv12
<ayaka> javier__, do you mean the fimc? I don't know which is gsc
<LiquidAcid> ayaka, fimc is only available on exynos4
<LiquidAcid> ayaka, gscaler is the counterpart on exynos5
<ayaka> yes I know, you see I use the MFC v5, so it is exynos4
<javier__> ayaka: right, I thought you were using exynos5, not exynos4
<LiquidAcid> ayaka, while both share an infrastructure in DRM (IPP), IPP is more or less broken, so using it in its current state is not recommended
<javier__> ayaka: forgot the mapping between Exynos SoC and MFC IP block versions :)
<ayaka> I hope the fimc would works fine, last time I test it with gstreamer, I meet a Colorspaces in encoder
<LiquidAcid> ayaka, you can also use the fimc via the v4l2 subsystem, probably ndufresne can tell you more about this
<javier__> ayaka: so *I think* you could use s5p-mfc -> exynos4-is -> exynos-drm
<javier__> but yes, ndufresne has an exynos4 and I know he was using s5p-mfc and the fimc
<ayaka> javier__, btw, does exynos release the jpeg encoder/decoder example code?
<LiquidAcid> and until marek fixes up IPP or creates something else, the only viable option is to use v4l2
<javier__> ayaka: I don't know tbh, probably the state of s5p-jpeg in mainline isn't that great...
<ayaka> I looked back the mail list, a samsung guy said he would released a example in a hour but it never
<javier__> ayaka: do you have a link?
<LiquidAcid> ayaka, have you search the tizen repos=
<LiquidAcid> ?
<LiquidAcid> ayaka, libcamsrcjpegenc-hw-e3250 could be related
<ayaka> LiquidAcid, I see
<javier__> ayaka: probably worth answering to the thread you mentioned and ask for the example. If you give me the email address, I can also ping him internally on Monday and let you know
<ayaka> javier__, I fogot it, finding
<LiquidAcid> javier__, which division are you again?
<javier__> LiquidAcid: it's the Open Source Group
<LiquidAcid> javier__, yes, but iirc then there are multiple locations (like poland e.g.)
<javier__> LiquidAcid: that's correct, I work for Samsung Research America
<LiquidAcid> k
<ayaka> it is really a little hard for me to remember such old thing
<ayaka> currently I am doing work for the other platform, so I can't pay my main time in samsung, but I would to do some contribute in weekend
<ayaka> LiquidAcid, thank you
<ayaka> javier__, thank you

<ndufresne> i'm working on a wip3 branch now
<ndufresne> the drm patches are incorrect, while I believe the FIMC one could be merge
<ndufresne> The colorspace fix is a partial fix, I would need to dig up what are the colorspace actually implement on this HW
<ndufresne> there remain some issues when using certain width height, since the driver round in the middle, instead of rounding up the width/height
