[12:17] <ezequielg> hverkuil: https://patchwork.linuxtv.org/project/linux-media/list/?series=7059 is ready to be reviewed by you.
[12:17] <ezequielg> ah, just noticed you superseeded the others... :)
[12:24] <hverkuil> ezequielg: any other patches that I can queue up as far as you are concerned? I've been on vacation the past three weeks (and little time in the week before that), so I'm still catching up.
[12:30] <ezequielg> we have some other hantro stuff, but iirc they are all in-flight.
[12:47] <wens> the Hantro JPEG related patches could use a look :)
[12:47] <ezequielg> wens: those are quite fine.
[12:47] <ezequielg> wens: I think the only problem is that we don't know exactly why those IO barriers were needed on rk3288.
[12:47] <ezequielg> I copy-pasted that code from very old chromium kernels.
[12:48] <ezequielg> it's entirely possible the IO barriers were needed due to some ancient rk3288 version of the SoC.
[12:48] <hverkuil> ezequielg: if it is OK, then can you add your Acked/Reviewed-by?
[12:48] <ezequielg> and that today are no longer needed.... but .. I don't think we can test that easily.
[12:51] <ezequielg> hverkuil: I am still unsure about a few things, but it's definitely on my radar, given it fixes an ugly hack we had there (the bounce buffer).

[15:26] <hverkuil> jmondi: is Eugen's atmel v3 series for the microchip csi2dc ready to go? Do you want to Ack it or can I make a PR as-is?
[15:36] <jmondi> hverkuil: the csi2dc only ?
[15:37] <jmondi> I've reviewed the previous versions, let me send a tag if it's not too late
[15:37] <hverkuil> no, the whole series (v3 /23)
[15:37] <hverkuil> (sorry for the confusion)
[15:37] <jmondi> hverkuil: ok, I've mostly reviewed the csi2dc, so I'll tag that one at least
[15:38] <hverkuil> Ah, that wasn't clear to me.
[15:38] <hverkuil> So patches 1-3 should be OK as far as you are concerned.
[15:39] <hverkuil> 4-6 look fine as well to me.
[15:40] <jmondi> yes it seems they are too
[15:40] <jmondi> 7/23 isn't clear to me, but if sounds ok to you please take it
[15:41] <jmondi> I'll send a tag for 3/23 a my previous comments have all been addressed
[15:41] <hverkuil> 7 looks weird, I need to dig deeper.
[15:41] <hverkuil> 8 & 9 you already reviewed, I see.
[15:42] <hverkuil> 11 too
[15:43] <jmondi> 10/23 Eugen explained me what's going on, but I still have issues understanding the last part of the patch
[15:44] <jmondi> but that's his driver code, so if doesn't look off to you please go ahead

[16:05] <jmondi> hverkuil: 12/23 is a bit more problematic if I got it right

[16:38] *** camus1 has quit IRC (Ping timeout: 480 seconds)
[16:47] <jernej> rellla: in theory it should be possible, but I never tried it. Note that VP8 is a bit problematic in regards of concurrent decoding multiple streams.
[16:51] <rellla> jernej: i just need mpeg2 and h264. and i need 2 drm planes for that, right?
[16:52] <jernej> unfortunately, only Allwinner SoC with two YUV planes is V3 and siblings
[16:55] *** BrianG61UK has joined #linux-media
[16:56] *** BrianG61UK_ has joined #linux-media
[16:56] <jernej> oh, wait, H616 would be capable that too
[16:56] <rellla> hm, i guess i need to get a H616 then :p
[16:57] <jernej> but there is much work to be done
[16:57] <jernej> or better, use GPU for rendering of one (smaller?) video
[17:00] <rellla> hm. i have video on yuv plane and gui on argb plane. gui is already rendered with gpu.
[17:00] <rellla> like kodi i guess
[17:00] *** GBenji has left 
[17:01] <jernej> sure, but gpu can draw many things on same plane
[17:01] <rellla> so i need another texture to render the video in and compose that onto the argb plane?
[17:01] <jernej> yes, that would work
[17:02] <rellla> ok. it just has to be done ;)
[17:04] <jernej> not sure which SoC do you have in mind and what is size of videos in question, but it might be too demanding for GPU
[17:08] <rellla> H3 or H6. Probably i should work with H6 then. The video is probably at max 480*270
[17:09] <rellla> the more i think about it ... seems the userpace side is not so trivial :)

[17:44] *** gouchi has joined #linux-media
[18:31] <ndufresne> rellla: at 480x270, if you get into issue with concurrent decode, you can always decode 1 stream in software
[19:04] <rellla> ndufresne: the source is a tv stream, so 576i, 720p or 1080i and will be downscaled on drm side
[19:10] <rellla> i think i wrongly expressed...
[19:21] <ndufresne> 1080i on CPU ..., ok forget that option then ...
