00:02 <memeka> ndufresne: even the old xu4 can do 4x1080p@30

00:02 <memeka> (H264)

00:03 <memeka> S905 should do the same h264 and @60 h265 I think

00:48 <memeka> ndufresne: ping

00:52 <memeka> ndufresne: gstreamer is stuck at Pipeline is PREROLLING ...

00:52 <memeka> with H264

00:53 <memeka> dmesg shows:

00:53 <memeka> https://www.irccloud.com/pastebin/e7q659rD/

01:03 <memeka> ndufresne: i increased CMA, no more alloc issues, but still stuck in poll with "nothing to dequeue" :(

01:20 <ndufresne> memeka, it's possible that driver have moved to event only loading, GStreamer needs porting

01:21 <memeka> i c :-S

01:21 <ndufresne> I notice this one in my amlogic build, https://paste.fedoraproject.org/paste/3EmytcHxbqB37hCCdFcXFg

01:22 <ndufresne> not sure if I have upstreamed it yet

01:22 <ndufresne> but mjourdan was to drop CREATE_BUFS support anyway

01:24 <ndufresne> memeka, I will try and make some tests before 1.16 to hopefully get the best I can out of latest venus, coda, amlogic

01:24 <ndufresne> memeka, meanwhile be aware that mjourdan mostly test with ffmpeg

01:26 <memeka> yeah :|

01:28 <memeka> ndufresne: do you still have that trick handy to do primary plane invisible? :D

01:43 <ndufresne> I have modetest -P 32@34:1x1 in my shell history, is that enough ?

01:45 <ndufresne> seems to be enough on the kernel I got

01:49 <memeka> ndufresne: doesn't work for me :( i get nothing on screen if i use overlay plane, video on screen if i use primary plane (with convert)

01:53 <ndufresne> do you get color bars if you do modetest -s 31@34:1920x1080

01:53 <ndufresne> (crtc and planes id may have shifted a little in recent kernels)

01:54 <memeka> ndufresne: yeah crtc and plane id shifted :)

01:54 <memeka> failed to find mode "1920x1080" for connector 31

01:54 <memeka> failed to create dumb buffer: Invalid argument

01:54 <memeka> plane 31 is overlay

01:55 <memeka> works with connector

01:55 <memeka> 29@32

02:03 <ndufresne> great, going to bed early, see you soon

02:03 <memeka> ndufresne: the command worked, still got black screen :P

02:03 <memeka> gnite tho` :)

09:25 <mjourdan> memeka: There's no support for multi-instance decoding at the moment. Requires a different firmware and driver piece

09:25 <mjourdan> I went for the single instance H264 driver as it is much, much less complex than its multi-instance part

09:33 <memeka> mjourdan: I know

10:47 <memeka> mjourdan: any idea why gstreamer is not working?

10:48 <mjourdan> memeka: I haven't tested gstreamer in a while. Every version behaves differently and with the V4L2 M2M spec still in writing it's not easy. I mainly test with ffmpeg and chromium (who both don't fully respect the WIP spec either).

10:49 <memeka> mjourdan: gstreamer h264 was not working, mpeg4 was working but kmssink on overlayplane was not working either

10:50 <memeka> on primary plane it was working, but obv slow because of software conversion to rgb

10:52 <memeka> so yeah had issues with both dec and overlay plane :(

10:52 <memeka> ffmpeg did work to decode indeed

10:52 <memeka> tested with caca output :)
