I decide to rebuild all from your new sources, but my build stoped on gcc step with strange issue: ...

Strange, I build everything from scratch few days ago and it worked.  Remove all build folders and try again...

fsmoke

at last i tested tvout with latest build i'ev got first results

It's on tv tuner board



And on real tv hardware



As you can see with splash screen all ok - but it's needed to be redrawn(or prograppatically resized)for tv aspect. Unlike splash - main stuff picture aligned to the top of the screen, and on real hw tv it's cropped.

PS
We need to test it with ntsc mode too...

jernej

Can you explain your modifications?

fsmoke

Absolutely nothing unusual

1)I downloaded latest sources from 28.04.2016.
2) fix opipc.fex to tv(2) mode pal(11) and disp_mode(1)
.....
[disp_init]
disp_init_enable = 1
disp_mode = 1
screen0_output_type = 3
screen0_output_mode = 10
screen1_output_type = 2
screen1_output_mode = 11
fb0_format = 0
fb0_width = 0
fb0_height = 0
fb1_format = 0
fb1_width = 0
fb1_height = 0
.....
2)start to build it
3)when kernel sorurces already fetched but still not builded - apply your patch(post no=19) or just uncomment tve_clk_enable in drivers/video/sunxi/disp2/tv/drv_tv.c(as you tell me earlier)
4)wait to the end of build
5)write img to flash
6)profit

May be your device doesn't support pal - try to ntsc(screen1_output_mode = 14)

By the way i think you may already include kernel patch(about tve_clk_enable) to the main source branch. i think nothing will no longer be edited here.

fsmoke

Brilliant!!!! we did it !!



i just swich it to NTSC mode (screen1_output_mode = 14) and finally got fullscreen picture. later i will try to setup aspect inside kodi. And little cropping also exists...

PS
Strange thing - on my computer tv board - i have no signal when ntsc mode is turned on, it seems my tv tuner supports only pal signal. It is again about your TV device - may be you got distorted picture cos your device does not support pal.

What about video playback? Does it work or is there only black screen?

I'm a bit confused, is patch needed or not?

EDIT: Now that I read everything again, I see that patch is needed.

No playback haven't tested yet. Patch needed only for uncommenting tve_clk_enable line.
Changing fb0 to fb1 in kodi NOT NEEDED!


By the way you must check your cable - it must be the same as picture below

I tested playback right now - just black screen . Have you any ideas how it will could be fixed?

jernej

Yes, check post #14. Just ignore those which are about fb0. But until I manage to sort issues with my analog display + cable, I won't be able to actively help.
