Hi there! First of all I thank people of this thread, in particular - Jernej, that they doing hard w ...

First issue is known a long time. Workaround is to stop channel playback and then select another one.

I don't have 3D display, so I can't fix it, but should be doable.

You don't actually need 3d display, you only need to play any 3d movie sample and set kodi 3d mode to over under. Then go to osd video menu and enable swap eyes (sorry can't remember exact english label). It should just swap over under movie parts, but it causes green rectangle on video

Ok, didn't know that. There are three special 3D modes which can be set in script.bin:
DISP_TV_MOD_1080P_24HZ_3D_FP = 0x17,
DISP_TV_MOD_720P_50HZ_3D_FP = 0x18,
DISP_TV_MOD_720P_60HZ_3D_FP = 0x19,

Maybe they will help with this... I will probably fix this when I will do a switch to LibreELEC + Kodi 17, which will take a while.

I actually have no idea what are that options mean. 3D modes in kodi are quite simple thing. Screen should be splitted over under or left right. On 2D display you will just get image splitted into 2 parts (one for each eye). All 3d movies are already recorded as over under or side by side. Resolution is typically 1080p for half over under or half sbs. Each movie part should be processed for each eye, swap eyes is intended to swap parts

Remember I suggested we should look for a way to fine tune the system to lower the buffering issues? The answer appears to be, take Free Memory (after purging cache & packages), divided by 3, then multiply the result by 1024, then times 1024 again. This new string value is then entered under "Programs > Maintenance Tools >System Tweaks >TUXEN XML >Edit Settings > Network Settings > Network >> Add the number to "cachebuffersize" (the number you got) >> change "buffermode" to (1) >> "readbufferfactor" to (4.0). And remember to save with "Write XML, on egress from Maintenance Tools. Then reboot to set the new settings. My run-away buffering is gone, and regular buffering is now very low.

(FMx/3)*1024*1024="cachebuffersize" where FMx is free memory

Copy code

Unfortunately, this string value is subject to change, each time free memory size adjusts by addition or removal of apps, packages etc. I just remembered, OpenELEC suspends to memory on "power off or restart", so to properly institute the new string setting, needs to be a "cold boot", removing power to the unit.

Linux 4.7 has been releases & I see Allwinner processors (incluiding the H3) appear to be covered.

Only GPIO, USB, IR, SD cards and maybe few other things are covered. What is missing is audio, gpu, video, HW decoding. Check this link for status: https://linux-sunxi.org/Linux_mainlining_effort#Status_Matrix
