Video files < 10GB/hour slowly running out of cache

envagyok · October 11, 2016 at 10:17 AM

I tried with MiniMX, Gb LAN, fast NAS. Latest 3.October 2016 dev firmware
With big (30GB/2hour) movies I don't have problem, movie start caching vq70%, slow reduce to 50%, but stay there, and no problem with playing.
Smaller files (for example 9GB/2hour) start the playing at vq70%, but reducing isn't stop at 50%, it continue to vq0%, and sometimes very small jam noticeable.
i try edit advancedsettings, but no luck

Ah! Cache management... Having the same problem since day 1, posted here, also posted @ Alex forum (same problem with both builds). Several people responded "having this problem too", devs included some partial fixes at times (see whats changed in all releases), so, i take it its a well known issue with no fix yet.
What you describe becomes worse with even smaller videos ( tv show episodes ) and imho its a showstopper for 1G devices that are "heavily" used (lots of browse library videos / play start-stop )

Hi,

I see the same with my wetek hub. Will check the 100MBit MXQ later.

Can you guys give the new development build a spin and judge if it's any better? 2016-10-11-devel

Stuck at bear logo for me

If it's stuck there you probably don't have a proper device tree. Do you run from SD card or internal?

I think I know the reason - dtb always updates to "standard" one for 1Gigabit devices. I will fix that today evening.

Meanwhile if you boot from SD card, replace dtb.img manually using your computer.

I have internal install, first I dd new device tree file /dev/dtb
Then copy new image file to update folder, and restart.
I used
gxbb_p200_1G_1Gbit.dtb
Tree file on my mini mx 1/8GB

Interesting.
I wait with stucked bear screen after update 10 min long, the pull out power cord, and pull back, and voila, booted.
This above I don't understand, but now working.

I tested with 3-4 files, seems working good, the VQ always between 90-100%. I tried big, average, and small files too..
Perfect, thanks!
What was the problem?
[hr]
And I noticed also very fast chapter switch, and seeking.
[hr]
I made restart, then stuck again at logo..
I make again power disconnect, and boot again.
Something is wrong with this build.
[hr]
I copy back original dtb from 10-03 build, and restart, stuck bear..
Made power off/on , then boot.
I copy 10-03 build to update folder, restart-stuck-power off/on-boot, update.
With 10-03 build working restart again.

I used to have a MiniMX but it blew down, I can't test on the same device.

On the other hand, this devel build boots just fine on my WeTel Hub.

It boots on MINI MX-G from SD card.

Yes, reboot and reboot to nand works fine.

Just to add my experience...
Stuck this on a Beelink Minimxiii last night.
It installed / ran fine. Tried a reboot, froze at the bear screen.
Pulled the power and again froze at the bear screen. Repeated a few times, same.
Unplugged my external hard drive and it cold-booted fine.
Rebooted without external HDD and no problem.
Tried again a few times with and without external drive connected - rebooted fine.
A bit odd (not seen that freezing previously) but it's not repeatable (so far).

Edit: same behaviour today.

Be aware the advancedsettings.xml options for caching have changed name in Kodi 17: HOW-TO:Modify the video cache - Official Kodi Wiki

If you don't update your advancedsettings.xml when switching to Kodi 17 you wont have any non-default caching options.
