v18 -  LibreELEC Testbuilds for RaspberryPi (Kodi 18.0)
(2018-01-20, 02:56)smp1 Wrote: @popcornmix 
I did some more testing with different chunk sizes and I think 64K is the optimal value. 32K works ok but I get occasional buffering at the start of playback of some TS files. With 64K the playback always start immediately. BD ISOs also work fine.
I did some intensive testing tonight:

- 32k chunks (thanks @smp1 for your build) plays almost well in a structurized 100 mbit environment. With typical 3D HBR ISOs very litle glitching during 2 hours & fast initial reading (<10 sec).

But as the usual purpose of SMB are servers w/o a structurized connection, I tested my real setup with ~100 mbit powerLAN and additionally with Wifi (~80 mbit/s):
- both connections don't work with 32k chunks (stuttering every ~10 secs.). So I changed to #0115 with large chunk size and both environments played absolutely w/o any stuttering Smile

Conclusio: chunk size seems to be the most important parameter for SMB users in terms of flawless playing. I think 64k could be still to small (as 32k didn't work at all with indirect connections).
- Is it possible to make this parameter visible/editable (e. g. in advancedsettings.xml)?
- Otherwise @smp1 could you share your test builds with 64k and 128k so I can further test (it would be great if you have pre #1501-builds for that, because then we have a version running SMB AND 3D flawlessly)

thanks

Reverting both commits restores functional 3D playback. 
Thanks @Milhouse for clarification - do you plan to revert those until the bug is found? Any testing that I can provide?
Hope we get a SMB plus 3D version running - copying movies to usb sticks and put it then into the Pi is so old style ;-)

Hello,
sorry. with build #0119 i am unable to play all my bluray-files over smb.
Much buffering on br-menue or they would'nt start (bd50).

I do not have iso files on my network, only rips.

I'm back to #118, works fine for me.
Thanks

Not at the moment - I'll leave that decision to @popcornmix. Using #0114 might be the best option until there's a fix.

Re: build 0120

Having problems with 3d. iso and mkv files work fine. siff and m2ts files don't. 3d.mvc.mts files switch my tv to 3d but do not play properly.

Thanks

I did some more testing. 1024K and 512K are unusable - BD ISOs open very slowly.
256K is better but still slow with some ISOs (20+ seconds).
128K is better but much slower than 64K.

I get the best results with 64K.

Yes, this was actually a mistake on my part as I had forgotten to disable the revert of the 2 ffmpeg commits in build #0120. 3D ISO will not work in future builds (ie. #0121) unless a fix is committed upstream. Apologies for this unnecessary confusion.

Re Build 121 on Raspberry Pi 3

Just tested 121 for playing 3d files.

iso and mkv files work ok.

siff and m2ts files fail to be recognized as 3D.

3d.mvc.m2ts files are recognized as 3D but do not display correctly

Regards Trevor

64K seems to be the absolutely perfect setting. (RPI3 / Wired connection)

Hi Milhouse & Popcornmix.
I am getting a large memory leak while playing HEVC, it's worse with higher quality/bitrate files.
System Log and Crash log at:-
http://ix.io/Evy
http://ix.io/Evz
Full log extracted from logging directory https://www.dropbox.com/s/bgz6o72to1fb9t...5.zip?dl=0
I did enable debug logging for the most recent crash.
I am using a Pi3, I only tend to use your x builds, so this is with the latest 20180115215804-#0115x.
As an example, I started with memory reporting 592468K by the time I get the crash there is only 51500K being reported, this can be as quick as 5mins.
I could not log in using ssh once everything locks up, had to power off, could not reboot.
Let me know if you would like any other info.
Kevin.

Thanks @smp1 for the test builds!

I tested more and agree with you that 64k chunk size works fine with direct (wired) connection. But from 64k to 128k there is a big improvement in terms of reduced stuttering for non-direct conncetions (the initial setup with 2048k worked flawlessly). 128k still has some glitches but ISO opening time is acceptible (ca. 15 secs). So I would vote for 256K - it prolongs the opening time (to my mind compared to stuttering in a still acceptible level hopefully) but increases the chance, that people can watch hibit media via SMP.

BTW: does the protocol level influence the overhead/net speed (i. e. is a SMP1 connection faster/slower than a SMP3 connection)? If so, I will test the fastest standard as this is selectable directly in KODI settings.

Any chance to make the chunk size selectable or distinguish chunk size for initial reading and media playing?

Cheers
