OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) Part 2
Hello, first post here.

I am very excited to have my raspberry pi2 up and running with the latest Milhouse build. I am however having some issues with 3D.

All of my 3d iso files are stored on external hard drives on my PC and I am using windows SMB share to connect.

The movies will all play fine in 2D but unfortunately the vast majority will not work in 3D. When I am presented the option after it loads the ISO I choose "play with 3D mode". Most times it attempts to start the movie and then Kodi stops and reboots itself. Some instances, the movie will play for a minute or two and then reboots in the same fashion.

I have configured it as was instructed in the first post.

Am I missing something? or perhaps someone may have other suggestions.

Thanks in advance.
My latest builds are now based on Kodi 16, you should try a test build from here or if you prefer to continue using Kodi 15 then download the latest official OpenELEC 5.95.5 beta.

Thanks for the suggestion Milhouse. I upgraded to your latest test build but unfortunately I'm still experiencing the same problem. Do I need to purchase the codecs to get it to function?


Thanks
I wouldn't have thought so - post a link to your debug log (wiki) from build #0924 while playing one of your movies, in the Kodi 16 test thread.

Hi Milhouse, is there a latest 15.2 nightly?

I seem to get buffering issues on the 5.95.5 beta build.

No, I'm no longer building 15.x. If you want continued nightlies you'll need to switch to Kodi 16.

Gotcha

Observations:
  1. The MMC driver with default clock won't achieve a 50MHz clock due to even divisor requirement (250/50 => 5, which isn't supported by the mmc driver). Nearest clock frequency with an even divisor (6) is 41.667MHz. However, at 500MHz core_freq, an even divisor of 10 would give 50MHz...
  2. The MMC driver won't accept an 84MHz overclock with core_freq=500 - this should be a divisor of 6 (even) (see explanation)
  3. The performance of the SDHost driver is comparable with the MMC driver at lower overclocks, however the former supports both odd/even divisors whereas the latter is limited to even divisors
  4. The performance of the SDHost driver suffers significantly at higher core_freq with force_turbo disabled. Probably best not to use sdhost at higher core_freq unless force_turbo is enabled. Turbo can be enabled in config.txt, or with:
    Code:
    echo 1 > /sys/devices/system/cpu/cpufreq/ondemand/io_is_busy
    (Edit: Fixed in build #0616 with the introduction of PR:4200)
Possible mmc/sdhost overclocks, based on various core frequencies - adjust core frequency to enable a specific overclock_50 frequency (bracketed items may be too high/unstable):
Code:
Core     mmc            sdhost
Freq     overclock_50   overclock_50

250      63             63,84
275      63             55,69,92
300      63             60,75,100
325      63             55,65,82,(109)

@Milhouse
Hi dear! I see your post about mmc and sdhost overclock, with your test and benchmark.
I'm little confused... I don't undestand if I can use both mmc and sdhost overclock at the same time of if I have to use only one of it.

A configuration like this could be OK?

Code:
arm_freq=980
  core_freq=400
  sdram_freq=400
  over_voltage=2
  dtoverlay=mmc,overclock_50=63
  dtoverlay=sdhost,overclock_50=80

or I have to use only one from
Code:
arm_freq=980
  core_freq=400
  sdram_freq=400
  over_voltage=2
  dtoverlay=mmc
  dtoverlay=sdhost
  dtoverlay=sdhost,overclock_50=80

or
Code:
arm_freq=980
  core_freq=400
  sdram_freq=400
  over_voltage=2
  dtoverlay=mmc
  dtoverlay=sdhost
  dtoverlay=mmc,overclock_50=63
??
thx a lot
@lollo78: Use only one.

I searched the thread for HDMI Passthrough but none of the issues seem the same as mine

When I run the Public 6.0.0 on the RPI2 using my Yamaha amp. The amp says DTS or Dolby Digital with passthrough enabled.

When I run the Chris Swan devel builds I run Jarvis and the amp behaves the same.

On the millhouse builds even with Passthrough enabled the amp says PCM.

Am I doing something wrong with my setup?

Thanks for the help in advance
There's no further support for these old test builds which pre-date current official releases. Switch to the Kodi 16 test builds and post there if you still have a problem.
