Yocto image issues

[stephan]

Hi,

Please post here the issues related to this image
For any feedback, do not forget to precise your target.
When issues are related to specific video streams, the best way to report is to send an extract of the faulty video so that I can reproduce and investigate.

Hi,

First of all, thanks for the great job you´ve done there.
I have briefly checked the WB quad image, and found that external subtitles arent working. I mean, XBMC dosen´t recognize *.srt included in the same folder.
About videos not been played, just a couple, one of them was the 15 Mg
TEST TOOL Ac3 Dolby Digital 5.1ChSoundTest.

Regards!

I’ve now a bit of testing.
1 SD ubuntu uptime about 20 minutes 44-46°C
2 SSD yocto 0.0.4:

15:07:01 up 22 min, 1 user, load average: 12:49, 00:57, 00:46
root @ utilite: ~ # cat / sys/class/thermal/thermal_zone0/temp
65

Yesterday I had found that the utilité is quite warm in my opinion.

Hi,

I am using your newest image on an udoo-quad. After a full restart of the board, the playback in xbmc is working fine but when the xbmc is running for a longer time, I only get audio playback.

dmesg:

[79742.156748] mxc_v4l2_output mxc_v4l2_output.0: Bypass IC.

xbmc.log:

A restart of xbmc.bin does not solve the problem. I have to reboot the hole system.

The problem exists with all files that I have testet (mainly 1024p/720p h264)

Regards!

P.S.: I am using a self compiled kernel to have NFS3/4 and BtrFS, so I am not 100% sure that this problem exists in the official version but I have not changed any source.

Hi Joseba,

I have just given a try a external subtitles and they work fine for me (external srt file with same file name as movie).
It is known not to work with UPNP (because xbmc cannot see them, check here) but they work fine with local content, or SMB/NFS shares
For TEST TOOL Ac3 Dolby Digital 5.1ChSoundTest, you are right : It is a divX3 codec which is not played (divx4 and divx5 are correctly played but not divX3) : I think I know what the issue is and should be able to fix it very quickly…

[stephan]

Hi Ralix,

First no panic : 66°C as a core temp is not dangerous for your device.
Then there is an easy explanation for the difference with ubuntu.
When you launch my image, you automatically launch XBMC and the main page requires permanent GPU activity (especially for displaying the RSS feed) which is largely responsible for the heat dissipation you mention.
If you want to lower temperature you can :
– Stop XBMC (most efficient)
– Disable RSS feed (it will really improve GPU load)
– Move to another page on XBMC GUI

Stephan

Hi mrpi_314,

Unfortunately I know the symptoms you describe.
You are faced with a memory allocation failure.
When it happens can you try the following :
First, issue commands

  free -m
  cat /proc/zoneinfo
  cat /proc/meminfo

And send to me the outputs

Then, issue the command :
echo 3 > /proc/sys/vm/drop_caches

And try again to launch your movie…

Regards
Stephan

Hi Stephan

I have already noted it in your blog section, but I thought I would write it here again so that everyone knows and can maybe share their experiences related to my issues experienced on my Udoo Quad:

1. Aeon MQ5 Skin(Can’t successfully enable the skin). It automatically reverts back to the default Confluence skin when I try enable MQ5 skin. Anyone else experienced this?

2. Sports-a-holic add-on(part of the mash2k3 repository). XBMC tells me I cannot install this add-on due to missing dependencies. Any idea what it needs to be able to work? Anyone else experienced this?

3. My 1080p movies playback with stutter(flickering of the screen) and eventually cause my Udoo to freeze up completely and reboot is required. Stephan is helping me investigate this already…but has anyone else experienced this with any of their 1080p movies and if so what types of video files were they? To provide you more info about the files I ma having a problem with: One is a 12GB 1080p x264 mkv with DTS. It is the film Prometheus.

Thanks again Stephan for all your hard work and help! and I am interested to hear from the rest of the community if anyone has experienced problems similar to mine and if so compare notes

Hi mrpi_314

Thanks for your feedback
Obviously another DMA allocation issue for VPU…
Unfortunately I have merged this patch from wandboard which should help but it is still not a the silver bullet solution…

Just tried the utilite_yocto_v0.0.4.img.xz on my utilite pro, all that happens is I see a splash screen for wandboard and that’s it. No console output either. Not sure if there is something wrong with the image I downloaded so I’m trying again, just in case I accidentally got the wrong image. Just downloaded and verified the md5:
6b992d86b7fa7164ada3f2b3e7958386

Will do the install and see what happens this time around.

Thanks for your work!

[Gabriel Guzman]

Confirmed, I have the same problem after re-trying the utilite image. I get a wandboard.org splash screen and then nothing else.

[Simon]

Hi Stephan,

thanks a lot for your great work. Im succesfully using your image on my wanboard quad, and it is playing most of my stuff without any jerks. There are just 2 things I recognized:

1. I’m not able to play Ac3 passthrough over Spdif (DTS is working), means I can play the file, but there is no sound. If I turn passtrough off, sound is working perfectly.

2. There is no scaling-method option for SD-Videos, which makes them a little “rough” looking on HD-devices. I guess this is a vpu-driver issue, and therefore you will have probably no influence on this until there is a new driver coming out…

Hope you keep on this really good work!

Simon

[stephan]

hi simon,

Maybe you can try the try pointed by peter : http://stephan-rafin.net/blog/2014/01/29/yet-another-yocto-image/#comment-1787
iecset -c 1 audio 0

Regards

[stephan]

@Gabriel :
Hi sorry for the delay of my fix : Could you try this new version please :
https://stephan-rafin.net/owncloud/public.php?service=files&t=7846b16cb79e2f4e9ca45a78b65d07f5

Best regards
