I can reproduce. Had a chat with @pelwell and the belief is this is harmless. I'll try to log exactly what is occurring and get a fix, but in the mean time it should be safe to ignore it. |

OK @popcornmix thank you ! To be more precise, we run about 200 raspberry pi for a in-store network, and everyday we have to reboot one or two of them because omxplayer is freezed. In the same time the load average increases dramaticaly to 4, 5 or even 10 11 if we do nothing. Somethimes a "reboot" command doesn't work and we have to do I investigate on this issue for 2 years... tried everything that is in my limited debian knowledge: upgrades/downgrades of raspbian/minibian/omxplayer, changing pi cards, power supply, sd card brand, even hdmi cable... So, maybe this the issue here is related to the freeze problems but I don't know. |
|
Can you try getting this libbcm_host.so and replacing the one in /opt/vc/lib |
|
Warning is still here, even after replacing file and reboot
|
|
Yes. Can reproduce (now with raspbian). |
|
I don't notice the same behavior. The failure can occurs while playing a video without changing or stopping it. But the failure never occurs when playing the first video after a reboot. Omxplayer must have stop at least once before there is a problem. |
|
Just a question, is that normal that memory usage rapidly falls down to 10M (and sometimes below) after a few seconds of omxplayer use ? I have never noticed that (but I have never checked). Maybe it's related to my omxplayer's freezes issues... |
|
This is normal behaviour for any program that does lots of file I/O. |
|
Can you test this libbrcm_host.so ? |
|
No more message ! (And thank you @P33M for your answer, sorry I missed it) |
|
I think the belief is still that the kernel warning is harmless, so this fix probably won't be related to the freezing. |
|
Freezing just occurs, and dmesg shows thoses messages: After 22 hours of non-stop video playing. |
|
Can you add Also can you confirm you are up to date? (e.g. |
|
vcgencmd version Uname -a Rebooted with start_debug, now waiting... see you later, thank you for help |

Are you using the most recent Raspbian? If not what are you using? |
|
I guess the first question to ask is does this still happen on the latest Raspbian? Seems that Minibian hasn't been updated for a few years (in the links I saw), although you must have updated the kernel fairly recently. |
|
Also, reading your logs, I suspect that the latest error is actually different from the original one. The latest logs show an error in the h264 system somewhere. What sort of videos are you playing back, and how do you schedule them? Is this some sort of billboard system? We do have a lot of customers who do that sort of |
|
I haven't tested on raspbian since several months, so I don't know... But there was the issue on the last raspbian I tested. Videos are most of the time mp4 h264. It's indeed a billboard system with, to simplify, a simple php script playing a playlist of videos like this: |
Uh oh!

Hello
as said in a previous closed issue #253 I get some odds messages with dmesg when a plug the hdmi cable:
To reproduce this error you can download a complete minibian image here:

(login root / raspberry)
Tested on pi3 with 2A power supply, and this screen:
https://www.amazon.fr/gp/product/B01FFAAZRC/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
Just plug and unplug hdmi cable...
There is a small video loop starting at boot, but I'm not sure this is related to the issue.
Note that that this issue seems to have no effect, but well... may be this is just a part of an iceberg.
Thank you !
