no monitors at all - shared memory error

nuck · Post by **nuck** » Tue Feb 17, 2009 5:10 pm

I pulled down zm-1.24 from svn late last night. Seemed to build and install fine but I can't get any monitors to work. I have the monitors configured as V4L2, 320x240, NTSC, grey scale. I tried V4L1 to see if that would work but got no joy there either.

I'm stumped.

What version of ffmpeg should be used to build zm-1.24 at it's current status? I was using a release from Feb 10th 09

Just put a SVN Live CD together today with the patch for ffmpeg, seems to work fine on 8.10 for me. What kind of devices are you trying to use? Maybe I missed that part somewhere, but all the devices I've plugged in so far are v4l1 and work.

The only problem I was running into with the original release was when I was trying to multiplex inputs. I had a working setup with the 1.24.0 release. Nothing seems to want to work with svn-2766.

LMLBT44 card with X10 b/w cameras. Nothing fancy.

I'm starting to wonder if I shouldn't be installing yet another "newer" version of ffmpeg. I'm pretty sure the version I have installed is svn-17125 but I'm not 100% sure of that.

Ok, I pulled down and installed svn-2775 tonight. No noticeable changes from what I can see as far as any monitors I set up not working.

Here's a debug log -

Perhaps I may be I'm going senile but I have to ask. Early on in the setup process it says "Loaded Monitor 1" and when it finally errors out it is saying "Failed to capture Monitor 0 image". Am I seeing things, or just not understanding what is going on here?

Not at all concerned about the "Unable to map file /dev/shm/.zm.mmap.1" at the moment. The file is there, zm created it, so it should be writeable. I was just tinkering and enabled mmap when I ran the last build.

In /var/log/syslog I'm seeing this -

Code: Select all

So call me a senile old old fart, but I know what I'm seeing and it's not making sense. What's with the references to monitor 0? /dev/video3 is the correct device.

Also, where zmwatch had been squaking about not being able to create memory space for the first monitor when I only had one monitor defined, I'd created a second monitor and now it's squaking about not being to create memory space for it. All in all, me thinks device numbering has been stomped on somehow, somewhere along the line.

Ignore zmwatch for now. The error message about monitor 0 is confusing and I was looking at changing it yesterday. It basically refers to the zeroth monitor that that zmc has to handle. If you have multiple cams on a card on the same input but on different channels then there may be several monitors that one zmc is looking after. In this case it just means the single one so that is consistent.

I think your issue is related to the cams being grey-scale. I will go check the code and run some tests here but in the meantime maybe you could try with a different palette and see if that makes a difference.

I have found a bit of a bug with greyscale monitors which I have now fixed and which will be up on the SVN a little later. I have also revisited the conversion area and removed format conversions where both formats are the same which might make a tiny bit of a performance improvement also.

I have also tweaked that error message bit to make it clearer.

Ok, thanks Phil. I'll have a look later on today after I've done my first round of snow shovelling.

I just installed svn-2778 and I have monitors back working again. I also have 2 channels functioning again. This is on a LMLBT44 card.

Congratulations Phil, and thanks.

The only issue that jumped right out at me is that when I first define a monitor I have to open the source config window (click on the device) and resave the monitor before it will enable (change from red). Perhaps if I were to wait long enough it may enable on it's own.

I'm not sure I exactly understand what you are referring to here but if perhaps you installed on top of a running ZM then it might take up to 15 minutes I think for the capture daemons to get restarted.

The normal behaviour is that is any daemon or process fails it is restarted immediately. If it keeps falling over then the restart gets progressively less frequent to avoid (a) clogging up the logs and (b) using systems resources on things that aren't working. The maximum delay is about 15 minutes I think. You can manually type

Code: Select all

zmdc.pl status

and it will list as pending any processes that are waiting to be restarted and at what time the next restart attempt is.

As a general rule I would recommend stopping ZM entirely before installing though.

No, I'd stopped ZM before installing. I've run into an install failing due to not being able to replace a running binary, so I know better.

Not a huge deal anyway. It's only a matter of clicking on the source and saving it again to get it to come alive. It's working which is all that really matters in the end.
