Issues with 1.24 release on Slackware 12.2

nuck · Post by **nuck** » Tue Feb 10, 2009 6:19 pm

As noted previously, I'm running into a snag with 2 multiplexed cameras. Sometimes they work, sometimes not. I don't really seem to be able to nail down anything specific.

For reference, I'm running on a Athlon 2400XP with 2 gigs of ram. I'm using a LMLBT4 card with 5 cameras, 2 of which are multiplexed on /dev/video0

Here's an excerpt from zmdc.log

and on, and on......

I've also noticed that my system is running slower than the second coming. Checking with top I see -

Should I expect to see this kind of cpu usage for zma and zmc? I've seen the cpu usage hit close to 45% for both on a forced alarm.

Suggestions??

Check what is in your syslog, maybe /var/log/messages I don't know on Slackware.

CPU use varies depending on how things are configured but I would suggest getting things working first but your CPU does seem high. There is a FAQ on CPU use in the Wiki which is probably worth having a look at.

Does this tell you anything?

Doesn't do much for me other than telling me that zmc is seg faulting for some reason and it appears to me as though what's happening is zmc crashing when it is starting on /dev/video0 on the second channel. I'll fire it up later tonight with the debugging cranked up and see what it has to say.

I'm running pretty much the exact same setup I use with 1.23.3, but I'll have a read later and see what I can find. I'm not seeing much over 8-9% cpu total usage on all instances of either zma or zmc combined with 1.23.3 at the moment.

Typing

Code: Select all

addr2line -e /usr/bin/zmc 0x8061596 0x806947f 0x804d06e

can sometime give some useful information. Failing that, stop ZM and then (probably as root) type

Code: Select all

gdb /usr/bin/zmc
run -d /dev/video0
<wait>
bt

If you think it may be V4L2 related you can configure monitors to use V4L1 instead so that might be worth a try.

I got it.... What is happening is when I go to define a new monitor (the first time) as V4L2 the list box of device formats is only giving me the protocols for V4L1 and I've been selecting NTSC and then selecting grey for the palette. That setup was failing (of course) so I then selected V4L1 (not knowing that I wasn't seeing the full list of options available for V4L2) which is crashing when multiplexing the inputs.

When I went back in to redefine the monitors as V4L2, I got the full list of protocols as well as palette choices. I don't know if it is something peculiar to my system or not but I think I stumbled onto a bug.

Otherwise, all is good now or seems to be. Funny how it's always what you inspect and not what you expect...

All that said, what I am seeing when I first define a monitor with the default V4L2 selected, under the device format options I get the choices of undefined, PAL, NTSC, Secam, Auto FMT4, FMt5, FMT6 and FMT7 and under the capture pallete drop down I'm getting the choices undefined, grey, rgb24, rgb565, rgb555, yuv422, yuyv, yuv422p and yuv420p. If I switch from V4L2 to V4L1 and then back to V4L2 I then get the more extensive list that corresponds to V4L2.

Seems all is not well afterall. I can get a monitor working with V4L2 on /dev/video0 but if I add a monitor on the second channel I lose both monitors. But no crashes, so I thnk progress has been made.

Just for the giggles, I fired up gdb and here's what I got with 2 monitors configured as V4L1 (which seems to be causing the crash).

The program is running.  Exit anyway? (y or n)

With the monitors set up as V4L2 everything checks out fine with gdb.

I tried mutplexing on /dev/video1 and the result is the same. ZM indicates all is well with green labels but the frame rate is 0 when I view either monitor. I checked both channels with xawtv and I can select either channel fine. I've even gone so far as to define a monitor on /dev/videox channel 1 and left channel 0 undefined and it's working ok. Seems as though simultaneous access is where the problem lies.

Here's a copy of my /var/log/messages right after starting up ZM. The trouble spot I'm seeing begins with zmdc[5478] @ 02:29:56 (monitor 2 /dev/video0 0) and continues through setting up monitor 8 (/dev/video0 1).

Last but not least, here's zmdc.log right after zm startup

And on that note, I've had enough for tonight.

Thanks for all that. There are a few things there I can look at. Have you tried just defining both monitors to be V4L1 and seeing if it still crashes?

I can confirm the broken behaviour on adding new monitors so I will fix that. I will look at the other issues also next.

Actually Phil, the crash only occurs when I have two monitors defined on the same port using channels 0 and 1 with V4L1. I was mistakenly configuring for V4L1 thinking V4L2 wouldn't work properly.

When I configure for V4L2, one monitor will work fine on either channel 0 or 1, but if I enable a second channel on a port I get nothing on either.

Ok. I did go through all this last week to check nothing was broken but I will go back in and have another look. Multiple monitors on one device are very fiddly as they break all the frame buffering optimisations in the driver.

I think I did mention it, but my appologies just the same for not persuing it further, earlier. I was happy to assume that V4L2 wasn't going to work for me and was, like most people typically do, looking for the easy way out.

If you come up with something and want me to try it out before putting out for general consumption pass it along. Being the free-loader that I've been to this point, it's the least I can do.

Can you confirm the exact device and channel settings you are trying to use? Is it just channel 0 and 1 on /dev/video0 or something a bit more esoteric?

Near as I can tell it's just channels 0 and 1. I initially setup the monitor on /dev/video0 and have verified that the problem moves to /dev/video1 if I make the change, so I'd assume (there's that word again.. ) it would do the same on either of the other 2 ports as well. I can use either channel 0 or 1, but not both channels simultaneously.
