hi,

I've got I-Tuner Spectra8 card to play with and I'm having 2 problems with 1.19.2.

1) I'm only able to get cameras working on zoneminder side when I set source resolution to 320x240 and use the YUV422P palette. Spectra should support resolution up to 768x576 but then zmc refuses to work with any palette given. "Failed setting the window attribute" is the error I see in syslog. Tryed to increase the debugging verbosity by setting ZMC_DBG_LEVEL_zmc enviroment variable to higher values than 0 and execute zmc then - that didn't work. So how to increase the debug verbosity? And why I don't get other (and supported by hardware) resolutions - I do have ZM_STRICT_VIDEO_CONFIG set to 0, otherwise it did't work at all (even with 320x240).

2) Problems with montage window - with mozilla 1.5 or 1.6 (not using cambozola) I get 2 camera streams out of 8 cams - all others are broken images, stills link doesn't seem to work at all.
With IE and cambozola I get some 5 cams streaming out of 8 - but pictures are crappy. Should it be possible at all to view some 8 cams within montage window or is it too huge task for http protocol?


Here is the outout from zmu -d 3 -q -v:

Hi,

A couple of things.

1) Have you set up your modules.conf to pass appropriate Spectra options to the bttv driver?
2) The simplest way to increase debug levels on a running process is to send it a USR1 signal. If you want high debug from the start then adding a zm_dbg_level = x; line before the zmDbgInit(); call.
3) The stills montage view was a bit broken in 1.19.2, it's probably worth going to 1.19.3 if you are going to use this.
4) When you say pictures are 'crappy', can you elaborate or post a screenshot? Are you using jpeg or mpeg streaming? You should be able to get 8 cameras in this view provided the update rates are not too high.
5) You should be able to use the Spectra card with almost any resolution and palette. Do you see any other errors in the messages log?

Phil,

1) yep I have modules.conf options set for spectra - options bttv card=42,42,42,42 tuner=4 radio=0 chroma_agc=1 vbibufs=4 v4l2=1 gbuffers=16

2) I'll try that

3) Updated to 1.19.3 and there are improvements on that montage view problem - with forcing cambozola I get correct view on all 8 cams, both IE and mozilla (mozilla thou needs sometime window refresh when displaying some cam feed double or triple replacing the right ones).
But when not using cambozola with mozilla - it's still displaying 2 out of 8, others are broken.
Sometimes these are 1,2 cams - sometimes 2,3. Stills link is also then unresponsive.

4) Now cambozola 0.22 works fine with 1.19.3

5) I can see some errors. For example switching device 3 channel 1 to 768x576 YUV422P I get
in syslog:
------------------------------
camserv zmc-d3[27548]: INF [Debug Level = 0, Debug Log = ]

in zmdc.log

zma -m 8' crashed at 04/05/07 13:54:54, exit status 255
------------------------------

Ok - got it work , increased the shared memory limits as in FAQ.
But there are still some picture mocups when trying palettes other than grey...gotta test it more to see if there is a rule...

Seems that both same device channels have to be configured likewise - or you get strange pictures...

Turned all cams to capture 768x576 Grey at 5fps - now I see in syslog a lot of this stuff:
