Hi everybody, I've looked across the board but I can't find a way to get a couple of Panasonic cam (to be precise a WV-NS320 and a WV-NW470) working with ZM

I'm running ZM 1.22.2 on a gentoo system and with my configuration zm is fully functional with:

Local analog cam on a BT878 board
Axis 214PTZ (network cam)
Panasonic BB-HCM381, BB-HCM331 and BL-C10 (same cgi protocol, all IP cam)

What I've tried:
- wget is working

Code: Select all

wget --save-headers -S "http://user:pass@IP/cgi-bin/push?CH=1&UID=661&MODE=START&FRAMERATE=10"

with it I receive a "stream" like:

Code: Select all

HTTP/1.0 200
Content-type: multipart/x-mixed-replace;boundary =--myboundary

--myboundary
Content-type: image/jpeg
Content-length: 6606
..
..
..
--myboundary
Content-type: image/jpeg
Content-length: 6581
..
..

- switching the ZM_NETCAM_REGEXPS on and off
- switching the ZM_HTTP_VERSION on and off
- increasing the ZM_HTTP_TIMEOUT parameter up to 5 secs (with wget the cams are quite responsive)

In every case running zmc results in a log like

Code: Select all

Any suggestion? I'm running out of ideas.. I hope I've provided enough information..

Thanks in advance

ps (for jameswilson): I've seen a thread with similar problems you had with an IQEye cam (or something like that): did you succedeed to make it work?

This may be an issue with ZM not always sending the correct line endings. I have fixed this in 1.22.3, which will be out Thursday at the latest. This thread, http://www.zoneminder.com/forums/viewto ... =http+line, explains further and describes a fix.

Thanks a lot, yesterday I got to the same fix (looking at wget's requests that were working) and now I read your reply just before posting it!

Meanwhile I discovered another issue with these Panasonic cams: when in multipart-jpeg mode, they send an header like this (i used * for relevant " " chars):

Code: Select all

HTTP/1.0 200 <-- "OK" missing
Content-Type:*multipart/x-mixed-replace;boundary*=--myboundary

--myboundary
Content-Type:*image/jpeg
Content-Length:*12345
JPEG DATA

ZM doesn't like this kind of header:
when ZM_NETCAM_REGEXPS is disabled I got the error "No content boundary found in header", I think because of the " " char between boundary and "=".

when using the ZM_NETCAM_REGEXPS mode it complained about the missing HTTP status in the header. To get around this issue, I modified the regexp for retrieving the status from

Code: Select all

status_expr = new RegExpr( "^HTTP/(1\\.[01]) +([0-9]+) +(.+?)\r?\n",PCRE_CASELESS );

to

Code: Select all

status_expr = new RegExpr( "^HTTP/(1\\.[01]) +([0-9]+) *(.*?)\r?\n",PCRE_CASELESS )

but can't find a way to make the regexp

Code: Select all

snprintf( subheader_pattern, sizeof(subheader_pattern),"^((?:\r?\n){0,2}?(?:--)?%s\r?\n.+?\r?\n\r?\n)",content_boundary);

match the rest of the header, I think because of a missing blank line between the Content-Length line and JPEG data..

I will keep on trying to make zm working with these cams, but if you have an advice you are really welcome!
