Re: ZM 1.32.3 and 1.33.1 - record MJPEG images

No...but actually the fact that there are only 1-2 core developers and the couple of others volunteer time to test and respond to the many forum requests....try to get to the bottom of everyone's problem.

So relax....I will look into your problem here because I have seen almost all of them.

Re: ZM 1.32.3 and 1.33.1 - record MJPEG images

Post by rockedge » Sat Apr 20, 2019 7:30 pm

can you see any recorded jpeg images in the events directory that corresponds to the recorded event?

I have as default storage /var/cache/zoneminder/events

Yes, recording jpegs (many and many jpegs, frustrating) work fine.

I confirm. In the folder there are many jpegs.
The strange is it's possible to play the stream, and record it in jpegs. But not possible to replay what recorded on jpegs.

My impression is the bug (if a bug) has not been still collected from ZM developers/testers since not frequent: only on ARM (X264 is not compatible on ARM, so Video writer is disabled on ARM) and on MJPEG cameras.

thanks

Re: ZM 1.32.3 and 1.33.1 - record MJPEG images

@rockedge, I have an update.

I installed VMware on my laptop (an Intel i5 6300U) and a fresh Ubuntu 18.04.
Then I installed ZM 1.32.3 following exactly the intructions/script at https://wiki.zoneminder.com/Ubuntu_Serv ... e_easy_way

So, for my MJPEG camera I'm able to replay the recorded streams if setting Save Jpeg = disabled and Video writer = X264 Encode (on this platform it is enabled)

if trying to set Save Jpeg = all possible values different from disabled and Video writer = disabled, I'm able to see all jpegs in /var/cache/zoneminder/events through the ls command, but I'm not able to replay the recorded JPEG images (exactly as it happens for the Odroid ARM board).

So it seems a bug on all platforms, not only on ARM. For platforms different by ARM it's not a big issue since there is a workaround: to use Video writer = X264 Encode (because enabled on all platform different by ARM); but on ARM platform is a roadblock.

I don't think it's an error of mine installing ZM since I exactly followed the instrctions/script mentioned above! :cry:

Is it possible none tested the case "MJPEG camera and Save Jpeg enabled" ??!?

It's a roadbloack for all owners of ARM boards (Raspberry, Odroid, ...) and MJPEG cameras. Not possible to replay recorded events on 1.32 and following versions! The only workaround -I found- is to go back 1.30.4 (probably the most stable version ever built), but that's unbelievable a regression on what already working well.
Please let me know. thanks

EDIT: moreover ZM 1.32 is able to generate a video from recorded JPEG images through the Video button. And then downloading the video it's possible to see it! So it seems ZM 1.32 correctly records jpeg images, but it's not able to view them clicking directly on the recorded event (note that it works in ZM 1.30.4!!).

When viewing a .mp4 we just send the .mp4 to the browser. WHen viewing jpegs we use the cgi program zms. If your cgi paths are not correct in apache config, then zms doesn't get run and you don't get to view the event. This is literally reported every day here. Which is why we have such a long detailed error message which every still doesn't read.

There should be a line in your apache config for zoneminder /etc/apache2/conf-enabled/zoneminder.conf ? That says

ScriptAlias "/zm/cgi-bin/" "/usr/lib/zoneminder/cgi-bin/"

If you are not using the /zm at the end of the url you can add another

ScriptAlias /cgi-bin /usr/lib/zoneminder/cgi-bin/

Hi Isaac, thanks for your answer.
I'm sorry but I cannot understand how hell for a fresh Ubuntu install and a fresh ZM install (according to the script provided on the wiki) I could modify the variables you are mentioning. And I have to be treated like a stupid.
Probably i'm a stupid newbie but you are forgetting the free spirit and the reason you started to develop ZM.

Anyway before disturbing you I already read the reccomendation at https://zoneminder.readthedocs.io/en/la ... untu-18-04 at chapter Socket_sendto or no live streaming

I have no issue on live MJPEG streaming, it is only on recorded JPEG (from mjpeg stream). Anyway:

First, the recommendation is valid for 1.30.4 since in 1.32 there is no more Paths sheet in Options.
Second, I found for 1.32 /etc/zm/conf.d/01-system-paths.conf (i hope i found the correct file) and I checked into it:

# ZoneMinder url path to the zms streaming server
ZM_PATH_ZMS=/zm/cgi-bin/nph-zms

I think it is correct.

In my /etc/apache2/conf-enabled/zoneminder.conf I have:

ScriptAlias /zm/cgi-bin "/usr/lib/zoneminder/cgi-bin"

note: without "" before and at the end of /zm/cgi-bin

I'm able to view and NOT able to replay mjpeg stream.

I receive the warn/error msg in the log console:

I tried too, as you suggested, ScriptAlias /cgi-bin "/usr/lib/zoneminder/cgi-bin"

i'm NOT able to view and NOT able to replay mjpeg stream :-(

I checked too the contents of /usr/lib/zoneminder/cgi-bin:

Code: Select all

odroid@odroidxu4:~$ ls -lh /usr/lib/zoneminder/cgi-bin
total 1.1M
lrwxrwxrwx 1 root root    3 Dec  8 17:06 nph-zms -> zms
-rwxr-xr-x 1 root root 1.1M Dec  8 17:06 zms
is that correct? I think yes.

if you want I could expose my board for your check.
I could pay for support.
thanks

Re: ZM 1.32.3 (and 1.33.1) - bug on replay recorded JPEG images

Post by rockedge » Sat Apr 27, 2019 10:26 pm

you know if I remember correctly...a while ago I could see a live stream...also record an event but i could not replay the event as an mp4 or jpeg.....I think I fixed it by finding out I was missing a library but I don't remember the specific one. I will try to recall what I did to fix it...I do remember it was a simple fix.

Re: ZM 1.32.3 (and 1.33.1) - bug on replay recorded JPEG images

Post by pat2 » Sun Apr 28, 2019 9:37 am

hi rock,

you touched the point!
Able to see the live MJPEG stream, but not able to replay the recorded JPEG images.
The only difference: in case of ffmpeg camera, I'm able to replay the mp4 recorded file.
It's not a matter of the specific path of nph-zms differently I should not be able to see the live MJPEG stream.

There should be a difference between the developers platform and a fresh platform.
Debugging on a fresh platform like I described (wmware, new ubuntu 18.04, LAMP, script on wiki) it should be easy to check the error. Unfortunately I'm not expert on this technology.

Please, if you will remember the library to be installed let me know. Not nly for me, but for other users in the same situation.
thanks

You are right, if live view works, the the zms path is correct.

Here's another thought: Is AUTH_HASH_LOGINS on? Options->SYstem->AUTH_HASH_LOGINS

I seem to remember a case where we weren't doing auth correctly without hash logins...

Are you using auth at all?

Please update to latest master, it has a lot of fixes since 1.33.1

Isaac, thanks for the answer.

Unfortunately AUTH_HASH_LOGINS is OFF.
I'm testing without AUTH at all.

I will try to install 1.33 from scratch and I will let you konow.

when viewing an Event you can play the mp4 but what are you doing to play the jpegs?

Can you use the Stills button to view the individual jpegs?

Post by pat2 » Sun Apr 28, 2019 8:30 pm

yes, confirmed.

Just installed the last ZM 1.33.6 on a fresh ubuntu 18.04 on Odroid XU4 (ARM processor).
Able to see the mjpeg live stream, not able to replay the recorded jpegs. Even if present the jpg files in /var/cache/zoneminder/events.

yes, I can replay mp4 when the source is ffmpeg.

when the source is mjpeg, since I'm on ARM platfrom, the only option is to save jpegs. and the image remains blocked.
i see the event with the thumbnail.

Interesting:
If I push Stills button, the first 7 x 14 +1 (=99) individual jpegs are grayed, the remaining (from 100 to 303) are correct!

I can scroll with >> and << buttons. The others buttons are disabled.

note: differently from 1.32.3, with 1.33.6 I'm not able to generate a video. It remains in "Generating video..." status.

thanks

the fact that you can not create the video is a sign something is not right. Does the export function work?
I seem to remember the permissions and ownership of some directories were incorrect which caused it....but this could also be something else...I ran into all kinds of problems figuring out how to install and run ZM on different Puppy Linux variations...and what you describe was one of them.
