Swipe to next event for the same monitor id not working

[abishai]

I migrated to 1.30-rc1 ZM and I'm running FreeBSD, so I suspect ZM devs will ignore me :) I hope, you can shred some light on the matter.

I viewing events from timeframe page. Gapless playback works like a charm, however when I swipe to next event, the original event starts from the beginning.

syslog: Jun 17 22:37:38 zm zms[2870]: ERR [Unable to send raw frame 13: Broken pipe]

broken pipe is common error for me, it pops up when I close any stream from web - montage, event playback and so on. I don't know the reason, but it looked harmless enough to be ignored. Looks like socket closed while ZM still writing stuff to it.

I don't beleive I can figure out how to fix it myself on ZM side, can some additional checks be implemented on ZMNinja side to ensure the next event starts? Looks like ZMNinja scared a little :)

The "Internal Server Error" is an Apache error, not zmNinja, so not sure what I can do - zmN uses zms POST commands to change events (via the web server)

• checking on my install of 1.30

[pliablepixels]

Just checked - I'm not seeing any issues (There are times it fails, but its not 500 - its timeout - can't do much there - zms doesn't respond - its flakey)

[abishai]

"command":"13" is the next event command? Is there command to stop stream first and then request new? Because, gaplsss event works somehow.

[abishai]

Or try to repeat the same request if it fails. Looks like zms simply dies when it stops before all frames fetched.

[pliablepixels]

So interestingly, gapless does not require a command to be sent to move to the next one - if you start the stream with mode=gapless zms will keep moving to the next ones (as opposed to mode=single) --> thats why it keeps working - one the command is set, it doesn't need updates.

Swipes on the other hand send POST commands. Yes, there is a command to stop https://github.com/ZoneMinder/ZoneMinder/blob/66a3fef61ebd10c45968a3706021d45d027e28be/src/zm_stream.h#L60

[pliablepixels]

And yes, I can probably try harder at zmNinja to make these commands work. I'll take a look the week after next --> I am on travel till Thu.

[abishai]

Looks like zms really throws error when it stops before all frames are fetched. This can be hard to find. I'll try sniffer to get additional information.

BTW, I enabled ZM debug and found strange POST from ZMNinja every time it start event playback. The first request contains no eventid.

Not related to original bug report, but curious.

[abishai]

BTW, is for zms powered event playback controls work? Pause, fast forward, fast rewind and playback scrollbar looks dead, without and errors from ZM.

[abishai]

Ahh, commands are processed by PHP ? So, it's web server answer? I can debug that then. Maybe some silly configuration error was made.

[abishai]

Right,configuration issue. Sorry for false alarm. But, my ray of hate goes to person put @ in socket functions. Was a socket but MUTED (arrr) issue

[pliablepixels]

no problem - glad you resolved it.
