text frame 'Unable to stream' in 1.35.23

[muebbel]

If i use ffmpeg with decoding enabled everything works, but if i disable decoding i get a image with "unable to stream".

I cant find the source for the problem, only some logs which tells "there is a problem":

Any suggestions to solve this?


UPDATE
If i change the function from "nodect" to "record" the captured video is correct saved and playable... only the live-view wont work (doesnt matter if nodect or record).

I find changing the source type restores live view.

E.G., Ffmpeg -> Libvlc -> Ffmpeg (with decoding enabled) restores the stream. Scary stuff.

Yeah, like i telled, if u enable decoding, its working fine...but with the known CPU usage...

[iconnor]

If you want to view the image you have to decode (for now).

[muebbel]

OK, thx for this important info

Is there any timeline or something to add the "no-decode-view"-feature?

[compsol]

I don't have an option for ffmpeg decode, is there another place in the config to enable this.

my list has:
local
remote
file
ffmpeg
libvlc
curl (http(s) only)
web site
nvsocket
VNC

On other "tabs" i have several options for ENCODE. but nothing anywhere for DECODE

Same model camera is working on my 1.28 zm machine just fine.

[compsol]

UPDATE:

removed database and switched out mysql for mariadb and ran zm_create and added user.
added camera again and this time I have working live view for both thumbnail and montage.

events have quit working now but I think it may be permissions from not deleting the events folder from the previous database.

I also am not sure what you mean by "with decoding on", and I'm having this same problem with an Annke 6MP camera. I tried switching to libvlc and back (even restarted zm each way) but no luck. Any advice is appreciated. I have my recordings but can't live stream in browser or zmninja. It worked when I first set it up, but a month or two later it just gives the unable to stream error on a black screen now. I have similar log entries.

[SBCDave]

Bump. Hoping for info on how to turn on decoding. Thanks for any help

[muebbel]

This threat was created to get a info for "how to view videos from cams without the need of enable decoding" and now here are questions about "how to enable decoding"...

The option to view the cams WITHOUT decoding the stream will give a great benefit to ZM (much less CPU usage) if the cams can trigger a userdefined cmd on a alert.

I hope we will get this feature soon.

Might be better posting a new thread in the current Dev version 1.37.

Don't post a thread unless you are willing to fund it.
