Are you out of RAM? I find x264encode to use a lot.

Posted: **Sat Nov 11, 2017 9:32 am**

No i don't think

/dev/shm 31%

total used free shared buff/cache available
Mem: 8131876 2314352 1763244 1849920 4054280 3610948
Swap: 12537852 611292 11926560

Crash only when i use crf
i can choose X264 encode, but if i change quality he crash just for second camera

If the first camera is disabled does the second one work?

No just first camera in list, first ID can have a crf option

other crash even if alone

Sounds like it's a problem with that specific camera then. I'd look into any setting you can change on the camera itself. What camera is it? Is it the same as the camera that works?

Posted: **Mon Nov 13, 2017 10:36 am**

Yes all same camera

ESCAM QD300

That camera outputs h264. Why not just use h.264 passthrough instead of trying to re-encode it?

Posted: **Mon Nov 13, 2017 2:45 pm**

Yes

can i use option CRF for h.264 passthrough ? for reduce quality and weight

I wan't use X264 encode just for reduce quality and weight but if i can reduce with h264, i use h264

Thanks for your help

Ah, I see. No, passthrough just passes through. You could change the settings on the camera to the quality you want. Using passthrough saves a lot of cpu usage.

So if you really want to use x264 encode then we're back to camera settings. Since the one camera never works it's not from having 2 streams. Check to be sure camera 2 has the same video settings as camera 1 on both zm and the camera itself.

Yes same setting on all camera

I think it's bug with threading process

But why just first camera is ok, i don't know ...

But after try different setting if you choice X264 encode with no option CRF all is ok on all camera and weight of mp4 is less

So in h264 passthrough, view storage event in LTE gsm is no possible, very very long
But with X264 encode only with no option CRF view storage event in LTE gsm is good

So all is ok for me

Thanks for your help

What's interesting is that the crash is happening in zmc, which doesn't do the x264encode. zma does. Looks like it is dying in ImageAnnotate, which is called to write time on the image. So this has nothing to do with X264encode.

What type of monitor is this, ffmpeg or remote?
