Raspian h.264 to mjpg problems

[k1rk]

Hi together,

it´s my first post here. I tried the search and also found some threads but nothing helped so far.

I run a Raspian as a virtual machine on an i7 system (I reserve 1 core and 1,5GB Ram).
VLC is installed.
To convert the stream from my Ubiquiti Unifi G3 dome camera with the following settings:

RTSP URL:
rtsp://10.0.0.xx:554/s2
Width:1024
Height:576
Bitrate:2000 kbps
FPS:30

I use the following command:

Code: Select all

cvlc -I dummy -v -R rtsp://10.0.0.xx/s2 --sout='#transcode{threads=2,acodec=none,vcodec=MJPG,vb=2000,width=1024,height=576,fps=20}:standard{mux=mpjpeg,access=http{user=xxx,pwd=xxx,mime=multipart/x-mixed-replace; boundary=--7b3cc56e5f51db803f790dad720ed50a},dst=:8080/cam.mjpg}' --sout-keep

and get the following errors:

Anyone an Idea what I´m doing wrong and how to fix the problem?
I already played around with some settings but so far no solution...

Thanks in advance!

interesting thing... with setting vb=2200 or above it seems to work.
lets see how long

[k1rk]

the rc buffer underflow error is gone and the stream works for around a minute. after that it stops and the message appears:

[00007f1e7c000d18] core stream output warning: trying to send non-dated packet to stream output!
[00007f1e7c000d18] core stream output warning: trying to send non-dated packet to stream output!

Please help!
