adding a second camera, impossible

problem : can only have 1 camera at a time.
when trying to add a camera, log shows that cannot prime, and keeps trying without success.
the first camera continues to be captured without problem.

Environment :
raspberrypi 3B+ with raspbian "buster"
zoneminder 1.32.3 "followed the steps from the wiki"
camera : 3 cams, brand: digoo, model: BB-m1
source used = ffmpeg
path = rtsp:user:password@ip:554/user=[user]_password=[password]_channel=1_stream=1.sdp?real_stream

ps: stream 1 yield a 640x360 signal , verified via ffprobe commands.

increased /dev/shm to 2G but is not used much (few percent).
options-storage changed to point at a 1T usb-drive for all events

Load steady at less than 1.00.
with the commands ffprobe .... i get sometimes the following message " [h264 @ 0x17adbe0] concealing 416 DC, 416 AC, 416 MV errors in P frame"

Um /dev/shm is a ram drive. It can't be larger than available ram....

I note also that your URL is rtsp:user:password...

If that's not a typo, it must be rtsp://user:password...

Thanks for doing that thread, I tried assembling a first camera set and it didn't really go as I planned... Plus, I'm trying to do something that'll allow me to watch over the one of these houses in Greece I'm planning to buy next year while I'm not there, so I'll definitely need a multiple camera network.

Hello,

i thought, i am the only one... i do have the same problem like OP (same error messages etc). It's weird because using the same setup (4 dahua ip-cams via rtsp) with Zoneminder 1.30.4 it just works fine. Using Zoneminder 1.32.3 I can use 1 rtsp at a time only.
