Pi Zero W Support

[joejoethejoey]

Is it possible to run displaycameras on a Raspberry Pi Zero W?

Would only need it for 4 cameras maximum.

Hi joejoethejoey, Yes, you can display 4 cameras using Raspberry Pi Zero W.

I have tested Raspberry Pi Zero W and able to display 8 (low resolution) RTSP cameras on 1920x1080 HDMI TV - using 3x3 display matrix.

Great! Thanks k3bonzo!!

Hi k3bonzo,

I've been trying to add extra cameras to the display. For some reason, no matter if I use 2x2 screen on 2 matrix or a 3x3, it will only display 6 cameras max. I'm using low resolution RTSP (640x360). I've checked all the code and it all looks correct to me:

# Window names `# 3x3 screen with 1 off-screen windows` `windows=(upper_left upper_middle upper_right center_left center_middle center_right lower_left lower_middle lower_right `off_screen)` `# Make sure to account for each window above in the list below.` # Windows positions `window_positions=(` `#First Row` `#upper_left` `# 640x360` `"0 0 639 359" \` `#upper_middle` `"640 0 1279 359" \` `#upper_right` `"1280 0 1920 359" \` #Second Row (missing all but the far right window because large_left is double size #center_left # 640x360 "0 360 639 719" \ #center_middle "640 360 1279 719" \ #center_right "1280 360 1920 719" \ `#Third Row` `#lower_left` `# 640x360` `"0 720 639 1079" \` `#lower_middle` `"640 720 1279 1079" \` `#lower_right` `"1280 720 1919 1079" \` `)` # Camera Names camera_names=(cam1 cam2 cam3 cam4 cam5 cam6 cam7 cam8 cam9) # Make sure to account for each camera above in the list of feeds below. `# Camera Feeds` camera_feeds=( \ # Low-Res #cam1 "rtsp://192.168.1.XXX:XXX/5cdd5849d36e93XXXa5e71d_2" \ #cam2 "rtsp://192.168.1.XXX:XXX/5cdd5849d36e93XXXa5e71d_2" \ #cam3 "rtsp://192.168.1.XXX:XXX/5cdd5849d36e93XXXa5e71d_2" \ #cam4 "rtsp://192.168.1.XXX:XXX/5cdd5849d36e93XXXa5e71d_2" \ #cam5 "rtsp://192.168.1.XXX:XXX/5cdd5849d36e93XXXa5e71d_2" \ #cam6 "rtsp://192.168.1.XXX:XXX/5cdd5849d36e93XXXa5e71d_2" \ #cam7 "rtsp://192.168.1.XXX:XXX/5cdd5849d36e93XXXa5e71d_2" \ #cam8 "rtsp://192.168.1.XXX:XXX/5cdd5849d36e93XXXa5e71d_2" \ #cam9 "rtsp://192.168.1.XXX:XXX/5cdd5849d36e93XXXa5e71d_2" \ ) ` # Are we rotating cameras through the window matrix? (default false if not set here) #rotate="true"`

Hi joejoethejoey,

Your layout declare 1 off-screen in 'windows=(........ off_screen), but you not define off_screen position point in 'windows_position ( ........... ). After # Third Row ...... ...'

I use 3x3 screen with 3 off_screen position, find attched layout for 8 cameras in 1920x1080 that works for me.

layout.conf.1920x080.3x3-8cams.txt

Thanks k3bonzo for your reply. My bad, I forgot to edit the off_screen cam off the code posted previously. My actual code doesn't have that. Either way though, it still only displays 6 cameras. I've also tried the layout you linked. The third row doesn't show anything. Any other ideas?

Thanks again!

[joejoethejoey]

I've been using the code for a few days now. I've noticed that it still only displays 6 cameras, but it randomly chooses to display a different set of 6 cameras. Originally it was only cameras 1-6. For the last 2 days, it's been cameras 2, 3, 5, 6, 8 and 9. Could it be a ram issue in the Pi Zero?

Memory split setting on my raspi Zero W is 256MB

[joejoethejoey]

I have set the same. Is it worthwhile increasing to max 512MB? Is there a way to increase incrementally to test rather than start afresh?

Thanks!

Yes, with rpi-config.
