Recently I have bought an RaspBerry Pi Model B+ with a camera module and a Wi-Fi USB. It's all working pretty fine and no problems untill now.
I'm using GStreamer to stream my video. But I also have a PIR motion sensor module to track motion.. (the line i execute for Gstreamer to work:
raspivid -t 999999 -h 720 -w 1080 -fps 25 -hf -b 2000000 -o - | gst-launch-1.0 -v fdsrc ! h264parse ! rtph264pay config-interval=1 pt=96 ! gdppay ! tcpserversink host=192.168.178.31 port=5000 &.
When there is motion I want to capture it using the camera. I have written a python script that does this job.
The problem is that when I run GStreamer and I try to run the python script at the same time the python script crashes with the following error:
pi@raspberrypi /cctv $ sudo ./detectMotion.py mmal: mmal_vc_component_enable: failed to enable component: ENOSPC Traceback (most recent call last): File "./detectMotion.py", line 18, in <module> cam = picamera.PiCamera() File "/usr/lib/python2.7/dist-packages/picamera/camera.py", line 379, in __init__ camera_num, self.STEREO_MODES[stereo_mode], stereo_decimate) File "/usr/lib/python2.7/dist-packages/picamera/camera.py", line 505, in _init_camera prefix="Camera component couldn't be enabled") File "/usr/lib/python2.7/dist-packages/picamera/exc.py", line 133, in mmal_check raise PiCameraMMALError(status, prefix) picamera.exc.PiCameraMMALError: Camera component couldn't be enabled: Out of resources (other than memory)
I'm running my RPi with Raspbian (Linux raspberrypi 3.12.28+ #709 PREEMPT Mon Sep 8 15:28:00 BST 2014 armv6l GNU/Linux)
