Tim Schneider 2c76f03fe2 rpicamsrc: Added "src->started = FALSE;" to gst_rpi_cam_src_stop 
Makes the element reusable multiple times after a state change back to READY.

/**
* SECTION:element-rpicamsrc
* @title: rpicamsrc
* @short_description: Raspberry Pi Camera Source
*
* Source element for capturing video from the Raspberry Pi camera module.
*
* This element works the same way that the `raspivid` command-line utility
* does and has a similar feature set.
*
* The element can output video in form of raw video frames or encoded as
* (M)JPEG or H.264 video. You can use the element properties to fine-tune
* the capture, image processing and encoding parameters.
*
* ## Example pipelines
* |[
* gst-launch-1.0 -v rpicamsrc preview=true ! fakesink
* ]|
* should show a preview window on the screen.
*
* |[
* gst-launch-1.0 -e rpicamsrc bitrate=1000000 ! h264parse ! matroskamux ! filesink location=test.mkv
* ]|
* should produce a file called test.mkv containing an H.264 video stream. We
* pass -e to gst-launch-1.0 so that the pipeline is finalised properly when
* interrupted with Control-C. This makes sure the Matroska file headers are
* updated when streaming ends.
*
* |[
* gst-launch-1.0 -e rpicamsrc bitrate=5000000 num-buffers=500 keyframe-interval=30 ! h264parse ! splitmuxsink location=video%02d.mov max-size-time=10000000000 max-size-bytes=1000000
* ]|
* Records a video stream captured from the Raspberry Pi camera module and
* muxes it into ISO mp4 files, splitting as needed to limit size/duration to
* 10 seconds and 1MB maximum size.
*
* gst-launch-1.0 -e rpicamsrc ! image/jpeg,framerate=1/1 ! multifilesink location=image-%05d.jpg
* ]|
* Captures a stream of JPEG images from the Raspberry Pi camera module at
* a rate of 1 frame per second and writes each frame into a new file in the
* current directory, starting with image-00000.jpg, then image-00001.jpg etc.
*
* Since: 1.18
