regression on BOSON (640x512) camera support

[bvacaliuc]

Recent code broke the BOSON camera. The pipeline is generating a 1280x720@15fps pull from the camera instead of 640x512@30fps and scaling+rate adjustment.

reverted master and created https://github.com/uvdl/camera-streamer/tree/fix/issue5 to resolve.

Issue appears to be in the source framerate selection code:

VIDEO_DEVICE=/dev/cam2 FLAGS=debug,h265,xraw,scale,udp ./video-stream.sh
...
TRANSFORM xraw /dev/cam2 NV12 640 512 {
./video-stream.sh: line 539: { : syntax error: operand expected (error token is "{ ")
DEBUG qmst@dev=223
NO Audio encoder available
./video-stream.sh: line 655: { : syntax error: operand expected (error token is "{ ")
  ! omxh265enc bitrate=1400000 iframeinterval=18 ! "video/x-h265,stream-format=(string)byte-stream,width=(int)1280,height=(int)720,framerate=(fraction)9/1" ! h265parse ! queue max-size-buffers=0 max-size-bytes=0 max-size-time=223000000 min-threshold-buffers=1 leaky=upstream ! rtph265pay config-interval=10 pt=96 ! mux.sink_0 rtpmux name=mux ! udpsink host=224.1.2.5 port=5600 multicast-iface=eth0 auto-multicast=true ttl=10

Which fails to generate a source or transform pipeline.
