Hi all,
We are developing a vision project on CIO based on IR camera and Labview environment. At the begining we try to figure out what our IR cam have capabilities about streaming. Inside of cam, there is a module called IP video server which is the following:
-http://www.sensoray.com/products/2453.htm
This module outputs below streams:
- RTSP over UDP (just H.264 encoding)
- UDP (we dont know in detailed protocol but gstreamer can stream this on windows)
- TCP ( we dont know in detail)
Also this module can stream video according to following encodings:
- H.264
- MJPEG
We want to achive H.264 via UDP, cause camera vendor said that, it has the minimum jitter like 70-80ms.
Our first attempt was by using gstreamer1.0 on windows (with complete install) we did stream H.264 via UDP. Also we did RTSP over UDP successfully.
Then we switched to CRIO (CRIO 9042) and studied on NI IMAQdx for acquiring image from this camera. However we could not find any example or forum topic about that. So our first question is that according to above scenario how can we acquire a frame or frames by using IMAQdx palette?
After IMAQdx, we went to gstreamer way on CRIO which has packages on NI linux repo that we successfully installed partially on CRIO: opkg install gstreamer1.0.
Also we did install some of the plugins of gstreamer like gstreamer-plugins-base and gstreamer-plugins-bad. After these installations we can call test video and play on a window on CRIO. But could not stream any frame from camera cause it requires gstreamer-plugins-good and gstreamer-libav. These plugins are not in NI repo, so we did find "good" in the angstrom repo and installed it from there. But gstreamer-libav (which includes codecs) could not find. Also we tried building them by using "make" but could not success. If we can install gstreamer on crio completely we can use it in our embedded project.
Our second question is how can we successfully install gstreamer completely with all plugins or which alternative we can use? Any sugestions?
Thank you.
