obs-gstreamer 0.3.5

- Fixed some small bugs I think
- Accept RGBx and BGRx color formats
- Experimental prebuilt plugins

The prebuilt libraries are untested. If they don't work for you, please try to figure out why and report. I suspect there may be problems with dependency libraries to be found on the target system as they may be located on different ones as on the build machine..
- Add option to keep pipeline running when hidden
- fix video stride when row bytes are greater than width
  • added option to set sinks to sync=false
  • added option to restart pipeline after error
  • clear data when pipeline not running (fixes freeze frame)
