For anyone who is wondering why the single-stream URLs that you are using from your BI web server have been crashing your BI, they seem to have broken that functionality in the last few releases.
My single stream URLs that I was using e.g. http://192.168.1.*:82/mjpg/Cam5/video.mjpg&user=username&password=password
started crashing BI. Regardless of how I was accessing (through a web browser or through actiontiles).. it just crashed it every single time.
The BI version I was using was 126.96.36.199. This is the latest release from the 2nd of May 2020. I reverted back to a release from April 188.8.131.52 and it works again.
I recently updated my streams and BI to support sub-streams to control the CPU usage, It seems like the new release had some improvements for the webserver and they inadvertently broke previous single camera stream functionality. THe new release has very good improvements for when you access BI through the main server URL and port.. it would stream substream and transcode to the main stream so you get the best of both worlds through the webserver.. i love that, however it broke my much needed single stream URLs that I love seeing on actiontiles.
Anyway, long story short, if you are confused about whats going on, I found the bug.
I have now emailed support informing of this bug and I would urge you all to do the same so that we can get single stream URLs working again for action tiles.
