 ## Troubleshooting
 
+<a name="jsmpeg-troubleshooting"></a>
+
+### JSMPEG live camera only shows a 'spinner'
+
+**Note:** As of 2021-09-12, no released version of the [Frigate
+integration](https://github.com/blakeblackshear/frigate-hass-integration)
+supports JSMPEG proxying. That functionality is already merged, and will be in
+the release *after* (not including) v2.0.0. The `frigate-jsmpeg` live provider
+will not work with earlier integration versions.
