Original Assignee: Felipe Cecagno

When the user unshares a webcam, the event "user_unshared_webcam_message" is being put twice into redis. Both events are very similar but are not exactly the same. The differences are that the first one has an empty "stream" attribute and the timestamp is updated when the second event is generated.

Example:

"bigbluebutton:from-bbb-apps:users" "{"payload":{"stream":"","userid":"ktgqbumup9na_2","recorded":false,"meeting_id":"05a1651bfda0d05f059940395de7cb68adf1b0d2-1453315706895"},"header":{"timestamp":1393534715,"name":"user_unshared_webcam_message","current_time":1453316789603,"version":"0.0.1"}}"

"bigbluebutton:from-bbb-apps:users" "{"payload":{"stream":"medium-ktgqbumup9na_2-1453316690923","userid":"ktgqbumup9na_2","recorded":false,"meeting_id":"05a1651bfda0d05f059940395de7cb68adf1b0d2-1453315706895"},"header":{"timestamp":1393534728,"name":"user_unshared_webcam_message","current_time":1453316789615,"version":"0.0.1"}}"

I was unable to reproduce this scenario. Tested on Ubuntu 14.04 LTS, 64-bit on Firefox 44.0.1 and Google Chrome 48.0.2564.109. There was only one message for user user_unshared_webcam_message that had the "stream" attribute:

@bigbluebutton:from-bbb-apps:users" "{\"payload\":{\"stream\":\"medium-onorvg9rkb6d_2-1455567700831\",\"userid\":\"onorvg9rkb6d_2\",\"recorded\":false,\"meeting_id\":\"40bd001563085fc35165329ea1ff5c5ecbdbbeef-1455564961728\"},\"header\":{\"timestamp\":346835922,\"name\":\"user_unshared_webcam_message\",\"current_time\":1455567704636,\"version\":\"0.0.1\"}}@

Could you provide more details on how to reproduce this issue?

I have tested this scenario in the 0.8.0 version and this no longer happens.
