We observed the bad video quality in one-way screen sharing case with latest JVB. The use case is,
- Moderator shares his screen
- Participant joins the room to get moderator’s screen
- No audio
Only moderator shares his screen, there can be many participants in the room.
With the new JVB (April 1st version and commit c5b5f463 on Feb 19), we observed some video artifacts (please refer the attached screen shot, and pay attention to the fuzziness around the number
However, with old JVB (last Oct 18 version e8cc9d3c6736eecbb437c8f53ad0977a899654a5), we did not observe the artifacts.
You can observe the issue with following site.
Please click the vertical three dot at the top right to choose different versions, the prod (Default) is for version of Oct 18), the pruc-xmpp-as-a-001.555.comcast.com is for version of c5b5f463 on Feb 19).
We use online stop-watch to start a stop watch and observe the behaviour (share the screen of stop watch page)
Any idea what change causes the artifacts?
