added audio and video codec names in telemetry report

now telemetry report has two new parameters, audioName and videoName. Both are arrays to save the AV codec name used in each call.
There is no other way in case we have to deal with old versions running out there. If installation were a clean on, the report would be the one created, but if installation is on a previous one, the old database will be used, report != null, and it would never be updated. Failing new parameters insertion.
