[Telemetry] Media usage

[vesta0]

Description & Product Manager / Data Scientist User Story

• As a product owner, I want to know how often the browser is used to play media, so I can prioritize media related bugs accordingly.

What probes

New probes to track the following states:

Action	Item	Description	Works?
PLAY	state	Media started playing.	❌
PAUSE	state	Media playback was paused.	❌
STOP	state	Media playback has ended.	❌

Acceptance Criteria

• Event pings can be queried via re:dash
• We are sending telemetry events for the actions listed in the requirements
• We have documented the telemetry
• We have asked a data steward to review the telemetry
• NOT an AC: Data science to create dashboard or further graphs (this will be a separate issue, this issue is only about hooking up the events described and that they can be queried in re-dash)

Re-opening for QA to verify

Hi, I've just checked this on the latest Nightly Build #13230608 from 11/19 using a Google Pixel 3a XL (Android 9).

❓ Play/Pause from the open tabs section - Ping 5ef667d2-b9ec-47da-8239-d4876c925295

Aren't correctly generated (seem to be inverted, when pressing pause a "media_play" "tab" category ping is generated and vice versa) the correlation with the "media_state" category is done properly.

E.g.
1. Tap pause from the Open tabs
"events": [
{
"category": "tab",
"name": "media_play",
"timestamp": 0
},
{
"category": "media_state",
"name": "pause",
"timestamp": 135
}
]

2. Tap play from the Open tabs
"events": [
{
"category": "tab",
"name": "media_pause",
"timestamp": 0
},
{
"category": "media_state",
"name": "play",
"timestamp": 127
}
]

@vesta0 & @gabrielluong - Not sure if the Media usage from the Open tabs was also covered or should have been covered.
Please and let me know how should we proceed. ☺️

[AndiAJ]

I'll remove the QA needed label until further notice.

Hi @AndiAJ, only media_state pings were covered in this fixed. Seeing that tab.media_play and tab.media_pause are pinged incorrectly, can you open a new issue on that and we will look into that.

[AndiAJ]

Hi @gabrielluong , thanks for clarifying this! ☺️
I've re-tested this on Fenix Nightly Build #13391806 from 12/5 and it works properly.
