Monitoring - Ingest video data, especially sound #94

Closed RichiH closed 7 years ago

RichiH commented 8 years ago

We should have "normal" paramaters of loudness, sync, left/right, etc and ideally expose those to the monitoring. We have many videos for 2016 with low volume, some with no sound, many too dark, etc pp.

At least part of those should be caught via instrumentation and alerts.

I was also thinking about a SPL Metric of some kind, which would allow detection of disconnected mics.

RichiH commented 8 years ago

Aye, that's what I meant with "no sound", but the underlying technical answer may be more complex than I think.

Listening in on streams is still good, and needed, but we should detect stuff if people don't listen in for whatever reason.

Colour distribution for "shadows against wall that's being recorded by mistake"

Thulinma commented 8 years ago

We should be able to provide audio levels for L/R in some shape or form, at least. Also - bitrate is a good indicator for movement/audio. And we can definitely provide the current bitrate of each stream.

RichiH commented 8 years ago

EBU R128 seem to be the specs we want for sound monitoring.

Thulinma commented 8 years ago

https://ffmpeg.org/ffmpeg-filters.html#astats <-- This might also be useful. Especially since we can relatively easily extract it.

Working, we have data in prometheus and a grafana dashboard.
