Audio/Video delays in each room, ensure OK

[xfxf]

We have three different types of setups for the primary camera:

• Room 1 (keynote, with BM PCIe camera audio+video capture)
• Room 2,3,4,5 (BM USB audio+video capture)
• Room 6 (Opsis video capture,

Each of these may require a slightly different audio/video delay implemented somewhere in the vocto pipeline - all of these setups have been used for previous LCA's so clues about video or audio delay will be in a git repo.

This should be tested though. Do this like the following:

• Build a room setup, with a monitor acting as the projector
• Plug a laptop into the Opsis, to capture it.
• Point the camera at the monitor, so in Vocto all inputs are showing the same thing.
• Feed audio from the laptop into the camera.
• [1] Play a Youtube video with a speaking head (documentaries with interviews are good),

Verify that all inputs have proper lip sync. If any are out, then video/audio delays will need to be appropriately changed. It's best experimenting with this locally with values before committing to the ansible repo.

1 will be different to 2,3,4 & 5. Which will be different to 6.

[1] Alternatively, use some kind of A/V sync tool or video, such as Carl's clocky thing.

• Added delay for room a3 (camera though opsis).
• Peer added delay needed for other non-main rooms.
• Still need to work out delay for main room.
