Ability to test with portrait videos in lk egress test-template

[srsudar]

The lk egress test-template tool is great.

One difficulty is that I am not able to see what it looks like to stream portrait videos--the default videos (the sun, the cloud, and the Tron-like valley) are all landscape streams.

Is there a way to customize the videos being used in these templates? I'm trying to make it easier to test what it looks like when someone is streaming from their phone, not just a desktop.

I'm running a command like this:

lk egress test-template --base-url http://localhost:3001 --room test \
  --layout desktop-grid --publishers 2

Any tips would be much appreciated!
