Method of synchronisation #38

Open roaldarbol opened 1 year ago

Just want to check, as it doesn't specifically mention it in the docs: Is it the audio stream being used to synchronise the recordings? Currently I am recording with one camera that doesn't have audio, but I am still able to record videos - I guess that should throw an error if it is based on the audio stream?

It might be worth thinking about other ways, such as using cross-correlation of the lower-level features of the images themselves (e.g. changes in overall luminosity, contrast, etc.). There's a really good post about it on StackExchange. Especially for expanding to FLIR cameras (and Raspberry Pi cams, and many cheap USB cameras), it might be worth considering alternative methods.

Recently implemented in syncstart, maybe you can implement the same solution? https://github.com/rpuntaie/syncstart/pull/11
