Behavioral Video Sync

WIP: 2019-12-31

Update (2019-12-31): This is mainly in a working state; however, automated parsing of VidStreams and ledAlign UI were temporarily put on hold as I wanted to prioritize some of the other things before FB left (MM)

Methods

The video synchronization process should only involve three main methods associated with any Block object, as listed below (for the time-being). Later, we may want to add more methods here to allow extraction of "pixel time-series" similar to the SVD algorithm implemented in this Nature Neuroscience article (from journal club).

doVidInfoExtraction

Get video metadata for associated behavioral videos.

doVidSyncExtraction

Get time-series for sync event cross-correlation (?)

So, for example, the idea is that there is a sync signal such as an LED or an audio cue.
Use that signal with some signal in the digital record to synchronize the video and ephys recordings.
