Questions about some new stuff in the config

[spinningsand]

I only just recently installed the newest version and when I checked the config, I didn't know what some lines in it meant or if I should keep it the same or change them:

PortalUsername = 'olive'

PortalPassword = 'olive'

LogDir = '/Users/lucas/github/olive'

SaveDir = '/Users/lucas/github/olive/videos'

SplitRestSeconds = 60

CommanderPoolSize = 1

ParserMonitorRestSeconds = 10

CookieFilepath = '/Users/lucas/github/olive/cookies.json'

Threads = 6

MaxBytesPerSecond = 2097152

PostCmds = '[{"Path":"oliveshell","Args":["/bin/zsh","-c","echo $FILE_PATH"]},{"Path":"olivebiliup"},{"Path":"olivetrash"}]'

SplitRule = '{"FileSize":2000000000,"Duration":"1h"}'

I also noticed the parser was set to flv. Does that work better than ffmpeg (for TikTok specifically) or should I keep using ffmpeg?

EDIT: Sorry if this might be a lot of stuff to explain, but a brief idea is all I'd need.
