OBS filters can only add a short delay.
Add delay- how long? (delay is memory- or disk-intensive*) OBS can insert a
short delay, but longer ones usually mean writing data into a file and
playing it back later (which could be only 5 seconds). There are many
"gotchas" around that with file format and record/play timing. Please start
a separate email thread for that.
*(back-of-the-envelope calculation) if you assume uncompressed 8-bit RGB HD,
that's over 6MB/frame, a 30 second buffer at 30fps will need to be something
like 6GB (spinning disks aren't fast enough for this, needs to be SSD or
Add "chat"- that's not a function of the stream.
Add "alerts"- what does that mean in this case?
