It's arbitrary.
Frames may accumulate in the queue if the GStreamer pipeline is slow in
decoding them so setting this value too low may cause false positives.
So it should be large enough but not so large that the client takes ages
to realize something is wrong.
The server is currently sending a maximum of 30 fps (but the client does
not know that) so this is, at a minimum, a bit under 1 second worth of
frames queued up for decoding. That should really not happen.
Do you want that value in a macro? What name? How would you describe it?
