As I said, there is no good static value. This value is used only in case of
heavy error (like a deadlocked decoder or sout) and is never used otherwise.
But the previous value was harmful for some streams (like raw HD video) or
for big pts_delay with high bitrate.
The value could be tuned with OPTIMIZED_MEMORY but well it means all and
nothing...
