Multi-threaded encoding while mixing multiple stream recordings

Multiple stream recordings are mixed a twice faster when multithreaded multi-threaded encoding is enabled comparing to singe-threaded one.

{

If mixing takes a long time, threads count may be increased, but it is not recommended to set it more than CPUs count, which can be detected by the following command

lscpu | grep -E "^CPU\(s\)"
