Mathematically that would equal out to only using 2 threads, but I find a massive performance difference between running 2 threads and 3 threads - it would seem that the 2 less-demanding threads only use around 50% of a CPU core's available utilization even the video you're trying to play is running slower than real-time.
Strange, on the low grade 2c/4t processor, i get around 90% utilization, which means decoder must use at least 4 threads. Maybe You have any other bootlenecks
