Hi all, I have some problems using the ffmpeg slice multithread h264 decoder tool.
These code lines 


open 16 threads but can't improve decoding performances. Only one thread is really working so performances are closed to no-multithread ffmpeg decoding.

How can I correctly use ffmpeg slice decoder tool?

Thx for your help
