[Libav-user] Problem using ffmpeg slice multithread h264 decoder

[stefano deiala]

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

my_avcodec_context->thread_type=FF_THREAD_SLICE;
my_avcodec_context->thread_count=16;

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
