[x264-devel] B hierarchical

[Esther Madejón López]

Dear experts,

I would like to know if  B hierarchical in x264 are compatible with the 
use of several threads.

I am trying to encode a X264 stream using:

-B 500 -I 5 -b 3 --no-b-adapt --b-pyramid --threads 2 --ref 1

The problem is that x264 transforms B frames in P frames (IPBPBI...)

However, it works correctly (IPBrefBBI...) using the following parameters:

-B 500 -I 5 -b 3 --no-b-adapt --b-pyramid --threads 1 --ref 1

I would be grateful for any help.

Best regards

Esther
