Hello,

I'm working on an H.264 encoding application on the MSM8974 platform (Nexus 5) and configuring parameters in OMX via the OMX_VIDEO_PARAM_AVCTYPE structure.

I've read the OMX_Video.h header descriptions, but I'm pretty sure the OMX component (hardware encoder) has constraints beyond what the header implies; for example nRefFrames in the H.264 standard (and in the header) suggests 1 thru 16, but it appears the encoder actually maxes out at 2.

I'd like to apprach this from a documentation perspective if such documentation is available to developers. 

Any leads appreciated!

Bjorn
