DM6467: H264enc vbv size

Marc LEFORESTIER

Hi,

I am currently developping a compression card on DM6467 with TI H.264 codecs. I use Gstreamer to "connect" input video with the codec part.

I saw that h264fhdvenc propose a way to set the VBV size with the value maxDelay in DynamicParams, but I can't find it for h264enc. In the documentation, I can't find any information on this buffer, if it exists and what is its size. Does anyone know this information? And if it exists, how can I resize this buffer in order to have a smaller latency?

My codecs are from the cs2dm6467_1_00_00_10 package and their clients are compiled and integrated in arago 2011.6 with Code Sourcery 2009 Q1.

Thank you in advance.

Hi Marc,

This feature has not been supported in h264enc code base.

Hi,

Thank you for your answer.

I'm aware that this feature is not supported as said in the documentation. But does the h264enc codec have a default vbv buffer ? does it have a "zero latency" type mode?

Thank you.

Hi Marc,

H264enc has a vbv buffer, but the feature has not been added where the user can confgure it. Yes, it has a zero latency.
