i.MX VPU h264 encode frame type

Question asked by du wu on Jul 7, 2016

I use VPU to encode  raw nv12(640x480) to h264.

After check the first 16 bytes of every encoded frame data, I find they are all "00 00 00 01 09 50 00 00 00 01 65  "(all I frames), But I have set the gopSize to 30.

 

The attachment is the output h264 which is static sceen, you can use VLC to play it.

 

My question is:

How to enable interframe compression?
