Other Parts Discussed in Thread: TMS320DM8147

Greetings,

I have an inquiry about H.264 codec engine of DM8147. I wonder if it is possible to turn on/off H.264 encoding modes in HDVICP. For instance,

- to choose between inter and intra-frame encoding

- to select one of intra-frame prediction modes

- to activate/deactivate rate constraint control

Thank you very much for your earliest response.

 

Best Regards,

Mohammad

    Look for the parameter lumaIntra4x4enable lumaIntra8x8enable  in the interface file or User Guide for more info.
