How do I configure the GOP structure with the TI codecs?
The GOP (Group Of Picture) structure defines the sequence of the I,P,B frames in the encoded video stream. For example IBBPBBPBBI could be a GOP structure. Depending on the profile supported an encoder may or may not support B frames. However I and P frames are always supported. The GOP structure is usually configurable using parameters to define the I-Frame period or to force a frame to by an I-Frame. For the DM644x H264 Base Profile Encoder, the intraFrameInterval and forceIFrame dynamic parameters are used for this purpose. Similar parameters are supported by all the video encoders from TI. Please review the specific user guides for more detailed information.
