Otherwise: increments by 1 from previous reference frame (in decoding order) (unless gaps_in_frame_num_value_allowed, in which case decoder has to create Typically, encoders use GOP structures that cause each I frame to be a "clean random access point," such that decoding can start cleanly on an I frame and any errors within the GOP structure are corrected after processing a correct I frame. In the newer designs found in H.264/MPEG-4 AVC and HEVC, encoders have much more flexibility about Attribute Description; MF_MT_FRAME_RATE: Frame rate. MF_MT_FRAME_SIZE: Frame dimensions. MF_MT_INTERLACE_MODE: Interlace mode.

The technique of H264 is used for this proj for compression. FSBM:in fsbm video is converted into frames(YCBCR or UVC format) and frames are compared

H264 frame structure

In the H264 format the byte stream is organised into many NAL unit. In order to understand where a NAL unit starts a three-byte or four-byte start code, 0x000001 or 0x00000001, is placed at the beginning of each NAL unit.

Macroblocks can be split into sub-blocks down to 4x4 pixels, see Figure 2. Macroblocks can be of the same types as the frame types enunciated in Section 3.1.

You can control number of reference frames (DPB buffer size) yourself by using NumRefFrame from mfxInfoMFX structure. To change number of reference frames in sample_encode.exe use [-x numRefs] option.
