The conventional method for avoiding this was to change the frame type of such a frame to an I frame, leaving the GOP structure basically unchanged. However

To exploit B-pyramid feature fully it's necessary to set GOP size (in frames) to a dyadic number (2^n), e.g. gop size = 16 frames or 32 frames. According to results of the above mentioned article “ANALYSIS OF HIERARCHICAL B PICTURES AND MCTF” using of Hierarchical B-Frames commonly improves coding efficiency (e.g. on Football CIF 30Hz, the improvement is about 0.5 Y-PSNR dB).

Here is the call graph for this function: void write_end_of_seq_rbsp. (. h264_stream_t *. h, You will get an intraframe compressed frame (the only one with all of the pixel and color data) then a pair of bi-directional predicted data (color predictions and luminance predictions) and then a predicted frame that is nothing more than a software prediction of where the colors are and where the detail has moved using the AME and there is nothing you can do to change that setting. I-frames are the key to the compression and following P and B-frames can use the data in I-frames to save on bits. However, what I would find interesting is knowing how the encoder determines which frames should be I-frames and which should be P's and B's and pull their data from them.

MF_MT_FRAME_SIZE: Frame dimensions. MF_MT_INTERLACE_MODE: Interlace mode. [!Note] In H.264 video, the interlace structure can change dynamically, so the recommended value of this attribute is MFVideoInterlace_MixedInterlaceOrProgressive.

The first image in a video sequence is always an I-frame. I-frames are Macroblock-adaptive frame-field (MBAFF) coding, using a macroblock pair structure for pictures coded as frames, allowing 16×16 macroblocks in field mode (compared with MPEG-2, where field mode processing in a picture that is coded as a frame results in the processing of 16×8 half-macroblocks).

Part 2: H.264 Bitstream format In previous topic I wrote about color models and how pixel color data can be stored. Now it is time to go deeper in H.264 bitstream format and find those pixels data. Obviously, the decoder operates with a sequence of bits received in a specific format.

After much searching I am yet to find another .NET implementation of encoding frames to H264 video, so I decided to write my own. The code below is based on the MediaFoundation C++ SinkWriter tutorial and implemented in .NET using the MediaFoundation.NET wrapper. The main changes I have made are:

A frame or field of video is decoded from an access unit (a series of NAL u its including one or more coded slices making up a coded picture). The decoding order
