May 28, 2020 The decoder does not depend on or require any other frames in order to create the image. In H.264 and beyond, a special type of frame called an

An H.264 stream contains a sequence of frames. The display order does not necessarily correspond to the encode order, i.e. the order the In the actual H264 data frame, the frame NAL type is often preceded by a 00 00 00 01 or 00 00 01 delimiter. Generally, the first frame data compiled by the In general, there are two ways to package the H264 stream. One is the format of the annex-b byte stream format. This is the default output format of most encoders , SP and SI frames are new picture types introduced in the latest video coding standard H.264.

This attribute applies to media types for H.264 streams transmitted over USB. For H264: Remove RTP header. If chunk NAL type (in first byte) is SPS (7) or PPS (8) mark the frame as IFrame (many cameras not use SPS and PPS (Axis included)). If chunk NAL type is #28 FU A (fragmentation unit A), check FU Header (next byte) if is NAL type IDR (5) (IDR (Instantaneous Decoding Refresh) Picture) is an IFrame. Examples: If a prefix appears in the body of the H264, it is changed from 00 00 00 01/00 00 01 to 00 03 00 00 01/00 03 00 01. We see commonly used naltype like sps= 0x07 pps= 0x08 sei = 0x06 i/p/b= 0x01/0x05 that is to say only Naltype = 0x01/0x05 is not judged out i/p/b frame type, need to go to the slice layer to determine the use of "Entropy Code" specific "Entropy coding" content, please see: "H 2010-11-29 2013-07-31 Referenced frames are frames that refer to other frames (eg. if both frames are similar).

Consists of B-macroblocks (each macroblock is predicted using one or two reference frames) and / or I-macroblocks. 2 I-slice. The H.264 format actually supports two different types of I-frames – traditional keyframe "IDR" I-frames which represent suitable restart points (IDR stands for "instantaneous decoder refresh"), and other, lesser, non-IDR I-frames in which frames after the non-IDR I-frame can still refer to frames before the I-frame, meaning the non-IDR I-frame can't be used as a restart point, but it's 2008-07-24 0 means current frame is identical to previous frame, and 100 means it is completely different. keyint is the maximum permitted distance between two keyframes; minkeyint is the minimum. IDR (instantaneous decoder refresh) frames are keyframes such that no future frame requires to refer to a frame earlier than the IDR-frame for decoding.

To set this attribute, call IMFAttributes::SetUINT32.

This determines the maximum distance between I-frames. Very high GOP lengths will result in slightly more efficient compression, but will make seeking in the video somewhat more difficult.

If chunk NAL type (in first byte) is SPS (7) or PPS (8) mark the frame as IFrame (many cameras not use SPS and PPS (Axis included)).

Referenced frames are frames that refer to other frames (eg. if both frames are similar). Having a high referenced frame will improve quality but slow up encoding. For typical content, a reference frame of 3 to 5 is recommended. For content with a lot of repetition (eg. animation), a reference frame …
