Nettet23. jul. 2024 · In H.264 only a small fraction of the frames in a video data stream are so-called I frames, also known as key frames or Instantaneous Decoder Refresh (IDR) frames. The rest are P (predictive) frames or B (interpolated) frames. In other words each decoded frame depends on the previous one.

Similar to I-frames in that they contain all of the information a decoder uses to decode the frame, but frames cannot reference any … NettetSome codecs also define a special I-frame type called an IDR-frame (instantaneous decoder refresh frame) that, in addition to being intra-coded, also clears the contents of the DPB. That means all subsequent frames/pictures/slices are guaranteed to not refer to any frame decoded prior to the IDR-frame.

NettetFor adaptive live streams, all fragments should be self-initializing, meaning they start with a Program Map Table (PMT)/Program Association Tab (PAT) definitions and a full H.264 Instantaneous Decoder Refresh (IDR) frame.

NettetThis approach enables resolution changes within a video sequence at any frame without the insertion of an instantaneous decoder refresh (IDR) or intra random access picture (IRAP). The underlying techniques include reference picture resampling and handling of interactions between the existing coding tools and the changes in resolution. 3 Definitions 3.62 instantaneous decoding refresh (IDR) picture: A coded picture in which all slices are I or SI slices that causes the decoding process to mark all reference pictures as "unused for reference" immediately after decoding the IDR picture.
