Abstract: Embodiments of the present disclosure provide a video bitstream encapsulation method and apparatus, a video bitstream decoding method and apparatus, and a video bitstream access method and apparatus. The video bitstream encapsulation method includes: encapsulating information of a Library Random Access Point (LRAP) sample in a first video bitstream into a media container file in which the first video bitstream is encapsulated; and encapsulating information of a library picture sample of the LRAP sample into the media container file, wherein the library picture sample is a reference picture sample of the LRAP sample. The solution may solve the problems in the related art that a video encoding manner using a library picture as a reference picture cannot allow for efficient accessing and processing of a video bitstream containing a reference picture sample and the processing is complex. The information of the LRAP sample is directly encapsulated into the media container file, so as to facilitate identification of the LRAP sample which can serve as a random access point and a library picture sample referred to by the LRAP sample, thereby reducing the processing complexity while satisfying the compression efficiency and avoiding waste of transmission bandwidth.
