    摘要: A method and an apparatus for diagnosing memory leak. The method includes: tracing the allocation of objects; recording allocation paths and allocation time of each object; giving to each object one unique identifier (ID) corresponding to an allocation path; determining the allocation path to which each object belongs; organizing the objects which are allocated but still not collected, and counting the age generations of the objects of the similar type according to the allocation time of each object; ranking the allocation paths according to the age generations of the surviving objects; and analyzing the ranking of the allocation paths, in which the allocation path with higher rank is more probable to introduce memory leaks. Thus, the suspicious allocation path possibly incurring memory leaks is selected and reported to the user for analysis.

    摘要: Techniques are described related to performing random access starting from a random access point picture that is not an instantaneous decoder refresh picture. Some techniques are also related to reducing the amount of information that is signaled for long-term reference pictures of a reference picture set. Additional techniques are also related to decoded picture buffer management, such as removing decoded pictures based on a temporal identification value.

    摘要: Techniques are described related to output and removal of decoded pictures from a decoded picture buffer (DPB). The example techniques may remove a decoded picture from the DPB prior to coding a current picture. For instance, the example techniques may remove the decoded picture if that decoded picture is not identified in the reference picture set of the current picture.

    摘要: In one example, a video coder is configured to code a first slice, wherein the first slice comprises one of a texture slice and a corresponding depth slice, wherein the first slice has a slice header comprising complete syntax elements representative of characteristics of the first slice. The video coder is further configured to determine common syntax elements for a second slice from the slice header of the first slice. The video coder is also configured to code the second slice after coding the first slice at least partially based on the determined common syntax elements, wherein the second slice comprises one of the texture slice and the depth slice that is not the first slice, wherein the second slice has a slice header comprising syntax elements representative of characteristics of the second slice, excluding values for syntax elements that are common to the first slice.

    摘要: A video encoder is configured to determine a picture size for one or more pictures included in a video sequence. The picture size associated with the video sequence may be a multiple of an aligned coding unit size for the video sequence. In one example, the aligned coding unit size for the video sequence may comprise a minimum coding unit size where the minimum coding unit size is selected from a plurality of smallest coding unit sizes corresponding to different pictures in the video sequence. A video decoder is configured to obtain syntax elements to determine the picture size and the aligned coding unit size for the video sequence. The video decoder decodes the pictures included in the video sequence with the picture size, and stores the decoded pictures in a decoded picture buffer.

    摘要: The example techniques of this disclosure are directed to default construction techniques for the construction of a combined reference picture list, and default mapping techniques for the combined reference picture list. In some examples, a video coder may construct first and second reference picture lists from frame number values, and construct the combined reference picture list from the frame number values of the first and second reference picture lists. In some examples, a video coder may construct first and second reference picture lists from picture order count (POC) values, and construct the combined reference picture list from the POC values of the first and second reference picture lists. In some examples, a video coder may construct a combined reference picture list from received information for the construction, and map the pictures of the combined reference picture list to one of a first or second reference picture list.
