Provided are a video decoding method and apparatus for, in a video encoding and decoding procedure, when a merge candidate list of a current block is configured, determining whether the number of merge candidates included in the merge candidate list is greater than 1 and is smaller than a predetermined maximum merge candidate number, when the number of the merge candidates included in the merge candidate list is greater than 1 and is smaller than the predetermined maximum merge candidate number, determining an additional merge candidate by using a first merge candidate and a second merge candidate of the merge candidate list of the current block, configuring the merge candidate list by adding the determined additional merge candidate to the merge candidate list, and performing prediction on the current block, based on the merge candidate list.

Techniques and apparatuses are described for video frame codec architectures. A frame decompressor decompresses compressed frames to produce decompressed frames. A frame decompressor controller arbitrates shared access to the frame decompressor. Multiple cores of an SoC request to receive a decompressed frame from the frame decompressor via the frame decompressor controller. The frame decompressor controller can implement a request queue and can order the servicing of requests based on priority of the requests or requesting cores. The frame decompressor controller can also establish a time-sharing protocol for access by the multiple cores. In some implementations, a video decoder is logically integrated with the frame decompressor and stores portions of a decompressed frame in a video buffer, and a display controller retrieves the portions for display using a synchronization mechanism. In analogous manners, a frame compressor controller can arbitrate shared access to a frame compressor for the multiple cores.

Systems and methods are described herein for coordinating transcoders. Content may be received from different sources to be transcoded. Each transcoder of a plurality of transcoders may send data associated with content to each other to coordinate the plurality of transcoders. The data may indicate timing information for the encoded content and features of the content such as, for example, color, frame similarity, or frame type. The transcoders, while outputting encoded content, may coordinate either directly or via a broker. The transcoders may coordinate in order to synchronize their output so that frames, that may be received by each transcoder at different times, are aligned based on the timing information. The coordination and synchronization may improve error resilience. In the case of a transcoder/encoder or a site failure, there may be a seamless transition to a different transcoder/encoder and no reduction in performance because of the time alignment.

In various examples, a media stream may be received by a re-encode system that may leverage a recode engine to convert (e.g., at an interval, based on a request, etc.) an inter-frame associated with the media stream to an intra-frame. The intra-frame may be converted from the inter-frame using parameters or other information associated with and received with the media stream. The converted intra-frame may be merged into an updated segment of the media stream in place of the original inter-frame to enable storage of the updated segment—or a portion thereof—for later use.

A system to facilitate analyzing and/or processing video content using encoding logs is provided. The system includes a first analysis component, a second analysis component and a transcoding component. The first analysis component determines a first set of shot-change locations associated with a cut transition in a video sequence based on an encoding log associated with at least one previously encoded video frame. The second analysis component determines a second set of shot-change locations associated with a fading transition in the video sequence based on the encoding log associated with the at least one previously encoded video frame. The transcoding component processes the video sequence based on at least a portion of the first set of shot-change locations and the second set of shot-change locations.
