Abstract: Embodiments of the present invention provide a method for video transcoding, an apparatus, an electronic device, a computer readable storage medium, and a computer program product.

Abstract: A system and method for virtualized video encoding and decoding, an electronic device and a non-transitory computer-readable storage medium are provided. The system includes a virtual machine manager, a virtual machine, a virtual machine register corresponding to the virtual machine, and a video encoding and decoding kernel. The virtual machine manager is configured to configure, into the virtual machine register, configuration information of a video encoding and decoding task corresponding to the virtual machine. The video encoding and decoding kernel is configured to read the configuration information from the virtual machine register, and execute the video encoding and decoding task according to the j-th video standard and on the basis of the configuration information.

Abstract: The present application provides a data caching method and a chip. The chip includes a plurality of video data sub-processors for caching different data types of video data respectively and a data prefetcher. The method includes: determining target video data according to identification information of a video data sub-processor of to-be-cached video data; determining a data storage address of the target video data in an external memory; and obtaining, by the data prefetcher, corresponding target video data from the external memory according to the data storage address. The present application may improve the data caching efficiency, reduce the data access, improve the computational efficiency of video data processing, and reduce the power consumption.
