Abstract:
A multimedia encoding/decoding method and device for a multi-operating system, and an electronic device. The method comprises: in a client operating system, receiving a multimedia processing request sent by an adaption layer and sending the multimedia processing request to a host operating system, the multimedia processing request comprising a multimedia file (201); and in an OpenMAX integration layer (IL) of the host operating system, loading and controlling a hardware codec in the host operating system to encode/decode the multimedia file (202). The described method can enable a client operating system to use a hardware codec in the host operating system in a cross-system manner so as to achieve the purpose of hardware acceleration.
