  • Parallel preview stream and callback stream processing method and device
    Patent number: 11849213
    Abstract: Embodiments of this application provide a callback stream processing method and a device, and relate to the field of electronic technologies. In a callback stream scenario, an electronic device may set a preview stream and a callback stream in parallel. After an application sets a callback function, the electronic device may directly return, by using the callback function, callback stream data to the application for processing. This can shorten a time consumed for creating a preview stream and a callback stream, shorten a time consumed for obtaining callback stream data, and shorten a user waiting time.
