The invention discloses a method and device for processing camera video data at a cloud terminal, and the method comprises the steps that the cloud terminal receives an instruction, transmitted by a virtual machine, of starting a camera for photographing, and starts the camera on the cloud terminal for photographing; raw photographing data is compressed and transmitted to the virtual machine for display after the cloud terminal determines that the camera has the raw photographing data through capturing. Therefore, the method and device can solve a problem that a high-resolution high-frame-rate camera cannot achieve a good display effect.
