the cloud desktop client sends a cloud desktop login request to a virtual machine with an ICE (Internet communications and Internet Explorer) framework based on the detected first input operation;
after an ICE Display card switching module ICEDisplay in the virtual machine receives a cloud desktop login request, executing Display card switching operation, switching an operating system Display card Basic Display Driver to an ICE Display card Driver, and writing cloud desktop image information into a shared memory by the ICE Display card Driver;
the management terminal sends a cloud desktop screen recording request to the virtual machine with the ICE architecture on the basis of the detected second input operation of the system administrator;
after receiving a screen recording request, an ICE display card switching module ICEDisplay in a virtual machine calls an ICE image reading module ICESound in an ICE framework, sends a request for establishing a socket link to an ICE image transfer module ICERecord in a transfer server CSAP, obtains size information of an available storage space shared and stored on a host computer end after the ICE image transfer module ICERecord in the transfer server CSAP receives the request for establishing the socket link, judges whether the shared storage space of the host computer end is sufficient according to the size of a preset threshold value set by an enterprise management terminal, and completes the establishment of the socket link with the ICE image transfer module ICERecord in the transfer server CSAP if the shared storage space of the host computer end is sufficient through judgment.
The ICE image reading module ICESOUND records initial screen recording time information of the cloud desktop image information, simultaneously reads the cloud desktop image information from the shared memory, processes the information to obtain cloud desktop video stream information, uploads the obtained cloud desktop video stream information to an ICE image transfer module ICEREcordid in a transfer server CSAP, and the ICE image transfer module ICEREcordid in the transfer server CSAP further encodes the obtained cloud desktop video stream information and sends the encoded cloud desktop video stream information to a shared memory on a host.
When the appointed screen recording time length in the screen recording request sent by the enterprise management terminal reaches the longest screen recording time length, the ICE image reading module ICESound sends screen recording ending information to the ICE image transfer module ICERecord in the transfer server CSAP, and the socket link is disconnected with the ICE image transfer module ICERecord in the transfer server CSAP. And an ICE image transfer module ICEREcordid in the transfer server CSAP releases an encoder used for generating the screen recording information of the cloud desktop after receiving the screen recording ending information sent by the ICE image reading module ICESound. And an ICE image transfer module ICEREcordid in the transfer server CSAP sends screen recording ending information to the shared storage of the host end, stops transmitting video stream information to the shared storage, and disconnects network link with the host end to end screen recording.
