Methods and devices for image loading and methods and devices for video playback

A method for image loading, wherein the method comprises:

• pre-storing, by a server, a compressed texture list of a webpage, the compressed texture list of the webpage comprising an identification of the webpage, an identification of one or more basic images, which are used by a Canvas on the webpage, and an address identification of compressed texture data corresponding to the one or more basic images;
• receiving, by the server, the identification of the webpage and a compression format supported by a Graphic Processing Unit (GPU) sent by a browser;
• sending, by the server, to the browser the compressed texture list of the webpage;
• receiving, by the server, a request message requesting compressed texture data corresponding to a basic image sent by the browser, the request message comprising an address identification of the compressed texture data corresponding to the basic image if the address identification is obtained by the browser from the compressed texture list, and an identification of the basic image and the compression format supported by the GPU if the address identification of the compressed texture data corresponding to the basic image is not obtained by the browser from the compressed texture list;
• obtaining, by the server, compression format data that contains the compressed texture data according to the request message;
• and
• sending, by the server, to the browser the compression format data that contains the compressed texture data, to cause the browser to send the compressed texture data to the GPU, to cause the GPU to send the compressed texture data to the Canvas for drawing.

A device for image loading, the device comprising:

• a generation unit comprising:
• a parsing sub-unit that determines whether an image in a target webpage comprises a preset attribute for identifying the image as the basic image;
• an identification sub-unit that, when the first parsing sub-unit parses that the image in the target webpage comprises the preset attribute, identifies the image as the basic image, and obtains the identification of the basic image;
• a generation sub-unit that generates a request message requesting compressed texture data corresponding to the basic image, the request message comprising an address identification of the compressed texture data if the address identification is obtained by a browser, and the identification of the basic image and a target compression format supported by a Graphic Processing Unit (GPU) if the address identification is not obtained by the browser;
• a first sending unit that sends the request message generated by the generation unit to a server;
• a receiving unit that receives compression format data that contains the compressed texture data corresponding to the basic image sent by the server according to the request message;
• and
• a second sending unit that sends to the GPU the compressed texture data contained in the compression format data, to cause the GPU to send the compressed texture data to a Canvas for drawing.

A device for image loading, the device comprising:

• a pre-storing unit that pre-stores a compressed texture list of a webpage, the compressed texture list of the webpage comprising an identification of the webpage, the identification of one or more basic images, which are used by a Canvas on the webpage, and the address identification of compressed texture data corresponding to the one or more basic images;
• a first receiving unit that receives the identification of the webpage and a compression format supported by a Graphic Processing Unit (GPU) sent by a browser;
• a first sending unit that sends to the browser the compressed texture list;
• a second receiving unit that receives a request message requesting compressed texture data corresponding to a basic image sent by the browser, the request message comprising an address identification of the compressed texture data corresponding to the basic image if the address identification is obtained by the browser from the compressed texture list, and an identification of the basic image and the compression format supported by the GPU if the address identification of the compressed texture data corresponding to the basic image is not obtained by the browser from the compressed texture list;
• an obtaining unit that obtains compression format data that contains the compressed texture data according to the request message received by the first receiving unit;
• and
• a second sending unit that sends to the browser the compression format data that contains the compressed texture data obtained by the obtaining unit, to cause the browser to send the compressed texture data to the GPU, to cause the GPU to send the compressed texture data to the Canvas for drawing.
