Problems solved by technology

[0002] H.265 is a new video coding standard formulated by ITU-T VCEG after H.264. Compared with the previous H.264 standard, it has been greatly improved. It only needs half of the original bandwidth to play the same quality video. For video, the H.265 standard also supports 4K (4096×2160) and 8K (8192×4320) ultra-high-definition video. In view of the huge advantages of H.265 over H.264, the demand for video data transmission based on H.265 It is getting bigger and bigger, and various platforms such as Android support H.265. But until now, as the cornerstone of the B / S architecture-browser, none of them support H.265

Embodiment Construction

[0032] This embodiment is a preferred implementation mode of the present invention, and other principles and basic structures that are the same or similar to this embodiment are within the protection scope of the present invention.

[0033] Refer to the flow of the embodiment of the cross-browser H.265 video playback method of the present invention figure 1 As shown, the audio and video data flow of the playback method refers to figure 2 shown. The cross-browser H.265 video playing method of the present embodiment comprises the following steps:

[0034] S1, compile the source code of the H.265 video decoder into a WebAssembly library to generate a .wasm file;

[0035] S2, the browser establishes a network connection with the server, and loads the .wasm file;

[0036] S3, the browser's WebAssembly module compiles the .wasm file to obtain the WebAssembly library;

[0037] S4, the classes and methods of the H.265 video decoder are exposed to the JavaScript engine of the brow...

Abstract

The invention discloses a cross-browser H.265 video playing method and a cross-browser H.265 video playing device. A decoder of an H.265 video is compiled into a. Wasm format which can be called by aJavaScript engine of a browser after instantiation by using a WebAssembly technology, so that the browser can directly play the H.265 video on a webpage without additionally installing a client and the like; since the browser can play the video file based on H.265, the server can directly store the video file encoded by H.265, and the storage space of the server can be greatly saved.

Description

technical field [0001] The invention relates to the technical field of video coding, in particular to a cross-browser H.265 video playing method. Background technique [0002] H.265 is a new video coding standard formulated by ITU-T VCEG after H.264. Compared with the previous H.264 standard, it has been greatly improved. It only needs half of the original bandwidth to play the same quality video. For video, the H.265 standard also supports 4K (4096×2160) and 8K (8192×4320) ultra-high-definition video. In view of the huge advantages of H.265 over H.264, the demand for video data transmission based on H.265 It is getting bigger and bigger, and many platforms such as Android support H.265. But until now, as the cornerstone of the B / S architecture-the browser, none of them have supported H.265. How to directly play H.265 standard video on the browser has become a technical problem to be solved urgently in the industry. Contents of the invention [0003] Aiming at the proble...
