HTML5: HTML5 is a language description way to build Web content. HTML5 is the next generation standard for the internet, a language way to build and present internet content. HTML was generated in 1990, 1997 and HTML4 became the internet standard and was widely used in the development of internet applications. HTML5 has been improved over the previous HTML 4.01. HTML5 brings the Web to a sophisticated application platform where video, audio, images, animation, and interactions with devices are regulated.
H.264: h.264 is a new generation digital video compression format following MPEG4 commonly proposed by the international organization for standardization (ISO) and the International Telecommunications Union (ITU). H.264 is one of video coding and decoding technical standards named by ITU-T in the H.26x series. H.264 is a digital video coding standard developed by the joint video team (JVT: joint video team) of VCEG (video coding experts group) of ITU-T and MPEG (moving Picture coding experts group) of ISO/IEC. The standard was originally derived from the development of a project called H.26L by ITU-T. The name h.26l, although less common, has been used. H.264 is one of the standards named by ITU-T under the name H.26x series, AVC being the name of the ISO/IEC MPEG side.
H.265 (HEVC): h.265 is a new Video Coding standard established after H.264 by ITU-T VCEG, the standard being known collectively as High Efficiency Video Coding (High Efficiency Video Coding). The h.265 standard encompasses the existing video coding standard h.264, retaining some of the original techniques, while improving some of the related techniques. The new technology uses advanced technology to improve the relationship between code stream, coding quality, time delay and algorithm complexity, so as to achieve the optimal setting. The specific research contents comprise: the method has the advantages of improving compression efficiency, robustness and error recovery capability, reducing real-time delay, reducing channel acquisition time and random access time delay, reducing complexity and the like.
HEVC: HEVC is an abbreviation for High Efficiency Video Coding, a new Video compression standard, used to replace the H.264/AVC Coding standard.
FFmpeg: FFmpeg is a set of open source computer programs that can be used to record, convert digital audio, video, and convert them into streams. LGPL or GPL licenses are used. It provides a complete solution for recording, converting and streaming audio and video. It contains a very advanced audio/video codec library libavcodec, in which many codes are developed from scratch in order to guarantee high portability and codec quality.
HLS: the HTTP Live Streaming (HTTP Live Streaming) is a Streaming media network transmission protocol based on HTTP, is a Streaming media solution, and can implement Live broadcast and on-demand broadcast of audio and video.
The H.265 standard improves some technologies on the basis of the H.264 standard, and can play videos with the same quality by only half of the original bandwidth, so that more bandwidth and capacity are saved on the basis of the same video quality. With the increase of network technologies and camera chip processing capabilities, security monitoring high-definition videos 720P and 1080P are gradually popularized, and the monitoring field and the beginning of 4K high-definition videos are in the beginning, so that standards such as MPEG-2, MPEG-4, h.264/AVC cannot meet the use requirements. Such as: the hard disk video recorder adopting the H.265 code can save half capacity compared with the H.264 code according to the video storage requirement of the same days.
On the basis, how to play the high-definition video in the h.265 coding format is a problem. At present, most hardware devices such as a display card of a notebook computer, a television device, and the like do not support hardware decoding of an h.265 video, so a playing device end generally adopts a software decoding mode to play. However, if the computer configuration is too poor or the code rate is too large, the system may be jammed and cannot smoothly play.
In this prior art solution, the h.265 coded video may be converted into the h.264 coded video in advance by the server side. However, this approach may double the server storage pressure and the technical advantage of h.265 coding to save more bandwidth and capacity is not realized. Secondly, in the existing scheme, a WebAssembly technology can be used to decode the h.265 coded video at the browser client, the method has high requirements on the decoding performance of the browser client, and requires a local machine to have strong single-core processing performance when the high-definition picture is decoded, and if the computer configuration is too poor or the code rate is too large, the video can be blocked and cannot be smoothly played.
The video playing method, the video playing device, the electronic device and the computer-readable storage medium provided in the embodiments of the present application aim to solve at least one of the above technical problems in the prior art.
The following describes the technical solution of the present application and how to solve the above technical problems in detail by specific embodiments.

In addition, because the server carries out coding format conversion respectively aiming at each file fragment, the storage resource of the server is less occupied, and the occupation of a large amount of server resources is avoided.
According to the method provided by the embodiment of the application, when an acquisition request of the target video file in the H.265 coding format sent by the terminal equipment is received, the file fragment of the target video file is acquired, and the identification information of the file fragment is returned to the terminal equipment, so that when the acquisition request of the converted file fragment sent by the terminal equipment based on the identification information is received, the converted file fragment in the H.264 coding format corresponding to the file fragment is acquired, and the converted file fragment is returned to the terminal equipment, so that the terminal equipment performs video playing based on the converted file fragment. In the scheme, because the file fragments of the target file are respectively converted, and the converted file fragments are returned to the terminal equipment for playing, video coding format conversion at the terminal equipment end is not needed, the terminal equipment can directly play the video based on the converted file fragments, the performance requirement on the terminal equipment is reduced, the playing jam is avoided, and the video playing effect can be ensured.
