A video codec firmware management method and system

Abstract

The invention provides a video coding and decoding firmware management method and system. The method comprises the following steps of S1, obtaining a source file about multiple pieces of hardware; S2,processing the source file to generate a firmware package which is associated with a digital signature; S3, judging whether the digital signature corresponding to the firmware package is valid or not; if yes, carrying out data preloading on the firmware package to obtain firmware data corresponding to the hardware, and then executing the step S4; if not, abandoning the firmware package, and returning to the step S1; S4, filtering the firmware data to obtain available firmware data; and S5, driving the corresponding hardware according to the available firmware data, and then returning to the step S1. The method and the system have the beneficial effects that centralized management and flexible control are carried out on the scattered firmware data effectively, so that the use efficiency intime and space is improved; the reliability and confidentiality of the firmware data are enhanced; and simple operability of video coding and decoding firmware management is realized.

Description

technical field [0001] The invention relates to the field of video coding and decoding, in particular to a method and system for managing video coding and decoding firmware. Background technique [0002] With the advancement of science and technology, because high-quality video materials carry huge amounts of information, how to optimally process video information is becoming more and more important. At present, pure software is used for encoding and decoding, but the above technical solutions It is difficult to achieve an ideal effect, so the above-mentioned technical solutions can only be used as theoretical reference and guidance. [0003] Since the computing efficiency of the hardware codec function in the prior art is much higher than that of the software, it is currently a better technical solution to use hardware to process a large number of complex and time-consuming operations. Therefore, how to realize the high-efficiency operation of the drive hardware and the ea...

[0002] With the advancement of science and technology, because high-quality video materials carry huge amounts of information, how to optimally process video information is becoming more and more important. At present, pure software is used for encoding and decoding, but the above technical solutions It is difficult to achieve the ideal effect, so the above technical solutions can only be used as theoretical reference and guidance

[0003] Since the computing efficiency of the hardware codec function in the prior art is much higher than that of the software, it is currently a better technical solution to use hardware to process a large number of complex and time-consuming operations. Therefore, how to realize the high-efficiency operation of the drive hardware and the ease of use has become a new problem

[0004] At present, the method of video preloading cache firmware is used in the existing technology, and the firmware information is compiled into the kernel in the form of a static array. The above method of static integration can improve the efficiency of loading and use, but it will greatly increase the number of kernel images. The size of the file and the risk of data tampering, corruption and leakage
