Problems solved by technology

Encoding only for the specified test set is relatively one-sided and cannot fully reflect the encoding effect of real application scenarios, such as bit rate jitter, image quality consistency of scene switching, and long-term encoding stability
[0003] In the process of project development, the specialized testing department often uses some longer video files for verification. This approach can solve the above problems to a certain extent, but because these video files still have the problem of fixed content and scene switching points, it may cause encoding The case where the module encodes these specific files works well, but not for other untested files

Embodiment 1

[0027] refer to figure 1 , which shows the video encoding automation auxiliary system according to the embodiment of the present invention, including sequence storage library, compilation module, signal generation module, encoding module, recording module, encoding quality evaluation and analysis module and encoding sample library, wherein the sequence storage library uses For storing picture sequences, each picture sequence is a group of continuous pictures, and each sequence is composed of a sequence ID and a sequence picture set. Sequences include physical sequences (that is, original sequences) and virtual sequences, and virtual sequences (also called logical sequences) are partial pictures extracted from physical sequences and their combinations). The compilation module is used to combine several picture sequences into a longer sequence combination according to time order to form a program list. A picture sequence can be a physical sequence or a logical sequence. The co...

Embodiment 2

[0031] On the basis of the system embodiment 1, the video encoding automation assistance system of the embodiment of the present invention further includes a report and query module, which is used to check compilation and encoding files and evaluation indicators. Viewing methods are not limited to specific data or chart representations that combine data for further analysis (such as objective index fluctuation charts).

[0032] Furthermore, for the same encoded content sequence and encoding parameters, after encoding in different encoding library versions and format encodings, the quality score comparison can be performed.

[0033] Further, the system can also send a report to the corresponding user when all the tests are completed or during the test.

[0034] The above video coding automation auxiliary system can be deployed in a stand-alone mode or in a machine cluster mode. A stand-alone computer refers to an independent hardware computing platform, such as a single workst...

Abstract

The invention discloses an automatic auxiliary system and method for video coding, and the system is characterized in that a sequence storage library is used for storing a picture sequence, wherein the picture sequence comprises a physical sequence and a virtual sequence; a program editing module is used for combining a plurality of picture sequences into a longer sequence combination according to a time sequence to form a program list; a signal generation module is used for obtaining the program list from the list encoding module, analyzing the program list, obtaining a picture sequence, decoding the picture sequence into image bare data, and sending the image bare data according to a specified frame rate; a encoding module is used for receiving the image data of the signal generation module, and encoding the image data in a corresponding encoding format to form a code stream; a recording module is used for receiving the coded code stream and storing the code stream into a file; a coding quality evaluation and analysis module is used for carrying out coding quality evaluation by carrying out picture comparison on the coded target video and the source video before coding, and carrying out coding distortion quantitative analysis; and a coding sample library is used for storing coding files.

Description

technical field [0001] The invention belongs to the technical field of video encoding, and in particular relates to an automatic auxiliary system for video encoding. Background technique [0002] During the development process of major video coding projects, the test sets provided by the video coding standardization organization are often used to verify the coding objective indicators. Each content sequence in these test sets is a single scene and is short in duration. Encoding only for the specified test set is relatively one-sided and cannot fully reflect the encoding effect of real application scenarios, such as bit rate jitter, image quality consistency of scene switching, and long-term encoding stability. [0003] In the process of project development, the specialized testing department often uses some longer video files for verification. This approach can solve the above problems to a certain extent, but because these video files still have the problem of fixed conten...
