Problems solved by technology

[0003] However, since the multi-stream output of the hardware chip is limited by the performance of the hardware, the above-mentioned common chip can only output one H.264 compressed video at most. If the hardware multi-stream is used, the resolution and frame rate must be reduced, and the hardware cannot be fully utilized. characteristics, resulting in waste of resources

Embodiment Construction

[0011] The technical solutions of the present invention will be further described in more detail below in conjunction with specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0012] Now more and more people regard watching videos as entertainment in their spare time. With the development of video technology, they can watch the same video content anytime and anywhere through computers, TVs and mobile terminals. However, in order to match the code stream of the same video content to different playback terminals, it is necessary to generate a video file with a corresponding code rate, which requires high performance and high cost for transcoding hardware devices. The existing HiSilicon ...

Abstract

The present invention discloses a video code stream output control apparatus and method. The apparatus comprises a copying module, a grouping module, a processing module and an outputting module. The copying module is used for receiving an input video file, and copying the video file to generate at least two same video files. The grouping module is used for grouping each video file according to a transmission sequence, wherein each group comprises equal quantity of frame data. The processing module is used for keeping one of the video files unchanged, and deleting any at least one frame data of each of the other video files according to different preset rules, wherein after deletion, quantities of frame data of all other video files are different, after each group of frame data is deleted in the same video file, the quantities are the same, and positions of the deleted frame data are the same. The outputting module is used for receiving each video file, and outputting the video files to a play device according to the transmission sequence. According to the method and apparatus, the hardware characteristic of a chip can be taken into full advantages, multiple paths of code streams of different code rates and different FPS is output, and the performance of original hardware code stream is not damaged.

Description

technical field [0001] The present invention relates to the field of video technology, in particular to a video code stream output control device and method. Background technique [0002] At present, the video processing chips in ordinary civilian cameras, such as the HiSilicon 3518 chip (Hi3518), integrate a new generation of ISP, an optimized pre-encoding image processing algorithm and a new generation of H.264 encoder. At the same time, it adopts advanced low-power technology and internal low-power architecture design, which has the characteristics of low bit rate, high image quality and low power consumption. [0003] However, since the multi-stream output of the hardware chip is limited by the performance of the hardware, the above-mentioned common chip can only output one H.264 compressed video at most. If the hardware multi-stream is used, the resolution and frame rate must be reduced, and the hardware cannot be fully utilized. characteristics, resulting in waste of ...
