Embodiment 1

[0041] image 3 The implementation flow of the video recording processing method provided by Embodiment 1 of the present invention is shown, and the method includes steps S1 to S3, which will be described in detail below.

[0042] Step S1, the step of creating an AVI video recording receiving file: when the video recording starts, create an AVI video recording receiving file in the storage device.

[0043] It should be noted that, in this embodiment, a file is used to receive the data generated by the video recording. Therefore, when the video recording starts, an AVI recording receiving file is set up in the storage device to receive the AVI data stream generated according to the video recording. .

[0044] Step S2, the step of setting up the AVI data stream: set up the AVI data stream according to the video stream provided by the recording device in real time, and write the AVI data stream into the AVI video recording receiving file, wherein the video stream consists of con...

Embodiment 2

[0054] Figure 7 The video recording processing system provided by Embodiment 2 of the present invention is shown, which includes an AVI video recording reception file creation module 21 , an AVI data stream establishment module 22 and an AVI file generation module 23 . It will be described in detail below.

[0055] The AVI video recording receiving file creation module 21 is used to set up the AVI video recording receiving file in the storage device when the video recording starts;

[0056] Described AVI data stream establishes module 22, is used for setting up AVI data stream according to the video stream that video recording device provides in real time, and described AVI data stream is written into described AVI recording receiving file, wherein, described video stream is composed of continuous Streaming media packet is formed, and described AVI data stream is made up of file header, streaming media packet and the corresponding index packet with described streaming media ...

Embodiment 3

[0063] Such as Figure 9 As shown, in Embodiment 3 of the present invention, a video recording processing chip is provided, which includes at least one processor 310, memory 320 and interface 330, and the at least one processor 310, memory 320 and interface 330 are all connected through a bus;

[0064] The memory 320 stores computer-executable instructions;

[0065] The at least one processor 310 executes the computer-executable instructions stored in the memory 320, so that the video recording processing chip executes the video recording processing method described in Embodiment 1.

[0066] The embodiment of the present invention also provides a storage device, the storage device stores instructions, and when the instructions are executed by the processor, the steps of the video recording processing method described in the first embodiment are implemented.

[0067] In summary, compared with the need to establish two files for writing the AVI data stream into the storage devi...

Abstract

The invention provides a video record processing method, system and chip and a storage device. The video record processing method comprises an AVI record receiving file establishing step, namely, an AVI video receiving file is established in the storage device at the beginning of the video recording; an AVI data stream establishing step, namely, an AVI data stream is established according to a video stream provided by a video recording device in real time, and the AVI data stream is written into the AVI record receiving file, wherein the videos stream is composed of continuous streaming mediadata packets, and the AVI data stream is composed of a file header, streaming media data packets and an index packet corresponding to the streaming media data packets; and an AVI file generating step,namely, the streaming media data packets and the index packet in the AVI record receiving file are parsed out, and a file in the AVI format is generated. The cache occupation in the video recording process can be reduced by adopting the technical scheme of the invention.

Description

technical field [0001] The invention belongs to the technical field of video storage, and in particular relates to a video recording processing method, system, chip and storage device. Background technique [0002] With the development of science and technology, various camera devices are widely used, such as surveillance cameras for security and driving recorders, etc., and these devices usually continuously record and store video. Usually, the captured video image is compressed to obtain JPG image data and PCM audio data, and then the corresponding INDEX (index) data is constructed according to the JPG image data and PCM audio data, and the AVI data stream can be constructed. [0003] Such as figure 1 As shown, the AVI file stream includes JPG stream, PCM stream, and IDEX stream. The format of the traditional AVI data stream is: HEADER (header) block + {JPG (image) block + PCM (audio) block} x N (pieces) + INDEX (index) blocks. Usually, when a video recording file is co...
