Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] Such as figure 1 As shown, the seamless file collection method provided by the present invention includes the following steps:

[0028] Step S01, setting a data buffer pool at the front end of the encoder, and storing video and audio data in the buffer pool in chronological order;

[0029] Step S02, opening the exit of the data buffer pool, starting the data reading thread, so that the unencoded video and audio data is synchronously output through the buffer pool, and enters the encoder for file encoding;

[0030] Step S03, when the output file needs to be switched, the system sends a file switching message;

[0031] Step S04, synchronize the video and audio data in the buffer pool again, so that the total length of the video stream sent to the encoder is equal to the total length of the audio stream, then close the exit of the data buffer po...

Abstract

The invention relates to a video and audio file collection technology, in particular to a seamless collection method and system aiming to video and audio files. The method comprises the following steps that a data cache pool is arranged at the front end of an encoder, video and audio data are stored into the cache pool according to a time sequence; the outlet of the data cache pool is opened so that uncoded video and audio data are synchronously output through the cache pool and enter the encoder to encode a file; when an output file is switched, the system sends a file switching message; the video and audio data are synchronized in the cache pool again so that the total length of a video stream sent to the encoder is equal to the total length of an audio stream sent to the encoder, and then the outlet of the data cache pool is closed; the encoder enables encoded data in the encoder to generate a file and outputs the file to a target position of a hard disk; the outlet of the data cache pool is opened again, and encoding operation is repeated until all the video and audio data are collected. The invention can not lose data during encoding, thereby ensuring the integrity of video and audio file collection.

Description

technical field [0001] The invention relates to video and audio file collection technology, in particular to a seamless collection method and system for video and audio files. Background technique [0002] The video and audio file acquisition system is widely used in radio and television program recording, video website content production, security video monitoring and other fields. The main function of the system is to encode video and audio signals into files and save them. Since the storage capacity of video and audio files is generally relatively large, the process of writing data to such a large file takes a long time, and if the computer system is disturbed by instantaneous unstable factors during this process, data writing will occur. A brief pause in the process and loss of data. Therefore, in the process of saving video and audio files, in order to avoid a single file from being too large, video and audio data are often divided into multiple pieces of data in chro...
