Description
Technical Field
The invention relates to the technical field of video and audio processing, in particular to a method for supporting video and audio file content addition based on object storage.
Background
Along with the vigorous development of the Chinese broadcast and television industry, the program making requirements are higher and higher, the timeliness and the high efficiency of media contents need to be considered, if the program contents can not be edited at the same time of acquisition, the timeliness of content transmission can be reduced, the time for making the program is wasted, but the current mode for storing the used objects can not meet the requirements of acquisition and editing at the same time, and the following defects exist:
1. the file is invisible to the user during writing
When the object is used for storage at present, the file is invisible to a user in the writing process, and the user cannot perceive the writing progress of the file, so that long-time waiting can be caused, the timeliness of content transmission is reduced, and unnecessary time waste is caused;
2. file can not be edited in writing process
At present, when an object is used for storage, a user can only read a complete file, if the file is always written in the process, the user cannot read the file, and the video file in the acquisition process cannot form the complete file in the storage because the content is always additionally written in the video file in the acquisition process, so that the user cannot edit the file in the acquisition process, and the file editing efficiency is greatly reduced.
Disclosure of Invention
The invention aims to: in order to solve the problems that the existing file adopting an object storage mode cannot be edited in the writing process and has low timeliness and efficiency, the invention provides a method for supporting the content addition of a video-audio file based on object storage.
The invention specifically adopts the following technical scheme for realizing the purpose:
a method for supporting content addition of video and audio files based on object storage comprises the following steps:
s1: writing a source file, and generating a corresponding inx file according to a source file format, wherein the inx file records the offset and the size of each frame of a video and audio file of the source file;
s2: writing the video and audio files and the inx file into the object storage in an additional writing mode;
s3: when the writing of the video and audio files is finished, deleting the corresponding inx files;
s4: when the video and audio files are read, whether the corresponding inx file exists in the video and audio files is judged, if the corresponding inx file does not exist, the video and audio files are completely written into the object for storage, and the video and audio files are directly read; if the corresponding inx file exists, the video and audio file is read according to the offset and the size of each frame of the video and audio file recorded by the inx file.
Further, the inx file comprises a head part and a data part, wherein the head part is used for storing medada data of the source file, and the medada data is used for describing the video and audio coding format, the video and audio stream number and the duration information of the source file; the data part is used for storing the index data of each frame of the video and audio file in the source file, and the index data records the offset position of each frame of video and audio in the source file, so that the frame to be taken can be conveniently found when the file is read.
Further, the additional writing in S2 includes the steps of:
s2.1: receiving a http write request of a source file, checking whether an object in object storage exists, and if the object does not exist, returning a request failure; if the object exists, reading the manifest data of the object;
s2.2: checking whether the position of the written content is the last fragment described by the manifest data; if so, writing new data in the tail of the fragment, and updating manifest data to describe the size of the fragment; if not, a new fragment is created, new data is written in the new fragment, and new fragment information is added in the manifest;
s2.3: if the new data can not be written in the S2.2, adding a new fragment, writing the new data which is not written in the new fragment, and adding the description information of the new fragment in the manifest until the new data is completely written in;
s2.4: and after the new data is completely written, forming a target file, and returning an http writing request result.
Further, when the corresponding inx file exists in S4, reading the video and audio files includes the following steps:
s4.1: after receiving a target file http read request, checking whether an object in object storage exists, and if the object does not exist, returning a request failure; if the object exists, reading the manifest data of the object;
s4.2: calculating the fragment position and the fragment offset of the tail of the target file, and reading data;
s4.3: and returning the http read request result.
The invention has the following beneficial effects:
1. in the method, in the process of writing a source file into an object storage, the object storage is written in a data appending mode, so that the file is visible to a user in the acquisition process, and the user can read the file and edit the file in the acquisition process, thereby realizing the method for supporting the acquisition and editing of the video and audio files in the object storage; and the S3 protocol is modified by combining with the analysis of the video and audio file format, so that the video and audio file can be packaged into a complete file in the writing process, and a user can read and edit the file in the acquisition process, thereby greatly improving the program making efficiency and having the characteristics of high efficiency, practicability, convenience in maintenance and cost reduction.
