Abstract
The invention discloses a real-time acquiring and uploading and data processing method and method for audio and video, and relates to the technical field of audio and video data uploading and processing. The method comprises the following steps: skipping to an audio and video file header as an audio and video film is recorded in a client and the stored coded header file is changed; obtaining the changed header file; sending to a server; replacing the previous header file for storing documents by the modified header file after the server receives the last modified header file with N bits; therefore, the file stored in the server can be completely recovered and can be played normally. With the adoption of the method and system, the audio and video can be uploaded on real time, and the file of the server can be directly played normally.
Description
Technical field
The present invention relates to audio, video data to upload and processing technology field, particularly relate to a kind of audio frequency and video Real-time Collection and upload and data processing method and system.
Background technology
Along with popularizing of the multiple mobile device such as smart mobile phone, vehicle mobile terminals, and the application of Sensor Network technology, using mobile terminal device to visit social networks becomes main flow gradually.In mobile Internet fast development process, 4G, 3G, Wi-Fi, WiMax are the collection of audio, video data, transmission and share and established physical basis.
User is after use smart mobile phone is made a video recording, to the video content produced, can pass through data connecting line (or the wireless connections such as bluetooth, WIFI) is transferred in computer (PC or notebook computer) hard disk, transcoding, compression is carried out again by the image software on computer, and then use special network upload software to upload to the Internet, so just, the video taken by mobile phone can be realized, to issue, the object shared on the Internet.
In prior art, the shooting of video and uploading, cannot accomplish instant issue, limit the intensity of user to the demand for services of mobile video Web realease.
And because client is when real-time recording shares audio frequency and video, the file header form of client write buffering area is the description to whole file, at the end of recording one section of audio frequency and video, the head form of client there occurs change, and the data now uploaded onto the server have read end of file, but the head form of file is still unaltered head form, it is temporarily impaired that the file of server is play, and cannot directly play.
Summary of the invention
The object of the embodiment of the present invention is that proposing a kind of audio frequency and video Real-time Collection uploads and data processing method, and being intended to solve the audio-video document uploading recording in real time and the file uploaded can the problem of normal play.
