Abstract

The invention provides an video and audio format conversion method, which comprises the following steps of: receiving first video and audio data, establishing a second video and audio file in a second video and audio format, acquiring first audio data and first video data from the first video and audio data, converting the first audio data and the first video data into the second video and audio format, and storing the first audio data and the first video data into the second video and audio file. In the video and audio format conversion method provided by the invention, after the first video and audio data is resolved to obtain the first video data and the first audio data, the first audio data is converted and stored as second audio data, the first video data is converted and stored as second video data, and the second audio data and the second video data are written into a media data box (mdat) in a 3GP video and audio format, so that various China mobile multimedia broadcasting (CMMB) programs can be appreciated by an electronic mobile device not supporting CMMB.

Description

technical field [0001] The invention relates to a conversion method, in particular to a video and audio format conversion method. Background technique [0002] At present, with the further improvement of China Mobile Multimedia Broadcasting (CMMB) network, mobile TV has also become a kind of entertainment in people's daily life. When enjoying a wonderful program, it is hoped that it can be saved and shared with relatives and friends at the first time through multimedia messages and other means. However, not every mobile phone supports the audio-visual format of CMMB, so it is very important to provide an audio-visual format conversion method to convert the audio-visual data of CMMB into a format supported by general mobile phones. Contents of the invention [0003] Therefore the purpose of the present invention is exactly to provide a kind of audio-visual format conversion method, to solve the problem that the multimedia audio-visual data of China Mobile Multimedia Broadc...
