Abstract

The invention discloses a data package format method and system suitable for transmission. The method comprises: obtaining a multimedia file encoded in a first encoding format; demultiplexing the multimedia file, obtaining each frame of data encoded in the first encoding format, and displaying a time stamp; packaging code stream encoded in the first encoding format; decoding each frame of data encoded in the first encoding format to obtain YUV data; encoding the YUV data in a second encoding format to obtain each frame of data encoded in the second encoding format, and forming code stream encoded in the second encoding format via the multiple frames of data. By adopting the data package format method disclosed by the invention, the code stream retains all the information necessary for decoding and retains the time stamp for audio / video synchronization; the package format is simplified, so a decoding end is convenient to separate files; and the code stream is saved, and the header information is particularly simplified, thereby being more suitable for network transmission.

Description

technical field [0001] The present application relates to the field of data encapsulation formats, in particular, to a method and system for a data encapsulation format suitable for transmission. Background technique [0002] Multimedia data includes but not limited to audio data, video data, audio and video data, but in the current encapsulation technology, the data format after encapsulation is not simplified enough, the transcoding encapsulation format is read inconsistently, and the data redundancy after encapsulation is large, occupying bandwidth. [0003] The general encapsulation method is for decoding and playing. For example, mp4 and other encapsulation methods contain a lot of information such as decoding control parameters and playback positions. However, transcoded files only need frame data, time information, and decodable header information. [0004] Therefore, the present invention is proposed to simplify the encapsulation format to facilitate the transmissi...
