Media file transcoding system and method

Abstract

The invention discloses a media file transcoding system, which belongs to the technical field of multimedia. The media file transcoding system comprises a transcoding module, a user parameter setting module and a splitting module, wherein the transcoding module is used for converting the format of a source file; and the splitting module is connected with the transcoding module and the user parameter setting module and is used for processing an output data stream of the transcoding module according to a user parameter so as to obtain a plurality of media files. Moreover, the invention also provides a media file transcoding method. The splitting module is added to the conventional transcoding system and can convert a video file of one format into a plurality of video files of another format, so that a part of finished videos can be watched under the condition that transcoding is not fully completed; moreover, split small files are beneficial to playing in small-volume handheld equipment, so that great convenience is brought to users.

Description

【Technical field】 [0001] The invention relates to the field of multimedia technology, in particular to a transcoding system and a transcoding method for converting the format of a multimedia file. 【Background technique】 [0002] Multimedia (including video, audio, image, etc.) has become an indispensable and important part of people's work and study, and plays an increasingly important role in people's work, study and life. Multimedia has its applications in many fields. In response to people's different needs for multimedia services in daily work and life, some standardization organizations have proposed a variety of audio and video coding standards for different business needs in society. For example, the H.263 standard proposed for video telephony and video conferencing services; the Mpeg2 standard proposed for DVB, HDTV and DVD; the MPEG4 standard developed for streaming media services in the network; and the network-friendly H. 264 standard, etc. [0003] Due to the s...

AI Technical Summary

Problems solved by technology

For a home computer with an average CPU performance, the transcoding time is almost the same as the video playback time, so when transcoding a large video file, the waiting time for the transcoding to complete becomes unbearable

When the transcoding is not completed, the video file cannot be played

[0005] In addition, the size of the transcoded video file will generally not change significantly, and there will be problems if a large-capacity video file is placed in a handheld device with a small capacity such as a mobile phone or MP4.
