Problems solved by technology

For high-definition and high-bit-rate video files, the transcoding process is time-consuming
However, once the parameters are set incorrectly, the transcoded multimedia target file may not be able to be played on the mobile device. It is necessary to reset the transcoding parameters and re-transcode, which seriously wastes time and resources and is inefficient.

Embodiment approach 1

[0014] Such as figure 1 As shown, the multimedia transcoder provided in this embodiment includes: a pre-transcoding module 110, a parameter modification module 130, and a normal transcoding module 150; Initial transcoding parameters, the multimedia source file to be transcoded is pre-transcoded for a predetermined period of time to obtain the pre-transcoded file; the parameter modification module 130 is used to modify the pre-transcoded file when the playback of the pre-transcoded file is not normal. The above transcoding parameters, and the modified transcoding parameters are sent to the pre-transcoding module; the normal transcoding module 150 is used for when the playback of the pre-transcoding processing file is normal, according to the currently used pre-transcoding module The transcoding parameters are used to transcode the multimedia source file to be transcoded.

[0015] The multimedia source file is the multimedia file that the user wants to transcode, and can be any...

Embodiment approach 2

[0027] Such as figure 2 As shown, this embodiment provides a multimedia playback terminal 10, including a multimedia transcoder 100 and a player 200, wherein the multimedia transcoder 100 is the multimedia transcoder provided in Embodiment 1, and the player 200 is used to play multimedia The pre-transcoding processing file output by the pre-transcoding module of the transcoder or the transcoded multimedia source file output by the normal transcoding module. The player 200 is implemented using a common playback technology for those skilled in the art, which is not limited in this embodiment. Similarly, the multimedia player terminal in this embodiment can be, for example, DVD, CD, personal computer, mobile phone, MP4, MP3, PSP and so on.

Embodiment approach 3

[0029] This implementation mode provides a transcoding method for multimedia files, including the following steps:

[0030] In the pre-transcoding step S1, after the pre-transcoding mode is triggered, according to the initial transcoding parameters, the multimedia source file to be transcoded is pre-transcoded for a predetermined duration to obtain the pre-transcoded file;

[0031]Parameter modification step S2, when the pre-transcoding processing file is not played normally, modify the transcoding parameters, and return the modified transcoding parameters to the pre-transcoding step S1 to re-perform the pre-transcoding step S1;

[0032] In the normal transcoding step S3, when the pre-transcoding processing file is played normally, the multimedia source file to be transcoded is transcoded according to the transcoding parameters currently used in the pre-transcoding step S1.

[0033] pass below image 3 The illustrated embodiment describes in detail the processing flow of the ...

Abstract

The invention discloses a multimedia transcoder and a transcoding method. The transcoder comprises a pre-transcoding module, a parameter modifying module and a normal transcoding module, wherein the pre-transcoding module is used for carrying out pre-transcoding treatment of predetermined duration on a multimedia source file to be transcoded according to an initial transcoding parameter after a pre-transcoding mode is triggered so as to obtain a pre-transcoding treatment file, the parameter modifying module is used for modifying the initial transcoding parameter when the pre-transcoding treatment file can not be played normally and sending a modified transcoding parameter to the pre-transcoding module, and the normal transcoding module is used for transcoding the multimedia source file to be transcoded according to the transcoding parameter used by the pre-transcoding module currently when the pre-transcoding treatment file can be played normally. According to the multimedia transcoder, the transcoding method and a multimedia playing terminal, pre-transcoding of predetermined duration is carried out before complete transcoding of the multimedia source file, then trial playing is carried out, and therefore complete file transcoding is carried out only after a proper transcoding parameter is determined, the situation that transcoding needs to be carried out again after the completely transcoded multimedia source file is found unable to be played normally is avoided, and then time and resources are saved and transcoding efficiency is improved.

Description

technical field [0001] The invention relates to the field of multimedia processing, in particular to a multimedia transcoder, a multimedia file transcoding method, and a multimedia player terminal using the multimedia transcoder or the transcoding method. Background technique [0002] With the continuous evolution of the information industry, more and more mobile devices, such as iPad, iPhone, etc., have more delicate picture quality and higher hardware support. Therefore, it is no longer necessary to watch high-definition video on mobile devices. No matter how far away. However, because mobile devices are limited by memory, storage, CPU computing power, and power consumption, they are often powerless to play high-definition and high-bit-rate video files. This requires transcoding software to convert video files that cannot be directly played by these mobile devices into a format that can support playback. The transcoding process involves parameters such as file format, re...
