Embodiment
By describing technology contents of the present invention, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.
See also Figure 1A-B, show the flow chart of the video file code-transferring method of present embodiment.Figure 1A is the overall flow figure of code-transferring method, comprising:
Step 101 is written into video file and decodes.Video file can be any one file format commonly used in digital terminal equipment, AVI for example, MPEG, MPEG4,3GP, Windows Media Video, MKV and Real Media etc.Generate video/audio by the decoded video file.
Step 102 generates first tabulation that comprises at least one digital terminal type option.Referring to the tabulation of first among Fig. 2 201, comprised more than one digital terminal type option 203 in this tabulation, the various digital terminal types of the video file behind the transcoding are used in expression.The digital terminal type option can be at a certain digital terminal product, and for example on behalf of the video file of transcoding generation, the iPod option among Fig. 2 promptly will be used to use on the iPod media player that Apple produces.The digital terminal type option also can be at the digital terminal product of a certain type, for example the Mobile Phone option among Fig. 2.It is the digital terminal of which kind of type that the user obviously can know own employed, therefore is easy to select respective selection in first tabulation.
Step 103, certain the digital terminal type according to the user chooses in described first tabulation 201 correspondingly generates the tabulation of second among Fig. 2 202.Described second tabulation 202 has been enumerated one or more video file format options 204, each option representative in first tabulation 201 selected digital terminal type a kind of video format that can support.The user can as required or like and therefrom select a kind of video format.
Step 104 according to the video file format that the user chooses in described second tabulation 202, is a selected video file format in second tabulation 202 with decoded video file recompile.The user can be written into digital terminal with the video file behind the transcoding then, because the employing of the video file behind the transcoding is the supported video format of terminal, therefore can play use on terminal.
Figure 1B has made further detailed description to step 104:
In step 1041,, generate transcoding parameter options table in second tabulation 202 according to the video file format that the user is chosen.Fig. 3 shows the form of this transcoding parameter options table 301.In this pick list, " Format Preset " option shows the video file format of being chosen.Under the video file format of being chosen, it is various video code conversion parameters in the selected file format procedure that the user can adjust former video file transcoding in " Video " Option Box.Particularly, can " Resolution " resolution of video is set in the Option Box, the frame rate and the code check of video is set, by the encoder type of " Encoder " selcetion.removelistener recompile in " Frame Rate " and " Bit Rate " Option Box.Equally, can also in " Audio " Option Box, the transcoding parameter to audio frequency be provided with, utilize " Sample Rate ", " Channel ", " Bit Rate ", " Encoder " Option Box is provided with the encoder type of sample rate, sound channel, code check and the audio frequency recompile of audio frequency transcoding respectively.
Step 1042, the transcoding parameter of the Voice ﹠ Video of choosing in this transcoding parameter options table 301 according to the user to the audio, video data recompile of decoded video file, generates the video file of the file format of choosing.
Step 1043, the various transcoding parameters according to the user chooses in transcoding parameter options table 301 generate parameter configuration table, are used for the self-defining transcoding parameter of recording user.Store this allocation list,, need not to be provided with repeatedly the transcoding parameter so that directly call in the transcoding process afterwards.
The present invention also provides a kind of transcoding device of video file, as shown in Figure 4, comprising:
Decoder 401 is written into video file and decodes, and generates the video/audio for the treatment of transcoding;
Terminal type is selected module 402, generates first tabulation that comprises at least one digital terminal type option, as the tabulation of first among Fig. 2 201;
File format is selected module 403, and the digital terminal type according to the user chooses in described first tabulation 201 generates second tabulation 202, and described second tabulation 202 comprises at least one video file format option that this digital terminal type is supported;
The transcoding parameter is provided with module 404, according to the video file format of being chosen in second tabulation 202, generates transcoding parameter options table, as the transcoding parameter options table 301 among Fig. 3; The user chooses at the various transcoding parameters of looking audio frequency in this transcoding parameter options table 301.This module is used to control transcoder 405 according to the transcoding parameter of setting, 401 decodings obtain to decoder video and voice data recompile.The transcoder 405 video/audio recompile that obtains of will decoding is the video file format of choosing.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
