Problems solved by technology

Although there are some video file format conversion software in the prior art, there is no video format conversion method that can obtain the best video effect, especially the user cannot know how to select the encoding format and packaging format and the best video format when performing video conversion. Optimal encapsulation parameters, resulting in the problem that sometimes the converted video effect is poor or even unplayable

Embodiment 1

[0058] In this embodiment, the video transcoding method is further optimized when the requester currently requesting video file format conversion does not select several sets of preset H.263 encoding parameter values, which will be described in detail below.

[0059] figure 2 Shown is a flow chart of a video file format conversion method provided by Embodiment 1 of the present invention, as figure 2 As shown in , the method includes:

[0060] Step S201: Decapsulate and decode the video file to be converted to obtain source data; as mentioned above, before this step is executed, several sets of parameter values ​​of H.263 encoding need to be preset.

[0061] Step S202: Perform frame rate conversion on the source data to obtain converted source data.

[0062] Step S203: According to the video file format conversion request of the requesting end, several sets of preset H.263 encoding parameter values ​​are provided to the requesting end.

[0063] Step S204: Determine whether...

Abstract

The invention discloses a video file format converting method and device to achieve the purpose that a user can convert video formats conveniently and realize the optimal video quality. The video file format converting method comprises steps as follows: unpacking and decoding a to-be-converted video file to acquire source data; performing frame rate conversion on the source data to acquire converted source data; performing H.263 coding on the converted source data to acquire H.263 coded data; performing 3GP packing on the H.263 coded data to obtain a video file with the output format of 3GP, wherein the compatibility adopts the std item. According to the method, H.263 coding and 3GP packing methods are bound together to be implemented, the user is not required to select matching of coding and packing methods, the compatibility adopts the std item, the application range of the video file with the format converted is enlarged, and the effect of the video file with the format converted is improved.

Description

technical field [0001] The invention relates to the field of video technology, in particular to a video file format conversion method and device. Background technique [0002] With the development of multimedia technology, in order to meet the needs of video storage, people have set different video file formats to put video and audio in one file to facilitate simultaneous playback. At present, there are many video file packaging formats such as WMV, RMVB, MPEG, AVI, and FLV. With the development of technology, there are currently many audio and video players and many video viewing websites, but the compatibility of different players or video websites is limited, that is, the video file formats supported for playback are limited, so it is often necessary to play the video before playing. Convert video files in a format that cannot be played directly into another video package format to adapt to different network bandwidths, different terminal processing capabilities and diff...
