Problems solved by technology

[0002] After the development of multimedia processing technology in recent years, frame rate conversion is not only used to convert between video formats and standards, but also to enhance the overall quality of video. Higher frame rates will be used to provide higher quality home An important component of video, however, some of the existing video cannot be used at a higher frame rate, so frame rate conversion becomes very necessary

Embodiment Construction

[0062] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0063] figure 1 It is a flowchart of a conversion method of a H264 video frame rate in an embodiment of the present invention, such as figure 1 As shown, including the following steps S11-S13:

[0064] Step S11, acquiring H264 video frames within a unit duration.

[0065] Wherein, the unit duration is, for example, 1 second.

[0066] Step S12, decoding the H264 video frames within the unit duration to obtain decoded RAW video frames.

[0067] Step S13, performing an equal interval conversion operation on the current frame rate of the RAW video frame.

[0068] After the frame rate conversion of the H264 video frames in the unit duration is completed, the frame rate...

Abstract

The invention discloses a H264 video frame rate conversion method and device, which are used to realize the frame rate conversion of the H264 standard video frame. The method includes: acquiring H264 video frames within a unit time length; decoding the H264 video frames within the unit time length to obtain decoded RAW video frames; performing equidistant conversion operations on the current frame rate of the RAW video frames . This technical solution decodes the H264 video frames within a unit duration, and then performs frame rate conversion on the decoded RAW video frames, and realizes the frame rate conversion of the H264 standard video frames, thereby meeting the video requirements for different frame rates. .

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for converting an H264 video frame rate. Background technique [0002] After the development of multimedia processing technology in recent years, frame rate conversion is not only used to convert between video formats and standards, but also to enhance the overall quality of video. An important component of video, however, some of the existing videos cannot be used at a higher frame rate, so frame rate conversion becomes very necessary. For videos with different encoding standards, how to perform frame rate conversion in a targeted manner has become a very important research topic in the multimedia field. Contents of the invention [0003] The present invention provides a H264 video frame rate conversion method and device, which are used to realize the frame rate conversion of the H264 standard video frame. [0004] The present invention provides a co...
