Problems solved by technology

[0007] Most of the existing third-party conversion algorithms involve copyright, and high fees need to be paid when using them. Long-term use is not conducive to reasonable cost control, and third-party conversion algorithms are different, and there are some restrictions on video maintenance and decoding in the later stage. It is not conducive to the improvement of App experience

Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0041] like figure 1 As shown, the method for synthesizing video from pictures according to the present invention comprises the following steps:

[0042] Image preprocessing, obtain image duration and size information,

[0043] Video data preparation, including:

[0044] Generate an AVAssetWriter for writing images and audio into a complete video file,

[0045] Generate AVAssetWriterInput for receiving data and configured to handle the specified media type,

[0046] When AVAssetWriterInput can accept image data, before the total number of frames is reached, continue to obtain the current frame image and generate the image pixel buffer PixelBuffer. If the total number of frames has been reached, generate a video.

[0047] Generate a pixel buffer adapter PixelBufferAdaptor, add PixelBuffer to the adapter and set the display time,

[0048] Add WriterInput t...

Abstract

The invention relates to a method for synthesizing a video from pictures. The method comprises the steps of picture preprocessing, acquisition of the duration and size information of the pictures andpreparation for video data. The method comprises the following specific steps: generating AVAssetWriter; generating AVAssetWriterInput; when the AVAssetWriterInput can receive picture data and beforea total frame number is reached, continuously acquiring a current frame of picture; generating a picture pixel buffer; if the total frame number is reached, generating a video; generating a pixel buffer adaptor; adding the pixel buffer to the adapter and setting display time; adding the WriterInput into Writer; and starting to write startWriting. The method has the advantages of unified algorithm,clear flow, high compatibility, rapid conversion of a GIF picture into a required video, unified output format, easiness in later period adjustment, higher user experience and higher APP developing efficiency.

Description

technical field [0001] The invention relates to the technical fields of image (picture) processing and video production, in particular to a method for synthesizing video from pictures. The pictures are especially GIF pictures. Background technique [0002] Video (Video) generally refers to various technologies that capture, record, process, store, transmit and reproduce a series of still images in the form of electrical signals. When continuous image changes exceed 24 frames per second, according to the principle of persistence of vision, the human eye cannot distinguish a single static image; it looks like a smooth and continuous visual effect, such a continuous image is called a video. [0003] The development of network technology also enables video documentary segments to exist on the Internet in the form of streaming media and can be received and played by computers. [0004] Considering the bandwidth priority of network transmission, many online videos are actually G...
