A video file processing method and device are disclosed. The method comprises the following steps: the first sequence parameter set, the first image parameter set and the first group of image frames corresponding to the first video file are respectively encapsulated in a network abstraction layer to obtain a first network abstraction layer unit, a second network abstraction layer unit and a thirdnetwork abstraction layer unit corresponding to the first video file; a first network abstraction layer unit, the second network abstraction layer unit and the third network abstraction layer unit aresequentially inputted into a preset video file encapsulator to obtain a total video file including a first video file, wherein the preset video file encapsulator includes a network abstraction layerunit corresponding to other video files to be spliced with the first video file. The method realizes the operations of decoding and re-encoding a plurality of image frames when the video file is spliced, thereby improving the processing speed of the video file, reducing the waiting time of the user and improving the user experience.
Description
technical field [0001] The present application relates to the field of multimedia technologies, in particular to a video file processing method and device. Background technique [0002] Nowadays, smart devices generally have a video shooting function, and users can perform shooting operations at any time, and can also edit and process multiple video files shot to obtain video files they are satisfied with. For example, splicing or cropping video files, etc. [0003] In practical applications, in order to reduce the size of the video file, the video file is usually compressed and encoded. Commonly used encoding methods include: H.264, H.265, etc. Taking the encoding method as H.265 as an example, when encoding a video file, a sequence parameter set (Sequence Parameter Set, referred to as: SPS), a picture parameter set (Picture Paramater Set, referred to as: PPS) and a set of image frame. When the encoding parameters used in video files are different, the SPS and PPS gener...
