Problems solved by technology
[0002] With the development of technology, various audio and video formats and related resources emerge in an endless stream to meet people's entertainment and life needs. However, it is difficult for the current playback platform to cover all formats of audio and video file formats. On some operating systems A certain audio and video file format may not be supported. For example, m3u8 is an index file (playlist) format, and the index file contains a series of media files in TS (Transport Stream, transport stream) format. Android3.0 operation The system itself cannot parse the m3u8 format, so the media file cannot be played
[0003] Currently, FFmpeg (an open source and free cross-platform video and audio streaming solution) tool can be used for format conversion. However, FFmpeg relies on hardware devices, such as CPU (Central Processing Unit, central processing unit), etc., and the converted files are relatively large. Large, increasing the storage pressure

Embodiment Construction
[0049] 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.
[0050] Currently, FFmpeg tools can be used for format conversion, but FFmpeg relies on hardware devices and the converted files are large, which increases storage pressure. In the technical solution provided by the embodiments of the present invention, by obtaining the index file of the first video stream, the video fragment files are downloaded according to the playback sequence and download address of the video fragment files in the index file, and the video fragment files are parsed to obtain video frame data and audio frames Data, video frame data and audio frame data are respectively encoded, and the encoded video frame data and audio frame data are encapsulated...

The invention discloses a method and device for processing video. The method and device for processing the video are used for playing media files corresponding to index files of the format of m3u8 on an Android operation system. The method for processing the video comprises the steps of acquiring the index file of a first video stream, downloading fragmented video files according to the playing sequence and the downloading address of the fragmented video files in the index files, parsing the fragmented video files to acquire video frame data and audio frame data, respectively encoding the acquired video frame data and the acquired audio frame data and packaging the encoded video frame data and the encoded audio frame data into a second video stream in the format of a RPT according to the playing sequence. According to the technical scheme, the fact that the second video stream is played on the Android operation system by using RTSP service is achieved, the second video stream is small, and therefore storage space is saved.
