specific Embodiment

[0026] Such as figure 1 , figure 2 , image 3 and Figure 4 Shown, specific embodiment of the present invention is as follows:

[0027] 1: The control module downloads the playlist and stores valid information. The playlist contains the seamless playback flag (AWPLAY_SEAMLESS), which is used to distinguish whether to respond to the seamless playback network or the normal network data stream, the live broadcast / on-demand flag (AWPLAY_ENDLIST), and the fragmented file Duration (AWPLAY_STREAM), the sequence of the first fragment of the current list (AWPLAY_SEQUENCE), used to distinguish whether to update the local list identifier, fragment video name (1.MP4,...,2.MP4). Such as image 3 Shown is a playlist structure diagram.

[0028] 2: In response to the playback operation, load the i-th segment as the first playback segment according to the playback timestamp, start the buffer module, and the buffer module sets the first video data buffer and the second video data buffer, ...

Abstract

The invention discloses a segmental network video seamless playing method and device. The method comprises the steps of: A1, downloading a playing list; A2, obtaining a storage address of each played segment based on the playing list; A3, setting a first video data buffer region and a second video data buffer region; A4, respectively downloading and buffering video data of adjacent played segments into the first video data buffer region and the second video data buffer region based on the sequence of the played segments, and decoding the video data for playing. The device comprises a control module, a buffer module and a decoding module, wherein the control module, the buffer module and the decoding module are connected in sequence; the control module is used for downloading the playing list, calculating a hop-broadcasting time stamp and performing video hop-broadcasting treatment; the buffer module is used for arranging the first video data buffer region and the second video data buffer region, and buffering the video data; the decoding module is used for obtaining the video data alternately in the first video data buffer region and the second video data buffer region, and decoding the video data.

Description

technical field [0001] The invention relates to the technical field of video playback, in particular to a segmented network video seamless playback method and device. Background technique [0002] With the increase of network bandwidth and the wide application of OTT (OTT) and tablet PCs, the user experience requirements for playing videos on the network are also increasing. The main feature of streaming media technology is to carry out real-time and continuous transmission of multimedia data in the Internet based on IP protocol in the form of "streaming". While playing the media data already received in the zone, the remaining part of the media stream is still continuously delivered from the server to the client, which is the so-called "play while downloading". Existing network video collection resources include TV dramas and movies, many of which are cut into fragments ranging from a few minutes to more than ten minutes. When multimedia playback terminals play network vid...
