Abstract

The invention discloses a PIS streaming media service method based on capturing and secondary encoding after playing. The method comprises the following steps of: A, enabling a streaming media serverto obtain audio and video data from a local file or a decoder; B, decoding and playing the video data; C, obtaining pixel data of a designated area; D, capturing the audio data through a slave sound card; E, encoding the captured pixel data and audio data. The method has the beneficial effects that 1, the design is simple, different packaged and encoded video streams do not need to be converted, 2, special effects such as station captions, subtitles and filters can be conveniently added to the video streams, 3, the content of the stream pushing video is directly monitored at a server side, and4, the method has the capability of dynamically adjusting the stream pushing code stream.

Description

technical field [0001] The invention relates to the technical field of streaming media, in particular to a PIS streaming media service method based on capture and secondary encoding after playback. Background technique [0002] In the urban rail transit industry, the Passenger Information System (PIS) is a necessary part of information construction, and it generally consists of a central subsystem, a station subsystem, an on-board subsystem, and a network subsystem. The central subsystem (as a server) pushes train information, live video streams, advertisement information, etc. to the playback controller (as a client) of the station through network technology for synthesis and playback. [0003] The streaming media server is an indispensable part of live video broadcasting. The main function of the streaming media server is to transmit video files to the client for online playback through streaming protocols (RTP / RTSP, MMS, RTMP, etc.) without waiting for the entire file to ...
