Abstract

The invention discloses a multimedia data stream processing method. The method comprises the following steps: decoding an input multi-path multimedia data stream through a decoder to obtain a video frame picture of the multi-path multimedia data stream; selecting a target video frame picture input into a filter from the video frame pictures of the multi-path multimedia data stream through a data selector; judging whether the target video frame picture is modified through a filter or not through a frame judgment module; when it is judged that the target video frame picture is not modified through the filter, judging whether parameter information in the target video frame picture is the same as parameter information of the target multimedia data stream or not through a frame judgment module; and when the parameter information in the target video frame picture is judged to be the same as the parameter information of the target multimedia data stream, outputting undecoded video binary data corresponding to the target video frame picture to a streaming media server. According to the invention, recoding of the high-quality input video stream can be avoided, and the quality of the output stream is improved.

Description

Technical field [0001] The present application relates to the field of video technology, and more particularly to a multimedia data stream processing method and device. Background technique [0002] Live business uses a cloud broadcast station service when editing, switching, mixing with multiple road-cast files or live stream media. Specifically, after the multiple input video streams (including audio and video signals) are decoded, the block operator is input by the data selector in the editing module, and then the specified input audio and video signal is edited by editing modules. The filter is filtered, and the filtered signal is input to the encoder for compression, and then the compressed video stream is transmitted to the streaming server. [0003] However, the inventors have found that since the encoding parameters of the video streams of different inputs may vary, the audio and video signal data processed after the editing module will be unified to encode the same set o...
