Problems solved by technology

When the video player performs pause playback and positioning playback operations, all modules in the video player need to switch from GST_STATE_PLAYING (running state) to GST_STATE_PAUSED (pause state), and then switch from GST_STATE_PAUSED (pause state) to GST_STATE_PLAYING (running state ), the defect of this method is that it takes a long time from the start of the operation to the completion of the operation response, and the response speed is slow

Abstract

The invention discloses a video play control device. The video play control device comprises a play control module and a video pipeline. The video play control device also comprises a hardware abstraction layer module, a hardware decoding module and a hardware display module. The hardware abstraction layer module is used for receiving information of the play control module and / or the video pipeline, and carrying out control operation on the hardware decoding module and / or the hardware display module according to the information. The invention also provides a video play control method. Through control operation, carried out by the hardware abstraction layer module, on the hardware decoding module and the hardware display module, the hardware decoding module and the hardware display module are allowed to be arranged outside the video pipeline, thereby reducing state switching of internal modules in the video pipeline, and reducing consumed time.

Description

technical field [0001] The present invention relates to the field of video playing, in particular to a video playing control device and method. Background technique [0002] Watching videos on the Internet has become one of the indispensable entertainment activities in people's daily life. Existing video players usually use video pipelines to play video files, see figure 1 , the video pipeline includes a data source module, a demultiplexing module, a decoding module and a display module, and each module corresponds to four states, namely GST_STATE_NULL (default state), GST_STATE_READY (ready state), GST_STATE_PAUSED (pause state) and GST_STATE_PLAYING (Operating status). When the video player performs pause playback and positioning playback operations, all modules in the video player need to switch from GST_STATE_PLAYING (running state) to GST_STATE_PAUSED (pause state), and then switch from GST_STATE_PAUSED (pause state) to GST_STATE_PLAYING (running state ), the defect ...
