Problems solved by technology

[0006] In the above technical solution, by generating and displaying a video stream playback interface based on QML, then receiving the gstreamer video stream, and decoding the gstreamer video stream, Convert the image data; then store the image data in the QImage type object of the video presentation class, and then draw the QImage type object to the QML-based video stream playback interface for playback, thus realizing the QML-based gstreamer video stream The playback function does not need to use QT or third-party gstreamer plug-ins for QML to display video, thus solving the problem that the operating environment does not support or the support effect is poor when playing gstreamer video streams on different systems or hardware platforms (especially embedded platforms) question

[0028] see figure 1 , which is a schematic flowchart of the video stream playing method provided in the first embodiment of the present invention. The video streaming playing method comprises the following steps:

[0029] S10, generating and displaying a QML-based video stream playback interface;

[0030] S20, receiving the gstreamer video stream, and decoding and converting the gstreamer video stream to obtain image data;

[0031] S30, storing the image data into a QImage type object of the video presentation class; and

[0032] S40. Draw the QImage type object to the QML-based video stream playback interface for playback.

[0033] Specifically, the QML-based video stream playback interface in step S10 is, for example, a video stream playback window presented by using QML.

[0034] In a specific implementation manner, the step S20 specifically includes: receiving the gstreamer video stream through the appsink plug-in of the gstreamer pipeline of the video playing class, and...

[0046] Such as Figure 4 As shown, the second embodiment of the present invention provides a video stream playing device 300 . The video stream playback device 300 includes, for example, an interface generation and display module 310 , a video stream processing module 320 , an image data storage module 330 , and an interface drawing module 340 .

[0047] Specifically, the interface generation and display module 310 is used to generate and display a QML-based video stream playback interface.

[0048]The video stream processing module 320 is used for receiving the gstreamer video stream, decoding and converting the gstreamer video stream to obtain image data.

[0049] The image data storage module 330 is used to store the image data into a QImage type object of the video presentation class.

[0050] The interface drawing module 340 is used for drawing the QImage type object to the QML-based video stream playback interface for playing.

[0051] In a specific implementation man...

Abstract

The embodiment of the invention discloses a video stream playing method, device and system and a storage medium. The video stream playing method comprises the following steps: generating and displaying a QML-based video stream playing interface; receiving a greader video stream, decoding the greader video stream, and converting the greader video stream to obtain image data; storing the image datainto a QImage type object of a video presentation class; and drawing the QImage type object to the QML-based video stream playing interface for playing. According to the embodiment of the invention, the rendering relationship between the greader video stream and the QML interface is established in a user-defined manner, and the greader plug-in for displaying the video by adopting QT or other thirdparties and aiming at the QML is avoided, so that the problems that the operation environment is not supported or the supporting effect is poor when different systems or hardware platforms (particularly embedded platforms) play the greader video stream are solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a method for playing video streams, a device for playing video streams, a system for playing video streams and a storage medium. Background technique [0002] At present, the embedded GUI (graphical user interface) design based on LINUX usually adopts QT to build the interface, and it is often considered to play the gstreamer video stream on the interface developed by the cross-platform C++ graphical user interface application development framework QT developed by Qt Company, but , because different from the QT Graphical User Interface (GUI, Graphical User Interface) using software rendering, the descriptive scripting language QML uses GPU hardware rendering technology, so the gstreamer video codec plug-in adapted by ARM chip manufacturers is usually adapted to QT GUI The window is not suitable for the QML window. As a result, the gstreamer video codec plug-in does not s...
