Problems solved by technology

However, it is very inconvenient for the user to know the situation of the playing content at a glance only from the playlist in text form.
Moreover, the existing playlists in the form of text are relatively rigid in display, not vivid enough, and cannot intuitively reflect the content of the video.

specific Embodiment

[0047] see figure 1 Shown is a specific embodiment of a method for displaying a playlist in graphic mode described in this application, the method comprising:

[0048] Step 101, setting the trial selection time interval and the maximum number of attempts when selecting video frames, and the brightness threshold range of the image;

[0049] Step 102, selecting the starting point of the video frame from the source video file, and jumping the video data to the video key frame before the starting point according to the selected starting point of the video frame;

[0050] Step 103, separating the video file data corresponding to the video key frame from the source video file data, and converting the video key frame into an image of a predetermined size and a predetermined format;

[0051] Step 104, calculate the average brightness value of the image, and judge whether the average brightness value of the image is within the range of the brightness threshold, if the average brightne...

Embodiment 2

[0069] see figure 2 Shown is a specific embodiment of a system for displaying a playlist in graphic mode described in the application, the system comprising: a parameter setting module 10, a video frame starting point selection module 20, a video frame conversion module 30, and an image brightness value calculation module 40, video thumbnail selection module 50 and control module 60,

[0070] The parameter setting module 10 is used to set the trial selection time interval and the maximum number of attempts when the video frame is selected, and the brightness threshold range of the image;

[0071] The video frame starting point selection module 20 is used to select the starting point of the video frame from the source video file, select the starting point of the video frame according to the selection, and jump the video data to before the starting point video keyframes;

[0072] The video frame conversion module 30 is used to separate the video file data corresponding to the...

Embodiment 3

[0082] The following provides an application embodiment of the method for displaying a playlist in graphic and text mode according to the present invention.

[0083]This application can set the playlist in the form of variable mode switching, which can not only display the traditional text playlist, but also change it to a graphic mode list. When implementing a graphic-text mode playlist, select a frame of image from the source video file as a video thumbnail. After the player UI completes the playlist area, this solution uses the thumbnail length and width information provided by the UI. And source video file path and thumbnail save path to generate a thumbnail corresponding to the source video, load it into the playlist for display.

[0084] The above thumbnail is actually a certain frame in the source video file. The main idea is to select a certain frame, then transcode the frame according to the length and width required by the UI layer, and display it in the playlist.

Abstract

The invention discloses a method and a system for displaying a playlist in an image-text mode. The method comprises the following steps: setting a selection trial time interval and maximum trial times during selection of a video frame and a brightness threshold range of an image; selecting an initial point for selecting the video frame from a source video file, and skipping video data to a video key frame before the initial point; separating video file data corresponding to the video key frame from source video file data, and converting the video key frame into an image of a predetermined size and a predetermined format; calculating an average brightness value of the image, and selecting an image which satisfies the brightness threshold range or selects an image with highest brightness when the image which satisfies the brightness threshold range is unavailable to serve as a video thumbnail; transcoding a video frame corresponding to the video thumbnail of the selected source video file into a YUVJ420P format and saving the transcoded video frame; and generating a video thumbnail corresponding to the source video file according to an address of the video frame and a corresponding source video file ID (Identity), and loading the video thumbnail to the playlist to display the video thumbnail.

Description

technical field [0001] The present application relates to the technical field of setting video playlists, in particular, to a method and system for displaying playlists in graphic and text mode. Background technique [0002] During the video playback process, some content information will be intercepted from the playback content to form a playlist for the user to choose the playback content. The current playlists are playlists in the form of text, and the content stored in the list is basically the content of each video in the table. name. However, it is very inconvenient for the user to be difficult to know the situation of the playing content at a glance only from the playlist in text form. Moreover, the existing playlist in the form of text is relatively rigid in display, not vivid enough, and cannot intuitively reflect the video content. [0003] Therefore, how to conveniently display the brief introduction of the content picture of the video at the position of the pla...
