Problems solved by technology

However, using these methods will inevitably make the barrage "thin", and some users do not like this experience, because a "thicker" barrage can make the audience feel more of a sense of participation and even a sense of identity
[0004] On the other hand, the essence of the above-mentioned methods is that they only provide a method for audience-side barrage selection, which is not directly related to the content of the video itself, and video providers who know more about video content lack effective means to analyze the barrage. to adjust the display

Embodiment 1

[0067] After the video upload user (UP master) uploads the video, he can choose to set a barrage mask for the video. Bullets in the area of ​​this mask have some transparency or are completely hidden. The user can use the mask drawing tool to draw vector graphics on the range of the video area (you can draw regular graphics such as rectangles and circles with tools; you can also draw irregular graphics such as polygons with pen tools), and can adjust the position of the vector graphics . And as Figure 6 As shown, further set the barrage transparency of each vector graphic.

[0068] After you finish painting one or more masks, save all the masks and their settings as a mask group.

[0069] Viewers can choose to turn on the bullet screen mask when watching this video. At this time, when the barrage passes through the vector graphic area in the mask group, it will appear as Figure 7 As shown, there is a certain transparency effect, even as Figure 4 or Figure 5 Shown is...

Embodiment 2

[0075] The difference from Embodiment 1 is that the attribute setting of the vector graphics includes not only transparency, but also the appearance time and disappearance time of the vector graphics (not applicable for live broadcast) and whether to soften (feather) the edges. The time setting can make the mask application more flexible, soften the edge effect such as Figure 5 As shown, the display effect when applying the mask can be made less obtrusive.

Embodiment 3

[0077] The difference with the above embodiment is that when a mask group such as Figure 8 As shown in , when there are two or more vector graphics overlapping with each other (the position overlaps and is valid at the same time), the bullet chatting through the overlapping area has the following Figure 9 The display effect of the overlay of multiple masks shown. For example, when two masks overlap, one of which has a transparency of 30% and the other has a transparency of 50%, the transparency of the bullet chatter passing through the overlapping area will be 80%. Of course, when the superimposed transparency is equal to or greater than 100%, it will be displayed as a hidden barrage.

[0078] Using the video bullet chat mask drawing method and the corresponding bullet chat playing method of the invention, first in the mask drawing method, the video provider can draw vector graphics, set its attributes and display effects, and generate a mask group; Then load the mask grou...

Abstract

The invention relates to a video barrage mask drawing method and device, a barrage playing method and device, and a computer readable storage medium, belonging to the field of Internet technology. Themethod comprises the steps of drawing a vector graphic by a video provider, setting attributes and the display effect thereof, and generating a mask group; then loading the mask group in the playingmethod, and determining the display effect when barrages pass through the vector graphic according to the mask group. Therefore, the barrage playing method provided can be used by the video provider,and can distinguish the display of the barrages in different areas such that the barrages have certain transparency or even are hidden when passing through the vector graphic areas, the video contentsof the vector graphic areas are not covered without reducing the number of the barrages, and the watching effect of audiences is ensured. The video barrage mask drawing method and device, the barrageplaying method and device, and the computer readable storage medium are simple in application, better in use experience, wide in application range and quite low in implementation cost.

Description

technical field [0001] The present invention relates to the field of Internet technology, in particular to the field of network video technology, and specifically refers to a video bullet-screen mask drawing method, bullet-screen playing method, device and computer-readable medium. Background technique [0002] Bullet chat refers to a phenomenon in which a large number of comments are presented in the form of subtitles when watching a video, and the comments and the video are presented on the same screen. A large number of comments floating above the video are like dense shells, hence the name barrage. The barrage will be displayed on the video in real time as the video plays, so that viewers can see the barrage sent by other viewers and themselves when watching the video. Form a new network social form based on video watching and surrounding video content. [0003] However, in the case of too many bullet screens, more video content is blocked, which will also make the vie...
