Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of an image obtaining method according to an embodiment of the present invention, where the embodiment is applicable to a scene in which a first frame image of a target video is captured. The method may be performed by an image acquisition apparatus, which may be implemented by means of software and/or hardware.
As shown in fig. 1, the method specifically includes the following steps:
The response event associated with video playing specifically refers to processing logic for loading a video from a server and playing the video at a client. The response event includes at least one of: metadata loaded event metadata, video data loaded event loaded data, allowed play events can-play, time update event update, start play event play, and wait for event waiting.
The metadata loading event loaded metadata is triggered when the video metadata is loaded, and the video metadata specifically refers to data describing a video, such as information of a storage path, name information, or playing time length of a video file. However, the video metadata does not include the video content itself, and thus it is not suitable to immediately acquire the first frame image of the target video when it is monitored that the metadata loading event loaded metadata is triggered.
The video data loading event loaded data is triggered when the loading of the first frame image data of the video is finished, and it can be understood that the first frame image of the video can be immediately acquired when the video data loading event loaded data is monitored to be triggered.
The play-allowed event can-play is triggered when the video can start playing, that is, the number of frames loaded is determined according to the number of the uploaded video frames, and then the requirement of the play picture is met, and the play-allowed event can-play is triggered when the requirement of the play picture is met, so that the image acquisition time is determined by monitoring the play-allowed event can-play, and the first frame image needs to be further determined, because the play-allowed event can-play may have the multi-frame video image loaded when being triggered, and not only the first frame video image.
The time update event time update is typically triggered when the playing position of the video changes. The play starting event play is triggered when the video starts to play, and the waiting event waiting is triggered when the video is played but the next picture is not buffered, so that the method is suitable for inserting the small advertisements.
By the above description of the response events, for example, the monitoring the response event associated with the video playing to determine the image acquisition time includes:
and determining the moment when the monitored video data loading event loaded data is triggered as the image acquisition moment.
Or, determining the moment when the metadata loading event loaded metadata is triggered;
and determining the image acquisition time according to the size of the target video and the current network state based on the time.
Generally, after a metadata loading event loaded metadata is triggered, video content starts to be loaded, the loading speed is related to the current network state and the size of a target video, and the relation among the loading speed, the current network state and the size of the target video can be counted through continuous business practice, so that the time sequence relation between the moment when a first frame video image is loaded and the moment when the metadata loading event loaded metadata is triggered is further determined, and the image acquisition moment is determined according to the moment when the metadata loading event loaded metadata is triggered.
And 120, acquiring a first frame image of the target video based on a set strategy at the image acquisition time.
The setting strategy comprises graph drawing, specifically, for example, a graph drawing tool canvas is used for acquiring a first frame image of a target video. The canvas is a new label in the HTML5, is used for generating an image in real time on a webpage, can operate the image content, is a bitmap which can be operated by JavaScript, and the canvas object represents an HTML canvas element, and can realize the support of the scripted client drawing operation through an interface.
Specifically, the acquiring a first frame image of the target video based on the graph drawing canvas at the image acquisition time includes:
acquiring an attribute ref node at the image acquisition time;
determining the width and height of the first frame image according to the attribute ref node;
acquiring video data of a video data loading event loaded data at the image acquisition moment;
drawing the first frame image based on a graphics drawing canvas according to the width, height and video data; finally, the source object src of a canvas can be obtained through canvas.
And step 130, judging the effectiveness of the first frame image.
And 140, if the first frame image is an effective image, displaying the first frame image, otherwise, displaying the set image.
Sometimes, due to the poor quality of the target video or the influence of some other factors, the captured first frame image is often not very satisfactory, and an invalid image such as a pure black image, a transparent image, or a white image may appear in the conference. Therefore, it is necessary to identify the validity of the image. It has been found through experimentation that the color values of the transparent image are all 0, the color values of the white image are all 255, and the color values of the black image show an unexpected number 238, which is a color value biased toward 255 white, because white and transparent colors are not excessive, and black is excessive, which is a problem when canvas draws.
Based on the service characteristics, for example, the determining the validity of the first frame image includes:
and judging the effectiveness of the first frame image according to the color value corresponding to the first frame image.
Specifically, an array composed of 8-bit unsigned integers with values fixed in the interval of 0-255 can be represented by a Uint8 claspedarray (8-bit unsigned integer fixed array) typed array; if a value outside the [0,255] interval is specified, it will be replaced with 0 or 255; if a non-integer is specified, it will be set to the nearest integer. The contents of the array Uint8 claspedarray are initialized to 0. Once the Uint8ClampedArray is created, the elements in the array may be referenced using the method of the object, or using standard array index syntax (i.e., using square bracket notation). According to the statistical characteristics of the color values of the invalid image, only one image between 0 and 200 is needed to be judged and identified whether the acquired first frame image is the valid image, and the acquired first frame image is the invalid image as long as no numerical value exists in the array.
The set image is a preset default image, the set image is an image irrelevant to the target video, and the set image can be understood as a degraded image or a bottom-holding image of the first frame image, so that a user side is prevented from displaying blank images, the method is suitable for all videos, and the set image is called for displaying if the first frame image is not acquired from the videos.
According to the technical scheme of the embodiment, the image acquisition time is determined by monitoring the response event associated with the video playing; the first frame image of the target video is acquired based on the graph drawing canvas at the image acquisition moment, so that the first frame image of the video is accurately acquired, and the consumption cost of the system performance is reduced.

Wherein explanations of the same or corresponding terms as those of the above-described embodiments are omitted.
Referring to fig. 2, the image acquiring method provided in this embodiment specifically includes the following steps:
The metadata loading event loaded metadata is triggered when the video metadata is loaded, where the video metadata specifically refers to data describing a video, such as information of a storage path, name information, or playing time length of a video file. However, the video metadata does not include the video content itself, and thus it is not suitable to immediately acquire the first frame image of the target video when it is monitored that the metadata loading event loaded metadata is triggered.
And step 220, determining the image acquisition time according to the size of the target video and the current network state based on the time.
Generally, after a metadata loading event loaded metadata is triggered, video content starts to be loaded, the loading speed is related to the current network state and the size of a target video, and the relation among the loading speed, the current network state and the size of the target video can be counted through continuous business practice, so that the time sequence relation between the moment when a first frame video image is loaded and the moment when the metadata loading event loaded metadata is triggered is further determined, and the image acquisition moment is determined according to the moment when the metadata loading event loaded metadata is triggered.
And step 230, acquiring a first frame image of the target video based on a set strategy at the image acquisition time.
And 240, judging the effectiveness of the first frame image.
And 250, if the first frame image is an effective image, displaying the first frame image, otherwise, displaying a set image.
