In order to solve the problem that a video cannot be normally played after a video occlusion picture is hidden in advance due to a certain time delay from when a video app receives a callback message to when the video is normally played, an embodiment of the present application provides a method for controlling a video occlusion picture on a smart television, where as shown in fig. 3, the method may include:
301. according to the playing event generated on the video of the intelligent television, the intelligent television sends a playing request to a server corresponding to the video.
When a user needs to watch a certain video in a video app installed on the smart television, or the user needs to switch the resolution of the video, or the user needs to drag the video from a current playing position to a new playing position, and the like, the user can operate the video. At this time, the smart television may generate a play event on the video according to the operation of the user, and according to the play event, call a communication interface in the video app, that is, an SDK provided by a content service provider, and send a play request to a server corresponding to the video, for example, a server of a corresponding content provider, through the communication interface, where the play request carries a video identifier of the video, and is used to obtain video data corresponding to the video identifier from the server corresponding to the video, where the video refers to a video played in a video window in a player of the smart television or a video to be played.
It should be noted that, in the embodiment of the present application, operations performed by a user are different, playing events generated by the smart television are different, and types of playing requests sent by the smart television to the server corresponding to the video according to the different playing events are also different. Specifically, the play request may be any one of a start play request, a resolution switching request, a drag request, a fast forward request, and a fast reverse request.
302. The intelligent television displays a video occlusion picture.
303. And the intelligent television receives a response message returned from the server according to the video identifier of the video carried in the playing request.
After sending the playing request to the server corresponding to the video, the smart television may receive a response message returned from the server. At this time, the smart television may generate different callback messages according to different response messages, and specifically may execute the following step 304 or step 305:
304. and when the video data corresponding to the video identification exists in the response message, the smart television generates a first callback message.
Wherein the first callback message is used to notify the video app of successful receipt of the video data. When the video data corresponding to the video identification exists in the response message, the third-party SDK in the smart television generates a first callback message after receiving the video data, and the video app is callback based on the first callback message, so that a video player corresponding to a video window in the video app can process the video data.
305. And when the response message does not include the video data corresponding to the video identification, the smart television generates a second callback message.
And the second callback message is used for notifying the video app that the third party SDK does not receive the video data. And when the response message does not include the video data corresponding to the video identification, a third-party SDK in the smart television generates a second callback message and calls back the video app.
306. And inquiring the playing progress by the smart television.
After the smart television sends the play request to the server corresponding to the video in step 301 and at any time before the callback message is generated in step 304 or step 305, the smart television starts an inquiry thread for inquiring the play progress, obtains the time for starting the inquiry thread, records the time as the start time, and inquires the play progress at the start time. In a first possible implementation manner, after obtaining the start time and inquiring the play schedule corresponding to the start time, the smart television may wait for a period of time before starting the periodical inquiry of the play schedule, that is, successively inquiring the play schedule and the play time corresponding to the play schedule, at this time, the first inquired play schedule is the play schedule corresponding to the start time, the previous play schedule is the first inquired play schedule when starting the periodical inquiry of the play schedule, and the later play schedule is the play schedule inquired after a period of time interval corresponding to the previous play schedule. In a second possible implementation manner, the smart television may periodically query the playing schedule from the start time, at this time, the playing schedule queried for the first time and the previous playing schedule are both playing schedules corresponding to the start time, and the later playing schedule is the playing schedule queried after the start time interval is one period.
After the intelligent television queries the playing progress and the corresponding playing time in sequence, the difference value between the rear playing progress and the front playing progress in the playing progress can be determined. If the difference is greater than 0, the smart tv determines that the playing schedule is changed, and at this time, the smart tv may perform the following step 307. If the difference is less than or equal to 0, the smart tv determines that the playing progress has not changed, and at this time, the smart tv may perform the following step 308.
307. And when the change of the playing progress is determined, the smart television removes the video occlusion image according to the first callback message.
When it is determined that the playing progress changes, that is, when it is determined that the difference between the rear playing progress and the front playing progress is greater than 0, the smart television may determine a first difference between the playing time corresponding to the rear playing progress and the playing time corresponding to the front playing progress. When the first difference is smaller than the first preset threshold, the smart television can continue to inquire the playing progress of the next period. When the first difference is greater than or equal to the first preset threshold, the smart television may remove the video occlusion map displayed on the video according to the first callback message in step 304, and start to play the picture of the video data.
It should be noted that, in the embodiment of the present application, because a certain time delay exists between the generation of the callback message by the smart television and the playing of the video data, in order to avoid a problem that the determination of the change of the playing progress is inaccurate due to factors such as premature starting of the query thread, a first preset threshold may be stored in the smart television in advance, and the first preset threshold may be greater than or equal to the time delay, so as to ensure that the playing progress changes really. Therefore, when the playing progress is determined to change, the intelligent television compares the first difference value with the first preset threshold value, and the first preset threshold value is 300 milliseconds to 1 second, so that the accuracy of the result of the change of the playing progress is ensured, and the user experience is improved.
For example, in a scene in which a user needs to drag a video being played in a video window of the smart television from a current playing position to a new playing position, the smart television may send a drag request to a server corresponding to the video according to a generated playing event and display a video occlusion map in the video window. And the smart television receives a response message returned from the server, and generates a first callback message on the assumption that video data corresponding to the video identification exists in the response message. Fig. 4 is a schematic diagram of a thread periodically querying a playing schedule, as shown in fig. 4, assuming that a starting time of the smart television starting the query thread is T0, the smart television waits for a period of time after T0, starts to query the playing schedule and a corresponding playing time in sequence, assuming that the period of querying the playing schedule is T, T is set to 100 milliseconds, and a first preset threshold is 3T, the smart television may first obtain a playing time T1, and query a previous playing schedule P1 at T1, and then query a later playing schedule P2 at T2T 1+ T after the period T, at this time, it is assumed that P2-P1>0, and T2-T1T is T, which is less than the first preset threshold 3T, the smart television continues to query a playing schedule P3 at T3T 2+ T, it is assumed that P3-P2 >0, and T3-T1T is less than the first preset threshold 3T, the smart tv continuously queries the playing progress P4 when T4 is T3+ T, and assuming that P4-P3 is greater than 0 and T4-T1 is 3T, which is equal to the first preset threshold value 3T, the smart tv may remove the video occlusion map according to the first callback message, and start playing the picture of the video data from the new playing position, and simultaneously update the progress bar of the video data.
For another example, in a scene where a user needs to switch the resolution of a video being played in a video window of the smart television, the smart television may send a resolution switching request to a server corresponding to the video according to the generated play event and display a video occlusion map in the video window. And the smart television receives a response message returned from the server, and generates a first callback message on the assumption that video data corresponding to the video identification exists in the response message. Fig. 5 is a schematic diagram illustrating that a thread periodically queries a playing progress, as shown in fig. 5, assuming that a start time of a query thread started by a smart television is T0, and the playing progress and a corresponding playing time thereof are sequentially queried from T0, assuming that a period of the query playing progress is T, T is set to 200 ms, and a first preset threshold is 1.5T, the smart television may first obtain a previous playing progress P1 at T0, and then, after the period T, query T1 ═ T0+ T later playing progress P2, at this time, assume P2-P1>0, and T1-T0 ═ T, which is less than the first preset threshold 1.5T, the smart television continues to query T2 ═ T1+ T playing progress P3, assumes P3-P2 >0, and T2-T0 ═ 2T, which is greater than the first preset threshold 1.5T, and the smart television may remove occlusion information according to the first video image graph, and starting to play the picture of the video data at the switched resolution, and simultaneously displaying prompt information for prompting that the user has successfully switched the resolution.
308. And when the playing progress is not changed, the intelligent television displays prompt information for indicating that the video data playing fails according to the second callback message.
When it is determined that the playing progress is not changed, that is, when it is determined that the difference between the rear playing progress and the front playing progress is less than or equal to 0, the smart television may determine a second difference between the playing time corresponding to the rear playing progress and the playing time corresponding to the first-time queried playing progress, and in the first possible implementation manner and the second possible implementation manner in step 306, the first-time queried playing progress is the playing progress corresponding to the starting time. When the second difference is greater than or equal to the second preset threshold, it indicates that the smart television may not obtain the video data, the smart television may end the query thread, and display a prompt message for indicating that the video data is failed to be played according to the second callback message in step 305, so that the user may know that the video data is failed to be played, perform a video selection operation, and improve user experience. When the second difference is smaller than a second preset threshold, the smart television can continue to inquire the playing progress of the next period.
It should be noted that, in the embodiment of the present application, since the change condition of the video data playing progress is affected by a plurality of factors (for example, factors such as the configuration of the whole device, the amount of the video data, and the loading speed of the player), the accuracy of determining the playing progress may be reduced, in order to improve the accuracy, a second preset threshold is stored in advance, and a ratio between the second preset threshold and the first preset threshold is between 10 and 30, which is an upper limit of a time when the smart television cannot respond to the playing request and the playing abnormality cannot last.
For example, in a scene in which a user needs to watch a video to be played in a video window of the smart television, the smart television may send a play start request to a server corresponding to the video according to the generated play event and display a video occlusion map in the video window. And the intelligent television receives a response message returned from the server, and generates a second callback message if the response message does not contain the video data corresponding to the video identification. With reference to fig. 5, assuming that the second preset threshold is 10 times the first preset threshold, that is, the second preset threshold is 15T, the smart tv may first obtain a previous playing progress P1 at T0, and then after the period T, query a later playing progress P2 at T1 ═ T0+ T, at this time, assume that P2-P1 ═ 0 and T1-T0 ═ T, which is less than the second preset threshold 15T, the smart tv continues to query a playing progress P3 at T2 ═ T1+ T, assume that P3-P2 ═ 0 and T2-T0 ═ 2T, which is less than the second preset threshold 15T, the smart tv continues to query a playing progress P4 at T5 ═ T2+ T, assume that P4-P3 ═ T630 and T3-T0, and T is less than the second preset threshold 9, and then continuously queries no change in the period T573 occur, until P16-P15 is equal to 0, and T15-T0 is equal to 15T, which is equal to the second preset threshold 15T, the smart television may end the query thread and display a prompt indicating that the video data playback has failed according to the second callback message.
According to the method for controlling the video occlusion graph on the smart television, the smart television inquires the playing progress of the video data, and removes the video occlusion graph according to the first callback message when the playing progress is determined to be changed, so that the video occlusion graph can be hidden only when the playing progress is determined to be changed after the video app of the smart television receives the first callback message, and the problem that the video occlusion graph is hidden immediately when the first callback message is received is avoided.
Moreover, the intelligent television compares the playing time with a preset threshold value after judging whether the playing progress changes, so that the accuracy of a judgment result of whether the playing progress changes is ensured. And the smart television judges whether the playing progress changes or not through the smart television, so that the method for controlling the video occlusion map on the smart television has an optimized space, and the user experience is improved.
