In order to make the present application solution better understood by those skilled in the art, the following description will clearly and completely describe the technical solution in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Referring to fig. 1, the flowchart of a live time-shift playing method provided in an embodiment of the present application includes:
s101: and acquiring a current live watching time interval and a time shift request.
Currently, live content is more and more abundant, and viewers facing live broadcast are increasing. When the viewer wants to watch the part that has been missed in the current live, it is often necessary to wait for the playback to be watched after the live is finished, and in order to subtract the waiting time, live time shifting occurs.
Live time shifting is a function of playing back live content at random for the past time, so that a user can select a back-off time length to watch a missed portion at any time by, for example, dragging a progress bar of the time shifting when live broadcasting is performed in real time.
Alternatively, the current live viewable time interval may be obtained by: firstly, a current live broadcast start time node, a live broadcast stop time node and a live broadcast continuation time node can be obtained, wherein the live broadcast start time node is a live broadcast start time node, the live broadcast stop time node is a live broadcast stop time node caused by abnormal conditions such as network disconnection, weak network, incoming call, wheat cutting, APP breakdown and the like, when the normal state is restored again, the live broadcast end is automatically or the host broadcast is selected to be reconnected, and the live broadcast restoration time node is the live broadcast continuation time node; then, the current live broadcast viewable time interval may be obtained based on the above-mentioned on-air time node, off-air time node and on-air time node, for example, an on-air time list may be formed based on the above-mentioned on-air time node, off-air time node and on-air time node, where the on-air time node or on-air time node is preceding, the time interval of the off-air time node after or without the off-air time node is viewable time interval, the time interval of the off-air time node before and the on-air time node after is abnormal time interval.
For example, if the open time node is 17:00 on 1 day of 6 months, the break time node is 18:00 on 1 day of 6 months, and the continuous time node is 18:20 on 1 day of 6 months, the current time, the abnormal time and the time interval without viewable content are obtained, wherein the viewable time interval is 17:00-18:00 on 1 day of 6 months, and the current time is 18:20 on 18:00 on 1 day of 6 months.
S102: and obtaining the target playing time node based on the back-off time length carried by the time shift request and the current time information.
For example, the target playing time node may be obtained by subtracting the back-off time from the current time, for example, the current time may be obtained to be 19:00 on 1 day of 6 months based on the current time information, and the back-off time carried by the time shift request is 30 minutes, and then the target playing time node may be obtained to be 18:30 on 1 day of 6 months.
S103: and determining the time shift playing node based on the target playing time node and the viewable time interval.
As an example, if the target play time node is within the viewable time interval, determining the target play time node as a time-shifted play node; if the target playing time node is not in the viewable time interval, determining the nearest continuous playing time node after the target playing time node as the time shift playing node.
For example, the current time is 6 months 1 day 19:20; the viewable time interval is 6 months, 1 day, 17:00-18:00 and 18:20-the current time; when the rollback time is 30 minutes, the corresponding target playing time node is 18:50 on 6 months and 1 day, and in the viewable time interval, the target playing time node can be determined to be a time shift playing node on 6 months and 1 day, 18:50; when the rollback time is 70 minutes, the corresponding target playing time node is 6 months 1 days 18:10, and if the target playing time node is not in the viewable time interval, the last continuous playing time node 6 months 1 days 18:20 after the last continuous playing time node 6 months 1 days 18:10 can be determined as the time shift playing node.
S104: and starting to play the current live broadcast from the time-shifting play node.
For example, taking the time shift playing node as an example, the current live broadcast can be played from a live broadcast picture when the current live broadcast is at 6 months 1 days 18:20.
Therefore, the time shift playing node is determined based on the target playing time node and the obtained viewable time interval, and the time shift playing node can be actively switched to the continuous playing time node when the current target playing time node is not in the viewable time interval, so that the situation that video pictures cannot be played or the playing content is repeatedly played is avoided, and the viewing experience of a user is improved.
Referring to fig. 2, the flowchart of another live time-shift playing method provided in an embodiment of the present application includes:
s201: based on the WebSocket monitoring technology, the current live broadcast on-time node, the current live broadcast off-time node and the current live broadcast on-time node are obtained.
Illustratively, the current live broadcast state can be obtained based on WebSocket monitoring technology, and the live broadcast state can include but is not limited to on-air, off-air, continuous broadcast and the like; and then, based on the obtained live broadcast state, obtaining the current live broadcast on-time node, the current live broadcast off-time node and the current live broadcast on-time node through the HTTP request.
S202: and obtaining the current live broadcast viewable time interval based on the on-time node, the off-time node and the continuous-time node.
For example, the open time node, the break time node and the continuous time node acquired by WebSocket monitoring technology can be recorded to a preset open time list, so that the current live broadcast viewable time interval is obtained based on the open time list. Optionally, the above-mentioned open time list may be obtained when the live time shift function is turned on, or the above-mentioned open time list may be obtained when the current live is entered, so as to obtain a viewable time interval of the current live.
As an example, the time-to-live list may include, but is not limited to, an identification of the current live, a time node type, and the like, e.g., the time-to-live list may include an identification of the current live, e.g., a live room number, a time type of the live, and a time node, e.g., 18:00 a month 1 day, and the like. When the open time node is obtained based on the WebSocket monitoring technology, the obtained open time node of the current live broadcast can be recorded to a preset open time list, or the open time list is generated based on the obtained open time node of the current live broadcast and a preset open time list structure; when the current live broadcast breaking time node is obtained based on the WebSocket monitoring technology, the breaking time list of the recorded breaking time node can be updated based on the obtained breaking time node; when the live broadcast continuous time node is obtained based on the WebSocket monitoring technology, the recorded open time list of the open time node and the open time list of the broken time node can be updated based on the obtained continuous time node. Therefore, the current live broadcast viewable time interval can be obtained based on the current live broadcast on-time list, and specifically, the time interval of the on-time node or the continuous broadcast time node before, the time interval of the continuous broadcast time node after or the time interval of the continuous broadcast time node without the continuous broadcast time node is the viewable time interval; the time interval of the front and rear time nodes of the break-broadcasting time node is an abnormal time interval.
S203: a time shift request is obtained.
The time shift request may be information input by the user when using the time shift function, for example, may be rollback time length information corresponding to the user dragging the time shift progress bar, and the like.
S204: and obtaining the target playing time node based on the back-off time length carried by the time shift request and the current time information.
The target playout time node may be obtained by subtracting the backoff time duration from the current time, for example.
S205: judging whether the target playing time node is in a viewable time interval or not, if so, executing the step S206; if not, the step of S207 is performed.
For example, taking a viewable time interval of 6 months 1 day 17:00-17:50, 6 months 1 day 17:53-18:30, and 6 months 1 day 18:35-the current time as an example, if the target playing time node is 6 months 1 day 17:51, it may be determined that the target playing time node is not within the viewable time interval; if the target playing time node is 17:56 on 1 day of 6 months, the target playing time node can be judged to be in the viewable time interval.
S206: and determining the target playing time node as a time shift playing node, and starting to play the current live broadcast from the time shift playing node.
S207: and determining the nearest continuous playing time node after the target playing time node as a time shift playing node, and starting to play the current live broadcast from the time shift playing node.
S208: judging whether the current playing node is in a viewable time interval or not at preset time intervals, if so, executing a step S209; if not, the step of S210 is performed.
For example, the preset time interval may be set to 1 second, i.e., it is determined once every 1 second whether the current playback node is within the viewable time interval. Taking the example that the viewable time interval is 6 months 1 day 17:00:27-17:50:45, 6 months 1 day 17:53:38-18:30:42 and 6 months 1 day 18:35:52-the current time, when the current playing node is 6 months 1 day 17:50:45, the current playing node is in the viewable time interval; when the current playing node is 17:50:46 in 1 day of 6 months, the current playing node is not in the viewable time interval.
Optionally, the live time shift may include a fast forward play and/or a fast reverse play function, and when fast forward or fast reverse play the video frame after the live time shift, it may be determined in advance whether each play node is within a viewable time interval before starting playing the current live.
S209: and taking the current playing node as a time shift playing node to continuously play the current live broadcast.
S210: and taking the latest continuous playing time node after the current playing node as a time shift playing node to continuously play the current live broadcast.
Therefore, whether the current moment is in the viewable time interval can be judged in real time in the live time shift playing process, when the current moment is not in the viewable time interval, the abnormal time interval is skipped, the current live is continuously played from the continuous playing time node nearest to the current moment, the live time shift playing is always in the viewable time interval, and the situation that the played content is repeatedly or discontinuously played before after the live time shift playing is in a period of time is avoided, so that the user watching experience is improved.
