Problems solved by technology
[0002] During streaming media playback, some applications (such as: YouTube) require the player to obtain the current playback time (current position) quickly and accurately, but due to the limitation of calling overhead of the local player and related interfaces, the local player returns to the upper application There is a certain offset between the current playback time and the actual playback time, which makes the current playback time obtained by the upper application inaccurate
Especially when the network environment is poor, the player frequently buffers, and the current playback time obtained by the upper application is even more inaccurate
[0003] In the existing solutions, some smart TV manufacturers will calculate the offset of the current playback time by establishing a timer. Although this solution can compensate for the time offset problem to a certain extent, setting the timer will increase the system's operating time. Overhead, and the time point deviation of starting the timer will also lead to a certain deviation in the calculated results

Embodiment Construction
[0021] In order to make the purpose, technical solution and advantages of the application clearer, the application will be further described in detail below in conjunction with the accompanying drawings. The specific operation methods in the method embodiments can also be applied to the device embodiments or system embodiments.
[0022] During streaming media playback, some applications (such as: YouTube) require the player to obtain the current playback time quickly and accurately. For example, in the YouTube 2019 certification process, there is a test case used to test the accuracy of the current playback time (current time) obtained from the docking layer. This certification requires that the current playback time obtained from the docking layer and the actual playback time of the video itself The gap between the current playback time of is less than 32ms.

The embodiment of the invention relates to the technical field of streaming media playing, in particular to a method and a device for acquiring streaming media playing duration, which are used for improving the accuracy of acquiring the streaming media playing duration. The method comprises steps of obtaining the updated first playing duration of the player at the first system time; wherein the first playing duration is the playing duration of the streaming media updated by the player at the second system time, and the second system time is less than the first system time; determining a streaming media playing state of the player in a first time period, wherein the first time period is a time interval between second system time and first system time; and then, determining the actual playing duration of the streaming media in the first system time according to the first playing duration and the streaming media playing state of the player in the first time period. Therefore, the accuracyof obtaining the actual playing duration can be improved.

technical field [0001] The embodiment of the present application relates to the technical field of streaming media playback, and in particular to a method and device for acquiring streaming media playback duration. Background technique [0002] During streaming media playback, some applications (such as: YouTube) require the player to obtain the current playback time (current position) quickly and accurately, but due to the limitation of calling overhead of the local player and related interfaces, the local player returns to the upper application There is a certain offset between the current playback time of and the actual playback time, which makes the current playback time obtained by the upper-layer application inaccurate. Especially when the network environment is poor, the player frequently buffers, and the current playback time obtained by the upper-layer application is even more inaccurate.
