Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are some embodiments of the present disclosure, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments in this disclosure without inventive faculty, are intended to be within the scope of this disclosure.
In addition, the term "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
Fig. 1 shows a flowchart of a method of detecting video playback according to an embodiment of the present disclosure. The method comprises the following steps:
s110, acquiring the real-time frame rate of the video.
In some embodiments, the temporal node presentationTimes that render each frame may be obtained through an underlying callback interface (e.g., onFrameRendered).
Further, the real-time frame rate of the video is determined by the difference between two adjacent frame time nodes.
Specifically, the difference between the time node of two adjacent frames is obtained by dividing the time difference by a preset time threshold (for example, 1s, namely 100000 us), and the real-time frame rate (int delta) of the current video is obtained by calculating. That is, int delta= (int) (1000000/(presentationTimeUs-mlastrendedredtimeus)).
S120, determining the current frame rate of the video based on the real-time frame rate.
In some embodiments, the final current frame rate of the video is calculated by means of two updates:
updating for the first time: an initial current frame rate is obtained, and a first current frame rate is determined based on the initial current frame rate and the real-time frame rate. That is, the first current frame rate is determined based on the largest value of the initial current frame rate and the real-time frame rate. And taking the maximum value of the initial current frame rate and the real-time frame rate to update for the first time, and determining the first current frame rate. For example, after video playing, the initial current frame rate is 0 (the frame rate of the first frame is 0), and then the value of the initial current frame rate is the real-time frame rate, that is, the value of the first current frame rate is the real-time frame rate.
Second update: comparing the first current frame rate obtained by the first updating with a preset maximum frame rate, and taking the minimum value of the two values as the final current frame rate. The preset maximum frame rate may be set according to the actual application scenario, for example, set to 25.
It should be noted that, with the playing of the video, the final current frame rate obtained by the second update may be used as the initial current frame rate in the next cycle. That is, the initial current frame rate of the first frame is 0, and the initial current frame rate of the non-first frame can be obtained by the above-described update method.
And S130, updating the value for marking the signal quality of the video based on the real-time frame rate and the current frame rate, and if the updated value meets the preset condition, sending a message comprising a conversion playing path to an application layer so that the application layer can respond to the message comprising the conversion playing path to switch the playing path.
In some embodiments, before updating the value for annotating the signal quality of the video based on the real-time frame rate and the current frame rate, further comprising:
and determining whether the current video is normally played, and if so, updating the value for marking the signal quality of the video based on the real-time frame rate and the current frame rate.
Specifically, whether the current video is played normally can be determined through the first frame of the video, for example, whether the video is played normally is determined through a true (normal) and false (abnormal) identifier set in the system in advance, if the first frame of the video is played normally, the true is the false, otherwise, the false is the true.
In some embodiments, updating the value used to annotate the signal quality of the video based on the real-time frame rate and the current frame rate includes:
if the real-time frame rate is smaller than the product of the current frame rate and a signal quality threshold value, adding 1 to a value for marking the signal quality of the video; the signal quality threshold is preferably 3/4. That is, if the real-time frame rate is less than 3/4 of the current frame rate, a value (pore count) for marking the signal quality of the video is added by 1 (pore count+1).
Further, when the value of the pore count meets a preset condition, a message including a conversion playing path is sent to an application layer, so that the application layer can switch the playing path in response to the message including the conversion playing path.
Specifically, when the value of the poorCount reaches the minimum threshold value of the trigger message (meets the preset condition), a message (notafyignalquality) for identifying the current signal quality difference is sent to a frame rate listener (FrameRateListener) preset in the player, the listener is used for continuously listening to the frame rate (onFrameRate), if the listener listens to the message notafyignalquality, a message for switching the playing path is sent to an upper layer application (apk), and the message can be a weak signal message or other customized message, so that the application layer can switch the playing path in response to the message.
According to the embodiment of the disclosure, the following technical effects are achieved:
the method comprises the steps that data are acquired from a bottom layer, video rendering frames are processed through a middle layer, the playing quality of a current video is determined, when the playing quality is poor, a message for converting a playing channel is sent to an upper layer application, so that the upper layer application can conveniently respond to the message comprising the converting playing channel, the playing channel is switched, automatic switching of the playing channel can be carried out under a scene with poor video playing quality, for example, the playing channel of a DVB program is switched to an OTT program, and the viewing experience of a user is greatly improved.
