Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The method and apparatus for detecting a video playing status provided by the embodiments of the present invention are applied to electronic devices capable of playing video, and the electronic devices include, but are not limited to, Personal computers, server computers, handheld or laptop devices, mobile devices (such as mobile phones, Personal Digital Assistants (PDAs)), portable, pocket, computer-embedded or vehicle-mounted mobile apparatuses, and the like.
As shown in fig. 2, a video playing state detection system according to an embodiment of the present invention is provided, and the video playing state detection method and apparatus according to an embodiment of the present invention are based on the detection system. The method comprises the following steps:
the decoding module 201 can be specifically realized by Codec, and completes the function of decoding the video;
the Texture map module 202, which can be specifically implemented by Texture, is used for storing a Texture map of the Codec decoding result, and updates the Texture map when the decoder obtains the decoding result of a new frame, and triggers a Texture update callback function.
The map display rendering module 203 is specifically configured to represent the location where the map is displayed and Render the map through Surface & Render;
the timer module 204 represents a timer in the detection thread, and issues a corresponding error warning when the timer expires.
The error processing module 205 may be specifically implemented by Handle, and indicates error insertion processing performed after an error is detected.
The detection of the video playing state in the embodiment of the present invention is performed when the texture mapping module 202 maps, a detection thread is added to perform state detection, the detection of picture update is performed by callback during texture refresh of the decoding result mapping, and whether the video is played incorrectly is determined by whether a timer is overtime. The detection of the playing state is completely based on the use experience of the user and based on whether the video playing is normal or not as the measuring standard of the current player state, and the analysis is not carried out according to the specific decoding problem. Although the cause of the decoding error may be different, the process of feeding back to the playback software is the same. In addition, partial decoding errors do not affect the actual viewing of the video, or some errors (e.g., lack of video stream in a file) are not effectively fed back in some decoders, resulting in errors that do not affect the results being detected and error-handled, or some errors not being detected. Therefore, the state analysis is not performed according to the decoding error, but the play state is detected according to the result of the video play.
The video playing state detection system provided by the embodiment of the invention provides a unified video playing detection method aiming at different decoder frames and different video types, and improves the detection efficiency and the practicability.
Based on the above detection system for the video playing status, an embodiment of the present invention provides a method for detecting the video playing status, and as shown in fig. 3, a schematic flow diagram of the method for detecting the video playing status according to the embodiment of the present invention includes:
step 301: and when the video playing thread is started, starting a first timer.
Specifically, when a video source (a video file or an online video stream) is opened by a playback thread, an instruction is sent to a detection thread, thereby triggering the detection thread. The detecting thread enters the load detecting state and starts an internal first timer, and the time limit of the first timer is set to T1.
Step 302: and if the map callback function is acquired within the set time of the first timer, starting a second timer.
Further, if the map callback function is not acquired within the set time of the first timer, it is determined that the video is open incorrectly.
Specifically, if the video cannot be normally opened, the playback thread does not output the decoding result to the map, and therefore, the map callback is not triggered, and therefore, if the video playback thread does not acquire the map callback function within the set time of the first timer T1, a video opening error is triggered.
Specifically, if the video is normally opened, the playing thread outputs a decoding result to the map, so as to trigger a map callback, and therefore, if the frequently playing thread acquires a map callback function within the set time of the first timer T1, the callback success message is sent to the detection thread, the detection thread enters a play detection state, the second timer T2 is started, and the time limit of the second timer is set to T2, so as not to trigger a video opening error.
For example, if the set time limit of the first timer T1 is 2s, if the playback thread does not acquire the map callback function within 2s after the video source is opened, it is determined that the video is open incorrectly. And if the playback thread acquires the map callback function 2s after the video source is opened, sending a callback success message to the detection thread, starting a second timer T2 by the detection thread, and setting the time limit of the second timer to be 0.1 s.
Step 303: and if the mapping callback function is not acquired within the set time of the second timer, determining that the video is played wrongly.
Further, if the map callback function is acquired within the set time of the second timer T2, the second timer T2 is reset.
Specifically, if the video cannot be normally played, the playing thread does not output the decoding result to the map, so that the map callback is not triggered, and therefore, if the video playing thread does not acquire the map callback function within the set time of the second timer T2, a video playing error is triggered.
Specifically, if the video is played normally, the playing thread outputs a decoding result to the map, so as to trigger a map callback, and therefore, if the video playing thread acquires a map callback function within the set time of the second timer T2, the callback success message is sent to the detection thread, the detection thread resets the second timer T2, sets the time limit of the second timer to T2, and continues to perform play detection.
For example, the set time limit of the second timer T2 is 0.1s, and after the detection thread starts the second timer T2, if the playback thread does not acquire the map callback function within 0.1s, it is determined that the video playback error occurs. And if the playing thread acquires the map callback function within 0.1s, sending a callback success message to the detection thread, resetting a second timer T2 by the detection thread, setting the time limit of the second timer to be 0.1s, and continuing to perform playing detection.
It should be noted that the timing functions of the first timer and the second timer may also be implemented by the same timer. Specifically, when the detection thread enters a loading detection state, an internal timer is started, and the time limit of the timer is set to be T1; the detecting thread enters the play detect state, resets the timer, and sets the timer to a time limit of T2. The number of specific timers is not limited herein.
It should be noted that, in the embodiment of the present invention, the video playing status may also be determined according to the decoding result of the decoder in combination with the map callback status. Specifically, when the video source is opened by the playing thread, the real-time decoding result of the decoder is acquired at the same time, and the playing state of the video is determined according to the state of the first timer or the state of the second timer and the decoding result information. The detailed reasons of video errors can be determined by analyzing the decoding result, whether the picture is updated or not is determined by callback during texture refreshing of the decoding result, namely the visual state of video playing is determined, and the video playing state can be detected more completely and accurately by combining judgment of the decoding result and the callback during texture refreshing.
In practical application, the detection result is correspondingly processed according to the current video type. If the video source is a local file, outputting format unsupported information after determining that the video is open wrongly; outputting incomplete information of the video file after determining that the video playing is wrong; if the video source is an online video stream, outputting network connection error information after determining that the video is open wrongly; and after the video playing error is determined, outputting network instability information.
The embodiment of the invention provides a method for detecting a video playing state, which comprises the steps of starting a first timer when a video playing thread is started; if the map callback function is acquired within the set time of the first timer, starting a second timer; and if the mapping callback function is not acquired within the set time of the second timer, determining that the video is played wrongly. According to the method for detecting the video playing state provided by the embodiment of the invention, the picture updating is detected through the call-back during the refreshing of the texture of the decoding result chartlet, and whether the video is played wrongly is judged through whether the timer is overtime or not. And the playing state is detected according to the video playing result, so that the detection efficiency and the practicability are improved.
An embodiment of the present invention further provides a method for detecting a video playing status, as shown in fig. 4, which is a flowchart of the method for detecting a video playing status according to the embodiment of the present invention, and the method includes:
step 401: and starting a timer when the video playing thread is started.
Specifically, when a video source (a video file or an online video stream) is opened by a playback thread, an instruction is sent to a detection thread, thereby triggering the detection thread. The detecting thread enters the load detecting state and starts an internal timer, and the timer time limit is set to T1.
Step 402: and judging whether the map callback function is acquired within the set time T1 of the timer. If yes, go to step 404, otherwise go to step 403.
Step 403: and if the timer is overtime, outputting a video opening error.
Specifically, if the video cannot be normally opened, the playback thread does not output the decoding result to the map, and therefore, the map callback is not triggered, and therefore, if the video playback thread does not acquire the map callback function within the set time T1 of the timer, a video opening error is triggered.
Step 404: the timer is reset and the time limit of the timer is set to T2 and the process continues to step 405.
Specifically, if the video is normally opened, the playing thread outputs a decoding result to the map, so as to trigger a map callback, and therefore, if the frequently playing thread acquires a map callback function within the set time of the timer T1, the callback success message is sent to the detecting thread, the detecting thread enters a playing detection state, the timer is reset, and the time limit of the timer is set to be T2.
Step 405: and judging whether the map callback function is acquired within the set time T2 of the timer. If so, go to step 404, otherwise go to step 406.
Step 406: and if the timer is overtime, outputting a video playing error.
Specifically, if the video cannot be normally played, the playing thread does not output the decoding result to the map, so that the map callback is not triggered, and therefore, if the video playing thread does not acquire the map callback function within the set time T2 of the timer, a video playing error is triggered.
Specifically, if the video is played normally, the playing thread outputs a decoding result to the map, so as to trigger a map callback, and therefore, if the video playing thread acquires a map callback function within the set time T2 of the timer, a callback success message is sent to the detection thread, the detection thread resets the timer, sets the time limit of the timer to be T2, and continues to perform play detection.
