Description
Technical Field
The invention relates to the technical field of video display, in particular to a method for asynchronous video loading and overtime monitoring.
Background
In the video presentation interface in the prior IOS, when a form is used as a frame and videos and characters are presented in sequence in the form, the video loading needs to occupy resources and has high cost, so that the form cannot be rolled in the loading process, and a user can feel that the video is blocked and unsmooth when using the video presentation interface, thereby affecting the use experience. For example:
when a user clicks one video in the form, the video is loaded (cached) so as to play the video to the user, but in the loading process, the user hopes to scroll the operation form so as to view other videos, at the moment, the loading and the scrolling cannot be synchronously performed, the table scrolling operation of the user is not responded, and the user experience is poor.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a method for asynchronously loading and monitoring overtime of a video, which adopts an asynchronous operation mode to sequentially present videos and characters in a table, can timely respond to the operation of a user, has no influence on video playing, has no influence on video loading by the operation of the user, and has better user experience.
In order to achieve the above purposes, the technical scheme adopted by the invention is as follows:
a method for asynchronous loading and timeout monitoring of video is characterized by comprising the following steps:
creating an AVURLAsset class for use in responding to calls to video asynchronous load operations,
the playing address of the current video is saved,
asynchronously loading Asset tracks data, after the loading is finished, modifying the current video state to be the loading completion,
reacquires the playing address of the current video, judges whether the playing address is consistent with the previously stored playing address,
if the video is inconsistent with the loading completion video, the current video is changed into a new video, at the moment, the playing of the video with the loading completion state is stopped,
if the video is consistent with the video, the video is not changed at present, at this time, the state judgment of Asset tracks is further carried out,
if the state judgment finds an error, the broadcast is played for error processing,
if the state judges that there is no error, an AVPlayerItem object is created, and the subsequent playing process is carried out.
On the basis of the technical scheme, when a user clicks a certain video to request playing, the AVURLAsset class is created,
and taking the video clicked by the user as the current video.
On the basis of the technical scheme, the video is loaded in the table for displaying.
On the basis of the technical scheme, the AVURLAsset class is inherited from the AVasset of the abstract class.
On the basis of the technical scheme, when Asset tracks data are asynchronously loaded, the operation of a user is preferentially responded,
including but not limited to touch screen operations.
On the basis of the technical scheme, the touch screen operation is particularly scroll touch screen operation on the form.
On the basis of the technical scheme, if the video in the loaded state is inconsistent, the playing of the video in the loaded state is stopped, then asynchronous Asset loading tracks data operation is carried out again aiming at the playing address of the current video, after the loading is finished, the state of the current video is modified to be loaded, and then the judgment of the consistency of the playing address is repeated.
On the basis of the technical scheme, after the playing address of the current video is stored, a time delay device is set, the time delay is at least 15-30 seconds, after the time delay is finished, whether the state of the current video is the loading completion or not is judged,
if the state is not load complete:
ending asynchronous loading Asset's tracks data,
and switching to playing and error reporting processing.
The method for video asynchronous loading and overtime monitoring adopts an asynchronous operation mode, sequentially presents videos and characters in the table, can timely respond to the operation of a user, has no influence on video playing, is not influenced by the operation of the user, and has better user experience.
Drawings
The invention has the following drawings:
FIG. 1 is a flow chart of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the method for asynchronous loading and timeout monitoring of video according to the present invention includes the following steps:
creating an AVURLAsset class for use in responding to calls to video asynchronous load operations,
the playing address of the current video is saved,
asynchronously loading Asset's tracks data, after loading is completed, modifying the current video state to be loading completed based on the principle that if Asset is wanted to be played, the tracks attribute of Asset should be loaded,
reacquires the playing address of the current video, judges whether the playing address is consistent with the previously stored playing address,
if the video is inconsistent with the loading completion video, the current video is changed into a new video, at the moment, the playing of the video with the loading completion state is stopped,
if the video is consistent with the video, the video is not changed at present, at this time, the state judgment of Asset tracks is further carried out,
if the state judgment finds an error, the broadcast is played for error processing,
if the state judges that there is no error, an AVPlayerItem object is created, and the subsequent playing process is carried out.
On the basis of the technical scheme, when a user clicks a certain video to request playing, the AVURLAsset class is created,
and taking the video clicked by the user as the current video.
On the basis of the technical scheme, the video is loaded in the table for displaying.
On the basis of the technical scheme, the AVURLAsset class is inherited from the AVasset of the abstract class.
On the basis of the technical scheme, when Asset tracks data are asynchronously loaded, the operation of a user is preferentially responded,
including but not limited to touch screen operations.
On the basis of the technical scheme, the touch screen operation is particularly scroll touch screen operation on the form.
On the basis of the technical scheme, the playing address of the current video is obtained again, if the playing address is different from the previously stored playing address, the user clicks a certain video again to request playing, and the previously-performed loading processing is not the video which is requested to be played by the user newly, so that the playing of the video in the loaded state is stopped.
On the basis of the technical scheme, if the video in the loaded state is inconsistent, the playing of the video in the loaded state is stopped, then asynchronous Asset loading tracks data operation is carried out again aiming at the playing address of the current video, after the loading is finished, the state of the current video is modified to be loaded, and then the judgment of the consistency of the playing address is repeated.
On the basis of the technical scheme, after the playing address of the current video is stored, a time delay device is set, the time delay is at least 15-30 seconds, after the time delay is finished, whether the state of the current video is the loading completion or not is judged,
if the state is not load complete:
ending asynchronous loading Asset's tracks data,
and switching to playing and error reporting processing.
Those not described in detail in this specification are within the skill of the art.
