Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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.
Example one
The embodiment of the invention provides a video switching method. The video switching method is used for the mobile terminal. The mobile terminal may be, but is not limited to, a mobile phone, a tablet computer, MP3/MP4, a smart watch, a smart bracelet, a Personal Digital Assistant (PDA), a vehicle-mounted computer, and the like. The system of the mobile terminal is an IOS system or an android system. Fig. 1 is a flowchart of a video switching method according to a first embodiment of the present invention. The video switching method comprises the following steps:
step 101: metadata is inserted in at least one transport stream data of the first video.
Preferably, the video playing of the method of the embodiment of the present invention may be based on a protocol of hls (http Live streaming). The HLS can realize live broadcast and on-demand of streaming media and provide a video live broadcast and on-demand scheme for the mobile terminal. Based on HLS playing, the video is divided into small data segments and organized in a playlistic mode, and the playing process is to acquire the data segments from a server side through HTTP. The data file encapsulation formats supported by HLS are mainly MPEG transport streams (MPEG-TS, TS).
When packaging video, the metadata is kept consistent with the video stream and the audio stream as an independent data stream, namely, the time axis is kept synchronous. Preferably, the metadata is encapsulated into the transport stream data in the ID3 data format. The data in the ID3 data format is readable by a video player. The type of metadata is a plain text data type in the ID3 data format. The plain text data is typically a string of characters in a fixed format. The specific form of the fixed format is customizable. The fixed format is adopted, so that the metadata can be conveniently identified by the method of the embodiment, and the difficulty that different metadata adopt different formats to increase identification is avoided. The metadata includes instruction information, and specifically, a dedicated field may be used in the fixed-format string to describe the instruction information. The instruction information is used for prompting the next action when the first video is played to the time point.
Specifically, the instruction information includes: after the first video is played, the playing of the first video is interrupted, or the playing of the second video is resumed, preferably, the step 101 specifically includes:
metadata is inserted in the last or non-beginning transport stream data of the first video.
Step 102: in the process that the first video player plays the first video, if the metadata is called back at any moment, the second video player is switched to play the second video.
The first video, the second video may be an advertisement, a feature, or the like. Thus, the video switch may be ad to ad, ad to feature, feature to feature.
Since the instruction information contained in the metadata includes: after the first video is played, the playing of the first video is interrupted, or the playing of the second video is resumed, preferably, the step 102 specifically includes:
in the process of playing the first video by the first video player, if the metadata is obtained by calling back at the moment when the first video is played or at any moment of playing the first video, which is not the beginning or the end, the corresponding second video player is switched to play or the playing of the second video is resumed.
Specifically, taking the IOS system as an example, the first video player and the second video player may employ an avplayer. The player is a player carried by the IOS system of the mobile terminal. The player may support point-in-time based metadata presentation. A metadata callback is registered by the avplayer, and when the avplayer encounters ID3 data in metadata during playing, the avplayer is informed of the ID3 data through the callback interface. Therefore, this feature of the avplayer can implement a callback mechanism. The callback mechanism does not depend on the playing progress, but triggers the switching action of the avplayer through a callback event, and particularly, the playing scene is interrupted. Therefore, by inserting the metadata into the transport stream data in step 101, different switching operations can be triggered according to the instruction information included in the metadata after the metadata is obtained by callback in step 102.
To sum up, in the video switching method according to the first embodiment of the present invention, metadata including instruction information is inserted into transport stream data of a video, and when the metadata is obtained by callback in a video playing process, a video can be switched according to the instruction information in the metadata, and since the metadata is inserted into a specific transport stream data, the video can be accurately switched at a specific time without increasing precision of obtaining a playing progress, and a flow of inserting the metadata is simple, and a load or complexity of a system is not increased, so that switching between the video and the video is more accurate and flexible, resources are less occupied, and user experience is improved.
Example two
The second embodiment of the invention provides a video switching method. The video switching method is used for the mobile terminal. The mobile terminal may be, but is not limited to, a mobile phone, a tablet computer, MP3/MP4, a smart watch, a smart bracelet, a Personal Digital Assistant (PDA), a vehicle-mounted computer, and the like. The system of the mobile terminal is an IOS system or an android system. The video switching method is suitable for scenes in which the instruction information is that the first video is played completely. Fig. 2 is a flowchart of a video switching method according to a second embodiment of the present invention. The video switching method comprises the following specific steps:
step 201: metadata is inserted in the last transport stream data of the first video.
For example, if the first video is an advertisement, metadata is inserted into the last transport stream data of the advertisement video. The instruction information contained in the metadata is that the advertisement is played completely.
Step 202: in the process of playing the first video by the first video player, if the metadata is obtained by calling back at the moment when the first video is played, switching to the corresponding second video player to play the second video according to a preset video playing sequence or an instant received playing instruction.
For example, if the second video is a feature film, after the advertisement serving as the first video is played, the metadata including the instruction information "advertisement playing completed" is called back, and the second video player is switched to play the feature film. In addition, the second video may also be a new advertisement.
The predetermined playing sequence is generally the sequence set by the video provider. The instant received playing command is generally an instant command input by a user. Wherein, the meaning that the instant receiving playing instruction indicates is: and when the first video is played and the metadata is called back, the playing instruction is received immediately. Therefore, switching to the corresponding second video player to play the second video representation according to the instant received playing instruction means: when the first video is played and the metadata is called back, and the second video needs to be switched, if the playing instruction is received immediately, the video is not played according to the preset video playing sequence, but the second video indicated by the instruction is played. For example, a plurality of advertisement videos are played before a feature film is played, and on a page where a current advertisement is played, members of some video websites can make a player skip the following advertisement by clicking the skip advertisement, so as to directly play the feature film.
In summary, the instruction information in the video switching method according to the second embodiment of the present invention is that the first video is completely played, so that after the first video is completely played, the metadata including the instruction information is obtained through callback, and the video switching method can be accurately and flexibly switched to the second video after the first video is completely played.
EXAMPLE III
The third embodiment of the invention provides a video switching method. The video switching method is used for the mobile terminal. The mobile terminal may be, but is not limited to, a mobile phone, a tablet computer, MP3/MP4, a smart watch, a smart bracelet, a Personal Digital Assistant (PDA), a vehicle-mounted computer, and the like. The system of the mobile terminal is an IOS system or an android system. The video switching method is suitable for scenes with instruction information of interruption of first video playing. Fig. 3 is a flowchart of a video switching method according to a third embodiment of the present invention. The video switching method comprises the following specific steps:
step 301: metadata is inserted in non-head-to-tail located transport stream data of the first video.
For example, the first video is a feature film. The instruction information contained in the metadata is a feature play interruption. The transport stream data is arranged according to a time axis of the first video. Therefore, by inserting the metadata in any transport stream data located not at the beginning or end, the effect of interrupting the playing of the first video at a specific point in time can be achieved.
Step 302: in the process of playing the first video by the first video player, if the metadata is obtained by calling back at any time of playing the first video, the corresponding second video player is switched to play the second video according to a preset video playing sequence or an instant received playing instruction.
For example, the second video is an advertisement. When the feature film serving as the first video is played to a specific moment which is not head and tail, the metadata containing the instruction information of 'feature film playing interruption' is called back, and then the second video player is switched to play the advertisement.
As in the second embodiment, the preset playing sequence is generally the sequence set by the video provider, and the instant received playing command is generally an instant command input by the user, for example, after the feature film playing is interrupted, a plurality of advertisement videos are generally inserted, and on the page where the current advertisement is played, members of some video websites can make the player skip the following advertisement by clicking the skip advertisement, so as to directly play the feature film.
To sum up, the instruction information in the video switching method according to the third embodiment of the present invention is the interruption of the playing of the first video, so that in the playing process of the first video, the metadata including the instruction information is obtained by calling back at any time other than the beginning and the end of the first video, and the video switching method can accurately and flexibly switch to the second video in the playing process of the first video, and is particularly suitable for being applied to a scene in which an advertisement is inserted in a feature film.
Example four
The fourth embodiment of the invention provides a video switching method. The video switching method is used for the mobile terminal. The mobile terminal may be, but is not limited to, a mobile phone, a tablet computer, MP3/MP4, a smart watch, a smart bracelet, a Personal Digital Assistant (PDA), a vehicle-mounted computer, and the like. The system of the mobile terminal is an IOS system or an android system. The video switching method is suitable for the scene of the instruction information for resuming playing the second video. Fig. 4 is a flowchart of a video switching method according to a fourth embodiment of the present invention. The video switching method comprises the following specific steps:
step 401: metadata is inserted in the last transport stream data of the first video.
For example, if the first video is an advertisement and the second video is a feature, metadata is inserted into the last transport stream data of the advertisement video. The instruction information included in the metadata is to resume playing the feature film.
Step 402: in the process of playing the first video by the first video player, if the metadata is called back at the moment when the first video is played completely, switching to the second video player and playing the second video from the moment when the second video is interrupted.
For example, if the second video is a feature film, after the advertisement serving as the first video is played, the metadata including the instruction information "resume playing the feature film" is called back, and the second video player is switched to continue playing the feature film from the time when the feature film is interrupted.
To sum up, the instruction information in the video switching method according to the fourth embodiment of the present invention is to resume playing the second video, so that after the first video is played, the metadata including the instruction information is obtained through callback, the second video can be accurately and flexibly switched to after the first video is played, and the second video is continuously played from the time when the second video is interrupted, and the method is particularly suitable for being applied to a scene where the advertisement inserted in the feature film is switched back to the feature film after the advertisement playing is finished.
