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 only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
In a screen projection scene, the mobile control terminal can project the screen projection video to the screen projection terminal for playing. At present, when screen projection playing is performed, two videos can be played after being spliced in a code stream splicing mode, for example, an advertisement video and a television play video are spliced and then screen projection playing is performed, but this mode is limited by a DLNA (DIGITAL LIVING network alliance ) playing mode, specifically, a third-party player of the DLNA can only play a video stream, cannot distinguish specific contents in the video, and further cannot respond to a mobile control terminal, for example, a user operates a remote controller to perform click interaction, so that user experience is poor. If the played content is an advertisement, the screen-casting terminal cannot perform operations such as click-to-jump and the like, so that the advertisement content can only be viewed, the click-to-jump operation cannot be performed, and the advertisement effect casting is poor.
Further, the inventor finds that a link corresponding to a video can be acquired when the video is delivered, and then a coded picture corresponding to the link is added to the video in real time, so that a user can browse specific two-dimensional code contents, such as specific contents of advertisements, by scanning the codes in real time, such as a two-dimensional code mode, thereby improving advertisement delivery effects and further improving the possibility of advertisement conversion. Meanwhile, because the coded pictures added into the video correspond to the real-time effective links, compared with a mode of pressing in the pre-generated coded pictures, the method can ensure that the coded pictures are the latest effective pictures, thereby ensuring that a user can acquire corresponding contents by scanning the coded pictures.
Specifically, the invention provides a video processing method and a related device, wherein a video delivery device receives a screen delivery request sent by a mobile terminal, the screen delivery request comprises a first target code stream, a second target code stream corresponding to the first target code stream and a link corresponding to the second target code stream are determined and sent to a material production device so as to generate a third target code stream and an identification number of the third target code stream, the identification number of the third target code stream is sent to the video delivery device, the third target code stream is obtained by pressing a coded picture corresponding to the link into the second target code stream, the link can be accessed by scanning the coded picture, the identification number of the third target code stream is sent to the mobile terminal so as to perform screen delivery playing on a fourth target code stream, the fourth target code stream is obtained by splicing the first target code stream and a third target code stream corresponding to the identification number of the third target code stream for the mobile terminal, and the video cloud service system performs splicing on the first target code stream and the third target code stream corresponding to the identification number of the third target code stream. In the invention, the fourth target code stream played by the screen projection is obtained by splicing the first target code stream and the third target code stream obtained by pressing the coded picture corresponding to the link into the second target code stream, and a user can watch the specific content of the link in a mode of scanning the coded picture, so that the interactivity of the user is improved, and the user experience is further improved.
Referring to fig. 1, an embodiment of the present invention provides a video processing method, which may include:
s11, the video delivery device receives a screen delivery request sent by the mobile terminal.
Specifically, the video delivery device may be a device equipped with a media video delivery system, and when a user watches a video in a mobile phone software app of a media, if the user wants to perform screen delivery, the screen delivery function is started. At this time, the screen projection module of the mobile app may initiate a screen projection request to the video projection device, where the screen projection request includes a code stream of a video watched by a user, and is referred to as a first target code stream in this embodiment. The screen projection module refers to a functional module of the mobile terminal, which is responsible for projecting a screen, and is used for projecting a video played on the mobile terminal to other terminals for playing (for example, a television TV or other OTT (Over-the-top media services, over-the-top service or Over-the-top content service) devices).
S12, the video delivery device determines a second target code stream corresponding to the first target code stream and a link corresponding to the second target code stream.
In this embodiment, the second target code stream may be a code stream different from the first target code stream, such as an advertisement code stream.
In practical application, the screen-casting request includes a first target code stream, the second target code stream may be a code stream corresponding to the first target code stream, and the specific correspondence may be configured in advance and configured in the video casting device. The specific corresponding relation may be a code stream determination rule, the code stream determination rule may be a release policy, and the release policy may be determined based on a region characteristic, a user preference, and the like.
Specifically, referring to fig. 2, step S12 may include:
s21, determining a second target code stream corresponding to the first target code stream based on a preset code stream determination rule.
In practical application, the code stream determination rule may be preset, for example, the code stream determination rule may be a second target code stream corresponding to a first target code stream in the screen projection request in advance, or a second target code stream corresponding to a different code stream segment in the first target code stream in advance, or a second target code stream corresponding to a date when the screen projection request is sent, and the specific code stream determination rule may be determined according to a situation.
Taking the first target code stream as an example of a certain tv play, the second target code stream may be an advertisement code stream to be played, which is set when the tv play is played, such as tv play a, and the corresponding advertisement code stream is advertisement code stream B, which is only exemplary and not limited in particular.
S22, determining an initial link corresponding to the second target code stream, and performing length adjustment operation on the initial link to obtain a link.
Specifically, for the second target code stream, an initial link of the second target code stream is determined (this step may be a configurator of the second target code stream, for example, an advertiser generates the initial link of the second target code stream, and then the video delivery device directly obtains the initial link.
In this embodiment, if the initial link is longer and exceeds the maximum length set by the url link, the initial link may not be identified, for example, the maximum length of the url link that can be scanned by the device is exceeded, or if the initial link is longer, the content of the url link is more, the generated two-dimensional codes are also denser, and if the screen of the scanning device is smaller, the initial link may not be successfully scanned, so that the user experience is reduced. Therefore, in order to enable the device to successfully scan the initial link and improve the user experience, it needs to be changed into a short chain for easy recognition.
In practical application, a length threshold may be set according to the length of the url link that can be scanned by the device and the user experience, and if the length of the initial link exceeds the length threshold, the initial link is adjusted to be a short link.
The specific adjusting process is as follows:
the length of the initial link is adjusted to adjust the initial link to be short, i.e. the initial link is changed to be short, thereby obtaining the link.
And S13, the video delivery equipment sends a second target code stream corresponding to the first target code stream and a link corresponding to the second target code stream to the material production equipment.
When the link is implemented specifically, the link may be a two-dimensional code link.
Specifically, the video delivery device may call a real-time interface of the material production device to send a second target code stream corresponding to the first target code stream and a link corresponding to the second target code stream to the material production device.
And S14, generating a third target code stream and an identification number of the third target code stream by the material production equipment.
And the third target code stream is obtained by pressing the coded picture corresponding to the link into the second target code stream, and the final display effect is that the coded picture exists in the second target code stream.
Wherein the link is accessible by scanning the encoded picture. The coded picture can be a two-dimensional code picture, and a user can acquire specific content of a two-dimensional code link corresponding to the two-dimensional code picture in a mode of scanning the two-dimensional code picture.
The material producing apparatus may be an apparatus in which a media material production service system is installed. The material production device may generate not only the third target code stream but also an identification number of the third target code stream, where the identification may be an identity, i.e. id, of the code stream, for example, 009 is used as the identification number of the third target code stream, or a video name of the third target code stream is used as the identification number of the third target code stream. How the specific identification number is set can be configured according to actual conditions.
Specifically, referring to fig. 3, step S14 may include:
and S31, generating a coded picture corresponding to the link.
Specifically, after receiving the link, the media material production service system generates a coded picture corresponding to the link.
And S32, setting the coded picture as a watermark at a specified position in the second target code stream to obtain a third target code stream.
The specified position in the scheme may be preset, for example, the lower right corner of the second target code stream, and if the setting on the lower right corner does not affect the content display of the second target code stream, the encoding picture may be set on the lower right corner. In addition, the device can be arranged at other positions, and is set according to the actual situation.
In the obtained third target code stream, the second target code stream and the watermark are displayed at the same time, and the user can access the specific information of the two-dimensional code by scanning the watermark of the coded picture (such as the two-dimensional code picture).
And S33, determining the identification number of the third target code stream according to a preset identification number determination rule.
Specifically, the identification number id of the third target code stream may be determined according to an identification number determination rule of the third target code stream.
The identification number determination rule may, for example, allocate the identification numbers in order from small to large when the identification numbers are numbers, and for example, add one to the largest identification number that has been used to obtain the identification number of the third target code stream. In addition, the identification numbers can be distributed in the order from large to small, and specific determination rules are set according to actual conditions.
After a third target code stream and the identification number of the third target code stream are generated, the third target code stream and the identification number of the third target code stream may be stored in a server that meets a preset storage condition.
The server may be a CDN server or other server. When the CDN server is selected, the preset storage condition may be configured according to actual application, and for example, a CDN server closer to the material production device may be selected to reduce the transmission distance. Or the CDN server is close in distance and large in residual memory, so that the transmission distance is reduced and sufficient memory storage is ensured as much as possible.
And S15, the material production equipment sends the identification number of the third target code stream to the video delivery equipment.
Specifically, after the identification number id of the third target code stream is determined and the third target code stream and the identification number of the third target code stream are stored in the server meeting the preset storage condition, the identification number of the third target code stream may be sent to the video delivery device.
And S16, the video delivery equipment sends the identification number of the third target code stream to the mobile terminal so as to perform screen delivery playing on a fourth target code stream.
The fourth target code stream is obtained by sending, by the mobile terminal, the identification numbers of the first target code stream and the third target code stream to a video cloud service system, and the video cloud service system splices the third target code stream corresponding to the identification numbers of the first target code stream and the third target code stream.
Specifically, the video delivery device sends the identification number of the third target code stream to the mobile terminal at the front end.
Then, the mobile terminal sends the identification numbers of the first target code stream and the third target code stream to a video cloud service system, and the video cloud service system obtains the third target code stream from a CDN server based on the identification number of the third target code stream, and splices the first target code stream and the third target code stream corresponding to the identification number of the third target code stream to obtain a fourth target code stream.
When splicing is performed, the playlist list in the m3u8 format of the first target code stream and the playlist list in the m3u8 format of the third target code stream may be merged, so that splicing can be achieved.
And finally, the video cloud service system returns a fourth target code stream to a screen projection module of the mobile terminal app, and the screen projection module performs screen projection playing on the acquired code stream. When the screen is projected and played, the screen can be projected to a screen projection terminal, and the screen projection terminal can be a television TV or other OTT equipment.
It should be noted that, in the present invention, the first target code stream, the second target code stream, the third target code stream, and the fourth target code stream may be video streams of a DLNA protocol.
In this embodiment, a video delivery device receives a screen delivery request sent by a mobile terminal, where the screen delivery request includes a first target code stream, a second target code stream corresponding to the first target code stream and a link corresponding to the second target code stream are determined and sent to a material production device to generate a third target code stream and an identification number of the third target code stream, and the identification number of the third target code stream is sent to the video delivery device, where the third target code stream is obtained by pressing a coded picture corresponding to the link into the second target code stream, the link is accessible by scanning the coded picture, and the identification number of the third target code stream is sent to the mobile terminal to perform screen delivery playing on a fourth target code stream, where the fourth target code stream is obtained by the mobile terminal sending the identification numbers of the first target code stream and the third target code stream to a video cloud service system, and the video cloud service system performs screen delivery on the third target code stream corresponding to a splicing number of the first target code stream and the third target code stream. In the invention, the fourth target code stream played by the screen projection is obtained by splicing the first target code stream and the third target code stream obtained by pressing the coded picture corresponding to the link into the second target code stream, and a user can watch the specific content of the link in a mode of scanning the coded picture, so that the interactivity of the user is improved, and the user experience is further improved.
In addition, the invention realizes the combination of the screen projection video and the two-dimension code, can be applied to advertisement screen projection scenes, inserts the two-dimension code into the video advertisement content to generate the two-dimension code in real time, and realizes the landing of the two-dimension code advertisement in the screen projection scenes.
