Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the screen-throwing scene, the mobile control terminal can throw the screen-throwing video into the screen-throwing terminal for playing. At present, when the video is played in a screen throwing mode, two videos can be played after being spliced in a code stream splicing mode, for example, an advertisement video and a television video are spliced and then the screen throwing playing is performed, but the mode is limited by a DLNA (DIGITAL LIVING NETWORKALLIANCE) throwing mode, and specifically, a DLNA third-party player can only play video streams and cannot distinguish specific contents in the videos, and further cannot respond to a mobile control end, such as a user operating a remote controller to perform click interaction, so that user experience is poor. If the played content is an advertisement, the screen throwing terminal cannot perform click-skip operation and other operations, so that the advertisement content can only be watched, the click-skip operation cannot be performed, and the advertisement effect is poor.
Further, the inventor finds that when video delivery is performed, a link corresponding to the video can be obtained, then an encoded picture corresponding to the link is added to the video in real time, and further a user can browse specific two-dimensional code contents, such as advertisement specific contents, through a mode of scanning codes, such as two-dimensional codes, in real time, thereby improving advertisement delivery effect and further improving possibility of advertisement conversion. Meanwhile, because the coded pictures added into the video are corresponding to real-time effective links, compared with a mode of pressing in the pre-generated coded pictures, the coded pictures can be ensured to be the latest effective pictures, and therefore, a user can obtain corresponding content by scanning the coded pictures.
Specifically, the invention provides a video processing method and a related device, wherein video delivery equipment receives a screen-casting request sent by a mobile terminal, the screen-casting 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 material production equipment, so as to generate a third target code stream and identification numbers of the third target code stream, the third target code stream is obtained by pressing coded pictures corresponding to the link into the second target code stream, the link can be accessed in a mode of scanning the coded pictures, the identification numbers of the third target code stream are sent to the mobile terminal, so that screen-casting playing is performed on a fourth target code stream, the fourth target code stream is obtained by sending the first target code stream and the identification numbers of the third target code stream to the video delivery equipment, and the third target code stream are sent to the cloud system by the mobile terminal, and the cloud system is spliced with the cloud system identification numbers corresponding to the third target video stream. In the invention, the fourth target code stream played by 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 the user can watch the specific content of the link by 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 equipment receives a screen throwing request sent by the mobile terminal.
Specifically, the video delivery device may be a device with a media video delivery system, and when a user views a video in a mobile terminal mobile phone software app of a media, if the user wants to perform screen projection, the screen projection function is started. At this time, the screen projection module of the mobile terminal app initiates a screen projection request to the video projection device, where the screen projection request includes a code stream of the video watched by the user, and in this embodiment, the code stream is referred to as a first target code stream. The screen projection module refers to a functional module of the mobile terminal, which is responsible for projecting a video played on the mobile terminal to other terminal playing (such as 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 different code stream from the first target code stream, for example, may be an advertisement code stream.
In practical application, the screen throwing 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 corresponding relationship may be preconfigured and configured in the video throwing device. The specific corresponding relation can be a code stream determining rule, the code stream determining rule can be a releasing strategy and the like, and the releasing strategy can be determined based on the modes of regional characteristics, 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 applications, the code stream determining rule may be preset, for example, the code stream determining rule may be a second target code stream corresponding to a first target code stream in the screen-throwing request in advance, or a second target code stream corresponding to different code stream segments in the first target code stream in advance, or a second target code stream corresponding to a date of sending the screen-throwing request, and the specific code stream determining rule may be determined according to the situation.
Taking a certain TV play as an example, the second target code stream may be an advertisement code stream to be played, which is set when the TV play is played, for example, TV play A, and the corresponding advertisement code stream is an 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 that a configurator of the second target code stream, such as an advertiser, generates an 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, the initial link cannot be identified if the initial link exceeds the maximum length set by the url link, for example, if the initial link exceeds the maximum length of the url link that the device can scan, or if the initial link is longer, the content of the initial link is more, the generated two-dimensional code is also denser, if the screen of the scanning device is smaller, the situation that the initial link cannot be scanned successfully occurs, and user experience is reduced. Thus, in order to enable the device to successfully scan the initial link, and to improve the user experience, it needs to be short-chained to facilitate recognition.
In practical application, a length threshold may be set according to the length of url links that can be scanned by the device and user experience, and if the length of the initial link exceeds the length threshold, the initial link is adjusted to be short-chain.
The specific adjustment process is as follows:
the length of the initial link is adjusted to adjust the initial link to be short-chain, namely, the initial link is changed to be short-chain, so that the link is obtained.
S13, the video delivery device 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 device.
The link may be a two-dimensional code link when in specific implementation.
Specifically, the video delivering device may call a real-time interface of the material production device, so as 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.
S14, the material production equipment generates a third target code stream and an identification number of the third target code stream.
The third target code stream is obtained by pressing the coded pictures corresponding to the links into the second target code stream, and the final display effect is that the coded pictures are in the second target code stream.
Wherein the link is accessible by scanning the encoded picture. The coding picture can be a two-dimensional code picture, and a user can acquire the specific content of the 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 mounted with a media material producing service system. The material producing apparatus may generate not only the third target code stream but also an identification number of the third target code stream, and the identification may be an identification of the code stream, that is, an id, 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:
s31, generating an encoded picture corresponding to the link.
Specifically, after receiving the link, the media material production service system generates a coded picture corresponding to the link.
S32, setting the coded picture as a watermark at a designated position in the second target code stream to obtain a third target code stream.
The designated position in the scheme may be preset, for example, the lower right corner of the second target code stream, and if the setting in the lower right corner does not affect the content display of the second target code stream, the encoded picture may be set in the lower right corner. In addition, the device can be arranged at other positions, and the device is specifically set according to actual conditions.
And in the obtained third target code stream, the second target code stream and the watermark are displayed at the same time, and the user scans the watermark of the coded picture (such as a two-dimensional code picture) to access the specific information of the two-dimensional code.
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 the identification number determination rule of the third target code stream.
The identification number determining rule, for example, when the identification numbers are digital, can be distributed in order from small to large, for example, the used maximum identification number can be added by one to be the identification number of the third target code stream. In addition, the allocation may be performed in the order of the identification numbers from the large to the small, and the specific determination rule may be set according to the actual situation.
After the 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 to a server satisfying a preset storage condition.
The server may be a CDN server or other server. When the CDN server is selected, preset storage conditions can be configured according to practical application, for example, the CDN server which is closer to the material production equipment can be selected, so that the transmission distance is reduced. Or CDN servers with smaller distance and larger residual memory, so as to reduce transmission distance and ensure enough memory 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 determining the id of the identification number of the third target code stream and storing the third target code stream and the identification number of the third target code stream to a server meeting a preset storage condition, the identification number of the third target code stream may be sent to the video delivery device.
S16, the video delivery device sends the identification number of the third target code stream to the mobile terminal so as to carry out screen-casting playing on the fourth target code stream.
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 splicing the third target code streams 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 third target code streams corresponding to the identification numbers of the first target code stream and the third target code stream to obtain a fourth target code stream.
When splicing is performed, the playlist list in m3u8 format of the first target code stream and the playlist list in m3u8 format of the third target code stream can be combined, and then splicing can be achieved.
And finally returning a fourth target code stream to a screen projection module of the mobile terminal app by the video cloud service system, and performing screen projection playing on the acquired code stream by the screen projection module. When the screen is 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 object code stream, the second object code stream, the third object code stream, and the fourth object code stream may be video streams of the DLNA protocol.
