Fig. 1 is a flowchart of a video screen projection method provided by an embodiment of the present disclosure, where the embodiment of the present disclosure is applicable to a situation where a video to be projected is delivered from a source end to a receiving end for playing through DLNA, and the method may be executed by a video screen projection apparatus, where the apparatus may be implemented in a form of software and/or hardware, and optionally, implemented by an electronic device, where the electronic device may be a mobile terminal, a PC end, a server, or the like. As shown in fig. 1, the method is applied to a DLNA screen projection source, and includes:
s110, responding to a screen projection request of the target video, and determining a DLNA screen projection receiving end.
The DLNA screen projection source end may be a video client end of the mobile terminal, and is used for acquiring, recording and storing videos. The DLNA screen projection receiving end can comprise: the digital television, the intelligent set top box and the computer realize a video player of a DLNA protocol and the like, and are used for playing videos transmitted by the screen projection source end. The video transmitted by the DLNA screen projection source may be in various playing formats, and the DLNA screen projection receiving end must support these playing formats to successfully play the video.
Optionally, the determining a DLNA screen projection receiving end in response to the screen projection request of the target video includes: responding to a screen projection request of a target video, and sending a broadcast message carrying a local area network identifier; receiving a broadcast response message, and analyzing the broadcast response message to generate a candidate receiving end list; responding to screen projection clicking operation on a target receiving terminal in the candidate receiving terminal list, and taking the target receiving terminal as a DLNA screen projection receiving terminal.
In this embodiment, the target video may be a certain video selected by a user in a video client of the DLNA screen projection source, or a video currently being played by the video client. When a user clicks a screen projection button of a target video, a screen projection request for the target video is responded, and a DLNA screen projection source end needs to discover screen projection equipment in the unified local area network through a DLNA protocol. The message carrying the local area network identifier can be generated and broadcasted, and at this time, the devices in the same local area network receive the broadcast message and carry the own basic device information in the broadcast response message to return. And the screen projection source terminal analyzes the broadcast response message returned by each device, acquires the basic information of each device, generates a candidate receiving terminal list and displays the candidate receiving terminal list to the user. For example, the candidate recipient list includes: a television in the bedroom 1, a television in the bedroom 2, and a computer in the living room. When the user clicks a certain screen-throwable device in the candidate receiving end list, for example, clicks the television of the bedroom 2, the television of the bedroom 2 is used as a DLNA screen-throwing receiving end.
And S120, acquiring a video playing format list of the DLNA screen projection receiving end.
In this embodiment, a video playing format supported by the DLNA screen projection receiving terminal may be different from a video playing format of the target video sent by the DLNA screen projection source terminal, but only when the DLNA screen projection receiving terminal supports the video playing format of the target video, the screen projection receiving terminal can successfully play the target video, so as to implement screen projection of the target video. Therefore, as shown in fig. 2, before sending a Uniform Resource Locator (URL) of a target video to a screen-casting receiving end, a screen-casting source end may first obtain a video playing format list supported by the screen-casting receiving end to determine whether a currently selected target video can be successfully cast on the screen-casting receiving end.
Optionally, the obtaining of the video playing format list of the DLNA screen projection receiving end includes: sending an information acquisition instruction to the DLNA screen projection receiving end; if a response message returned by the DLNA screen projection receiving end is received, analyzing a video playing format list from the response message; and if the response message returned by the DLNA screen projection receiving terminal is not received, requesting a video playing format list of the DLNA screen projection receiving terminal from a cloud server.
In this embodiment, the device address of the screen projection receiving end may be obtained from the device basic information returned by the DLNA screen projection receiving end through the broadcast response message. And sending an information acquisition instruction to the equipment address of the DLNA screen projection receiving end, namely sending a get instruction to obtain detailed equipment information of the screen projection receiving end. As shown in fig. 2, if a response message fed back by the screen projection receiving end is received, a service list provided by the screen projection receiving end is obtained from the response message, and a video playing format supported by the screen projection receiving end is further determined. And if the response message of the screen projection receiving end is not received, acquiring a video playing format list supported by the screen projection receiving end from the cloud server according to the equipment identification of the screen projection receiving end.
S130, determining a playing address of the target video according to the video playing format list, and pushing the playing address to the DLNA screen projection receiving end to perform target video screen projection.
In this embodiment, according to a video playing format list supported by the screen projection receiving terminal, in combination with a video transcoding service, the screen projection source terminal can acquire the video playing format to obtain a target video supported by the screen projection receiving terminal, and push a playing address of the target video to the screen projection receiving terminal.
Optionally, the determining, according to the video playing format list, a playing address of the target video, and pushing the playing address to the DLNA screen projection receiving end for performing screen projection of the target video includes: acquiring an original playing format of the target video, and matching the original playing format with the video playing format list; if the original playing format hits the video playing format list, the original playing address of the target video is pushed to the DLNA screen projection receiving end to carry out target video screen projection; and if the original playing format does not hit the video playing format list, converting the playing format of the target video into one of the video playing format lists, generating a new playing address and pushing the new playing address to the DLNA screen projection receiving end to carry out target video screen projection.
In this embodiment, in order to improve the play success rate of the video play address pushed by the DLNA, when the DLNA screen projection source end performs screen projection of a target video, the DLNA screen projection source end does not directly push out the original URL of the selected target video, but detects the video play format support condition of the DLNA screen projection receiving end through the DLNA protocol, and the screen projection source end determines whether the original video play format of the target video matches the video play format list supported by the screen projection receiving end according to the information. If the video playing format list comprises the original playing format of the target video, the matching is considered to be successful, and the screen projection receiving end can play the target video in the original playing format, so that the original playing address of the target video can be pushed to the DLNA screen projection receiving end. If the video playing format list does not include the original playing format of the target video, the matching is considered to be failed, and the screen projection receiving end cannot successfully play the target video in the original playing format. At this time, as shown in fig. 2, the video transcoding service may be started, the video playing format of the target video is converted into a video playing format supported by the screen-casting receiving terminal, and a playing address compatible with the screen-casting receiving terminal is generated again and pushed to the DLNA screen-casting receiving terminal to perform the screen casting of the target video.
Optionally, the converting the playing format of the target video into one of the video playing format lists includes: and converting the playing format of the target video into the target video playing format in the video playing format list through a locally deployed transcoding server.
The video transcoding means that a video code stream which is compressed and encoded is converted into another video code stream so as to adapt to different network bandwidths, different terminal processing capacities and different user requirements. Transcoding is essentially a decoding followed by encoding process.
In this embodiment, in order to integrally solve the problem of DLNA play compatibility, a transcoding server is locally deployed and optimized to balance video play, image capture, system operation, and the like. By combining the locally privately-deployed transcoding server with the DLNA, when the video playing format conversion of the target video is required, the locally-deployed transcoding server is started, and the playing format of the target video is converted into the target video playing format in the video playing format list. The target video playing format can be selected according to the encoding capacity of the equipment at the far end of the screen, or according to the size of the target video, or the first video playing format in the video playing format list is directly selected as the target video playing format.
Optionally, after the obtaining the original playing format of the target video and matching the original playing format with the video playing format list, the method may further include: if the original playing format does not hit the video playing format list, locally screening an alternative video set which is the same as the target video content; if the original playing format in the alternative video set hits the target alternative video in the video playing format list, pushing the original playing address of the target alternative video to the DLNA screen projection receiving end; and if the target alternative videos with the original playing formats hitting the video playing format list do not exist in the alternative video set, starting a local transcoding server.
In this embodiment, since the DLNA screen projection source can support multiple playing formats, multiple videos with the same content and different playing formats are stored, for example, the screen projection source includes movie a in the format of movie A, MOV in the format of movie A, AVI in the format of MP 4. Assuming that the target video in the original playing format is movie a in MP4 format, and the video playing format list at the screen projection receiving end includes AVI, RMVB, and MKV, the original playing format does not hit the video playing format list. At this time, the video identical to the target video content, that is, movie a in the AVI format of movie A, MOV, may be screened locally as the alternative video. Since movie-a in AVI format hits the video play format list, the original play address of the video can be pushed to the DLNA screen projection receiving end without starting the local transcoding server to convert the play format of movie-a in MP4 format. And when the candidate videos stored locally do not have videos capable of hitting the video playing format list, starting the local transcoding server to convert the playing format of the target video, and generating a new playing address. At this time, the video with the converted format and the new playing address can be stored, so that video transcoding can be reduced when the video with the same content is subsequently projected.
According to the technical scheme of the embodiment of the disclosure, a DLNA screen projection source end determines a DLNA screen projection receiving end by responding to a screen projection request of a target video; acquiring a video playing format list of the DLNA screen projection receiving end; and determining the playing address of the target video according to the video playing format list, and pushing the playing address to the DLNA screen-casting receiving terminal to perform target video screen casting, so that the problem of low address playing success rate of the receiving terminal on DLNA is solved, the playing format of the video to be screen-cast is unified with the receiving terminal at the source terminal, and the effect that the receiving terminal can successfully play the video to be screen-cast is ensured.
