Seen from the above description, when user needs to play the video in video capture device by browser, Ke Yixiang
Video capture device sends video playing request, to obtain the video in video capture device, to carry out video playing.Below
In conjunction with attached drawing 2, the operation for playing the video in video capture device to browser is illustrated, specifically comprises the following steps.
Step 201: video capture device receives the video playing request that browser is sent, and carries in video playing request
Video identifier.
It may include multiple and different classes in a video capture device since the type of video capture device is varied
The video of type.For example, when video capture device is spherical camera, since spherical camera can change the angle of acquisition video
Therefore degree when carrying out video acquisition by spherical camera, may obtain the video of multiple and different angles, and for convenience
The subsequent video for distinguishing each shooting angle, it is generally the case that can divide respectively for the video of multiple and different shooting angle shooting
With a video identifier.Therefore, it when user needs to watch the shooting video of some angle, is needed to quickly and accurately obtain
The video to be played, the browser send video playing request in can carry video identifier.
It should be noted that the video identifier be used for the unique identification video, the video identifier can for video title,
Number etc..Certainly, in practical applications, video identifier can be not only carried in video playing request, can also carried open
Begin time, end time etc..
Step 202: video capture device obtains the video data packet of corresponding video based on the video identifier.
Seen from the above description, which can be before receiving video playing request, according to default plan
Collected video is slightly divided into multiple video data packets, therefore, which can be directly based upon the video mark
Know the video data packet for directly acquiring corresponding video.
In addition, time started and end can also be carried due to can not only carry video identifier in video playing request
Time, therefore, when carrying starting and end time in video playing request, which can determine view
Frequency marking knows corresponding video；The corresponding video of video identifier is traversed, to start between from the outset to obtain the video of video
Data packet, until reaching the end time.
When wherein, as that can include the video playing of video indicated by the video data packet in each video data packet

When identical as at the beginning of carrying in video playing request at the beginning of detecting the video for including in video data packet,
Video data packet is obtained since including the video data packet of the time started, when detecting the video indicated in video data packet
At the beginning of it is identical as end time for carrying in video playing request when, stop obtaining video data packet.
In addition, the time started can also be carried in video playing request, without carrying the end time.When the video playing
The time started is carried in request when not carrying the end time, the video capture device can from the outset between start to obtain video
Video data packet, until all video data packet acquisitions after the time started in the video are finished, alternatively, being regarded obtaining
When receiving end playing request during frequency data packet, stop obtaining video data packet.
It is worth noting that due to being integrated with websocket service module in video capture device, the websocket
Service module includes privately owned SDK agreement, can be handled the request received by privately owned SDK agreement, therefore, the present invention
In embodiment, video capture device can execute the operation of step 202 by privately owned SDK agreement.
Step 203: when video capture device often gets a video data packet, which being passed through
Websocket interface is sent to browser.
It can be seen from the above, websocket service module externally provides read-write API (websocket interface), by this
The data interaction between video capture device and other equipment may be implemented in API, therefore, when video capture device often gets one
When a video data packet, which can be sent to by browser by websocket interface.
It should be noted that the websocket interface can be embodied by websocket function, for example, websocket_
Write_data function may be other websocket functions in practical applications certainly.Therefore, work as video capture device
When sending video data packet by websocket interface, video counts are as sent by websocket_write_data function
According to packet.
Step 204, when browser receives the video data, video data packet is decoded by default decoder
And rendering, to play the video.
It should be noted that the default decoder can be page script language decoders (JS decoder).Certainly exist
It may be the relevant decoder of other JS in practical application.
In addition, the video data packet is decoded and is rendered by browser, phase can be referred to play the operation of the video
Pass technology, the embodiment of the present invention no longer carry out one to this and repeat.
