Embodiment 1

[0066] The embodiment of the present invention provides a video data retrieval method, such as figure 1 shown, including the following steps:

[0067] Step S11, determining the target video resource to be called.

[0068] As an optional implementation, such as figure 2 As shown, step S11 may include:

[0069] Step S111, receiving a selection command for selecting a video resource. Wherein, the video resources are all located in the video resource list on the resource retrieval interface, and the user can select the corresponding video resource as required, and at this moment, the selection command for selecting the video resource is received.

[0070] Step S112, judging whether a drag command is received, wherein the drag command is used to drag the video resource selected by the selection command to a preset area;

[0071] Step S113, when the drag command is received, the video resource dragged to the preset area is taken as the target video resource.

[0072] In this w...

Embodiment 2

[0111] The embodiment of the present invention provides a video data retrieval device, such as Figure 4 As shown, it includes a first determining unit 21 , a second determining unit 22 , a first judging unit 23 , a first calling unit 24 and a second calling unit 25 . in,

[0112] The first determining unit 21 is configured to determine the target video resource to be called.

[0113] The second determination unit 22 is configured to determine a decoding channel corresponding to the target video resource, wherein the decoding channel is set on a decoder.

[0114] The first determining unit 23 is configured to determine whether the video data corresponding to the target video resource is video conference data or surveillance video data.

[0115] The first calling unit 24 is used to call the interface corresponding to the video conference data when the video data is video conference data, and call the code stream corresponding to the video conference data to the decoding chann...

Embodiment 3

[0124] The embodiment of the present invention provides a specific example of a video data retrieval method. Include the following steps:

[0125] 1. All resources have been entered into the system and stored. When scheduling on a large screen, you can select resources to be scheduled on the large screen according to the resource list displayed on the left side of the interface, and drag them to the large screen;

[0126] 2. According to the designed redis cache information, check whether the channel of the decoding board is occupied. If the corresponding decoding channel is empty, judge the resource type currently scheduled. If it is a video conference terminal, directly control the video conference terminal SDK and call The code stream is sent to the decoding channel port to realize resource decoding on the large screen; if it is a monitoring resource, the JNI interface is called to send the code stream to the designated decoding channel port through the monitoring platform;...

Abstract

The invention relates to the technical field of data retrieval, and discloses a video data retrieval method and a device thereof, wherein the method comprises the following steps of: determining a target video resource to be retrieved; determining a decoding channel of the target video resource, wherein the decoding channel is arranged on a decoder; determining whether the video data correspondingto the target video resource is video conference data or surveillance video data; if it is the video conference data, invoking an interface corresponding to the video conference data, and retrievinga code stream corresponding to the video conference data through the interface corresponding to the video conference data to a decoding channel; and if it is the surveillance video data, invoking an interface corresponding to the surveillance video data, and retrieving a code stream corresponding to the surveillance video data through the interface corresponding to the surveillance video data to the decoding channel. No need to set different decoders for two different types of video data such as video conference data and surveillance video data, the invention improves the data retrieval speed,and the retrieval mode is simple and fast.

Description

technical field [0001] The invention relates to the technical field of data scheduling, in particular to a video data retrieval method and device. Background technique [0002] The visual command and dispatch system refers to the integration of command and dispatch, video conferencing, network monitoring and other key business functions on the same business platform to realize real-time interaction of audio and video services and meet the needs of users for high-definition visual command and dispatch. At the same time, in the application of multi-level command and dispatch, users can conduct two-way or multi-directional command and dispatch more intuitively and reliably through video conferencing, equipped with powerful image and data transmission functions, and can also view network monitoring images simultaneously. [0003] With the development of information technology, the command and dispatch system, as a means of modern and efficient remote communication, dispatch and ...
