Example 3
The technical solutions of the embodiments of the present invention are described below by way of examples in connection with preferred embodiments.
In a distributed system, in the OSD menu of the agent node or in the large screen management software, the user wants to be able to view the content of the video source in real time in the source list, so it is necessary to transfer the dynamic video of the input source to the OSD of the agent node or to the large screen management software.
In the related technology, a Haesi chip scheme is used, and because the Haesi chip has more hard coding resources, the Haesi chip usually directly uses the hardware coding resources inside the Haesi chip to carry out coding, then the coded data is pushed to a local area network, and after the receiver pulls the stream, the coded data is decoded and displayed. However, this requires sufficient hardware coding resources to be realized.
The embodiment can realize the picture display of pre-monitoring under the condition of not using hardware coding resources of a chip, and can dynamically acquire the source content required by the display interface when the number of the input video sources is more so as to ensure the performance efficiency.
The above-described method of this embodiment is further described below.

In this embodiment, a bare data transmission mode is adopted between the internal encoding and decoding nodes, the FPGA chip in each encoder 33 first compresses each frame of the original video data into 480x270 size, and can transmit the compressed data to the encoder node ARM, where the ARM can directly push the uncoded data to the decoder 33.
In this embodiment, a user opens the APP end 31, the APP end 31 may display a default page, the user may further open a large-screen editing page of the APP end 31, and trigger the APP end 31 to send a request for requesting 8-way preview source data and 8-way layer source data to the decoder 33 through the wireless router 32, where the request may be sent to the master node of the decoder 33, the master node of the decoder 33 may respond to the request, and obtain corresponding 16-way source data from 480x270 compressed data in the encoder node ARM through the switch 34, where the 16-way source data may include 8-way preview source data and 8-way layer source data. The decoder 33 may arrange the 16 source numbers on one integral 1920 × 1080 canvas for splicing, then perform soft coding on the spliced video picture through the decoder node, and push the data after the soft coding to the APP terminal 31 in a multicast manner by using the RTSP protocol, and perform soft decoding through the APP terminal 31 and rendering to the interface of the APP terminal 31.
Optionally, the soft-coded data in this embodiment may be an RTSP video stream, the decoder 33 may return position data of the RTSP video stream to the APP terminal 31, for example, a Uniform Resource Locator (URL) address, the APP terminal 31 may obtain the RTSP video stream based on the URL address, decode and cut the RTSP video stream, and display a corresponding video picture, so that the APP terminal 31 may display an initialized video picture, and then a user may see the initialized video picture at the APP terminal 31. The preview source data and the layer source data in the RTSP video stream respectively have corresponding position data.
Optionally, the user may slide the preview source list of the APP terminal 31, modify, through operations such as layer windowing and source switching, the request sent to the decoder 33 for requesting 8-way preview sources and 8-way layer sources through the wireless router 32, pull new 16-way source data from the decoder 33, and return new 16-way source data from the encoder 35 to the decoder 33. The decoder 33 fills the new 16-way source data, successfully returns the new 16-way source data to the APP terminal 31, and the APP terminal 31 refreshes soft decoding and cutting to display a new video picture corresponding to the new 16-way source data, so that the user can see the latest video picture. Wherein, the APP terminal 31 can perform a silent frame display before the decoder 33 successfully returns the new 16-channel source data to the APP terminal 31.
It should be noted that, in the chip used in the video processing system of this embodiment, the encoding resource is only 4K60, so that the input pre-monitored video is transmitted in a bare data transmission manner; the resolution of the video data compressed by the encoder 35 is 480x270, and the frame rate is 15 frames; the APP end 31 fills the corresponding video source data through the protocol dynamic control decoder 33.
As another alternative example, the encoder and the decoder of this embodiment may transmit video data in an H264 format, where an FPGA chip in each encoder compresses each frame of original video data into 480 × 270, and transmits the compressed video data to an ARM, and the ARM may encode the video data into an H264 format video in a CPU soft coding manner, and then may use an RTSP protocol to stream the video data to a local area network. Optionally, the decoder may dynamically connect to different encoders IP according to the display requirements of the display interface of the client, and obtain different H264 video streams through the encoders IP. And then the decoder firstly performs soft decoding on the H264 video stream by using the CPU to obtain a video frame, and then transmits a video picture corresponding to the video frame to an OSD menu interface of the client.
The video processing method of the embodiment is a transmission scheme of a pre-monitoring picture, and the pre-monitoring picture can be displayed by the method under the condition of not using hardware coding resources of a chip; when the number of the input sources is large, the video data corresponding to the video pictures to be displayed on the display interface are dynamically acquired, so that the performance efficiency is ensured.
