Embodiment 1
[0036] First, refer to Figure 7 An example electronic system 100 for implementing the video frame processing method, device and electronic system of the embodiments of the present invention will be described.
[0037] Such as Figure 7 A schematic structural diagram of an electronic system is shown, the electronic system 100 includes one or more processing devices 102, one or more storage devices 104, input devices 106, output devices 108, and may also include one or more image acquisition devices 110 , these components are interconnected via bus system 112 and / or other forms of connection mechanisms (not shown). It should be noted that Figure 7 The components and structures of the electronic system 100 shown are exemplary rather than limiting, and the electronic system may also have other components and structures as required.
[0038] The processing device 102 may be a gateway, or an intelligent terminal, or a device including a central processing unit (CPU) or other fo...
Embodiment 2
[0045] Embodiments of the present invention provide a method for processing video frames, such as Figure 8 As shown, the method includes the following steps:
[0046] Step S802, generating a first information address of the target coded video frame; wherein, the information stored in the first information address is used to: indicate the arrangement order of the target coded video frame in the queue of coded video frames;
[0047] The above-mentioned target coded video frame may be a video frame obtained from a camera or a platform, and the target coded video frame may include one or more coded video frames, or may be an incomplete coded video frame. The above-mentioned target coded video frame is usually a data packet of CUVIDSOURCEDATAPACKET structure, which may be referred to as Packet, for example, it may be a piece of encoded YUV or RGB data. In related technologies, the data packet of the encoded video frame contains timestamp parameters. Since the timestamp provided b...
Embodiment 3
[0056] This embodiment provides another video frame processing method. This embodiment focuses on inputting the target coded video frame and the first information address into the decoder, outputting the target decoded video frame corresponding to the target coded video frame, and the target decoding The specific implementation of the step of the second information address corresponding to the video frame (realized by step 902 and step 903), the method includes the following steps:
[0057] Step 901, generate a first information address of the target coded video frame; wherein, the information stored in the first information address is used to: indicate the arrangement order of the target coded video frame in the queue of coded video frames;
[0058] Step 902, decoding the target coded video frame by a decoder to obtain the target decoded video frame;
[0059] The above-mentioned decoding process is the inverse process of encoding, and the compressed (encoded) format can be ch...
