Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, after receiving a GDR code stream transmitted by an image, a terminal device decodes the GDR code stream and then realizes local playing. In addition, the terminal device also needs to store the GDR code stream in a local memory, which needs to encode the decoded image frame and then store the encoded code stream in the local memory, that is, the process of the terminal device encoding the GDR code stream includes frame-by-frame decoding- > frame-by-frame encoding, but the efficiency of the frame-by-frame encoding is low.
Therefore, an embodiment of the present invention provides a method for encoding a GDR code stream, and fig. 1 is an application scenario diagram provided in the embodiment of the present invention. Referring to fig. 1, an image capturing device 20 captures a video, and then encodes, compresses, and the like the video to generate a GDR code stream, uploads the GDR code stream to a streaming media server 30, and then forwards the GDR code stream to a terminal device 10 by the streaming media server 30. Or, the image acquisition device 20 acquires a video, then performs processing such as encoding and compression on the video to generate a GDR code stream, and directly sends the GDR code stream to the terminal device 10. The transmission mode of the GDR code stream may be set according to a specific scenario.
While decoding the GDR code stream to play the video, the terminal device 10 encodes the GDR code stream and stores the encoded GDR code stream in a local memory, a cache, or a cloud (not shown in the figure). The invention relates to a GDR code stream coding method, which has the inventive concept that:
when receiving a certain frame, the terminal device combines the decoded image frame when playing the video to obtain the image frame corresponding to the certain frame, the image frame is the complete I frame of all image information, and then copies the preset number of frames after the certain frame in the GDR code stream to the complete I frame, so as to obtain a coding group. Repeating the above steps to obtain multiple coding groups, thereby coding the GDR code stream into a coding code stream.
Therefore, in the process of encoding the GDR code stream, the terminal equipment only performs encoding operation on one frame, and the rest frames do not need to be processed, so that the data volume of encoding can be greatly reduced, and the encoding efficiency is improved.
Fig. 2 is a schematic flow diagram of a GDR code stream encoding method provided in an embodiment of the present invention, and referring to fig. 2, a GDR code stream encoding method includes step 201 and step 202, where:
and 201, acquiring a GDR code stream.
In this embodiment, the processor in the terminal device 10 may obtain a GDR code stream sent by the image capturing device 20. For example, the processor may read the GDR code stream from local memory, cache, or cloud.
The GDR code stream obtained by the processor in this embodiment may include a plurality of image code stream groups, where a dashed box in fig. 3 shows one image code stream group. Each image code stream group includes a plurality of P frames containing I slices (slices) and a plurality of normal P frames, and the P frames containing I slices and the P frames not containing I slices in the image code stream group may be set according to a specific scene, which is not limited herein. Referring to fig. 3, each image bitstream group in this embodiment includes 4P frames including I slices (slices) and 41 normal P frames, i.e., each image bitstream group includes 45P frames. The 4P frames including I slice (slice) are composed of: the first frame consists of I slice, P slice and P slice; the second frame consists of P slice, I slice, Pslice and P slice; the third frame consists of P slice, I slice and P slice; the composition of the fourth frame is Pslice, P slice and I slice. In addition, in this embodiment, the processor can recover a correct frame of image, i.e., a video picture, from the 4P frames including I slice.
202, encoding the GDR code stream into an encoded code stream comprising a plurality of encoding groups; the first frame of each coding group is a complete I frame containing all image information, and the preset number of frames after the first frame is the frames in the copied GDR code stream.
In this embodiment, the encoding of the GDR code stream into an encoded code stream including a plurality of encoding groups by the processor in the terminal device 10, referring to fig. 4, includes:
first, the processor acquires an image code stream group in the GDR code stream (corresponding to step 401). Taking dividing an image code stream group as an example, obtaining a first P frame containing I slice in a GDR code stream, taking the first P frame containing I slice as a first frame of the image code stream group, and taking the following 3P frames containing I slice and 41 common P frames as subsequent frames of the first frame to obtain an image code stream group.
It should be noted that the processor may divide the GDR code stream into a plurality of image code stream groups, and then perform subsequent steps on the plurality of image code stream groups in parallel. Of course, the processor may also divide only one image bitstream group at a time, and perform the subsequent steps for the image bitstream group.
The processor then acquires the last normal P frame of each image bitstream group (corresponding to step 402). With continued reference to fig. 3, the last normal P frame of the image bitstream group is shown with an arrow.
The processor then encodes the last normal P frame as a complete I frame containing all image information and takes the complete I frame as the first frame of the encoded group (corresponding to step 403). Since the terminal device 10 also needs to play the video, there is a decoding process of the GDR code stream, and the decoding manner may refer to the related art scheme, which is not limited herein.
In the decoding process, a complete image frame for display may be obtained, referring to fig. 5, the processor may read the complete image frame (i.e., a reference image frame) at a specified position and obtain YUV data of a last normal P frame (corresponding to step 501), and encode the last normal P frame into a complete I frame containing all image information by combining the reference image frame and the YUV data (corresponding to step 502), where the encoding method may refer to a scheme of the related art, such as an H264 encoding method, which is not limited herein. Wherein the specified location may be a cache of the terminal device.
Finally, the processor copies the frame between the last normal P frame in the image bitstream group and the last normal P frame in the subsequent image bitstream group to the encoding group as a subsequent frame to the first frame of the encoding group (corresponding to step 404).
Referring to fig. 6(a), the processor acquires a first P frame containing I slice, that is, a first P frame in a second dashed frame from the left in fig. 6(a), and then encodes a last normal P frame in an image bitstream group before the first P frame containing I slice into a complete I frame as a first frame of an encoding group in an encoding bitstream. Then, the processor copies the second, third, and fourth P frames containing I slice and all the normal P frames before the last normal P frame in the second dashed frame as the subsequent frames after the first frame of the coding group, so as to obtain a coding group (indicated by dashed frame) of the coding stream GDR' shown in fig. 6 (b). Repeating the steps to obtain the code stream GDR'.
With continued reference to fig. 6(b), when the processor stores the code stream GDR', since the GDR code stream before the first complete I frame cannot form a code group, the processor discards the GDR code stream before the first complete I frame, thereby saving the storage space.
It should be noted that, in this embodiment, when the encoded code stream GDR' is decoded again, the processor may repair the complete I frame (i.e., the first frame in the encoding group) by using the P frame containing I slice after the complete I frame, so as to control the picture difference within the lowest range.
Therefore, in this embodiment, except for the first frame in the encoding group, the other frames only need to be copied, so that the encoding calculation amount of 44/45 can be reduced, which is beneficial to reducing the time required for encoding and improving the encoding efficiency.
