Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all 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 application.
At present, movies are usually shot and shown at 24fps, and the frame rate is increased on the basis of 24fps, for example, from 24fps to 48fps, which is equivalent to increasing one frame content between each frame of pictures, so that more information is obtained in a unit time of a viewer, and the viewing effect becomes better.
With the continuous improvement of the photographing apparatus, the photographing apparatus can perform photographing at various different frame rates. For example, movies shot at 24fps, 48fps, and 120fps include a plurality of frame rates in the later-formed DCP. However, the current playing devices such as a movie server only support video playing at a frame rate, which results in poor visual effect of video playing.
Based on the above problem, the present application provides a video processing method and apparatus, where a corresponding frame rate tag is added to a video, a frame rate corresponding to the video to be played is determined according to the frame rate tag of the video to be played, and the video to be played is decoded and played based on the frame rate, so as to achieve an enhancement of a playing effect including the video, and further enhance a visual effect of video playing.
Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present application. As shown in fig. 1, in this application scenario, a movie including a multi-frame rate is played by the movie server 110 and projected by the projector 120 onto the screen 130 for imaging. The specific implementation process of the server 110 playing the movie containing multiple frame rates can be seen in the schemes of the following embodiments.
It should be noted that fig. 1 is only a schematic diagram of an application scenario provided in this embodiment, and this embodiment of the present application does not limit the devices included in fig. 1, and also does not limit the positional relationship between the devices in fig. 1. For example, in the application scenario shown in fig. 1, a data storage device may be further included, and the data storage device may be an external memory with respect to the server 110 or an internal memory integrated in the server 110.
Fig. 2 is a flowchart of a video processing method according to an embodiment of the present application. The method of the embodiment of the application can be applied to electronic equipment, and the electronic equipment can be a server or video playing equipment such as a television, a projector, a tablet computer or a desktop computer.
As shown in fig. 2, the video processing method according to the embodiment of the present application includes the following steps:
s201, obtaining a target frame rate mark of a video to be played.
In practical applications, when a video is generated, a frame rate flag corresponding to the video may be added, where the frame rate flag is used to identify a frame rate of the corresponding video. For convenience of description, in the embodiment of the present application, the frame rate flag of the video to be played is referred to as a target frame rate flag. In a first specific implementation, video segments with the same frame rate in a video to be played are identified by a target frame rate mark; in a second specific implementation, each frame in the video to be played has a corresponding target frame rate tag. In comparison, in the second specific implementation, the data amount of the target frame rate flag corresponding to the video to be played is greater than the data amount of the target frame rate flag corresponding to the video to be played in the first specific implementation.
Illustratively, the target frame rate of the video to be played is 24fps, and accordingly, if the frame rate flag corresponding to 24fps is 0001, the target frame rate flag of the video to be played is 0001.
Or, the target frame rate of the video to be played includes 24fps and 48fps, and accordingly, the frame rate flag corresponding to 24fps is 0001, and the frame rate flag corresponding to 48fps is 0010, and then the target frame rate flags of the video to be played are 0001 and 0010. In this example, assuming that the video to be played contains 100 frames, where the frame rates of the 1 st to 50 th frames are 24fps and the frame rates of the 51 st to 100 th frames are 48fps, corresponding to the first specific implementation, the 1 st to 50 th frames may be marked by one 0001, and the 51 st to 100 th frames may be marked by one 0010; alternatively, corresponding to the second specific implementation, the 1 st to 50 th frames may be respectively marked with 50 0001, and the 51 st to 100 th frames may be respectively marked with 50 0010; alternatively, frames 1 to 50 may be marked with one 0001, and frames 51 to 100 may be marked with 50 0010, respectively; and the specific implementation can be set according to actual requirements, and the embodiment of the application is not limited.
Correspondingly, in the playing process, the target frame rate mark corresponding to each frame may be sequentially obtained according to the playing sequence of each frame of the video to be played, or the target frame rate marks corresponding to multiple frames may be obtained. Illustratively, the target frame rate tag of the video to be played may be stored in the configuration data of the DCP, in which case the target frame rate tag of the video to be played may be obtained from the configuration data.
In some embodiments, the video to be played includes video segments with at least two frame rates, where the target frame rate markers corresponding to different video segments are different, and the obtaining of the target frame rate marker of the video to be played may include: and acquiring a target frame rate mark of the corresponding video segment.
Illustratively, the video to be played contains video segments at three frame rates, which are 24fps, 48fps and 120fps respectively. Optionally, the frame rate flag corresponding to the video segment of 24fps is, for example, 0001, the frame rate flag corresponding to the video segment of 48fps is, for example, 0010, and the frame rate flag corresponding to the video segment of 120fps is, for example, 0011, and the target frame rate flag of the video segment of each frame rate may be obtained. The target frame rate markers corresponding to different video segments included in the video to be played are stored in the configuration data, so that the target frame rate markers corresponding to the video segments can be obtained from the configuration data.
S202, determining the decoding frame rate as the target frame rate corresponding to the target frame rate mark.
After the target frame rate mark of the video to be played is obtained, the decoding frame rate can be determined to be the target frame rate corresponding to the target frame rate mark.
And S203, decoding the video to be played by adopting the decoding frame rate.
In practical applications, video coding is usually performed on video to remove redundancy in spatial and temporal dimensions for the convenience of storage, transportation or reduction of data volume. It is understood that the video encoding process refers to performing related processing on the original video by using a video encoding mode. The video coding mode comprises a mode of converting a file in an original video format into a file in another video format through a compression technology. Therefore, the video to be played is decoded during actual playing.
Specifically, a decoder is set based on the decoding frame rate to decode the video to be played. Illustratively, the image portion of the DCP is a Joint Photographic Experts Group (JPEG) 2000 compressed file, and a Field Programmable Gate Array (FPGA) based decoder may be used to decode the video to be played. It should be noted that, the specific decoding manner may refer to the related art, and is not described herein again.
S204, determining the playing parameter of the video to be played as a target playing parameter corresponding to the target frame rate.
The playing parameters corresponding to different frame rates may be the same or different. Specifically, the playing parameter with a fixed frame rate when the playing effect is the best can be set as the playing parameter corresponding to the frame rate. Therefore, in the playing process, the electronic equipment can determine the target playing parameter according to the target frame rate of the video to be played, so that the video to be played has a good playing effect, and the visual experience of a user is further improved.
Optionally, the playing parameter may include at least one of a frame rate, a resolution, a sound format, a color space, a code rate, and a refresh rate, which is not limited in this application. The frame rate, i.e., the frequency (rate) at which the bitmap image in units of frames continuously appears on the display, is 24 fps; the resolution refers to the number of pixels displayed on the screen, for example, the resolution of a movie screen is 2048 × 858, that is, the number of horizontal pixels is 2048, the number of vertical pixels is 858, and the higher the resolution is, the larger the number of pixels is, the finer the display effect is; sound format, i.e. digital audio format, such as dolby 5.1 channel, dolby panound; the color space is also called color gamut, is a method for encoding a color, and also refers to the sum of colors that a technical system can generate, namely the area that can be covered in color, for example, the color space is a P3 color gamut, which can match as much as possible all color gamuts that can be shown in a movie scene, and can better satisfy the experience of human vision; the code rate refers to the number of data bits transmitted in unit time during data transmission, and the higher the code rate is, the higher the precision is, for example, the code rate is 250M/s; the refresh rate refers to the number of times the electron beam repeatedly scans the image on the screen. The higher the refresh rate, the better the displayed image (picture) stability. The refresh rate can be divided into a vertical refresh rate and a horizontal refresh rate, and the commonly mentioned refresh rate is generally referred to as a vertical refresh rate. The vertical refresh rate indicates how many times an image of the screen is redrawn per second, i.e., the number of screen refreshes per second, in Hz (hertz). The higher the refresh rate, the more stable the image, the more natural and clear the image display, and the less impact on the eyes. The lower the refresh frequency, the more flickering and jittering the image, and the faster the eye becomes tired.
And S205, playing the decoded video based on the target playing parameter.
The video processing method provided by the embodiment of the application determines that the decoding frame rate is the target frame rate corresponding to the target frame rate mark by acquiring the target frame rate mark of the video to be played, decodes the video to be played by adopting the decoding frame rate, determines that the playing parameter of the video to be played is the target playing parameter corresponding to the target frame rate, and plays the decoded video based on the target playing parameter. According to the video playing method and device, the corresponding target frame rate can be determined according to the target frame rate mark of the video to be played, and then the corresponding decoding frame rate and playing parameters are determined according to the target frame rate, so that the video to be played is decoded and played respectively by adopting the decoding frame rate and the playing parameters corresponding to the target frame rate, and the visual effect of video playing is improved.
Fig. 3 is a flowchart of a video processing method according to another embodiment of the present application. On the basis of the above embodiments, how to decode and play the video to be played according to the target frame rate mark is further described in the embodiments of the present application. As shown in fig. 3, a video processing method according to an embodiment of the present application may include:
s301, obtaining configuration data of a video to be played, wherein the configuration data comprises a target frame rate mark.
Illustratively, the DCP corresponding to the video to be played includes a metadata file for storing the configuration data. The configuration data includes a target frame rate flag corresponding to each frame, for example, for a first frame of the video to be played in the configuration data, the corresponding target frame rate flag is 0001, the target frame rate flag corresponding to a second frame is 0010, and different target frame rate flags respectively correspond to different frame rates of the video to be played.
S302, obtaining the target frame rate mark of the video to be played from the configuration data.
In this embodiment, S301 and S302 are further refinements of the above step S201.
S303, acquiring the corresponding relation between the frame rate and the frame rate mark from the configuration file.
The configuration file comprises the corresponding relation between the frame rate and the frame rate mark. Illustratively, as shown in table 1, the frame rate flag 0001 corresponds to a frame rate of 24fps, the frame rate flag 0010 corresponds to a frame rate of 48fps, the frame rate flag 0011 corresponds to a frame rate of 120fps, and so on are contained in the configuration file.

| Serial number | Frame rate marking | Frame rate |
| 1 | 0001 | 24fps |
| 2 | 0010 | 48fps |
| 3 | 0011 | 120fps |
| …… | …… | …… |
S304, according to the corresponding relation between the frame rate and the frame rate mark, determining the target frame rate corresponding to the target frame rate mark.
In obtaining the target frame rate tag of the video to be played, from the corresponding relationship between the frame rate and the frame rate tag represented in table 1, the corresponding relationship between the frame rate and the frame rate tag may be queried according to the target frame rate tag, and the target frame rate corresponding to the target frame rate tag is determined.
Illustratively, if the target frame rate of the video to be played is marked as 0001, and the frame rate corresponding to the frame rate in the configuration file is 24fps when the frame rate is marked as 0001, it may be determined that the target frame rate corresponding to the target frame rate mark 0001 is 24fps, and so on.
S305, determining the decoding frame rate as the target frame rate.
It should be noted that steps S303 to S305 are further detailed in the above step S202.

S307, determining target playing parameters corresponding to the target frame rate according to the corresponding relation between the frame rate and the playing parameters.
Optionally, the configuration file may further include a corresponding relationship between the frame rate and the playing parameter. Illustratively, the configuration file includes the following table 2, as shown in table 2, the frame rate is 24fps corresponding to a refresh rate of 24 frames, the frame rate is 48ps corresponding to a playback parameter of 48 frames, and so on. It should be noted that, table 2 is described by taking the playback parameter as the refresh rate as an example, but the present application is not limited thereto.
