[ first embodiment ] A method for manufacturing a semiconductor device
As shown in fig. 1, a first embodiment of the present invention provides a DRM-based video switching display method, which is suitable for video switching display under an embedded platform. Specifically, the method for switching and displaying the video based on the DRM provided by the embodiment of the present invention includes, for example, the steps of:
s11: reading an end video frame of a first video displayed on a display screen based on DRM;
s13: copying the ending video frame to a shared memory to obtain a transition video frame;
s15: reading the transition video frame, and displaying the transition video frame to the display screen based on DRM after the ending video frame stops being displayed;
s17: reading a second video;
s19: and stopping displaying the transition video frame and displaying the second video to the display screen based on DRM.
Therefore, in the transition time period between the first video and the second video, the video frame currently displayed by the first video is copied to the shared memory and the video frame is continuously played and ended in the transition time period, so that the black field phenomenon in the transition time period is avoided, and the user experience is improved.
Specifically, the reading of the end video frame of the first video displayed on the display screen based on DRM of step S13 includes:
copying the ending video frame to a shared memory through a main video playing process to obtain a transition video frame; and
and sending a video frame playing ending signal to the shared memory.
In step S15, the reading the transition video frame and displaying the transition video frame to the display screen based on DRM after the ending video frame stops being displayed includes:
reading the ending video frame playing signal from the shared memory through a video auxiliary playing process, and reading the transition video frame from the shared memory according to the ending video frame playing signal; and
and displaying the transition video frame to the display screen.
Further, the reading the second video of step S17 includes:
reading and decoding the second video through a video main playing process; and
and sending a transition video frame playing stopping signal to the shared memory after the decoding is finished.
In step S19, the stopping of displaying the transition video frame specifically includes:

and stopping displaying the transition video frame according to the transition video frame playing stopping signal.
The displaying the second video to the display screen based on DRM of step S19 includes: and displaying the second video on the uppermost layer of the display screen.
In another embodiment of the present invention, the displaying the second video to the display screen based on DRM in step S19 is specifically caching and outputting the second video to the display screen in a ping-pong operation manner.
In another embodiment of the present invention, before displaying the second video to the display screen based on the DRM, the DRM-based video switching display method further includes decoding the second video.
In order to facilitate understanding of the present invention, the steps of the DRM-based video switching display method according to the present embodiment will be described in detail with reference to fig. 2A and 2B.
The DRM-based video switching display method provided by the embodiment of the present invention can be implemented, for example, by an embedded processor of an embedded device. Here an embedded device such as an embedded video processing device. For example, as shown in FIG. 2A, an embedded video processing device is connected to a display screen. The display screen may be, for example, an LED display screen, or may also be other display screens such as an LCD, and the invention is not limited thereto. The embedded video processing device mainly comprises an embedded processor, a programmable logic device connected with the embedded processor and a volatile memory connected with the embedded processor. The Programmable logic device is, for example, an FPGA (Field-Programmable Gate Array), and is configured to process an input video and output the processed video data to a subsequent device, such as a display control card and a display device. The volatile memory is, for example, a DDR (Double Data Rate SDRAM) for buffering some Data during the operation of the video embedded video processing device. Generally, the embedded processor plays the whole video scheme through the created video main playing process, and the whole video scheme comprises a plurality of videos. The video main playing process plays a plurality of videos, for example, including a first video and a second video, according to a preset playing sequence. The DRM-based video switching display method provided by the embodiment of the present invention can be implemented, for example, by an embedded processor through interaction of two processes, for example, a video main playing process and a video auxiliary playing process (see fig. 2B), so as to avoid a black field problem occurring when a currently playing first video is switched to playing a second video, and a specific process is as follows.
Firstly, after receiving a video switching signal, the embedded processor reads an ending video frame of a first video of an uppermost layer displayed on a display screen in a DRM mode according to the video switching signal and through a video main playing process. Because the first video is displayed on the uppermost layer of the display screen in the DRM mode, it can be ensured that the display picture of the first video is not blocked or covered by the display pictures of other videos. . The video switching signal here may be, for example, a signal generated by a video switching operation performed by a user, or may be an automatic switching signal generated according to a preset playing sequence setting. The ending video frame here may be the last frame of the first video, or may be the current video frame being displayed on the display screen when the embedded processor receives the switching signal.
And secondly, copying the ending video frame to a shared memory by the embedded processor to obtain a transition video frame. Specifically, the embedded processor copies the ending video frame to the shared memory of the volatile memory through the video main playing process to obtain the transition video frame. After the embedded processor copies the ending video frame to the shared memory through the video main playing process, the video main playing process sends an ending video frame playing signal to the shared memory. The shared memory here is, for example, a part of the volatile memory, and may be a memory space provided in the volatile memory for being accessed by a plurality of processes (as shown in fig. 2A), or may be another volatile memory separately connected to the embedded processor. Multiple processes may communicate through a shared memory.
And then, the embedded processor reads the transition video frame and displays the transition video frame to the display screen in a DRM mode after the ending video frame stops being displayed. Specifically, when a video frame playing ending signal sent by the video main playing process is acquired from the shared memory, the embedded processor reads the transition video frame from the shared memory through the video auxiliary playing process, and then after the video frame ending of the first video is displayed, the video auxiliary playing process displays the read transition video frame on the display screen. The display mode of the transition video frame is the same as that of the ending video frame of the first video, for example, a DRM display frame is adopted, so that the auxiliary video playing process can normally display the transition video frame to the display screen when the resource of the display cache of the display screen is cancelled after the main video playing process exits. It should be noted here that the video auxiliary playing process may always display the transition video frame in the uppermost layer of the display screen until the next video, i.e., the second video, starts to be played. The video auxiliary playing process and the video main playing process are communicated through a shared memory, for example, a video frame playing ending signal, a video playing stopping signal and the like are transmitted through the shared memory.
The embedded processor then reads the second video to be played. Specifically, the embedded processor restarts the video main playing process, loads and reads data of the starting video frame of the second video through the restarted video main playing process, and decodes the starting video frame of the second video. And after the decoding of the initial video frame of the second video is finished, the video main playing process sends a transition video frame playing stopping signal to the shared memory.
And finally, the embedded processor stops playing and displaying the transition video frame and displays the second video on the display screen. Specifically, the embedded processor acquires a transition video frame playing stopping signal from the shared memory through the video auxiliary playing process, and stops displaying the transition video frame according to the transition video frame playing stopping signal. And then the embedded processor displays the second video on the display screen from the initial video frame to the video frame by video frame through the video main playing process. Similarly, the first video is displayed in the same manner as the current video frame of the first video, for example, by using a DRM display frame displayed on the uppermost layer of the display screen. The embedded processor completes the display and playing of other videos in the whole playing scheme in the same way. Therefore, the embedded processor copies the ending video frame to the shared memory through the main video playing process, and plays the ending video frame again in the transition time period existing in the shared memory by adopting the auxiliary video playing process so as to wait for reading and displaying of the second video, so that the switching of the video without the black field in the transition time period is realized, and the video playing control effect and the user experience degree are improved.
In addition, for different embedded processing chips, the embedded processor can call the corresponding hardware decoding library to decode the video to be displayed, so that the decoding efficiency can be greatly improved, and the CPU occupation rate is reduced. For example, the embedded processor decodes each video frame of the second video by FFMPEG into video frame data in YUV format. Of course, the decoding here can also be accomplished by other decoding chips, and the invention is not limited here.
Further, the embedded processor may buffer, output, e.g., via a video master play process, video frames of the second video onto the display screen in a ping-pong operation prior to outputting the second video onto the display screen. Specifically, after the video main playing process reads the second video from the shared memory, the starting video frame of the second video is stored in the first buffer memory in the first period, the second video frame of the second video is stored in the second buffer memory in the second period, and the starting video frame in the first buffer memory is simultaneously output to the display screen for display, the third video frame of the second video is stored in the first buffer memory in the third period, and the second video frame in the second buffer memory is simultaneously output to the display screen for display, so that the second video is alternately buffered and output to the display screen. The embedded processor adopts the double-buffering mechanism, such as a ping-pong operation mode of buffering one frame and outputting and rendering one frame to display the second video, so that the phenomenon that the video display picture is torn and blocked due to the untimely preparation of the video frame data of the second video is avoided.
In summary, the embedded processor in the embodiment of the present invention copies the ending video frame to the shared memory through the main video playing process, and uses the auxiliary video playing process to play the ending video frame again within the transition time period existing in the shared memory to wait for reading and displaying of the second video, so as to implement black-field-free video switching within the transition time period, and improve the video playing control effect and the user experience. In addition, when the video is displayed, the video frames are cached and output in a ping-pong operation mode, the problem of picture blocking or tearing caused by insufficient preparation of the video frame data is avoided, and the display effect is further improved.
