Detailed Description
When a video file is obtained by recording a video using a display device and played, a series of image quality processing is performed to enhance user experience. However, since image quality processing depends on media information such as the frame rate and resolution of the video file itself, image quality processing may have an adverse effect when the information is unstable, and a phenomenon such as a video image being jittered when playing a video may occur, which may result in a poor experience.
Therefore, in order to avoid the image jitter, embodiments of the present invention provide a display device, which can add a local recording mark in the video recording process, and when the mark is identified during video playing, the image quality of the video file is not processed, so as to avoid the jitter of the video image caused by the unstable frame rate and definition of the video file due to the fluctuation of the resource environment of the display device.
A block diagram of a display device according to some embodiments is illustrated in fig. 1. Referring to fig. 1, an embodiment of the present invention provides a display device 200, including: a camera 201, a player 202 and a controller 203. The camera 201 is configured to capture picture images, the controller 203 is configured to receive the picture images captured by the camera and synthesize a video file, and the player 202 is configured to receive the video file synthesized by the controller for playing.
A flow diagram of a video recording method according to some embodiments is illustrated in fig. 2. Referring to fig. 2, in a display device provided in an embodiment of the present invention, when a home recording flag is added in a video recording process, a controller is configured to perform the following steps:
and S11, acquiring the picture image collected by the camera.
And S12, coding the picture image collected by the camera to obtain video frame data.
When a user utilizes the display equipment to record videos, the camera is started, the camera collects picture images in real time, and each frame of picture image collected by the camera is sent to the controller. The picture image includes a picture or a video.
The controller receives each frame of picture image collected by the camera, and codes the current picture image so as to code all picture images in the video recording process into video frame data.
The camera sends the picture images to the controller according to a frame-by-frame rule, and the controller performs coding processing according to the frame-by-frame rule, namely, the controller performs coding processing once every time the controller receives one frame of picture images.
In some embodiments, the method used by the controller to encode the picture image is an H264 encoding rule, and other encoding rules may also be used, which is not specifically limited in this embodiment.
And S13, adding a home terminal recording mark at the initial position of the first frame of the video frame data, wherein the home terminal recording mark is used for marking the video frame data as recorded by the display equipment.
The fluctuation of the resource environment of the display equipment causes the frame rate and the definition of a video file to be unstable, so that the video pictures are jittered, which shows that the resource environment of the display equipment for recording the video is a key factor causing the video pictures to be jittered during playing. Therefore, in order to avoid the picture jitter, if the video file played by the display device is the video recorded by the local terminal, the video file can be directly played without executing the image quality processing process.
In order to accurately determine whether the video file played by the display device is recorded by the local terminal, a local terminal recording mark can be added in the video frame data when the video is recorded. The local recording mark is used for marking the video file as a file obtained by recording and synthesizing the display equipment, namely, the film source of the mark video file comes from the display equipment but not other terminal equipment.
In order to facilitate the display device to quickly and timely determine whether the video file played by the display device is a file recorded by the local terminal itself, the local terminal recording mark may be added to the start position of the first frame of the video frame data when the video is recorded.

And a packaging module is configured in the controller, and the packaging module is used for judging whether the controller receives video frame data for the first time in the video recording process. If the controller receives the video frame data for the first time, the controller acquires the picture image acquired by the camera for the first time and finishes the encoding processing process.
The first video frame data received by the controller is the first frame of the video file, so that in order to facilitate the display device to quickly judge whether the video file to be played is the file recorded by the local terminal itself, the local terminal recording mark can be added at the initial position of the first frame of the video file, and the first frame of the video file refers to the frame corresponding to the first received video frame data.
When the home terminal recording mark is added, the home terminal recording mark is a mark comprising 35 continuous bytes, and the content of the mark is self-defined data. For identification, the home terminal recording mark comprises a plurality of home terminal mark parameters, and the video file recorded by the home terminal is marked by the home terminal mark parameters.
In some embodiments, the controller is further configured to perform the following steps when adding the home recording mark at the start position of the first frame:
step 1321, according to the system setting information, determining a home terminal marking parameter of a home terminal recording mark, where the home terminal marking parameter includes a home terminal type identifier, a home terminal load type identifier, a home terminal UUID, and home terminal custom data, the home terminal type identifier is used to determine that the type of the recording mark is a home terminal recording type, the home terminal load type identifier is a user-defined identifier, the home terminal UUID is a display device custom identifier, and the home terminal custom data is used to identify a film source for recording a video as a display device.
And 1322, acquiring the initial position of the first frame picture, and adding a home terminal recording mark carrying a home terminal type identifier, a home terminal load type identifier, a home terminal UUID and home terminal custom data at the initial position.
The home terminal mark parameters can be obtained according to the system setting information of the display device. If the local terminal display equipment records the video, the corresponding system setting information will generate corresponding information. And determining the home terminal mark parameters of the home terminal recording marks according to the system setting information.
The marking parameters of video recording generally comprise type identification, load type identification, UUID and custom data, wherein the type identification is used for determining the type of a recording mark, including a home terminal recording type and other terminal recording types; the load type identification is used for identifying whether the video is user-defined, the UUID is used for identifying whether the video is user-defined or not, the user-defined data is used for identifying a film source for recording the video, and the film source comprises the video from the display equipment or other terminal equipment.
Therefore, the home terminal mark parameters are used for identifying the recording parameters of the home terminal display equipment, the home terminal mark parameters comprise a home terminal type identifier, a home terminal load type identifier, a home terminal UUID and home terminal self-defined data, the home terminal type identifier is used for determining that the type of the recording mark is the home terminal recording type, the home terminal load type identifier is a user-defined identifier, the home terminal UUID is a display equipment self-defined identifier, and the home terminal self-defined data is used for identifying a film source for recording videos as the display equipment.

Therefore, when the home terminal recording mark is added at the initial position of the first frame picture, the home terminal recording mark can be generated according to the home terminal type mark, the home terminal load type mark, the mark size, the home terminal UUID and the home terminal custom data.
In some embodiments, the home recording mark includes, but is not limited to, the following formats: 0x 000 x 000 x010x 060 x 050 x1b 0x 480 x690x 730x 4d 0x 750 x6c 0x 740 x690x 6d 0x 650 x 640 x690x 610x 540x 610x 670 x 480 x690x 730x 520 x 650 x 630 x6f 0x720x 640 x 650 x720x 80.
It should be noted that the home recording mark includes 35 consecutive bytes, and the lines are only for convenience of explanation, as follows:
0x00 0x00 0x00 0x01//start-code
0x06 0x05 0x1b//nal type+user_data_unregistered type+payloadsize
0x 480 x690x 730x 4d 0x 750 x6c 0x 740 x690x 6d 0x 650 x 640 x690x 610x 540x 610x 67// pseudo UUID, ASCII code "HisMultiMediaTag"

0x80//trailing bits
In the above home recording mark, "0 x 000 x 000 x 000 x 01" is a start mark of the H264 byte stream. "0 x 06" is the home terminal type identifier, which is used to identify the label as the home terminal recording label.

And after the video recording is finished, the controller calls a packaging module to package the video frame data added with the local recording mark to obtain a video file. And the controller sends the synthesized video file to the player for playing.
Therefore, when the display device provided by the embodiment of the invention performs video recording, a home terminal recording mark is added at the initial position of the first frame of the video frame data, so as to identify the video frame data as the display device for recording. When the subsequent display equipment plays the video file, if the local recording mark is identified, the image quality processing is not carried out on the video file, and the phenomenon that the video image shakes easily in the image quality processing process during playing is avoided, so that the user experience is not influenced.

If the recording mark is contained, whether the recording mark is a local recording mark needs to be further judged so as to accurately determine whether the video file is a file recorded by local display equipment.
When judging whether the recording mark is the home terminal recording mark, the judgment can be carried out by judging whether the mark parameter corresponding to the recording mark is consistent with the home terminal mark parameter corresponding to the home terminal recording mark.
And if the marking parameters are consistent with the marking parameters of the local terminal, determining that the recording mark in the video frame data is the recording mark of the local terminal, and further determining that the local terminal recording mark exists in the video frame data, namely the video file is a file recorded by local terminal display equipment.
A flow diagram of a method of determining whether a marking parameter is consistent with a local marking parameter in accordance with some embodiments is illustrated in fig. 7. Referring to fig. 7, in some embodiments, the player, in performing the determining whether the marking parameter is consistent with the home-end marking parameter, is further configured to:
s2331, obtaining the type identification in the marking parameter of the recording mark.
And S2332, if the type identifier is the home terminal type identifier, acquiring the load type identifier in the marking parameters of the recording mark.
And S2333, if the load type identifier is a user-defined identifier, acquiring the UUID in the marking parameters of the recording mark.
And S2334, if the UUID is the self-defined identifier of the display device, acquiring load data in the marking parameters of the recording mark.
And S2335, if the load data is consistent with the self-defined data of the home terminal, determining that the marking parameters are consistent with the marking parameters of the home terminal.
And acquiring the marking parameters of the recording marks identified from the video files received by the player, and extracting the type identifiers of the marking parameters. If the type identification identifies that the type of the mark is the home terminal recording type, the type identification can be determined to be consistent with the home terminal type identification.
And reading the load type identifier in the marking parameter, and if the load type identifier identifies that the mark is a user-defined identifier, determining that the load type identifier is consistent with the local terminal load type identifier.
And reading the UUID in the marking parameters, and if the UUID marks the mark as a display device self-defined mark, determining that the UUID is consistent with the local end UUID.
And reading load data in the marking parameters, and if the load data is completely the same as the self-defined data of the local terminal, indicating that the film source of the video file is a film source recorded by the display equipment.
The marking parameters are consistent with the marking parameters of the local terminal, which indicates that the recording mark identified by the player from the received video file is the recording mark of the local terminal, so that the video file can be directly played when the video frame data contains the recording mark of the local terminal, and the image quality processing of the video file is not needed.
In some embodiments, to ensure that the video file is not processed any more when the home recording flag is identified in the video file, the player is further configured to perform the following steps when the player performs playing the video file if the video frame data contains the home recording flag:
and 241, if the video frame data contains the local recording mark, sending an image quality processing closing notification to the display module, wherein the image quality processing closing notification is used for indicating the display module to close an interface for performing image quality processing on the video file.
Step 242, after receiving a close completion signal returned by the display module in response to the image quality processing close notification, playing the video file, where the close completion signal is used to represent that the display module has closed the interface for performing image quality processing on the video file.
When the display device plays a video, the player needs to call a picture quality processing interface configured in the display device to perform a picture quality processing process, that is, in a normal case, the picture quality processing interface is in an on state. Therefore, in order to ensure that the image quality processing interface is not closed when the local recording mark can be identified in the video file, the image quality processing interface is not required to be closed.
And after judging that the local recording mark exists in the video file, the player generates an image quality processing closing notification and sends the image quality processing closing notification to a display module configured in the display equipment, wherein the display module is used for calling an image quality processing interface to perform image quality processing on the video file.
The display module responds to the image quality processing closing notification, closes the image quality processing interface, and generates a closing completion signal to be fed back to the player after the image quality processing closing notification is completed. And after receiving the closing completion signal, the player decodes the video file and plays the video file.
In some embodiments, if the player does not recognize that the video file from the controller contains the local recording mark, it indicates that the video file is not recorded by the local recording of the display device but is recorded by other terminal devices, and therefore, the image quality processing process can be performed. At this time, the player is further configured to perform the steps of:
step 251, if the video frame data does not contain the home recording mark, sending an image quality processing start notification to the display module, where the image quality processing start notification is used to instruct the display module to start image quality processing on the video file.
Step 252, after receiving the processing completion signal returned by the display module in response to the image quality processing start notification, plays the image quality processed video file.
If the player identifies that the video frame data corresponding to the video file does not contain the local recording mark, the player can perform image quality processing on the video file. Therefore, an image quality processing start notification is generated and transmitted to the display module, and the display module starts image quality processing of the video file in response to the image quality processing start notification.
After the display module calls the image quality processing interface to complete image quality processing of the video file, a processing completion signal is generated and fed back to the player, and after the player receives the processing completion signal, the player decodes the image quality processed video file to play the image quality processed video file.
Therefore, when the display device provided by the embodiment of the invention plays a video, whether the video file contains the local recording mark is firstly identified. And after the video file containing the local recording mark is identified, the video file is not subjected to image quality processing, but is directly played, so that the phenomenon that the video image shakes easily in the image quality processing process during playing is avoided, and the user experience is influenced.
According to the technical scheme, when video recording is carried out, the controller encodes the picture image collected by the camera to obtain video frame data; and adding a home terminal recording mark at the initial position of the first frame of the video frame data, packaging to obtain a video file, and sending the video file to a player for playing. When video playing is carried out, whether video frame data corresponding to a video file contains a local end recording mark or not is identified by the player; and if the local recording mark is contained, directly playing the video file. Therefore, the display device provided by the embodiment of the invention can avoid the frame rate and definition instability of the video file caused by the fluctuation of the resource environment of the display device by adding the local recording mark in the video recording process and identifying the mark during the video playing, so that the video frame jitter phenomenon can not occur during the playing, and the user experience is good.
