Wherein, the method includes: when the first interface corresponding to the first video is displayed on the electronic device, receiving the first input; in response to the first input, displaying the second interface, where at least the object in the first video is displayed on the second interface The first identification corresponding to the sounding object, and the first control corresponding to the first identification; in response to the second input to the target first control in the second interface, playing the first video that masks the sound of the target sounding object, wherein the first An input is an input for the second identification on the first interface or the first input is an input for the target sounding object in the first interface. The embodiments of the present invention can shield specific sounds during video playback, so as to improve user experience in watching videos.

The invention discloses a mobile terminal video stream stealth transmission method based on the Android platform. The method comprises the following steps: scrambling a confidential letter to be hidden to obtain a chaotic confidential letter sequence; selecting an image block with complex vein, large movement component and suitable for information hiding as a to-be-embedded carrier; extracting confidential letter bits from the chaotic confidential letter sequence in groups, performing xor operation on 4 intermediate frequency coefficients in all image block DCT quantization coefficients with marks and sizes of 8*8 pixels to form video compressed encoding stream containing stealth; and restoring the confidential letter from the video compressed encoding stream by a receiver by using a negotiation key. Execution efficiency of the method is considered while ensuring the security, the stealth effect is good, the flexibility is high, and the stealth communication demands of the mobile terminal are satisfied.

The invention discloses a live recording and broadcasting method for synchronously transmitting MIDI based on the RTMP protocol. Firstly, by collecting images, audio and MIDI signals, and encoding and compressing the collected images and audio respectively; secondly, compressing the collected MIDI signals and encoding The audio is mixed, and the encoded and compressed images are pushed to the server together, and the encoded and compressed images, mixed audio and MIDI signals are recorded and broadcasted at the same time; then, based on the RTMP protocol, the mixed audio and MIDI signals are pulled from the server and separated. MIDI data, decode audio data and image data at the same time; then, integrate the decoded image data and audio data into playback audio and video, and send the separated MIDI data to the musical instrument; finally, realize the synchronous linkage between audio and video playback and musical instruments . Based on the RTMP protocol, the invention transmits MIDI, audio, and images synchronously and saves the MIDI data after transferring to M3U8. The live recording and broadcasting of musical instruments can be realized, and users can also choose live broadcasting or recording broadcasting according to needs, which has strong applicability.

The invention discloses a projection device and a trapezoidal correction method thereof. The projection device includes a detection module, an image capture device, a processing module and an image correction unit. The detection module is used to obtain the first plane where the target object is located and the projection The first distance of the device and the installation position of the projection device, the image capture device is used to identify and track the target object, and acquire an image with the target object when the target object is in a stable state, and the processing module is used to store the target object The first distance and the installation position, and analyzing the image, the image correction unit is used to perform trapezoidal correction on the picture, wherein the processing module obtains the target object and the optical axis according to the first distance, the installation position and the image The second distance of the second plane where the optical axis is located and the third distance from the third plane where the optical axis is located, and the corresponding correction value is obtained according to the second distance and the third distance, and then the picture is processed according to the correction value Keystone correction.

The invention provides a network terminal playing control method based on an AES (Advanced Encryption Standard) and material verification. Specific to the aim of ensuring the integrity and the uniqueness of playlists and material files, a network terminal is required to decrypt and verify whether the playlists and played materials are transmitted by a platform side or not before using the playlists every time, and is only used for playing the material files transmitted by the platform side. Small materials such as html (htm) files, playlist xml files and txt text files can be verified and operated fully; and if verification and full-text operation are applied to large materials such as picture files and video files, the processing time of the network terminal is occupied to a large extent, and the overall playing performance of the network terminal is lowered. According to the method, large materials are processed by adopting a method for extracting certain positions of the materials and calculating verification values with a CRC32 (Cyclic Redundancy Check 32) algorithm, so that the encryption and decryption time of the network terminal can be shortened, and the integrity and the uniqueness of the material files can be ensured.

Embodiments of the present application provide a playback processing method, device, device, and storage medium, so as to perform operations during normal playback. The method includes: during the process of playing video data, acquiring prompt information according to a trigger point corresponding to the video data; displaying the prompt information; receiving a response operation corresponding to the prompt information, and when the response operation satisfies the set After setting the conditions, change the display of the setting content. The terminal device can perform operations without affecting the normal playback of video data.

The invention provides a novel playing list displaying method. The method comprises: at least one micro player is embedded into a play list displayed at a player interface, wherein the micro player is used for displaying a content that is being played by the player synchronously and a playing progress bar in the micro player carries out displaying with the progress of the played content; and when the content that is being played at the player interface is in a pause, fast-forward, or fast-backward state, the content that is played synchronously in the micro player is displayed in a pause, fast-forward, or fast-backward state correspondingly, wherein the content t that is being played by the micro player does not output the sound of the content. Therefore, the played content in the current player is obtained by the micro player in the play list, so that the watching experience of the user is improved.

The invention discloses a control processing method for a video player and a video player client. The video player is updated automatically when the video player is used for playing videos. The method comprises the following steps: when that a user starts the video player and connects the video player to a network to run is detected, playing video streams in the video player according to a video playing instruction, and carrying out a first step and a second step in a process of playing the video streams, wherein the first step comprises: acquiring a program package latest version number corresponding to the video player from a network operation server, and judging whether a program package which is called currently by the video player is a latest-version program package or not according to the program package latest version number, and the second step comprises: downloading the latest-version program package from the network operation server if the program package which is called currently by the video player is not the latest-version program package; and after the end of video stream playing, replacing the program package which is called currently by the video player with the downloaded latest-version program package.
