Preparation of warm inputs for digital content streaming
Systems and methods, to efficiently prepare for live and stored file content, implement one or more warm inputs, which actively ingest and demux content, but do not actively decode the content until an input switch is commanded. Each warm input can cache a most recent instantaneous decoder refresh and subsequent reference frames (I-frames and P-frames). Upon an input switch being commanded, the subject input commences decoding of such preserved frames. The formerly-warm input then acts as a hot input (decoding every frame) until the input switch completes. The use of warm inputs, which avoid the decoding stage, reduces computational resource use, allows preparation of all inputs by default, and permits metrics, status reports, and thumbnails to be generated regarding non-active inputs.
LOW LATENCY CONTENT DELIVERY
The invention provides a method of media content delivery, where the time taken to deliver each chunk of content is measured, from which the stability or consistency of delivery times are calculated. The amount of data buffered at the user's device awaiting decoding and play-back can then be adjusted (such as by playing out the content slower or quicker), in order to achieve a good compromise between continuous play-out and low end-to-end delay, taking into consideration the current network characteristics.
MULTIMEDIA RESOURCE PROCESSING
A computer-implemented method for processing a multimedia resource, an electronic device and a storage medium are provided. The method includes: sequentially performing decoding processing on a plurality of pictures in a multimedia resource, for each of the plurality of pictures to be decoded, the decoding processing includes: decoding the picture to be decoded to generate a picture to be rendered; placing the picture to be rendered to a rear of a buffer queue; performing rendering processing on one or more pictures to be rendered in the buffer queue, the rendering processing includes: taking out a picture to be rendered at a front of the buffer queue; rendering the picture to be rendered; and the sequentially performing decoding processing on a plurality of pictures to be decoded in the multimedia resource and the performing rendering processing on one or more pictures to be rendered in the buffer queue are executed concurrently.
VIDEO PROCESSING METHOD AND APPARATUS AND TERMINAL DEVICE
A video processing method, apparatus and a terminal device are provided, which relate to the field of video processing technologies. The method includes: when detecting in a video recording process that a user enables a video editing function, presenting a recorded original video stream in a form of a video frame; determining a to-be-edited video frame based on a video frame selection operation that is performed by the user on the video frame; performing video editing on the to-be-edited video frame based on a video frame editing operation input by the user, to generate an edited video stream; and generating a target video stream based on the edited video stream and the original video stream. According to this application, live video editing flexibility can be improved.
Systems and methods for managing content distribution to an in-transit media system
Systems and methods for dynamically multiplexing requested linear media channels and network data on forward link traffic streams of a communication link to a craft media delivery system are provided. Furthermore, systems and methods for receiving dynamically multiplexed requested linear media channels and network data on forward link traffic streams of a communication link by a craft media delivery system are also provided.
Live video broadcast method, live broadcast device and storage medium
The present disclosure provides a live video broadcast method performed by a first mobile device. The method includes: receiving a live broadcast command to live broadcast a video game played by a user on the first mobile device, and creating a video buffer for the video game based on the live broadcast command; binding the video buffer with a game engine to detect and extract video picture frames from the video game and store them in the video buffer; transferring the video picture frames into a frame buffer to be displayed on the first mobile device; collecting voice data by using a microphone, and synchronously synthesize the voice data and the video picture frames stored in the video buffer into a video streaming media file; and uploading the video streaming media file to a live broadcast server so as to perform live broadcasting of the video game to other devices.
System and process for synchronized media play
Embodiments include processes for media object rendering, including the steps of providing a plurality of clients, the clients including a media client and the clients in communication with a synchronization client, the clients defining a synchronization group. The media clients include instructions for receiving media object content over a network from a content server, rendering the media object content, and random access to the media object content in response to synchronization client seek time instructions. The synchronization client includes instructions to calculate a relative lag and provide seek time instructions to the media clients for a media object being rendered, the relative lag being a running measurement of its offset relative to the synchronization server's clock. The synchronization client periodically queries the clock of a synchronization server. The synchronization server responds to the synchronization client queries with internal clock value as a timestamp and a timestamp for a target time reference within said media object content for the synchronization group, whereby the synchronization client provides seek time to its paired media clients for the media client to move to that offset, establishing and maintaining playback synchronization among the synchronization group.
SIGNAL PROCESSING DEVICE AND IMAGE DISPLAY DEVICE COMPRISING SAME
An image display apparatus including the same are disclosed. A signal processing device of the present disclosure includes a decoder to decode data encoded based on at least two different coder-decoders, a buffer memory, and a controller to control the decoder and the buffer memory, wherein the controller controls the decoder to divide the buffer memory into a first storage space and a second storage space based on a codec change signal being received, and manages input or output of data of the first and the second storage space in parallel or simultaneously. Accordingly, it is possible to change codecs in real time without delay when codec change is required and to provide content without interruption of a screen to a user.
Data processing method and apparatus, electronic device, system, and storage medium
A data processing method and apparatus, and an electronic device, a system and a storage medium are provided. The method is applicable to a main thread in a Web client and includes: obtaining audio and video data of a target video from a server decapsulating the obtained audio and video data to obtain first audio and video data; sending the first audio and video data to a target sub-thread in the Web client, so that the target sub-thread decodes the first audio and video data to obtain second audio and video data and sends the second audio and video data to the main thread; receiving the second audio and video data sent by the target sub-thread; and rendering video data in the second audio and video data by using a rendering module of a browser of the Web client, and taking the rendered video data and audio data in the second audio and video data as to-be-played data for the target video. The technical solution according to the embodiment of the present application allows a Web client to play audio and video data without browser plug-ins.
Method for playing a plurality of videos, storage medium and computer device
Provided is a method for playing a plurality of videos, including: creating a sliding window with a preset length according to a first to-be-played video in the plurality of videos, wherein the sliding window comprises the first to-be-played video and a preset number of second to-be-played videos; preloading each video in the sliding window by each of video players; preloading the first to-be-played video by one of the video players and playing the first to-be-played video as a currently playing video, wherein the second to-be-played videos are preloaded by other video players; and playing one of the second to-be-played videos by calling a video player interface corresponding to the second to-be-played video in the sliding window in response to the currently playing video being switched to the second to-be-played video.
