Disclosed is a system and method for reducing the total latency for transferring a frame from the low latency camera system mounted on an aerial vehicle to the display of the remote controller. The method includes reducing the latency through each of the modules of the system, i.e. through a camera module, an encoder module, a wireless interface transmission, wireless interface receiver module, a decoder module and a display module. To reduce the latency across the modules, methods such as overclocking the image processor, pipelining the frame, squashing the processed frame, using a fast hardware encoder that can perform slice based encoding, tuning the wireless medium using queue sizing, queue flushing, bitrate feedback, physical medium rate feedback, dynamic encoder parameter tuning and wireless radio parameter adjustment, using a fast hardware decoder that can perform slice based decoding and overclocking the display module are used.

In some implementations, a computer-implemented method includes obtaining a video that includes a plurality of tracks. The method further includes determining whether a partial transcoded file is available that corresponds to the video. The method further includes, if the partial transcoded file is available, obtaining a timestamp associated with the partial transcoded file, transcoding a portion of the video that begins at the timestamp associated with the partial transcoded file, and combining the partial transcoded file and the transcoded portion of the video to generate an output video. The method further includes, if the partial transcoded file is not available, transcoding the video from a start of the video using the transcoder to obtain a plurality of output tracks and combining the plurality of output tracks to obtain the output video.

Aspects of the present disclosure involve systems and methods for performing operations comprising receiving, with a messaging application, user input to access a graphical image modification feature of the messaging application; in response to receiving, causing display of a video; accessing a first configuration rule of a plurality of configuration rules that associates a first device property rule with the graphical image modification feature of the messaging application; determining that the first configuration rule is satisfied by a first property of the client device; and in response to determining that the first configuration rule is satisfied by the first property of the client device, causing display of a first plurality of graphical image modification options each associated with performing a different modification to the video.

This method for delivering a multimedia content, said multimedia content including at least one second content, includes, during the rendering of the multimedia content, detecting a start of the second content, performing a fast-forward with a controlled speed during the rendering of the second content, in which the speed is controlled such that at least one representative frame of the second content is completely rendered, detecting an end of the second content, and stopping the fast-forward.

A computing system identifies a media stream being received by a client, based on fingerprint matching conducted with query fingerprints generated by the client at a frame rate. The computing system then causes the client to increase the frame rate, in order to facilitate establishment by the computing system of synchronous lock between true time within the media stream and client time according to an clock of the client. The computing system then uses the established synchronous lock as a basis to map a true-time point at which a content revision should be performed in the media stream to a client-time point at which the client should perform the content revision. And the computing system causes the client to perform the content revision at the determined client-time point.

The present disclosure provides a method and apparatus for automatically synchronizing a first stream of media data with a second, and outputting a third by decoding the streams into channels, splitting the channels into a plurality of piecewise segments defined by control points that the control points with the same index are to be synchronized in time across all the channels, automatically and intelligently adjusting the length of the media data in each segment in an optimal and hybrid manner using a linear or non-linear digital signal processing algorithm, synchronizing and mixing all the processed segments, and outputting the final mixed and encoded data stream. Specifically, one of the media data is video and the other is audio or a translation voice in a different language. With a controlled minimized distortion, one can achieve faster post-processing speed and optimal synchronization quality, therefore save both time and cost for video language localization services.

The present application provides a video frame transmission method, apparatus, electronic device, and readable storage medium, and relates to the field of Internet of Vehicles, comprising: transmitting a first video frame of a target video to a target device at a reference frame rate; acquiring time delay of the first video frame; determining, according to the time delay, target frame rate of a second video frame to be transmitted in the target video; transmitting the second video frame to the target device at the target frame rate. By dynamically adjusting the transmission frame rate of the video frame in the method, the time delay of the video frame from creation to display on the target device is reduced, thereby ensuring the presentation effect of the video on the target device.

An apparatus and method for editing an image including dynamic tone metadata in an electronic device are provided. The electronic device includes a display, and at least one processor operatively connected to the display, wherein the at least one processor may be configured to generate a third image to be inserted between a first image and a second image continuous with the first image among a plurality of images belonging to video content, generate dynamic tone metadata of the third image based on dynamic tone metadata of the first image and the second image, and update the video content by adding the third image and the dynamic tone metadata of the third image.

An image data of pictures constituting moving image data is encoded to generate an encoded video stream. In this case, the image data of the pictures constituting the moving image data is classified into a plurality of levels and encoded to generate a video stream having the image data of the pictures at the respective levels. Hierarchical composition is equalized between a low-level side and a high-level side, and corresponding pictures on the low-level side and the high-level side are combined into one set and are sequentially encoded. This allows a reception side to decode the encoded image data of the pictures on the low-level side and the high-level side with a smaller buffer size and a reduced decoding delay.

Systems and methods for bandwidth-limited video transport are configured to receive (or otherwise discern) a selection of video parameter limits that correspond to a bandwidth limit and apply the video parameter limits to an input video stream to enforce the bandwidth limit while preserving video quality. Methods may include adjusting the video stream one parameter at a time until the adjusted video stream meets the bandwidth limit. Parameters to be adjusted may include image resolution, frame rate, image compression, color depth, bits per pixel, and/or color encoding. In some embodiments, the image resolution is reduced first, the frame rate is reduced next, and the image compression is increased last. The extent and/or order of the adjustments of the parameters may be selected by the user, based on the content of the video stream, and/or based on the bandwidth limit.
