Aspects relate to an image signal processor that processes frames at changing frame rates. An example method includes receiving, by an image signal processor, a first sequence of image frames from an image sensor at a first frame rate, processing each image frame of the first sequence of image frames at the first frame rate, and receiving from the image sensor an indication of a frame rate change from the first frame rate to a second frame rate. The method also includes configuring one or more filters of the image signal processor to process image frames from the image sensor in response to receiving the indication of the frame rate change from the image sensor, receiving a second sequence of image frames from the image sensor at the second frame rate, and processing each image frame of the second sequence of image frames at the second frame rate.

Systems, methods, and non-transitory computer-readable media can determine context information associated with a media content item accessible to a user. One or more segments of the media content item can be determined. At least one segment of the media content item to be provided for presentation and a playback speed for the at least one segment can be determined based at least in part on a machine learning model that evaluates the context information and the one or more segments.

Techniques for enabling the display of video content is a specified display mode, such as the Ultra-High Definition Alliance Specified Reference Mode (UHDA-SRM). A video source device receives video content as a bitstream in one format that includes a specification of a display mode for the video content. The video source also receives information from a display device or other video sink on the display modes that it supports. If the display device supports the specified display mode, the video provides the video content to the display in a second format, such as HDMI, as a series of frames the specification of the display mode embedded in a blanking interval in each of the frames.

Provided are a method, apparatus and device for adding a video special effect and a storage medium. The method includes: acquiring a source video sequence and at least one special effect video sequence; in the case where frame rates of the two or more than two special effect video sequences are same, inserting a frame into the source video sequence and superimposing the two or more than two special effect video sequences on the source video sequence at the same time; and in the case where frame rates of the two or more than two special effect video sequences are different, determining a target frame rate from the frame rates of the two or more than two special effect video sequences inserting frames into the source video sequence and then superimposing the two or more than two special effect video sequences on the source video sequence.

The present disclosure provides a buffer processing method, apparatus, device and computer storage medium, where the method comprises: if it is detected that a drop of an available bandwidth of a receiving terminal exceeds a preset first threshold, detecting whether a drop of a video frame rate of the receiving terminal exceeds a preset second threshold, the second threshold being smaller than the first threshold; if YES, adjusting a buffer size of the receiving terminal; and if NO, keeping the buffer size of the receiving terminal unchanged. The manner provided by the present disclosure can optimize the buffer of the receiving terminal and reduce the delay.

Implementations described herein relate to methods, devices, and computer-readable media to transcode a video. 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.

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.

There are provided methods and devices for media processing, comprising: providing at least one media asset source selected from a media asset sources library, the at least one media asset source comprising at least one source video, via a network or client device; receiving via the network or the client device a media recording comprising a client video recorded by a user of the client device; parsing the client video and the source video, respectively, to a plurality of client video frames and a plurality of source video frames; identifying at least one face in at least one frame of the plurality of source video frames and at least another face in at least one frame of the plurality of client video frames by face detection; superposing one or more markers on the identified at least one face of the plurality of source video frames; processing said client video frames to fit the size or shape of said source video frames by using said one or more markers; concatenating said processed client video frames with said source video frames, wherein said concatenation comprises matching the frame rate and resolution of the processed client video frames to the frame rate and resolution of the plurality of client video frames to yield a mixed media asset.

A method of controlling playback of video content on video player on an electronic computing device, the method includes: automatically playing a video content or playing the video content when a user selects the content; detecting a user interaction on a touch-sensitive interface, wherein said user interaction comprises one or more of: a static hold interaction and/or a drag interaction; in response to said user interaction, the video player rewinding or fast-forwarding a video content; and in response to detecting cessation of the interaction, the video player starting to play back the video content at normal speed.

Various embodiments of methods, apparatus, systems, and non-transitory computer-readable storage media for buffer recovery in segmented media delivery applications are described. Segments of a live media presentation are stored in a buffer. A number of segments in the buffer is determined to have fallen below a threshold. Based on that determination, various buffer recovery techniques may be performed. In one such technique, a buffered segment is decoded into a first set of video frames, the first set of video frames having a first playback duration. The first set of video frames is encoded into a second set of video frames having a second playback duration that is longer than the first playback duration.
