A display control method and an electronic device thereof according to various embodiments include a display, a processor operatively connected with the display, and a memory operatively connected with the processor, and the memory stores instructions that, when executed, cause the processor to execute an application, to detect performance degradation of the application, and to adjust a resolution of the application based on a resolution adjustment cost of the application in response to the performance degradation of the application being detected.

In some embodiments, a method receives playback information for a plurality of representations based on one or more videos being played at a media player. The plurality of representations have at least one different characteristic that affects playback of the video. A dropped-frame measurement is predicted for the plurality of representations based on the playback information. Then, the dropped-frame measurement is compared to a threshold for the plurality of representations. The method marks a first set of the plurality of representations as not being available based on the comparing. A second set of the plurality of representations are provided to the media player when the media player requests a video for playback and the first set of the plurality of representations for the video are blocked from being requested by the media player.

A mobile device executes an application and is remotely controlled by a client device. To reduce bandwidth used during operation, a rate limiter selects a portion of data from the mobile device to be sent to the client device. A timer value is specified. The rate limiter on the mobile device, on an ongoing basis, updates a pointer to the latest data stored in memory, such as a latest frame of an image presented by a display of the mobile device. When the elapsed time since last data sent is greater than or equal to the timer value, the latest data is sent to the client device, and the timer is reset.

Methods, systems, and apparatus, including a media player and computer-readable mediums, are described for rendering media content at a frame rate that is safe to a user. A system, or its media player, obtains media content that includes video content having multiple frames. The system determines a frame rate representing a rate for sequentially displaying the frames to the user when the media player plays the media content. Image content of each frame is scanned and data describing different photosensitivity thresholds is obtained. Based on a photosensitivity of the user, the system determines that one or more frames in a portion of the media content include image content that is unsafe to the user when the media player plays the media content. The system selectively decreases a frame playback rate for the portion of the media content as a function of an input value that is selectable by the user.

Systems, methods, and software described herein manage the storage of video data in multiple storage locations. In one example, a system obtains video data from a video source and stores the video data in a first format in a first storage location. Additionally, the system stores the video data in a second format in a second storage location, wherein the second format comprises one or more lesser video quality characteristics than the first format. The system further identifies metadata associated with the video data and stores the metadata in the second storage location.

A device may be configured to receive video data including a sequence of frames. The sequence of video frames may have a high frame rate. Frames within the sequence of frames may be modified according to multiple fractional frame rates.

Disclosed is a method and apparatus for adjusting a playing speed of a video. The method for adjusting a playing speed of a video includes: after detecting a playing speed adjustment instruction of a target video, determining a target playing speed corresponding to the playing speed adjustment instruction; determining an initial frame rate of the target video, and taking the product of the initial frame rate and the target playing speed as a target parameter of the target video; processing the target video based on a preset frame number adjustment rule corresponding to a target comparison relationship; and adjusting timestamps of video frames contained in the processed target video, based on the preset target frame rate, so that the adjusted target video is played in the preset target frame rate. By applying the present solution, the adjusted target video can be played in the preset target frame rate, thus improving the display quality of the video whose playing speed has been adjusted, and improving the user experience.

Methods, apparatus, systems and articles of manufacture to generate temporal representations for action recognition systems are disclosed. An example apparatus includes an optical flow computer to compute first optical flows for a video based on computing differences between pairs of frames of the video; an evolution of trajectories (EoT) generator to generate EoT temporal representations of the video based on (a) computing second optical flows of the video and (b) aggregating ones of the second optical flows having different time spans; an action identifier to: identify first actions in the video based on the first optical flows; identify second actions in the video based on the EoT temporal representations; and identify third actions in the video based on frames of the video; and a fuser to determine a fourth action based on a weighted average of the first actions, second actions, and third actions.

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 a 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.
