A method for operating a messaging system is provided. The method is adapted to send and receive modifiable videos and includes receiving, by a computing device, a first authorization from a user to use a self-image of the user in a personalized video. The method also includes receiving, by the computing device, a second authorization from the user to enable use of another self-image of another user in the personalized video. The method further includes sending, by the computing device, after the first and second authorizations have been received, the personalized video including at least part of the self-image of the user, at least part of the other self-image of the other user, and at least part of a stock video. A system and a non-transitory processor-readable medium for operating a messaging system adapted to send and receive modifiable videos are provided.

A data stream having volumetric video data encoded therein in a scene description language, the data stream representing a scene comprising one or more objects is disclosed, wherein the data stream comprises for at least one object first mesh data, second mesh data and correspondence information, wherein the first mesh data describes the at least one object with a first mesh, the second mesh data describes the at least one object with a second mesh, and wherein the correspondence information indicates a mapping between the first and second mesh. Devices, Methods and a computer program product are also described.

A method of accessing 3D media content based on perspective-based random access is provided. The method includes receiving the media content and metadata, wherein the metadata includes first information about a perspective and second information about at least one face onto which the 3D object is projected, and the at least one face is associated with the perspective, and performing the perspective-based random access for the media content based on the first information and the second information.

Disclosed are a method, an apparatus and a smart mobile terminal for editing a video. The method includes: acquiring an editing instruction to be executed of a user; selecting frame images which indicate a duration of a video segment in a preset showing area based on the editing instruction; storing the video segment in a preset second storage area; storing a reserved video segment in a preset first storage area; rendering the frame images by invoking a preset rendering script for highlighting the frame images in the showing area; retrieving frames of the reserved video segment sequentially based on a preset first time span; determining scaled frames based on a preset scaling proportion and the frames; and arranging the scaled frames in the showing area sequentially in an order of retrieving for displaying frame images which indicates a duration of the reserved video segment in the showing area.

According to one aspect of the present disclosure, a transmission method for enabling transmission of content using a broadcast and a communication channel includes: transmitting playback control information and service information using at least the broadcast wave, the service information being information for playing back content transmission using the broadcast and content transmission using the communication channel when the content is transmitted using the broadcast and the communication channel. The service information includes attribute information indicating that the first content data and the second content data constitute the content and location information that indicates a location for acquiring meta-information on playback control of the second content. The playback control information includes indexes of a relationship between the first content data and the second content data.

Techniques are provided for processing media content. For example, a process can include using a scene description for to obtain media information and buffer information for a media object. The media information can identify an expected format for storing the media object in one or more output buffers of a media pipeline. The buffer information can include output buffer attributes. The process can include using the media information and the buffer information to initialize the media pipeline for the media object. The process can include obtaining the media object in a delivery format and generating one or more processed media objects. Each processed media object can be converted from the delivery format to the expected format for storing the processed media object in an output buffer. The process can include outputting the processed media object(s) to the output buffer(s) using the initialized media pipeline.

A self-learning automated application testing system automatically generates test scripts during the execution of an application using an automatic test script generator plugged into the application. The test scripts are generated by capturing event data of events emitted during the execution of the application. The test scripts are compared to the test scripts stored in a test script repository and those test scripts that are determined to be duplicates of the existing test scripts are discarded while the remaining test scripts are stored as new test scripts in the test script repository. An application tester runs regression tests on the application per the new test scripts and logs the results to a test results repository. A dashboard is also provided that enables a user to view and edit the test scripts from the test scripts repository, change configuration settings from a configuration repository, and view test results from the test results repository.

According to one aspect of the present disclosure, a transmission method for enabling transmission of content using a broadcast and a communication channel includes: transmitting playback control information and service information using at least the broadcast wave, the service information being information for playing back content transmission using the broadcast and content transmission using the communication channel when the content is transmitted using the broadcast and the communication channel. The service information includes the content and location information that indicates a location for acquiring meta-information on playback control of the second content. The playback control information includes indexes of a relationship between the first content data and the second content data.

Systems and methods for operating a messaging system are provided. An example method includes receiving an authorization from a user to enable use of a self-image of a further user in a personalized video, sending, in response to the authorization, the personalized video including at least part of the self-image of the further user and at least part of a stock video to a further computing device associated with the further user, and receiving, from the further computing device, an indication of whether the further user has authorized using the self-image in the personalized video. The method includes receiving a text typed by the user, synthesizing a voice reading or singing the text, and adding the voice to the personalized video. The method includes, prior to sending the personalized video, modifying a voice present in the personalized video to match the voice of the user.

A method and apparatus include receiving a timed-metadata track identifying point cloud tiles corresponding to one or more spatial regions within a point cloud scene. A decoding device determines one or more point cloud tiles to be used for rendering an image. One or more geometry tile tracks are retrieved, via a communications network, corresponding to the determined one or more point cloud tiles. Each geometry tile track comprises point cloud geometry data for a respective tile. The retrieved geometry tile tracks are processed
