    摘要： Exemplary embodiments relate to the application of coordinated or cooperative effects to a coordinated activity. A coordinated activity protocol is provided for synchronizing interactive effects and experiences across multiple devices. The protocol allows effects to be initiated and coordinated on multiple devices via a real-time communications (RTC) channel. Messages may be exchanged to cooperatively initiate the effect, and (once initiated) generic data may be exchanged via application programming interface (API) calls. According to some embodiments, the coordinated activity is a shared video experience, such as a video conference or shared video-watching experience. According to other embodiments, the coordinated activity relates to other types of experiences, such as single- or multi-player games, shared book reading, communal interactions with a photo album, etc.

    摘要： A first device may receive, from a second device, a reference landmark map identifying locations of facial features of a user of the second device depicted in a reference image and a feature map, generated based on the reference image, representing an identity of the user. The first device may receive, from the second device, a current compressed landmark map based on a current image of the user and decompress the current compressed landmark map to generate a current landmark map. The first device may update the feature map based on a motion field generated using the reference landmark map and the current landmark map. The first device may generate scaling factors based on a normalization facial mask of predetermined facial features of the user. The first device may generate an output image of the user by decoding the updated feature map using the scaling factors.

    摘要： Techniques are described that enable a user to create a collection of content posts on a social networking system. In some cases, a social networking system receives multiple content posts to be shared, and shares the multiple content posts with a first group of user accounts. The social networking system receives a request to create a collection of one or more content posts of the multiple content posts, where the request includes a descriptor associated with the collection. The social networking system generates the collection of the one or more content posts including the descriptor, and provides the collection to a second group of user accounts.

    摘要： Techniques are described herein that enable and assist a user to generate customized video content and alter the video content without altering the customizations. For example, a social networking system may receive, from a user account associated with the social networking system, an input to create video content and add visual customizations to the video content. In some examples, the social networking system may also receive input from the user to alter the video content by altering the length of the video clip and/or adding a second video clip. The social networking system then alters the video content while maintain the previous customizations. The social networking system may then save the altered video content as a draft or share the altered video content to other users on the social networking system.
