Video stream customization using graphics

A computer-implemented method comprising:

• receiving, by a server of an online system, an image from a client device of a user of the online system;
• determining user information of the user based on actions performed by the user stored in the online system;
• identifying a plurality of graphics provided at least in part by a plurality of users of the online system;
• determining a set of candidate graphics by filtering the plurality of graphics based at least in part on the user information of the user;
• for each graphic of the set of candidate graphics, generating a score for the graphic indicating a likelihood of the user selecting the graphic;
• providing, by the server to the client device, the set of candidate graphics for presentation to the user on the client device in an order based on the scores;
• receiving, by the server from the client device, a selection for a candidate graphic of the set of candidate graphics;
• and
• providing, by the server to the client device, a composite view generated by combining the selected candidate graphic with the image for presentation to the user on the client device.

A non-transitory computer-readable storage medium storing instructions that when executed by a processor cause the processor to perform steps including:

• receiving, by a server of an online system, a video stream from a client device of a user of an online system;
• determining user information of the user based on actions performed by the user stored in the online system;
• identifying a plurality of graphics provided at least in part by a plurality of users of the online system;
• determining a set of candidate graphics by filtering the plurality of graphics based at least in part on the user information of the user;
• for each graphic of the set of candidate graphics, generating a score for the graphic indicating a likelihood of the user selecting the graphic;
• providing, by the server to the client device, the set of candidate graphics for presentation to the user on the client device in an order based on the scores;
• receiving, by the server from the client device, a selection from the user for a candidate graphic of the set of candidate graphics;
• and
• providing, by the server to the client device, a composite view generated by combining the selected candidate graphic with the video stream for presentation to the user on the client device.
