Providing video to subscribers of a messaging system

Abstract

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing a video to subscribers of a messaging system. A method includes obtaining a live video stream generated by a video source. The method also includes publishing one or more messages including one or more frames of the live video stream to a first channel of a plurality of channels. The video source is associated with the first channel.

What is claimed is: 
     
         1 . A method, comprising:
 receiving a video stream generated by a video source; and   publishing, by a computer processing device, one or more messages comprising one or more frames of the video stream to a channel of a plurality of channels of a publish-subscribe system.   
     
     
         2 . The method of  claim 1 , wherein the video stream comprises a live video stream. 
     
     
         3 . The method of  claim 1 , wherein the video source is associated with the channel. 
     
     
         4 . The method of  claim 1 , wherein the one or more messages are published to the channel while the video source continues to generate the video stream. 
     
     
         5 . The method of  claim 1 , comprising:
 dividing the one or more frames of the video stream into a plurality of portions, wherein each message of the one or more messages comprises one of the plurality of portions.   
     
     
         6 . The method of  claim 1 , wherein each message of the one or more messages comprises data indicative of one or more of:
 a width of a video frame of the video stream;   a height of the video frame;   a frame type of the video frame; and   a codec of the video frame.   
     
     
         7 . The method of  claim 1 , wherein each message of the one or more messages comprises a video stream identifier that identifies the video stream. 
     
     
         8 . The method of  claim 1 , comprising:
 publishing one or more second messages to a second channel of the plurality of channels, wherein the one or more second messages comprise metadata associated with the video source.   
     
     
         9 . The method of  claim 8 , wherein the metadata comprises one or more of:
 a video source identifier that identifies the video source;   a geographical location of the video source;   an indication that audio is available from the video source; and   a type for the video source.   
     
     
         10 . The method of  claim 1 , comprising:
 receiving, on a second channel of the plurality of channels, a request to filter the one or more messages for a subscriber client;   identifying a subset of the one or more messages based on the request to filter the one or more messages; and   providing the subset of the one or more messages to the subscriber client.   
     
     
         11 . A system, comprising:
 a computer processing device to:
 receive a video stream generated by a video source; and 
 publish one or more messages comprising one or more frames of the video stream to a channel of a plurality of channels of a publish-subscribe system. 
   
     
     
         12 . The system of  claim 11 , wherein the video stream comprises a live video stream. 
     
     
         13 . The system of  claim 11 , wherein the video source is associated with the channel. 
     
     
         14 . The system of  claim 11 , wherein the one or more messages are published to the channel while the video source continues to generate the video stream. 
     
     
         15 . The system of  claim 11 , wherein the computer processing device is further to:
 divide the one or more frames of the video stream into a plurality of portions, wherein each message of the one or more messages comprises one of the plurality of portions.   
     
     
         16 . The system of  claim 11 , wherein each message of the one or more messages comprises data indicative of one or more of:
 a width of a video frame of the video stream;   a height of the video frame;   a frame type of the video frame; and   a codec of the video frame.   
     
     
         17 . The system of  claim 11 , wherein the computer processing device is further to:
 publish one or more second messages to a second channel of the plurality of channels, wherein the one or more second messages comprise metadata associated with the video source.   
     
     
         18 . The system of  claim 17 , wherein the metadata comprises one or more of:
 a video source identifier that identifies the video source;   a geographical location of the video source;   an indication that audio is available from the video source; and   a type for the video source.   
     
     
         19 . The system of  claim 17 , wherein the computer processing device is further to:
 receive, on a second channel of the plurality of channels, a request to filter the one or more messages for a subscriber client;   identify a subset of the one or more messages based on the request to filter the one or more messages; and   provide the subset of the one or more messages to the subscriber client.   
     
     
         20 . A non-transitory computer-readable medium having instruction stored thereon that, when executed by a computer processing device, cause the computer processing device to:
 receive a video stream generated by a video source; and   publish, by the computer processing device, one or more messages comprising one or more frames of the video stream to a channel of a plurality of channels of a publish-subscribe system.
