006    /**
007     * This class contains basic video control functionality for live conversations with video. Basically, Video objects represent specific Participant's video state in a live Conversation. The Video class can represent both local (outgoing) and remote (incoming) video streams. Note that as of SkypeKit SDK version 3.2, this class no longer handles video rendering in the UI. Currently available SkypeKit runtimes do not support multi-party video. The API however is designed with future compatibility in mind, so the Video class is attached to Participant class rather than Conversation class. Once multi-party video will become available for SkypeKit, the logic should go like this: <br><br>Let there be 4-way live conversation C and participants P1, P2, P3 and P4. P1 is the local user. Remote participants P2 and P3 are capable of sending video. Remote user P4 is not capable of sending video. You would then end up with 4 video objects: V1, V2, V3 and V0. <br><br> - C->P1->V1-> outgoing video stream <br> - C->P2->V2-> incoming video stream 1 <br> - C->P3->V3-> incoming video stream 2 <br> - C->P4-> no video object as participant P4 does not advertise supporting video <br> - V0-> local webcam preview - this is not attached to any particular conversation, however the corresponding video object can be retrieved with Skype.GetPreviewVideo method. <br><br>As getting from a live conversation to running video streams involves three classes, it can be somewhat less than obvious. The basic state transition logic goes like this: <br><br>You start out with a Conversation, that suddenly becomes live <br><br>CONVERSATION.LOCAL_LIVESTATUS = IM_LIVE <br>At this point you have access to participant list of that conversation. The next step will be to catch Partcipant property changes for PARTICIPANT.VIDEO_STATUS to see if any of the people in conversation have Video available. Note that you should not make assumptions on when this availability happens. Remote users may switch their video on-off as they please. <br><br>PARTICIPANT.VIDEO_STATUS = VIDEO_AVAILABLE <br>If you get to VIDEO_AVAILABLE (not necessarily for all Participants), you can retrieve Video object, with Participant.GetVideo method. <br><br>Now you will need to handle Video.STATUS property changes. In case of successful video call, the sequence of Video.STATUS and Participant.VIDEO_STATUS changes for each Participant and Video object should look like this: <br><br> - Video.STATUS = AVAILABLE <br> - Video.STATUS = STARTING <br> - Video.STATUS = CHECKING_SUBSCRIPTION <br> - Video.STATUS = STARTING <br><br>Participant.VIDEO_STATUS = VIDEO_CONNECTING <br> - Video.STATUS = RUNNING <br> - Participant.VIDEO_STATUS = STREAMING <br>Both Video.STATUS == RUNNING and Participant.VIDEO_STATUS == STREAMING are indicative that the video for that particular participant is up and running, and your UI should update itself accordingly. <br><br>NB! Note that it is not enough to check for Video.STATUS property updates. By the time you obtain the Video object in your client, it may already it may already have progressed to a further status. You should always check the status property immediately after obtaining the Video object. <br>
