 +===== Minutes of Meetings ===== 
 +==== July 13, 2017 ==== 
 +  * Export Camera Parameters to users : http://​discuss.px4.io/​t/​mavlink-camera-api-discussion/​3278 
 +    *As using json resulted in complexity in defining rules, camera definition will switch to xml format 
 +    *Different cameras in the system to be addressed using different component ID, camera ID to go 
 +    *Mavlink messages to get/set camera param along with possible acks discussed & defined. 
 +    *Existing storage related mavlink messages to be used with camera comp id to target camera storage. 
 +  * Video Stream discovery over MAVLink : https://​github.com/​mavlink/​qgroundcontrol/​pull/​5271 
 +    *Discussion to continue on the PR 
 + 
 +==== July 5, 2017 ==== 
 +  * Scope/​Roadmap : 
 +    *Scope for discussion be kept minimal to stay focused. 
 +    *Roadmap will be prepared soon 
 +  * Export Camera Parameters to users : http://​discuss.px4.io/​t/​mavlink-camera-api-discussion/​3278 
 +    *Had a detailed discussion on the protocol and its various aspects 
 +    *Everyone has agreed to the Gus’s proposal, implementation to follow 
 +    *Discussed and agreed on the MAVlink messages to be used. 
 + 
 +==== Jun 28, 2017 ==== 
 +  * Roadmap : 
 +    *There need to be a roadmap for the camera related activities. 
 +    *Gus would prepare and put it up in the DroneCode Camera-WG section 
 +  * Export Camera Parameters to users : http://​discuss.px4.io/​t/​mavlink-camera-api-discussion/​3278 
 +    *Discussion to continue on the discuss.px4.io forum 
 +    *Existing WIP Mavlink messages for setting camera parameters to be deprecated 
 +    *mavlink.io will be updated with new Mavlink messages and json definition file once finalized 
 +  * Video Stream discovery over MAVLink : https://​github.com/​mavlink/​qgroundcontrol/​pull/​5271 
 +    *Will take up this feature after 3.2 release ( suppose to happen in a week) 
 +    *Need clarity on the mavlink communication between camera daemon (that manages all cameras in drone & runs on the companion board) and QGC. Otavio will open an issue in QGC to get inputs 
 +  * Camera related User Interface:​ 
 +    *There is some work ongoing to revamp the UI by Gus 
 +    *Need to collaborate 
 + 
 +==== 21st Jun, 2017 ==== 
 + 
 +  * Regular Weekly Meeting : Every Wednesday after PX4 dev call 
 +    *I will check  on how to schedule a meeting and then send out the meeting invite. 
 +    *Agenda for the meeting to be published a day before. Let me know if anything needs to added to the agenda. 
 +  * Video Stream discovery over MAVLink : https://​github.com/​mavlink/​qgroundcontrol/​pull/​5271 
 +    *There is a PR open for review that implements the MAVLink messages for video stream discovery/​start/​stop on QGC 
 +    *Gus will review and provide inputs 
 +    *Two key things to discuss on the PR  
 +      *The way QGC communicates (Heartbeat messages with unique sys-id and camera comp-id) with Drone over MAVLink for the usecase 
 +      *User interface (Video Streaming Widget)  
 +  * Export Camera Parameters to users : http://​discuss.px4.io/​t/​mavlink-camera-api-discussion/​3278 
 +    *There is proposal on how the camera parameters can be exported ​ by the drone to the GCS and eventually to the user. 
 +    *Everyone need to review and provide inputs 
 +    *Key thing to focus on – 
 +      *Content of the JSON definition file 
 +      *For a given usecase involving def file, sequence of specific MAVLink messages that will be sent & received. 
 +  * Support Multiple Video Stream : https://​github.com/​mavlink/​qgroundcontrol/​issues/​5260 
 +    *There is a proposal by Gus to support multiple video streams on QGC 
 +    *Gus is working on this feature 
 +    *3 things that needs to be addressed to support this feature – 
 +      *Enable QGC to instantiate multiple VideoReceivers,​ each for one video stream (PR merged #5318) 
 +      *Implement/​Invoke MAVLink messages to start/stop multiple streams 
 +      *Add changes to the user interface 
 +  * Camera/​Video User Experience : https://​github.com/​mavlink/​qgroundcontrol/​issues/​5316 
 +    *There is an issue with the way how/where the video source & settings are selected 
 +    *There is a PR that addressed ​ the issue by implementing a Widget #5271 
 +    *Need to finalize on the final UI, perhaps after (3) & (4) 
 +  * Documentation : https://​mavlink.io/​en/​camera_protocol.html 
 +    *There must only be one place where all the details are published, identified the place as mavlink.io 
 +    *Need to put together the list of camera related MAVLink messages, use cases (image/​video capture, streaming etc.) supported and for a given use case, the sequence of specific MAVLink messages that are exchanged.
