Simple video App for MacOS

General objective: - Provide a simple macOS application to play a camera and blend with one video at background. Requirements: - Programmer must have experience with video libraries (AVFoundation). - Latency of the resulting live video must be zero or minimum. - All sources must be delivered when finished in Xcode files. - Due date is february 28th (or before). - Graphic design is not required. - Swift is prefered as programming language. General description Application will be used for an event where people will perform in front of a camera. In a room with green background, there will be a camera and a monitor connected as second screen to a MacPro. An operator in front the main monitor of the MacPro observes the action of the camera. Then he press "start" to play a video clip. This video clip is then mixed (chroma key) with the camera stream so that the person now sees himself acting within a video clip. After several seconds, the resulting video starts recording until the end of the video clip. Only the audio of the video clip will be recorded. Set up of green background will be similar to this: [login to view URL] Specific required programming tasks: Before loading interface: 1) Read config file with - MySQL Database access data: name, login, paswword. - Value for "chroma key color". - Value for "videoclip folder path". - Value for "waiting time for recording" (in seconds) 2) Read MySQL "player" table - "player_id", "name", "videoclip_id" and "video_recorded". 3) Read MySQL "videoclip" table - "videoclip_id", "filename", "artist" and "description". On running interface: 1) Show a 3 rows table with next 3 players read in MySQL table with and "X" for deleting player from database. 2) Show two buttons: one for playing videoclip choosen by next player, and other to stop it. 3) Connect to camera and show it live in two places: - A preview in the main application with size 640x360. - An independent window of 1280x720. This window must be able to get full size because it will be projected in a second monitor connected. 4) When play button is pressed, selected videoclip starts playing and blending by chroma key with camera streaming. After "waiting time for recording", resulting video (camera video + videoclip video + videoclip audio) is recorded until the end of videoclip playing. 6) Resulting video is saved with a consecutive number filename and MySQL "video_recorded" is filled with video number. 7) Application is refreshed and shows next person in the list.
