Hello, you can use this video player available in the Mendix app store.
A sample app is also available: https://videoplayer-sandbox.mxapps.io
Play video by uploading a file:
1) You need to upload a file in form of File Document. Refer to Working with images & files section of documentation to get an idea how to upload a file
2) Use File Document Viewer widget to view/play your video. This widget will work inside a data view, the data view should receive object of FileDocument which has the video stored in database.
I have a video in a local PC. Could you show me how to add that video to video player?
