Type Function Library media.* Return value none Revision Release 2022.3683 Keywords media, camera, video See also media.hasSource()
Opens a platform-specific interface to the device's photo library. This function is asynchronous, meaning that it returns immediately so the calling code will continue to execute until the end of its scope; after that, the application will be suspended until the session is complete.
This API is not supported on Windows, macOS, or tvOS.
plist
table of build.settings
. When the system prompts the user to allow access, the associated description is displayed as part of the alert. Note that these descriptions can be customized to your preference and they can even be localized (guide).settings = { iphone = { plist = { NSPhotoLibraryUsageDescription = "This app would like to access the photo library.", }, }, }
origin
and permittedArrowDirections
to specify the location and direction of the popup used to select the video.media.selectVideo ( { listener [, mediaSource] [, origin] [, permittedArrowDirections] } )
Listener. Can be either a function listener or a table listener. If a table, it must have a completion method. The event dispatched to the listener will be a completion event with the following additional properties:
event.url
is a string which is the URL of the video. If the operation was cancelled, this value will be nil
.event.completed
will be true
if the user captured a video; false
if the user cancelled the video selection.event.duration
will be the number of seconds of the video if the user selected a video; nil
if the user cancelled the video selection or the value could not be obtained. On some Android app/device combinations, this can occur if the android.permission.READ_EXTERNAL_STORAGE
permission is missing.event.fileSize
will be the number of bytes of the user selected a video; nil
if the user cancelled the video selection or the value could not be obtained. On some Android app/device combinations, this can occur if the android.permission.READ_EXTERNAL_STORAGE
