[FREE] [BETA] Extract image frame from video
This is a simple extension to extract a frame from a video. This extension is still under development so there might be a bunch of bugs :/
This extension is suggested by @eps_prieur: https://community.kodular.io/t/extract-an-image-from-a-video-not-thumbnail/91922
Basically, it generates an image and temporarily stored in the external storage. It will be deleted once the application is stopped (OnDestroy)
Documentation
| Block | Description |
|---|---|
| Error | Raises when any errors occurred |
| GotImage | Raises when an image is extracted by the async method |
| ImageCreated | Raises when images are deleted by the method DeletAllCreatedImagesAsync. |
| GetImageViaPath | Get an image of a video with a given time. Use -1 if you don’t need any option. Path can accept: Absolute path, File URL path, Uri path and URL (direct media link). Return an external path, or “Error” if any error occurred. |
| GetImageViaPathAsync | Does the same as GetImageViaPath but run in an async way. |
| CreatedImages | Return a list of ALL created Images (except the deleted one). |
| DeleteAllCreatedImages | Delete All Created Images. After deletion, the file won’t show up in the CreatedImages list. Files which deletion is failed will stay in the list. |
| DeletAllCreatedImagesAsync | Does the same as GetImageViaPath but run in an async way. |
| DeleteAllOnDestroy | True if you want to delete all on destroy, otherwise false. |
| SavePath | Defining the absolute path to store the created image. (default is the primary shared/external storage directory) |
| Closest, ClosestSync, NextSync, PreviousSync | The constant of options |
For options, here is a detailed documentation:
Documentation
a hint on how the frame is found. Use `OPTION_PREVIOUS_SYNC` if one wants to retrieve a sync frame that has a timestamp earlier than or the same as timeUs. Use `OPTION_NEXT_SYNC` if one wants to retrieve a sync frame that has a timestamp later than or the same as timeUs. Use `OPTION_CLOSEST_SYNC` if one wants to retrieve a sync frame that has a timestamp closest to or the same as timeUs. Use `OPTION_CLOSEST` if one wants to retrieve a frame that may or may not be a sync frame but is closest to or the same as timeUs. `OPTION_CLOSEST` often has larger performance overhead compared to the other options if there is no sync frame located at timeUs. Value is either `0` or a combination of `OPTION_PREVIOUS_SYNC` , `OPTION_NEXT_SYNC` , `OPTION_CLOSEST_SYNC` , and `OPTION_CLOSEST`
