@Deprecated
public interface VideoEditingNativeInterface
extends com.codename1.system.NativeInterface

This native interface is deprecated because you shouldn't use it directly.

This native interface provides methods to get some info of the video placed in the FileSystemStorage and to optimize them for fast uploading to a server.

About the video compression, it relies on MobileFFmpeg on Android and on AVAssetExportSession on iOS.

Method Summary

Modifier and Type	Method and Description
void	getImageFromVideo(java.lang.String videoFile, java.lang.String jpegFile) Deprecated. Extract the first frame from the given video file and saves it to the given jpeg file.
int	getVideoBitrate(java.lang.String videoFile) Deprecated. Get the average bitrate (in bits/sec), if available.
long	getVideoDuration(java.lang.String videoFile) Deprecated. Returns the duration of the videoFile in seconds, or -1 in case of error
java.lang.String	getVideoSize(java.lang.String videoFile) Deprecated. Returns the size of the given video in the format widthxheight, for example 1280x720
void	optimizeVideoForUpload(java.lang.String inputVideoFile, java.lang.String outputVideoFile) Deprecated. (Async) method to optimize the given inputVideoFile for fast uploading.Currently it uses a default low quality both on Android and iOS.
