## Face effect 玫瑰眼妆 ## Special effects debugging Use xcode to debug special effects in the project, you need to install glfw before use ``` brew install glfw ``` Then use xcode to open```library/src/main/cpp/opengl.xcodeproj```Just Switch effect call code ``` image_process.OnAction("param/blurScreen", 0); ``` ## Automated test - Use [uiautomator2](https://github.com/openatx/uiautomator2) for automatic testing Use as follows: ``` python cd trinity python trinity.py ``` Then use ``` adb devices ``` Just enter the device name in the terminal ## Performance 性能 ## Use Note: The permission judgment is not made in the SDK. The caller needs to apply for permission when using it. The time involved in the SDK is milliseconds. ### Add jcenter dependency ``` gradle dependencies { implementation 'com.github.wlanjie:trinity:0.2.9.1' } ``` ### Load Libraries in Application class ``` companion object { init { System.loadLibrary("trinity") System.loadLibrary("c++_shared") System.loadLibrary("marsxlog") } } ``` ### Permission requirements ``` xml ``` ## Recording ### Configuration parameter - Create a recording preview view ``` kotlin val preview = findViewById(R.id.preview) ``` - Create a recording interface instance ``` kotlin mRecord = TrinityRecord(preview) ``` - Destroy the recording interface instance ``` kotlin mRecord.release() ``` ### Callback settings - Set video rendering callback ``` kotlin mRecord.setOnRenderListener(this) ``` - Set recording progress callback ``` kotlin mRecord.setOnRecordingListener(this) ``` - Set camera callback ``` kotlin mRecord.setCameraCallback(this) ``` ### Open preview - Start preview ``` kotlin mRecord.startPreview() ``` - End preview ``` kotlin mRecord.stopPreview() ``` - Set preview type ``` kotlin // Set the display type // Include crop display, the original proportion is displayed in black mRecord.setFrame(mFrame) ``` ### Recording control / management - Switch camera ``` kotlin mRecord.switchCamera() ``` - Get the current camera ``` kotlin // return the current camera id val facing = mRecord.getCameraFacing() ``` - Switch flash ``` kotlin mRecord.flash(mFlash) ``` - Setting up zoom ``` kotlin // Set the focal length zoom, 0-100 100 is the maximum zoom mRecord.setZoom(0) ``` - Set exposure ``` kotlin // Set the camera exposure, 100 is the maximum exposure mRecord.setExposureCompensation(0) ``` - Manual focus ``` kotlin // Set manual focus, parameters are x and y mRecord.focus(mPointF) ``` - Set the angle of the recorded video ``` kotlin /** * @param rotation Rotation angle includes 0 90 180 270 */ mRecord.setRecordRotation(0) ``` - Set up silent recording ``` kotlin mRecord.setMute(false) ``` - Double speed recording ``` kotlin /** * @param speed contains 0.25 0.5 1.0 2.0 4.0 times the speed */ mRecord.setSpeed(mSpeed) ``` ### Start recording - Start recording a video ``` kotlin /** * Start recording a video * @param path Recorded video save address * @param width The width of the recorded video. The SDK will do a 16-times integer operation. The width of the final output video may be inconsistent with the setting. * @param height The height of the recorded video. The SDK will do a 16-times integer operation. The width of the final output video may be inconsistent with the setting. * @param videoBitRate The bit rate of the video output. If it is set to 2000, it is 2M. The final output and the set may be different. * @param frameRate frame rate of video output * @param useHardWareEncode whether to use hard coding, if set to true, and hard coding is not supported, it will automatically switch to soft coding * @param audioSampleRate audio sample rate * @param audioChannel number of audio channels * @param audioBitRate audio bit rate * @param duration * @return Int ErrorCode.SUCCESS is success, others are failures * @throws InitRecorderFailException */ mRecord.startRecording("/sdcard/a.mp4", 720, 1280, 2000, // 2M bit rate 30, false, 44100, 1, // Mono 128, // 128K Rate Int.MAX_VALUE) ``` - End recording ``` kotlin mRecord.stopRecording() ``` ### Video editing #### Initialization - Create editor instance ``` kotlin mVideoEditor = TrinityCore.createEditor(this) ``` - Set preview screen ``` kotlin val surfaceView = findViewById(R.id.surface_view) mVideoEditor.setSurfaceView(surfaceView) ``` #### Import video - Add a snippet ``` kotlin val clip = MediaClip(file.absolutePath) mVideoEditor.insertClip(clip) ``` - Add fragments based on subscripts ``` kotlin val clip = MediaClip(file.absolutePath) mVideoEditor.insertClip(0, clip) ``` - Delete a clip ``` kotlin /** * Delete a segment in accordance with the subscript */ mVideoEditor.removeClip(index) ``` - Get the number of fragments ``` kotlin val count = mVideoEditor.getClipsCount() ``` - Get a clip based on the subscript ``` kotlin /** * If the fragment does not exist, returns a null */ val clip = mVideoEditor.getClip(index) ``` - Replace a snippet based on a subscript ``` kotlin mVideoEditor.replaceClip(index, clip) ``` - Get all clips ``` kotlin /** * Returns a collection of all clips */ val clips = mVideoEditor.getVideoClips() ``` - Total time to get all clips ``` kotlin val duration = mVideoEditor.getVideoDuration() ``` - Get the progress of the currently playing clip ``` kotlin val current = mVideoEditor.getCurrentPosition() ``` - Get start and end time of specified clip ``` kotlin val timeRange = mVideoEditor.getClipTimeRange(index) ``` - Find subscripts of clips based on time ``` kotlin val index = mVideoEditor.getClipIndex(time) ``` #### Background music - Add background music ``` kotlin /** * @param config background music json content * The specific json content is as follows: * { * "path": "/sdcard/trinity.mp3", * "startTime": 0, * "endTime": 2000 * } * json parameter explanation: * path: the local address of the music * startTime: the start time of this music * endTime: the end time of this music 2000 means this music only plays for 2 seconds */ val actionId = mVideoEditor.addMusic(config) ``` - Updated background music ``` kotlin /** * @param config background music json content * The specific json content is as follows: * { * "path": "/sdcard/trinity.mp3", * "startTime": 2000, * "endTime": 4000 *} * json parameter explanation: * path: the local address of the music * startTime: the start time of this music * endTime: the end time of this music 4000 means this music is played for 2 seconds from the start time to the end time */ val actionId = mVideoEditor.addMusic(config) ``` - Remove background music ``` kotlin /** * Remove background music * @param actionId must be the actionId returned when adding background music */ mVideoEditor.deleteMusic(actionId) ``` #### Add special effects - Add ordinary filters ``` kotlin /** * Add filters * For example: the absolute path of content.json is /sdcard/Android/com.trinity.sample/cache/filters/config.json * The path only needs /sdcard/Android/com.trinity.sample/cache/filters * If the current path does not contain config.json, the addition fails * The specific json content is as follows: * { * "type": 0, * "intensity": 1.0, * "lut": "lut_124 / lut_124.png" * } * * json parameter explanation: * type: reserved field, currently has no effect * intensity: filter transparency, no difference between 0.0 and camera acquisition * lut: the address of the filter color table, must be a local address, and it is a relative path * Path splicing will be performed inside sdk * @param configPath filter parent directory of config.json * @return returns the unique id of the current filter */ val actionId = mVideoEditor.addFilter(config) ``` - Update filters ``` kotlin /** * Update filters * @param configPath config.json path, currently addFilter description * @param startTime filter start time * @param endTime filter end time * @param actionId Which filter needs to be updated, must be the actionId returned by addFilter */ mVideoEditor.updateFilter(config, 0, 2000, actionId) ``` - Delete filter ``` kotlin /** * Delete filter * @param actionId Which filter needs to be deleted, it must be the actionId returned when addFilter */ mVideoEditor.deleteFilter (actionId) ``` - Add vibrato effect ``` kotlin /** * Add special effects * For example: the absolute path of content.json is /sdcard/Android/com.trinity.sample/cache/effects/config.json * The path only needs /sdcard/Android/com.trinity.sample/cache/effects * If the current path does not contain config.json, the addition fails * @param configPath filter parent directory of config.json * @return returns the unique id of the current effect */ val actionId = mVideoEditor.addAction(configPath) ``` - Updated vibrato effect ``` kotlin /** * Update specific effects * @param startTime The start time of the effect * @param endTime End time of the effect * @param actionId Which effect needs to be updated, must be the actionId returned by addAction */ mVideoEditor.updateAction(0, 2000, actionId) ``` - Remove vibrato effect ``` kotlin /** * Delete a special effect * @param actionId Which effect needs to be deleted, must be the actionId returned by addAction */ mVideoEditor.deleteAction(actionId) ``` #### Start preview -
