Detailed Description

Streaming context.

The streaming context class(NvsStreamingContext) can be refered to as the entry point of the whole SDK framework. In the process of development, NvsStreamingContext provides the static sharedInstance interface, which is the only instance to create streaming context. Through this instantce object, we can turn on the recording device to record videos, adding effects to capture videos, set various parameters for recording, which include autofocus, automatic exposure adjustment, swtiching on/off of the light supplement and so on. Meanwhile, this instance can also create timelines, connecting timelines to real-time preview windows to view the recorded videos in real-time. When the whole video has been produced completely, please destroy the instances of streaming context. When recording with special effects or adding resources packages (recording effects package, scene resources package and so on), one has to first install the package and obtain packageID after installation. For built-in special effects, one only needs to obtain the name of the effect in order to use them.
In the SDK, users need to adopt the full pathway when importing resources or authorizations.

Warning: For NvsStreamingContext class, all public APIs must be used in the UI thread except getAVFileInfo(), detectVideoFileKeyframeInterval(),createVideoFrameRetriever(), which can be used across threads.

◆ checkDontSetCameraParamOnRecordingWithSystemRecorder()

boolean com.meicam.sdk.NvsStreamingContext.checkDontSetCameraParamOnRecordingWithSystemRecorder ( )

inline

Checks if the camera's parameters cannot be set when recording with system recorder.

For certain Android mobile phones, when recording with system built-in recorders, if one set cameras' parameters (for instance the exposure compensation or autofocus), the recorded video will have problems or the recording cannot be stopped. To avoid this kind of problems, the Meishe SDK keeps a blacklist of unwantted Android phones. If a phone is in the blacklist, any setting of the parameters while recording will be ignored. This method is used to check if current phone used is in the blacklist. If yes, the user may have to make certain adjustment to the recording interface, say disabling the exposure compensation button. Note: if the user does not use the system built-in recorder when recording, then the blacklist will not work.

◆ startCapturePreview()

boolean com.meicam.sdk.NvsStreamingContext.startCapturePreview	(	int	captureDeviceIndex,
		int	videoResGrade,
		int	flags,
		NvsRational	aspectRatio
	)

inline

Starts the capture preview.

Parameters

captureDeviceIndex	Index of the capture device
videoResGrade	Grade for video capture resolution. Please refer to Grade for video capture resolution. The video resolution grade means the shorter edge's resolution value when capturing video (could be the height or the width). According to the aspectRatio (if null then system's capturing device will determine aspect ratio), another edge's resolution value will be calculated (could be the height or the width). Four grades include LOW, MEDIUM, HIGH and SUPER_HIGH, of which correspond to 360p, 480p, 720p and 1080p. Android SDK's front-faced and back-faced cameras should be of the same resolution grade. There are two ways to record, recording with special effects and without. When recording with special effects (not using the system's built-in recorder), the SDK will evaluate user's phone's processing ability. If the phone is capable of process the recorded video, then the video will be recorded in resolution grade as set. If not, the SDK will lower the resolution grade to a level that the user's phone are capable of. For example: when using certain model of phone and setting to SUPER_HIGH grade, of which the phone are not capable of supporting, the SDK will lower the grade to HIGH or MEDIUM, thus resulting the grade recorded is not same as the grade user sets. Likewise, if recording without special effects (using the system's built-in camera), then the resolution grade will be determined according to camera's capability. If the camera cannot satisfy the grade setted, the SDK would lower the resolution grade when recording. If the user wants to customize the recording resolution, say 540960 pixels, then the user will need to record a video with identical aspect ratio, create a timeline with aspect ratio of 540960 and compile it to file. When compiling, there is no grade corresponding to a height of 960p, thus the user needs to call setCustomCompileVideoHeight() to customize the height before compilation. Then the user needs to call compileTimeline(), with the height grade set to COMPILE_VIDEO_RESOLUTION_GRADE_CUSTOM. The code may be used as follows: NvsVideoResolution videoEditRes = new NvsVideoResolution(); videoEditRes.imageWidth = 540; videoEditRes.imageHeight = 960; videoEditRes.imagePAR = new NvsRational(1, 1); NvsRational videoFps = new NvsRational(25, 1); NvsAudioResolution audioEditRes = new NvsAudioResolution(); audioEditRes.sampleRate = 44100; audioEditRes.channelCount = 2; mTimeline = mStreamingContext.createTimeline(videoEditRes, videoFps, audioEditRes); mStreamingContext.setCustomCompileVideoHeight(960); mStreamingContext.compileTimeline(mTimeline, 0, mTimeline.getDuration(), m_compilePath, NvsStreamingContext.COMPILE_VIDEO_RESOLUTION_GRADE_CUSTOM, NvsStreamingContext.COMPILE_BITRATE_GRADE_HIGH, 0);
flags	Flag field, if there is no special requirement, please fill in 0. Please refer to Flag of capturing.
