Member Function Documentation

allocateRGBATexture()

int com.meicam.sdk.NvsCustomVideoFx.RenderHelper.allocateRGBATexture	(	int	texWidth,
		int	texHeight
	)

Users of custom video effects call this method to apply for an RGBA texture.

Note: The texture requested by this method must be recycled by calling reclaimTexture, otherwise there will be a memory leak!

Parameters

texWidth	The width of the requested texture.
texHeight	The height of the requested texture.

Returns

Returns the texture ID of the application, and returning 0 indicates that the request fails.

reclaimTexture()

void com.meicam.sdk.NvsCustomVideoFx.RenderHelper.reclaimTexture

(

int

texId

)

Users of custom video effects call this method to reclaim a previously allocated texture.

Parameters

texId

the texture ID to release.

uploadHostBufferToOpenGLTexture()

boolean com.meicam.sdk.NvsCustomVideoFx.RenderHelper.uploadHostBufferToOpenGLTexture	(	ByteBuffer	buffer,
		NvsVideoFrameInfo	bufferInfo,
		int	texId
	)

Users which using custom video effects call this method to upload a Host buffer to the OpenGL texture.

Parameters

hostBuffer	Host buffer uploading
texId	The texture ID of uploading.
