Detailed Description

Auxiliary method interface for custom video effects.

Method Documentation

- (int) allocateRGBATexture: (NvsSize) texSize

Users of custom video effects call this method to request a RGBA texture.

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

Parameters

texSize Applies for the size of the texture

Returns: Returns the texture ID of the application, and returns 0 to indicate that the application failed.

- (void) reclaimTexture: (int) texId

Users which using custom video special effects call this method to reclaim a previously applied texture.

Parameters

texId The texture ID to release

- (BOOL) uploadHostBufferToOpenGLTexture:	(NvsVideoFrameInfo *)	hostBuffer
textureId:	(int)	tId

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

Parameters

hostBuffer	Host buffer uploading
tId	The texture ID of uploading.
