Detailed Description
Auxiliary method interface for custom video effects.
Method Documentation
◆ allocateRGBATexture:
| - (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.
◆ allocateRGBATexture:format:
| - (int) allocateRGBATexture: | (NvsSize) | texSize | |
| format: | (NvsGpuVideoFrameFormat) | fmt | |
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 fmt Applies for format of the texture
- Returns
- Returns the texture ID of the application, and returns 0 to indicate that the application failed.
◆ reclaimTexture:
| - (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
◆ uploadHostBufferToOpenGLTexture:gpuVideoFrame:
| - (BOOL) uploadHostBufferToOpenGLTexture: | (NvsVideoFrameInfoExt *) | hostBuffer | |
| gpuVideoFrame: | (struct NvsCustomVideoFxVideoFrame *) | tex | |
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.
◆ uploadHostBufferToOpenGLTexture:textureId:
| - (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.
