Member Function Documentation

◆ release()

virtual void agora::media::IVideoFrame::release ( )
pure virtual

◆ buffer()

virtual const unsigned char* agora::media::IVideoFrame::buffer ( PLANE_TYPE  type) const
pure virtual

◆ copyFrame()

virtual int agora::media::IVideoFrame::copyFrame ( IVideoFrame **  dest_frame) const
pure virtual

Copies the frame.

If the required size is larger than the allocated size, new buffers of the adequate size will be allocated.

Parameters
dest_frameAddress of the returned destination frame. See IVideoFrame.
Returns
  • 0: Success.
  • -1: Failure.

◆ convertFrame()

virtual int agora::media::IVideoFrame::convertFrame ( VIDEO_TYPE  dst_video_type,
int  dst_sample_size,
unsigned char *  dst_frame 
) const
pure virtual

Converts the frame.

Note
The source and destination frames have equal heights.
Parameters
dst_video_typeType of the output video.
dst_sample_sizeRequired only for the parsing of M-JPEG.
dst_framePointer to a destination frame. See IVideoFrame.
Returns
  • 0: Success.
  • < 0: Failure.

◆ allocated_size()

virtual int agora::media::IVideoFrame::allocated_size ( PLANE_TYPE  type) const
pure virtual

Retrieves the specified component in the YUV space.

Parameters
typeComponent type: PLANE_TYPE

◆ stride()

virtual int agora::media::IVideoFrame::stride ( PLANE_TYPE  type) const
pure virtual

Retrieves the stride of the specified component in the YUV space.

Parameters
typeComponent type: PLANE_TYPE

◆ width()

virtual int agora::media::IVideoFrame::width ( ) const
pure virtual

Retrieves the width of the frame.

◆ height()

virtual int agora::media::IVideoFrame::height ( ) const
pure virtual

Retrieves the height of the frame.

◆ timestamp()

virtual unsigned int agora::media::IVideoFrame::timestamp ( ) const
pure virtual

Retrieves the timestamp (90 ms) of the frame.

◆ render_time_ms()

virtual int64_t agora::media::IVideoFrame::render_time_ms ( ) const
pure virtual

Retrieves the render time (ms).

◆ IsZeroSize()

virtual bool agora::media::IVideoFrame::IsZeroSize ( ) const
pure virtual

Checks if a plane is of zero size.

Returns
  • true: The plane is of zero size.
  • false: The plane is not of zero size.

◆ GetVideoType()

virtual VIDEO_TYPE agora::media::IVideoFrame::GetVideoType ( ) const
pure virtual
