gst_vp9_bit_writer_frame_header 

GstVp9BitWriterResult
gst_vp9_bit_writer_frame_header (const GstVp9FrameHdr * frame_hdr,
                                 guint8 * data,
                                 guint * size)

Generating the according VP9 bit stream by providing the frame header.

Parameters:

frame_hdr –

the frame header of GstVp9FrameHdr to write

data –

the stream generated by the frame header

size –

the size in bytes of the input and output

Returns (GstVp9BitWriterResult) –

a GstVp9BitWriterResult

Since : 1.24

gst_vp9_bit_writer_superframe_info 

GstVp9BitWriterResult
gst_vp9_bit_writer_superframe_info (guint frame_num,
                                    const gint * frame_size,
                                    guint8 * data,
                                    guint * size)

Appending the super frame info at the end of this stream. Note: the input data should already contain all frames' data in the same order of frame_size.

Parameters:

frame_num –

the frame number to composite this super frame

frame_size –

the size of each frame

data –

the stream data of this super frame

size –

the size in bytes of the input and output

Returns (GstVp9BitWriterResult) –

a GstVp9BitWriterResult

Since : 1.24
