Detailed Description

Encoder output packet.

This structure contains the different kinds of output data the encoder may produce while compressing a frame.

Member Data Documentation

buf

void* vpx_codec_cx_pkt::buf

compressed data buffer

[1/2]

union { ... } vpx_codec_cx_pkt::data

packet data

[2/2]

union { ... } vpx_codec_cx_pkt::data

packet data

duration

unsigned long vpx_codec_cx_pkt::duration

duration to show frame (in timebase units)

firstpass_mb_stats

vpx_fixed_buf_t vpx_codec_cx_pkt::firstpass_mb_stats

first pass mb packet

flags

vpx_codec_frame_flags_t vpx_codec_cx_pkt::flags

flags for this frame

[1/2]

struct { ... } vpx_codec_cx_pkt::frame

data for compressed frame packet

[2/2]

struct { ... } vpx_codec_cx_pkt::frame

data for compressed frame packet

height

unsigned int vpx_codec_cx_pkt::height[VPX_SS_MAX_LAYERS]

frame height

kind

enum vpx_codec_cx_pkt_kind vpx_codec_cx_pkt::kind

packet variant

layer_psnr

struct vpx_psnr_pkt vpx_codec_cx_pkt::layer_psnr[VPX_SS_MAX_LAYERS]

layer_sizes

size_t vpx_codec_cx_pkt::layer_sizes[VPX_SS_MAX_LAYERS]

pad

char vpx_codec_cx_pkt::pad[128 - sizeof(enum vpx_codec_cx_pkt_kind)]

fixed sz

partition_id

int vpx_codec_cx_pkt::partition_id

the partition id defines the decoding order of the partitions.

Only applicable when "output partition" mode is enabled. First partition has id 0.

psnr [1/3]

double vpx_codec_cx_pkt::psnr[4]

PSNR, total/y/u/v.

[2/3]

struct { ... } ::vpx_psnr_pkt vpx_codec_cx_pkt::psnr

data for PSNR packet

[3/3]

struct { ... } ::vpx_psnr_pkt vpx_codec_cx_pkt::psnr

data for PSNR packet

pts

vpx_codec_pts_t vpx_codec_cx_pkt::pts

time stamp to show frame (in timebase units)

raw

vpx_fixed_buf_t vpx_codec_cx_pkt::raw

data for arbitrary packets

samples

unsigned int vpx_codec_cx_pkt::samples[4]

Number of samples, total/y/u/v.

spatial_layer_encoded

uint8_t vpx_codec_cx_pkt::spatial_layer_encoded[VPX_SS_MAX_LAYERS]

Flag to indicate if spatial layer frame in this packet is encoded or dropped.

VP8 will always be set to 1.

sse

uint64_t vpx_codec_cx_pkt::sse[4]

sum squared error, total/y/u/v

sz

size_t vpx_codec_cx_pkt::sz

length of compressed data

twopass_stats

vpx_fixed_buf_t vpx_codec_cx_pkt::twopass_stats

data for two-pass packet

width

unsigned int vpx_codec_cx_pkt::width[VPX_SS_MAX_LAYERS]

Width and height of frames in this packet.

VP8 will only use the first one. frame width
