Function Documentation

const AVDVProfile* av_dv_codec_profile ( int  width,
int  height,
enum AVPixelFormat  pix_fmt 
)

Get a DV profile for the provided stream parameters.

const AVDVProfile* av_dv_codec_profile2 ( int  width,
int  height,
enum AVPixelFormat  pix_fmt,
AVRational  frame_rate 
)

Get a DV profile for the provided stream parameters. The frame rate is used as a best-effort parameter.

const AVDVProfile* av_dv_frame_profile ( const AVDVProfile sys,
const uint8_t *  frame,
unsigned  buf_size 
)

Get a DV profile for the provided compressed frame.

Parameters
systhe profile used for the previous frame, may be NULL
framethe compressed data buffer
buf_sizesize of the buffer in bytes
Returns
the DV profile for the supplied data or NULL on failure
