NAME

fame_encode_slice - encode a single slice

CONTENTS

Synopsis
Description

SYNOPSIS


#include <fame.h> 

int fame_encode_slice(fame_context_t *context);

DESCRIPTION

fame_encode_slice() encodes a single slice (part of frame). Slices are processed from top to bottom of frame. The number of slices to process depends on the slices_per_frame parameter specified during fame_init

fame_start_frame should be called before coding the first slice and fame_end_frame should be called after coding the last slice.

context is the context handle previously returned by fame_open

RETURN VALUE

fame_encode_slice returns the number of bytes written to the bitstream buffer. If all slices have been coded, zero is returned.

EXAMPLE



    fame_start_frame(fc, &yuv, NULL);

while((length = fame_encode_slice(fc)) != 0)         write(output, buffer, length);

fame_end_frame(fc, NULL);

BUGS

MMX arithmetic performs bad at quality > 95%. Encoding of B frames is not yet supported.
