Function Documentation

void ff_audio_convert_set_func ( AudioConvert ac,
enum AVSampleFormat  out_fmt,
enum AVSampleFormat  in_fmt,
int  channels,
int  ptr_align,
int  samples_align,
const char *  descr,
void conv 
)

Set conversion function if the parameters match.

This compares the parameters of the conversion function to the parameters in the AudioConvert context. If the parameters do not match, no changes are made to the active functions. If the parameters do match and the alignment is not constrained, the function is set as the generic conversion function. If the parameters match and the alignment is constrained, the function is set as the optimized conversion function.

Parameters
acAudioConvert context
out_fmtoutput sample format
in_fmtinput sample format
channelsnumber of channels, or 0 for any number of channels
ptr_alignbuffer pointer alignment, in bytes
samples_alignbuffer size alignment, in samples
descrfunction type description (e.g. "C" or "SSE")
convconversion function pointer
