Hello,
I am using Mlt++ and I need to get the audio data of a media content. I
tried that :
#include <iostream>
#include <mlt++/Mlt.h>
int main*(*int argc*,* char**** argv*){*
Mlt*::*Factory*::*init*(**NULL**);*
Mlt*::*Profile ***m_profile *=* *new* Mlt*::*Profile *(*"square_ntsc_wide"*
);*
Mlt*::*Producer ***producer *=* *new* Mlt*::*Producer *(**m_profile*,*
"vamp.mp4"*);*
double fps *=* producer*->*get_fps*();*
//Mlt::Consumer *m_consumer = new Mlt::Consumer (*m_profile, "avformat",
"test.dvd");
//m_consumer->connect(*producer);
Mlt*::*Frame ***frame *=* producer*->*get_frame*(*0*);*
mlt_audio_format audioFormat*;*
int ***audio_data*;*
int frequency*,* channels*,* samples*;*
std*::*cout *<<* "ok1" *<<* std*::*endl*;*
audio_data *=* *(*int**)*frame*->*get_audio*(*audioFormat*,*
frequency*,*channels
*,* samples*);*
std*::*cout *<<* "ok2" *<<* std*::*endl*;*
//m_consumer->run();
std*::*cout *<<* "Finished" *<<* std*::*endl*;*
*return* 0*;*
*}*
I have no idea how get_audio works. Anyone could help me ?
Thanks in advance,
Cédric
