[Mlt-devel] Extracting the audio data

[bettinger c. <bc...@gm...>]

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
