I want to create simple pcm to mp3 C++ project. I want it to use LAME. I love LAME but it's really big. so I need some kind of OpenSource working from pure code with pure lame code workflow simplifier. So to say I give it File with PCM and DEST file. Call something like:
LameSimple.ToMP3(file with PCM, File with MP3 , 44100, 16, MP3, VBR);
ore such thing in 4 - 5 lines (examples of course should exist) and I have vhat I needed It should be light, simple, powerfool, opensource, crossplatform.
Is there any thing like this?
Lame really isn't difficult to use, although there are a lot of optional configuration functions if you need them. It takes slightly more than 4-5 lines to encode a file, but not much more. Here is a working example I knocked together (just the basic functionality, no error checking):
#include <stdio.h>
#include <lame/lame.h>
int main(void)
{
int read, write;
FILE *pcm = fopen("file.pcm", "rb");
FILE *mp3 = fopen("file.mp3", "wb");
const int PCM_SIZE = 8192;
const int MP3_SIZE = 8192;
short int pcm_buffer[PCM_SIZE*2];
unsigned char mp3_buffer[MP3_SIZE];
lame_t lame = lame_init();
lame_set_in_samplerate(lame, 44100);
lame_set_VBR(lame, vbr_default);
lame_init_params(lame);
do {
read = fread(pcm_buffer, 2*sizeof(short int), PCM_SIZE, pcm);
if (read == 0)
write = lame_encode_flush(lame, mp3_buffer, MP3_SIZE);
else
write = lame_encode_buffer_interleaved(lame, pcm_buffer, read, mp3_buffer, MP3_SIZE);
fwrite(mp3_buffer, write, 1, mp3);
} while (read != 0);
lame_close(lame);
fclose(mp3);
fclose(pcm);
return 0;
}
