  • How to save data of packet.data in ffmpeg using c language ?

    10 juin 2015, par patrick

    I’m try to build an app in c that extract audio from video and save it as audio file. I write the below code. I’m able to extract the audio but now the problem is how to save it. Thanks in advance.

    My code is :

    int main(int argc, char *argv[]) {
    
AVFormatContext *pFormatCtx = NULL;
    
int             i;
    
AVCodecContext  *pCodecCtx = NULL;
    
AVCodec         *pCodec = NULL;
    
AVFrame         *pFrame = NULL; 
    
AVPacket        packet;
    

    
AVDictionary    *optionsDict = NULL;
    

    
if(argc < 2) {
    
printf("Please provide a movie file\n");
    
return -1;
    
}
    
av_register_all();
    
if(avformat_open_input(&pFormatCtx, argv[1], NULL, NULL)!=0)
    
return -1; 
    

    
if(avformat_find_stream_info(pFormatCtx, NULL)<0)
    
return -1; 
    

    
av_dump_format(pFormatCtx, 0, argv[1], 0);
    

    
int audioStream=-1;
    
for(i=0; inb_streams; i++)
    
    if(pFormatCtx->streams[i]->codec->codec_type==AVMEDIA_TYPE_AUDIO) {
    
        audioStream=i;
    
        break;
    
    }
    
if(audioStream==-1)
    
return -1; 
    

    
pCodecCtx=pFormatCtx->streams[audioStream]->codec;
    

    
pCodec=avcodec_find_decoder(pCodecCtx->codec_id);
    
if(pCodec==NULL) {
    
    fprintf(stderr, "Unsupported codec!\n");
    
    return -1; // Codec not found
    
}
    

    
if(avcodec_open2(pCodecCtx, pCodec, &optionsDict)<0)
    
return -1; 
    

    
pFrame=avcodec_alloc_frame();
    
packet.data = NULL;
    
packet.size = 0;
    

    
while(av_read_frame(pFormatCtx, &packet)>=0) {
    
    int got_frame = 0;
    
    int ret = avcodec_decode_audio4(pCodecCtx, pFrame, &got_frame, &packet);
    
    if(got_frame && packet.stream_index==audioStream) {
    
        //save result but how???
    
    }
    
    av_free_packet(&packet);
    
}
    
av_free(pFrame);
    
avcodec_close(pCodecCtx);
    
avformat_close_input(&pFormatCtx);
    
return 0;
    
}
