Chaining Example Code

- -

-The following is a run-through of the chaining example program supplied -with vorbisfile - chaining_example.c. -This program demonstrates how to work with a chained bitstream. - -

-First, relevant headers, including vorbis-specific "codec.h" and "vorbisfile.h" have to be included. - -

- - - - -
-

-#include "vorbis/codec.h"
-#include "vorbis/vorbisfile.h"
-#include "../lib/misc.h"
-
-
- -

Inside main(), we declare our primary OggVorbis_File structure. We also declare a other helpful variables to track our progress within the file. -

- - - - -
-

-int main(){
-  OggVorbis_File ov;
-  int i;
-
-
- -

This example takes its input on stdin which is in 'text' mode by default under Windows; this will corrupt the input data unless set to binary mode. This applies only to Windows. -

- - - - -
-

-#ifdef _WIN32 /* We need to set stdin to binary mode under Windows */
-  _setmode( _fileno( stdin ), _O_BINARY );
-#endif
-
-
- -

We call ov_open_callbacks() to -initialize the OggVorbis_File -structure. ov_open_callbacks() -also checks to ensure that we're reading Vorbis format and not -something else. The OV_CALLBACKS_NOCLOSE callbacks instruct -libvorbisfile not to close stdin later during cleanup.

- -

- - - - -
-

-  if(ov_open_callbacks(stdin,&ov,NULL,-1,OV_CALLBACKS_NOCLOSE)<0){
-    printf("Could not open input as an OggVorbis file.\n\n");
-    exit(1);
-  }
-
-
-
- -

-First we check to make sure the stream is seekable using ov_seekable. - -

Then we're going to find the number of logical bitstreams in the physical bitstream using ov_streams. - -

We use ov_time_total to determine the total length of the physical bitstream. We specify that we want the entire bitstream by using the argument -1. - -

- - - - -
-

-  if(ov_seekable(&ov)){
-    printf("Input bitstream contained %ld logical bitstream section(s).\n",
-	   ov_streams(&ov));
-    printf("Total bitstream playing time: %ld seconds\n\n",
-	   (long)ov_time_total(&ov,-1));
-
-  }else{
-    printf("Standard input was not seekable.\n"
-	   "First logical bitstream information:\n\n");
-  }
-  
-
-
- -

Now we're going to iterate through each logical bitstream and print information about that bitstream. - -

We use ov_info to pull out the vorbis_info struct for each logical bitstream. This struct contains bitstream-specific info. - -

ov_serialnumber retrieves the unique serial number for the logical bistream. ov_raw_total gives the total compressed bytes for the logical bitstream, and ov_time_total gives the total time in the logical bitstream. - -

- - - - -
-

-  for(i=0;i<ov_streams(&ov);i++){
-    vorbis_info *vi=ov_info(&ov,i);
-    printf("\tlogical bitstream section %d information:\n",i+1);
-    printf("\t\t%ldHz %d channels bitrate %ldkbps serial number=%ld\n",
-	   vi->rate,vi->channels,ov_bitrate(&ov,i)/1000,
-	   ov_serialnumber(&ov,i));
-    printf("\t\tcompressed length: %ld bytes ",(long)(ov_raw_total(&ov,i)));
-    printf(" play time: %lds\n",(long)ov_time_total(&ov,i));
-  } 
-
-
-

-When we're done with the entire physical bitstream, we need to call ov_clear() to release the bitstream. - -

- - - - -
-

-  ov_clear(&ov);
-  return 0;
