Vorbis - Oct 2005 - Heap Memory for Ogg Parser:

Hi,

What is the exact heap memory required for Ogg Parser
in floating as well as tremor vorbis decoder  ??
because both use different parsers?

If i neglect the CRC check i think only 2kB of heap is
sufficient for parsing, currently 8kB of buffer is
used in vorbis, excluding bodydata, which is 1024*16,
and lacing values of 1024 *4 etc ... Is this really
required?

Many thanks in advance..

-Ram

Until now, the largest ogg file I ever decoded was about 15 kb.  Now I am 
trying to decode files that are
approximated 2 to 3 times larger, and the program is crashing.  Could 
someone point out my problem?

 vorbis_info *vi = ov_info(&vf,-1);
 memset(&m_Format, 0, sizeof(m_Format));
 m_Format.cbSize          = 0;
 m_Format.nChannels       = vi->channels;
 m_Format.wBitsPerSample  = 16;
 m_Format.nSamplesPerSec  = vi->rate;
 m_Format.nAvgBytesPerSec = m_Format.nSamplesPerSec * m_Format.nChannels *
2;
 m_Format.nBlockAlign     = 2 * m_Format.nChannels;
 m_Format.wFormatTag      = 1;

 int eof = 0;
 int current_section;
 while(!eof)
 {
  long bytes_read = ov_read(&vf, m_lpData + dwBufferLength, 4096, 0, 2, 1, 
&current_section);
  if(bytes_read == 0)
   // EOF
   eof = 1;
  else
   dwBufferLength += bytes_read;
 }
