Hi , i need to make a school project , a OGG Vorbis Player for Blackfin BF 537 !

 

I don't know very well DSP programing , but i know C++ !

 

So i have this Vorbis player( in attachments) but it plays just a portion of the file , it reads a number of bytes (NUM_BYTES_TO_DECODE) then it plays them , i need it to play all the file , i thought that i need two buffers , maybe the SDRam memory (bank_A and bank_B something like that ? ) , and a DMA transfer to transfer in one buffer while i am reading (playing) from the other one !

 

Can you help me with that ?

 

It is my ideea not so good ? Any suggestion for other implentation ?

 

If you want to test it with a file you need to encode it to 48 Khz with ogg drop (debug folder)!

 

 

 

 

 

Thanks very much , Mihai Georgescu !
