Unexpected opus_encode results when doubelling frame size
Hello!
I have been using
int iByteSizeEncoded = opus_encode(m_enc,
m_ShortRawInput,960,m_EncodedBytes, 4000);
iByteSizeEncoded was 120 as expected.
Now when I double the frame size...
int iByteSizeEncoded = opus_encode(m_enc,
m_ShortRawInput,960*2,m_EncodedBytes, 4000);
... iByteSizeEncoded is not 240 as expected, but 239.
This seems...

Encoder off by one
...m_RawBytes, sizeof(short),
(5760/sizeof(short)), fin);
for(int i=0;i<iShortsRead;i++)
{
opus_int32 s;
s=m_RawBytes[2*i+1]<<8|m_RawBytes[2*i];
s=((s&0xFFFF)^0x8000)-0x8000;
m_ShortsInput[i]=s;
}
int iByteSizeEncoded = opus_encode(m_enc, m_ShortsInput,
(5760/sizeof(short)), m_EncodedBytes, (960*6));

If you encode with
int iByteSizeEncoded = opus_encode(m_enc, m_ShortsInput,
(1920/sizeof(short)), m_EncodedBytes, (960*6));
... the byte size is 120.
I thought that an odd value like 359 has to be a fault on my side.
I thought it would be a multiple of something.
So 359 is really correct???
Thank you for clearing this up.

OPUS implementation with FPGA
Hi,
We would like to use the OPUS codec @ 16 kHz sampling rate and max 32 kbps.
What about implementing an OPUS coder and decoder in an FPGA? Has this been done? Would either coder or decoder more suitable for FPGA implementation?
Best regards
Fredrik Bonde
