Reading Opus File, searching for Encoded-Audio Data

0

I want to get the Encoded Opus-Audio Data without performing the decoding process. I have written functions using the RFCs to read Ogg-pages and the Opus-header and Opus-Tags. I also could identify the next Ogg-page, but where does the Opus-data packet start, especially where is the Opus-TOC header? Does it start right after the OGG-Packet, is is part of the Ogg-Packet?

Thanks.

I found the solution, I had some error in calculating the length of the OggS-Page. Once I solved this, the Opus TOC-Header was the next byte within the stream.
