The basic format is shared with Vorbis, but the 'magic signature' is different ('OpusTags' instead of '0x05vorbis') and vorbis puts a 0x01 value in an extra byte after the last tag. The OpusTag packet layout is de...

Would it be possible to include a re-export of the malloc, calloc, realloc, and free being used by opus file's implementation of OpusTags handling? This might seem redundant or ridiculous but I'm having difficulty getting the right versions that my compiler allows that's compatible with libopusfile. In the debugger I can see that the memory location that my malloc is returning is different from what libopusfile is returning...

Hello Ralph I ran the opusenc.exe on a wave file and checked the OpusTag section. My concern is on Total Segment Size being >> than the actual data being put. Is this just an example of implementation or does a size of 764 BYTES kept as a place holder for putting more data? 4f 67 67 53 = Oggs 00 = Version 00 = Header 00 00 00 00 00 00 00 00 = Granule Position a5...

Hi all! Using the code in opus_demo.c I write a c program for encode and decode the audio from one microphone, I can encode and decode raw audio into .opus file, but really is not an opus file because i need to add the "OpusHead" and the "OpusTags". In order that any opus player can play that file. So I only need in my c program how to add this streams to my file an how to create the complete opus file I do not find any information about creating the header and how to store the opus packets that i encode and decode Grettings Toni -...

Hello Tim Is there a format document on the OpusTag structure? Search always shows up Vorbis but not Opus. Regards Amit On Mon, May 9, 2016 at 4:01 PM, Timothy B.

I would like to be able to add/modify tags (like artist, album, title) to opus files. The opusenc utility does a fine job of creating tags when creating opus files, but I would like to be able to modify existing opus files from the command line. vorbiscomment can add tags to existing ogg files, but it doesn't work with opus files. Does anyone have a solution for this? Thanks, Chris
