I dropped a debug build of the plugin in Winamp and checked it out. The libopus libraries themselves are reporting that the files have malformed headers (Error code -133 in the header definition.) It doesn't indicate why or how, just the error code. I opened the files in my hex editor and saw that the OggS pages seemed to be formatted correctly so it must be in the file container payload somewhere. I haven't looked yet in the payload but maybe sometime during the weekend.

Most of them work great thanks. Though I've hit a couple where I can't get the tags to load into Winamp. They've been tagged in the same way as the other files which work (using AudioShell), and I can see the tags are present in the same way as with the other files if I open them with a text editor.

Here are the files in question if you're interested to have a look sometime:

Thanks,

After further investigation of the files in a modified debug build of the plugin I discovered that my initial assessment of the integrity of the files' structure was wrong, very wrong. I found that further down in the files there were severe errors in the OggS page layout, namely, it looks as though either multiple sections of the files are missing OR the original encoder (lavf) overwrote key OggS page headers by mistake. These errors run the entire length of the files intermittently and are not recoverable.

If you obtained these files from online, try re-downloading them. If you converted them yourself, please please please please please use a different converter.

The opusfile library provides seeking, decode, and playback of Opus
streams in the Ogg container (.opus files) including over http(s) on
posix and windows systems.

opusfile depends on libopus and libogg. The included opusurl library
for http(s) access depends on opusfile and openssl.

Changes since the v0.11 release:

- Fix stack overflow buffering out-of-sequence streams.
- Fix possible divide-by-zero.
- Fix issues with seeking in the win32 backend.
- Fix an issue where the seek algorithm could be confused
by stream data changing between reads.
- Clean up compiler and scan-build warnings.
- Avoid use of the deprecated ftime() function
which has Y2038 problems.
- Remove undefined behaviour memcpy(NULL) in op_read_native().
- Visual Studio project files updated for libogg 1.3.4 library name
change.
- Various build systems updates.
- Various integration and testing environment improvements.

This release is backward-compatible with the previous release. We
recommend all users upgrade.

Note that because of the removal of certificate store hooks in openssl
1.1.1 and later, there are unfortunately no supported versions of that
library which can be used with the code in opusurl to validate https
responses against the system certificate store on Windows. Using the
system default access to the certificate store on other platforms works
fine.

ile-0.12.zip

No Windows build is available for this release. Developers should
integrate the source code directly into their applications.

Programming documentation is available in tree and online at
https://opus-codec.org/docs/.

The library is functional, but there are likely issues we didn't find
in our own testing. Please give feedback on this mailing list, in #opus
on irc.freenode.net, or at https://gitlab.xiph.org/xiph/opusfile.

Thanks to everyone who contributed!

Because of the requirements for Windows on this release it looks like I'll have to do a major rewrite of the opus handling functions to integrate these changes. It might take a while since my job usually leaves me exhausted by the end of the day.
