Opusenc fails to encode very short flac files

[MarcroSoft]

Hi,
I'm not sure if it's related to opus or flac, but when I try to encode a short flac file with opusenc it says:
ERROR: Could not open FLAC stream.
Error: unsupported input file: synth1.flac
I did the following, you will need sox for this but any file will do:
sox -n synth1.flac synth 1
opusenc synth1.flac synth1.opus
Which does not work, 1 second file.
And this:
sox -n synth5.flac synth 5
opusenc synth5.flac synth5.opus
Works, 5 seconds file.
Any ideas? And sorry if it's in the wrong place, I'm not an expert in this.
Thanks,
Marc

Hi,
I just tried it with opus-tools from homebrew on mac, and there it works.
The one that fails is both the one from rarewares and my own built from media autobuild suite for windows.
So maybe it's a windows thing?
Anyway I hope someone can take a look on it.

FLAC support in opus-tools is optional. Probably one binary was compiled with FLAC support and other wasn't.

Hi,
No, as I say, longer files works fine, it's only short files that crash.

I've made some progress.
It seams to work when compiling opus-tools 0.2 with dynamic libflac-8.dll, haven't tried static yet, but not from git.
I think this should be opened in opus-tools, so I'm closing it. Sorry for disturbing you.
