opusenc: Unsupported FLAC input file #66

Closed andreipoe closed 2 years ago

andreipoe commented 2 years ago

opusenc fails on some input FLAC files with a generic error:

$ opusenc --bitrate 160 1.{flac,opus}
Error: unsupported input file: 1.flac

$ file 1.flac
1.flac: Audio file with ID3 version 2.4.0, contains:FLAC audio bitstream data, 24 bit, stereo, 96 kHz, 28360569 samples

These FLAC files play without issue and are verified ok by flac -t.

$ opusenc --version
opusenc opus-tools 0.2 (using libopus 1.3.1)

Thanks for your work on this @mark4o. I've tried a fresh build from the latest source code with the same files and I'm still seeing the same error. I suspect it might be related to the 24 bit/96 kHz quality; I've never encountered the issue with 16-bit files.
