Summary of the bug:
How to reproduce:
{{{
% ffmpeg -i audio.mp4 audio.opus
opusinfo audio.opus
}}}
The generated `audio.opus` cannot be decoded with `opusdec` provided by
`opus-tools`(version: 0.2)
{{{
% opusdec audio.opus
Failed to open 'audio.opus'.
}}}
Debugging with `opusfile`(underlying `opusdec`), the error is
`OP_EBADTIMESTAMP`(The first or last granule position of a link failed
basic validity checks.)
And with `opusinfo` provided by `opus-tools`, there are many warnings:
