"Failed to analyze files" for opus format in 0.8.0+ #9

Closed alexmbird closed 5 years ago

alexmbird commented 5 years ago

It appears something in r128gain's opus handling has broken between release 0.7.1 and the latest. For example the command r128gain -r -a -o . previously ran without error on a directory of .opus files (freshly written by ffmpeg+libopus) in 0.7.1, but on a fresh install I see the following:

$ ~/.local/bin/r128gain -r -a -o .

Pinning my local install to r128gain==0.7.1 is a workaround.

In generating the latter I've noticed another problem: despite the failure r128gain is producing an exit code of 0. I'd expect it to be something else so the failure can be detected from a calling script.

desbma commented 5 years ago

OK I have reproduced this, really stupid bug, I will provide a fix soon.

The return code of 0 is because only the album gain scan fails, the file are properly scanned and tagged with track gain.

alexmbird commented 5 years ago

Awesome, much appreciated.

WRT the return code - I get that the operation is partially successful, but after a user has explicitly specified --album-gain on the command line I'd say its absence counts as failure.

desbma commented 5 years ago

For the return code, you have to consider that in recursive mode, user might scan hundreds of albums, with sometimes corrupt files (that was the case for a previous issue).

But I actually agree with you, I think the return code should be non zero in that case (I have created #10 to remind me to fix this).

alexmbird commented 5 years ago

Good point. Maybe a --strict mode is the best way to go - it'll satisfy tagging absolutists like me without breaking the recursive behaviour for everyone else.

Anyhow thanks for the fix and thanks for r128gain itself - it's a great tool.
