Foobar2000 and lossywav with wavpack

Cheers

I think I am able to reproduce your problem, but I'm very confused. I had to go back to WavPack version 4.75 before this worked correctly, which is almost 5 years old. I find it weird that nobody else has seen this, but there it is.

I'm attaching a copy of that version of the wavpack executable for you to try because that version is so old I don't have it up anymore, although I would understand if didn't feel comfortable using it. I would like to know if this fixes your issue.

I would also like to figure out what's going on, but unfortunately I can't easily see the output of the wavpack executable when it fails, so I don't know what it's complaining about, and when I use it stand-alone with the cmd.exe and lossyWAV, everything works fine. The most significant change from 4.75.2 to 4.80.0 was the inclusion of full Unicode support, which involves changes to the main shell interface, so it's probably related to that. I'll continue investigating.

To the wider HA community, does anyone know anything about this? Is anyone using foobar2000+lossyWAV in this way with a newer version of WavPack?

Okay, I sort of figured it out. It had to do with the format of the command-line and my use of CommandLineToArgvW() to handle Unicode command lines (which has "a special interpretation of backslash characters when they are followed by a quotation mark character"). I don't really understand everything, but I fixed the string and it works with old and new versions of WavPack:

Code: [Select]
/d /c c:\"program files (x86)"\foobar2000\lossywav - --quality standard --silent --stdout|"c:\program files (x86)\foobar2000\wavpack" -hm --blocksize=512 --merge-blocks -i - %d

The only difference is the placement of the two quotation marks in the name for the WavPack executable. The quotation marks in the lossywav filename have to stay where they are.

Hope this is actually the problem you were having...  :)

Great, your new command line works perfectly.
Thanks a lot!
