The uncompressed file is ~12.9 GB and the "wavpack -f" file is ~6.8 GB

file name: fellowship.wv
file size: 2960974266 bytes
source: 24-bit ints at 48000 Hz
channels: 7 (FL,FR,FC,LFE,BC,SL,SR)
duration: 3:48:18.77
modalities: lossless, fast
compression: 78.56%
ave bitrate: 1729 kbps
encoder version: 4
file wrapper: 68 byte RIFF header

I can play the file in DeadBeef (it uses libwavpack instead of ffwavpack), but can't seek past ~92 minutes. DeadBeef will play everything beyond ~92 minutes as long as I start playing the file before ~92 minutes.

I've compressed similarly large 24-bit but 6-channel files before, and this didn't happen.

The source file is the lossless audio from the "Lord of the Rings: The Fellowship of the Ring: Special Extended Edition" blu-ray

I tried hybrid lossless compression at ~1792 kb/s.

I could play and seek throughout the whole file, but there was much digital "stuttering" throughout the file when being played.
