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

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. |
