Converting 32 bit MLP to 32 bit FLAC?

I have some .MLP files which I'd like to convert to .FLAC for easier playback.

Examining the file with ffmpeg version 0.8.13-4:0.8.13-0ubuntu0.12.04.1 I get

Stream #0.0: Audio: mlp, 96000 Hz, 5.1, s32

If I try to convert it with ffmpeg, I get this notification

Incompatible sample format 's32' for codec 'flac', auto-selecting format 's16'
Output #0, flac, to 'test1.flac':
  Metadata:
    encoder         : Lavf53.21.1
    Stream #0.0: Audio: flac, 96000 Hz, 5.1, s16, 200 kb/s

If I use a libflac encoder

$ flac test.mlp --endian=big --channels=6 --sample-rate=96000 --sign=signed --bps=32
ERROR: invalid bits per sample '32' (must be 8/16/24)

So there I'm limited to 24 bits. Is there any way to get 32bit files from ffmpeg?

Try a libflac encoder. You can always store the uncompressed file somewhere, surely it’s not multiple terabytes, is it? – Daniel B – 2014-07-30T18:47:25.147

I get ERROR: invalid bits per sample '32' (must be 8/16/24) will add it to the question. – Terence Eden – 2014-07-30T19:57:53.307

Haha, oh well. Next time, I’ll read the fine print first: “Currently the reference encoder and decoders only support up to 24 bits per sample.”. Guess you’re out of luck, then.
