Conversion to WavPack

Post by MI3Guy » Mon Apr 02, 2012 7:54 pm

Is there any chance that an option could be added to convert audio to WavPack? While there might be some problems with larger streams (possibly 5.1 and up) due to the artificial maximum file size, it would be very helpful with some more obscure audio configurations such as 4.0 audio. FLAC interprets all 4.0 audio as 2F2R, but often it is actually 3F1R and WavPack supports this channel mapping.

You think too badly about MakeMKV. When converting to FLAC, MakeMKV inserts original channel layout mask into FLAC metadata and any software that checks for it ( madflac is the one ) should apply correct channel assignment.

Really? I wasn't even aware that could be done with flac? Is that the only program that supports it? I mostly use XBMC.

Hey, is this confirmed? And any player should recognize it? No madflac here, all my systems run Linux, VLC, GStreamer, XBMC.

It doesn't work for me in LAV Audio decoder.

What I did instead is importing the FLAC using Audacity, then export it as FLAC 6.1 audio. It'll ask you how you want to map them, and any unmapped channel will be silent. So it is 4.0 wrapped in 6.1 audio.

The next libavformat version should support the FLAC channel layout medatata, when present in raw FLAC streams or in Matroska CodecPrivate data.
