Hello!
Is there any way to get the bits per sample (BPS) from the MusePack file? Regards, Sebastian Andersson -------------------- "I have not failed. I've just found 10,000 ways that won't work." -Thomas Edison

Why would you want to know the BPS of the source file?

Regards, Sebastian Andersson  In this case, I need it for a function used by a BASS add-on (www.un4seen.com). But other reasons could be, to fill up the WAVEFORMAT structure with the proper information or whatever.

QUOTE (Garf) Why would the decoder care at all what the input resolution is, it doesn't matter at all for it? It can choose freely whatever resolution or format it wants to decode to, there is no relation needed to whatever the input was. This quote was related to AAC decoding but the same is true for MPC. -------------------- "To understand me, you'll have to swallow a world." Or maybe your words.

Great news, thanks Mr Peter!
I wonder there is no matter if I send a link to this thread to Rockbox team? Cause it could interest their iriverport project... Best regards, Tang PS: thanks also for foobar, even if it's a little off topic: i like your player |

EDIT: i've just understood how the Rockbox WiKi was working... So i added directly the useful links/info in the Wiki: http://www.rockbox.org/twiki/bin/view/Main...Writing_CODEC_s
feel free to correct if there is something wrong (will need registering thought) Pre edited post: QUOTE Just to say i've submited a link to this thread and the library itself on the rockbox board (for iriverport)...
here is the link: http://forums.rockbox.org/index.php?topic=103.0 Let's see if the Rockbox team will consider this... Best regards This post has been edited by Tang: Nov 3 2004, 03:00 |

I've just finished a first rough port of this library to pure C, instead of C++, since a lot of people refuse to include C++ code in their apps.
It's currently available in a darcs repository at http://www.caddr.com/code/libmusepack/ I've started adding some documentation too, which can be found here: http://www.caddr.com/code/libmusepack/docs/html/ I'd welcome any comments or suggestions. If you know of any project devs that would be interested in supporting musepack but have held off because of the C++ issue please let me know. Thanks for the original work of putting this library together. |

I updated the old library in BetaPlayer's MPC plugin to libmusepack 1.03. But I had to put back SeekTable[] for faster seeking. Was there a reason why this was removed from libmusepack?

Yes, I'am using the C++ version and the SeekTable was in the old version (before it was renamed to libmusepack I think).
Any more info in which case does it cause artifacts? More states should be saved not just frame length to be able to properly seek? Because for a mediaplayer the current non SeekTable solution is not really acceptable. |

Thanks for the original work of putting this library together. Hi Kuniklo, Very nice indeed... I do know the Rockbox firmware is written in C... I guess they would be interested for their iRiverport... I'm gonna notify the team and give them your link... Maybe editing the WIki over there with your link too... Regards, Tanguy |

Some files have huge frame dependencies. There's no way to know how much, so the fast seeking can break on any file randomly. So although it can be made to seek correctly on most of the files, it's not error-proof.
