FlacBox decoding problems

[endian]

There is a quite capable C* FLAC code library at https://github.com/VirusFree/FlacBox

I have started using this to create a music analysis package (checking clipping dynamic range, etc).

However, when running it on the flac files a few files (50 out of 13500) fail while decoding, ending in a FlacBox assert instead.

If I rip the same CDs using FlacBox they decode just fine.

Details are described below and at this link: https://github.com/VirusFree/FlacBox/issues/1

I am currently trying to find out if this is due to some problem in FlacBox or some problem in dbPoweramp.

Any info on this subject would be appreciated.

Thanks in advance, Kenneth

================================================

Hi,

I am working on a program for analyzing sound level, dynamics and clipping in any music library. For this I am using the FlacBox code.

However, I receive a few types of FlacExceptions when reading certain flac files:

The files were ripped using a recent version of dbPoweramp (15.2.0.3), and I ran over 10000 files, and around 50 failed with the following errors.

Exception:FlacBox.FlacException: Invalid subframe coefficient precision
Exception:FlacBox.FlacException: Subframe type is set to reserved=17
Exception:FlacBox.FlacException: Subframe type is set to reserved=18
Exception:FlacBox.FlacException: Subframe type is set to reserved=4
Exception:FlacBox.FlacException: Unexpected end of stream: bit reader needs data
Exception:FlacBox.FlacException: Zeros expected for alignment padding

I have tried re-ripping most of the files in dbPoweramp, but the results are the same afterwards.

I am currently trying to find out if this is due to a dbPoweramp problem or if it is a problem in FlacBox.

Please help me in pinpointing it!

Regards, Kenneth

Re: FlacBox decoding problems

It is likely that this decoder does not work with the latest flac encoding.

We only use the offical flac libraries to encode, so the issue will be with your decoder.
