Thanks for the bug report.
None of these issues are Debian specific and hence are probably
better addressed in the upstream projects bug tracker:
https://github.com/erikd/libsndfile/
- Ogg/Vorbis: vorbis_metatypes is lacking:
{ SF_STR_TRACKNUMBER, Tracknumber },
{ SF_STR_GENRE, Genre },
I raised this:
https://github.com/erikd/libsndfile/issues/87
- Wav:
wav.c:308 has:
if (psf-filelength SF_PLATFORM_S64 (0x))
psf_log_printf (psf, Warning : filelength 0x. This
is bad\n) ;
But for non-seekable files, filelength is set to SF_COUNT_MAX which
is 0x, so this produces a bogus warning e.g. when doing:
cat somefile.wav | sndfile-info -
https://github.com/erikd/libsndfile/issues/88
- Voc:
snip
The first error is clearly bogus because if it could not open the
file how could it (correctly) determine the length, samplerate etc.?
OK, that's just a problem with the formulation of the message
(open != parse).
Open means that libsndfile's sf_open() function returns a non-NULL
pointer as documented here:
http://www.mega-nerd.com/libsndfile/api.html#open
But the second error is the real problem. It claims there is an
error in the file. However, this is an original file recorded with
original recorder software from Creative Labs on a Dos system some
20 years ago. (I just purged the samples because it was a private
recording and for compressibility ;), the error was the same before
and after.)
An error is returned when libsndfile cannot correctly open the file.
Is that not an error?
Looking at the code (voc.c:256) and also at the strace output, it
doesn't even check more than one section to determine whether
they're incompatible (whatever that means -- I guess sections with
different sample rates might qualify), just gives this message after
finding there's more than one section!?
A couple of points here:
* VOC is a format that has not been in widespread use for over a decade.
* libsndfile does not handle *any* formats with more than one section.
I don't really understand what's up here. Either this is unfinished
code without the appropriate WIP warning,
Err, can you actually name one piece of non-trivial software that is
actually finished? All software is a WIP, and that is especially so
for most Open Source projects.
or the message is really
meant to say: Sorry, this library supports VOC files with one
section only, in which case the accusation Error in VOC file is
not a good way to put that.
If you look in the code you will find that Error in VOC file is
an error that can occur in a number of situations. Error reporting
is difficult.
Since none of these issues are Debian specific, I suggest you
close this bug and follow the tickets on github.
