In 2007, user reported a segfault in FLAC::Encoder::File::progress_callback() when called from ~Stream(). Original report at https://sourceforge.net/p/flac/bugs/256/ Hello! Sorry, english is not my best language. I use libFLAC++ API. I have some problems. In libFLAC API all OK.

(2) OCaml bindings to the callback. (3) Perl bindings to the callback. Rich. -- Richard Jones, Virtualization Group, Red Hat

This is an updated and extended version of the original patch: https://www.redhat.com/archives/libguestfs/2010-August/msg00163.html This adds OCaml and Perl bindings (both tested), support for progress bars in virt-resize, and adds progress notifications to a number of the simpler commands. Still to do is to add progress messages to more commands. There are still a few commands which would be

Allow Guestfs.t handle to be garbage collected, and add a regression test.

This patch set fixes a two year old bug in guestfish, namely that the 'glob' command does not expand /dev/* patterns. https://bugzilla.redhat.com/show_bug.cgi?id=635971 Rich.

Hi, In the last days I've been taking as reference the example found in examples/c/encode/file/main.c. With it I've been able to encode a 2ch, 16 bps, 44100 sample rate input WAV file to a FLAC file. Now I've been trying to modify this example to encode a 2ch, 24 bps, 96000 sample rate WAV file. I have to say I'm a bit lost on how I should read the input file in this case, and
