...to the BARK/MEL tables that these macros (from vorbis/scales.h) are trying to approximate? #define toBARK(f) (13.1*atan(.00074*(f))+2.24*atan((f)*(f)*1.85e-8)+1e-4*(f)) #define fromBARK(z) (102.*(z)-2.*pow(z,2.)+.4*pow(z,3)+pow(1.46,z)-1.) #define toMEL(f) (log(1.+(f)*.001)*1442.695) #define fromMEL(m) (1000.*exp((m)/1442.695)-1000.) I was wondering if I could come up with different functions that were easier to compute that would still be good approximations (also, can anyone comment on what a good metric is for judging the 'goodness' of an approximation function). Looking at a...

Hello there, we are among the last people to actually make use of the Ogg/Theora format. Ok, just kidding, but in fact we do live and archival streaming of various IT conferences. You can take a look at some here if you are interested: https://streaming.linux-magazin.de/en We are using several tools for live streaming, recording and editing Theora streams, among them ffmpeg2theora and oggCut

Hi there, we just encountered a problem with some tools obviously encoding into the skeleton format by default, which leads to problems with several other tools, in that particular case it's oggCut. When we try to edit/cut an ogg file with it, the program crashes with a segfault. I was able to locate and fix the problem in the oggCut source but I am wondering how to convert my ogg files to a

I've just built libguestfs (from git) on Ubuntu 13.10 and it worked for me. Here's what I did: * Clone libguestfs from git: git clone https://github.com/libguestfs/libguestfs.git cd libguestfs * Create a file called 'localconfigure' containing: ---------------------------------------------------------------------- . localenv ./autogen.sh \ --prefix /usr \ --libdir /usr/lib

...e: virt-builder: error: virt-resize failed Upon further investigation it turns out that there's a kernel panic when booting the freshly created image. Running the test-tool gives the following output: -------------------------------------------------------------------- LIBGUESTFS_PATH=/home/ofrommel/libguestfs-1.24.1/appliance LIBGUESTFS_CACHEDIR=/home/ofrommel/libguestfs-1.24.1/tmp LD_LIBRARY_PATH=/home/ofrommel/libguestfs-1.24.1/ruby/ext/guestfs:/home/ofrommel/libguestfs-1.24.1/src/.libs:/home/ofrommel/libguestfs-1.24.1/gobject/.libs LIBGUESTFS_TMPDIR=/home/ofrommel/libguestfs-1.24.1/tmp PAT...

Dammit, you are fast! I just tried to figure out what's missing from running "init" on the host and installing the missing packages, among them "mdadm" and others. Also I noticed that "appliance/packagelist" includes a lot of packages that aren't available on Ubuntu, but maybe that doesn't matter. Anyway, I tried your solution but still get the kernel
