sachih / camunits Goto Github PK

What steps will reproduce the problem?
1. try to run camview
2. camview aborts with "GThread-ERROR **: GThread system may only be
initialized once."

What version of the product are you using? On what operating system?
Confirmed against SVN or 3.0.0, running Ubuntu Linux 9.10 with many extra
packages.

Please provide any additional information below.
I don't know why gthread is being initialized multiple times, but wrapping
with a simple check for whether it's already been initialized fixed the
problem on my machine.

What steps will reproduce the problem?
1. Create a float control from range 0.1 to 60
2. View results using (eg) camview
3. Note that you can only see integer values.

camunits attempts to set display_width  and display_prec to sane values
automatically, but may not always succeed.  display_width and display_prec
are private variables with no setters.  The attached patch provides setters
for them.  Apologies if this is NOTABUG or there is another better way of
doing this.

The convert.colorspace plugin does not currently support the IYU1/YUV411
colorspace.  The attached patch against SVN HEAD adds support to the plugin
and adds supporting functions to pixels.[ch].  The functions were derived
from the existing YUV422 / YUYV plugin, and follow a similar pattern.

Problem:
  I am writing a plugin to interface with an external library.  The
external library requires that a function { CameraLibraryInitialize() } get
called on startup, before any other functions are called.  This fits nicely
into the cam_plugin_initialize() call.  The library also provides a
function to be called on cleanup, {CameraLibraryUninitialize() } but there
does not seem to be a place to call such a function.

Workaround:
  Via the glib documentation, I've found that I can simply place the
appropriate call in a function named g_module_unload() and this has the
desired effect.  It may be cleaner to have a cam_plugin_finalize() to
complement cam_plugin_initialize(), however?

What steps will reproduce the problem?
1. call cam_pixel_bayer_interpolate_to_8u_bgra

What version of the product are you using? On what operating system?
