## Fixing a few bugs. For more information than those provided below please
## see the related file: 'patches/patches.README'.

# 1) Fix bug caused by a deprecated page size setting of 'GtkSpinButton' in
# function 'gtk_adjustment_new'. The bug triggers error messages when video
# encoding is switched to OGG/Theora (i.e. one message for each related spin
# button).
patch src/settings_dialog.c < $PTC/ucview-0.33-deprecated_Gtk_setting.patch

# 2) Fix bug caused by UCView not being able to create a directory for plugins
# when the parent directory '.ucview' is not already there (e.g. when the box
# in the 'Select device' window was not checked at least once).
patch src/plugin_loader.c < $PTC/ucview-0.33-plugins_mkdir_parents.patch

# 3) Fix bug caused by the path for captured video files being set by default
# to NULL, thus not allowing to save anything unless it is set explicitly.
patch src/callbacks.c < $PTC/ucview-0.33-default_video_path.patch

# 4) Something similar to 3) happens to the path for image files as well.
patch src/ucview-window.c < $PTC/ucview-0.33-default_image_path.patch
