x11grab: Check XFixesGetCursorImage return value
Conflicts:
libavdevice/x11grab.c
See: a65c0a3fe8
The warning with adjusted text is kept from a65c0a3fe8
but drawing the cursor is not disabled in case XFixesGetCursorImage() fails
Merged-by: Michael Niedermayer <michaelni@gmx.at>
The paint_mouse_pointer() code uses XFixes to retrieve the cursor
coordinates, but XFixes gives no information about which screen the
pointer is on; this results in always drawing the cursor on the
captured screen even if the mouse pointer was on another screen.
For example, when capturing from screen 1 (i.e. -f x11grab -i ":0.1")
the cursor was being drawn in the captured image even when the mouse
pointer was actually on screen 0, which is wrong and visually confusing.

As of September 14 2012, v4l_enumstd() will return ENODATA
when a device's std field is set to 0. That is, the device
does not have a standard format. In order to properly
handle this case, v4l2_set_parameters should catch the
ENODATA code and break instead of failing.
Below is the v4l2-core commit describing this change.

The X11 servers by VNC, at 32-bits depths, has the following masks:

This is not compatible with AV_PIX_FMT_0RGB32, and the result
is success with completely wrong colors.
MSVC does not allow passing file pointers between libs
This API can thus not work with MSVC and as it was very recently added
and its it was in no release its removial should not cause any problems

Whenever av_gettime() is used to measure relative period of time,
av_gettime_relative() is prefered as it guarantee monotonic time
on supported platforms.
Since v4l2 is compiled only on Linux where av_gettime_relative()
is monotonic, a small wrapper function av_gettime_monotonic() is used
(should be inlined the compiler) to put emphasis on that fact.

Based on original code by Christophe Gisquet in 2010, updated to work
with current ffmpeg APIs.
Supports grabbing a single window or an area of the screen, including
support for multiple monitors (Windows does funky stuff with negative
coordinates here).
I've moved most of the configuration to AVOptions; the input file name
is now only the string "desktop", or "title=<windowname>" to select a
single window. The AVOptions are the same as x11grab where possible.
Code has been added to support a "show_region" mode, like x11grab, which
will draw a rectangle on the screen around the area being captured.
Instead of duplicating code for paletted image handling, I make use of
the GDI API's ability to output DIB (BMP) images, which can be run
through ffmpeg's existing BMP decoder.
