avformat/matroskadec: fix handling of recursive SeekHead elements
When matroska_execute_seekhead() is called, it goes through the list of
seekhead entries and attempts to read elements not read yet. When doing
this, the parser can find further SeekHead elements, and will extend the
matroska->seekhead list. This can lead to a (practically) infinite loop
with certain broken files. (Maybe it can happen even with valid files.
The demuxer doesn't seem to check correctly whether an element has
already been read.)
Fix this by ignoring elements that were added to the seekhead field
during executing seekhead entries.
This does not fix the possible situation when multiple SeekHead elements
after the file header (i.e. occur after the "before_pos" file position)
point to the same elements. These elements will probably be parsed
multiple times, likely leading to bugs.
Fixes ticket #4162.

x11grab: Check the XQueryPointer return value
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.

libfdk-aacenc: Enable 7.1 channel encoding
7.1(wide) and 7.1(wide-side) channel layouts are supported in
fdk-aac since the 0.1.3 release.
The earlier versions of fdk-aac didn't include any library
version defines in the public headers, thus checking for
the AACENCODER_LIB_VL0 define is enough to know that we're
building against a new enough version of fdk-aac.
This change includes contributions by Tim Walker,
Michael Niedermayer and Timothy Gu.

http: add hack to make streams served by MediaGateway not seekable
These streams are reported as seekable, but all tests show they are not,
and the server merely pretends the streams are seekable. The server
responds with:
content-range: bytes 0-1999999999/2000000000
Range requests seem to be correctly answered, but the actual data
returned at the same offset is different. Assume this is a bug in the
server software. The server identifies itself as:
Server: MediaGateway 3.5.2-001
Add a hack that checks the server name, and disables seeking in this
case.

indicate that all others are present as well, since it can be used

lavd/v4l2: read the correct time per frame from devices that support a standard
Generally speaking, there are two types of v4l2 devices [1]:
1) devices that support a standard, like PAL or NTFS (tv cards, for example). For
this class of devices the framerate is fixed by the standard (for example PAL uses
25 fps) and the v4l2 driver cannot usually negotiate a different framerate (unless
it can skip frames on the driver side, to save I/O bandwidth).
2) devices for which the notion of standard does not make sense (webcams, for example).
For these devices it is usually possibile to request a desidered framerate.
In either case, the desidered frame rate can be requested when the VIDIOC_G_PARM
ioctl returns the V4L2_CAP_TIMEPERFRAME flag in the capability field.
Currently the code does not check for V4L2_CAP_TIMEPERFRAME and supports only the
second category of devices, returning a time per frame of 0/0 for devices in the
first group that do not permit to negotiate the framerate.
This patch adds support to read the correct framerate in all cases.
