Fixes#621723 (partially)
set_caps can fail if the video device is running, in that case
setting its format leads to EBUSY.
If set_caps fails then we will not have set up the buffer pool
(it will be NULL) which leads to a crash when we try to pull
buffers. If we fail the negotiate on set_caps failure, then we
won't go to playing state and won't crash.
This is a small improvement. Of course, a nicer fix would
be to make set_caps work in the case where the format is
unchanged. If the format has changed, failing is
probably correct because we need to close the device
(go to NULL state) in order to set caps.
"Low" etc. are quality settings here (e.g. for the internal resampler).
Some day when we use GLib's i18n functions we might want to use
NC_() and g_dpgettext2() here instead of the comments.
Fixes#555967.
OSS4 supports per-stream volume control, so expose this using the right
API, so that playbin2 and applications like totem can make use of it
(instead of using a volume element for volume control).
Fixes#614305.
When iterating the formats table, we can just pass the whole
entry to our helper function, which avoids iterating the table
again to find the entry structure from the passed format id.
Also accept formats that are not natively supported by the
hardware, OSS4 can convert them internally. List the native
formats first in the caps though, to express our preference
for the native formats. We need this in order to support the
case properly where the audio hardware supports only e.g.
little endian PCM, but the host is big endian, since many
audio elements only support native endianness and make the
reasonable assumption that any audiosink will be able to
handle audio in native endianness.

Fixes#614317.
A side effect is that it passes -Wformat-nonliteral and doesn't read
invalid memory in some cases, like when the mixer track contains
a % sign or there is a number but not a known mixer name.
Code cleanups, general improvements, support for the
new mixer flags in latest gst-plugins-base.

Apparently mono sliders have the mono value repeated in the upper bits,
so mask those out when reading them. Probably makes the mixer applet
work properly in some more cases.
Instead of using BaseSrc default format GST_FORMAT_BYTES, send it in
GST_FORMAT_TIME.

Fixes#611659
The compiler wants a cast here even though the type is already
typedefed as 64-bit integer (presumably because glib has typedefed
guint64 to unsigned long here).
Don't leak a string everytime get_uri() is called and a device
has been set. There's a limited number of devices, so just
intern the string instead of doing more elaborate housekeeping
and storing it in the instance struct or so.
Old videodevice2.h kernel headers used ioctl stuff without
including ioctl.h, making compilation fail on older systems.
Note: Including ioctl.h here is only a workaround for old kernel
headers, should be removed once everybody has new enough headers.
Fixes bug #597867.
For cameras/drivers that don't support e.g. VIDIOC_G_PARM we'd end up without
a framerate and would try to divide by 0, causing run-time warnings and all
frames to be timestamped with 0, which makes sinks that sync against the clock
drop them, causing 'hangs' (observed with the pwc driver and a Logitech QuickCam
Pro 4000). So if we do not know the framerate, simply don't adjust the
timestamps. Fixes#591451.
Clear format list and probed caps when going to NULL so if a new device
is set we'll probe the formats again instead of using previously
detected ones. Fixes bug #591747.
It seems to cause strange occasional high latencies (almost 200ms) when dequeuing buffers from _buffer_alloc(). It is simpler and seems to work much better to dqbuf from the same thread that is queuing the next buffer.
This also does the following changes:
(1) pull the bufferpool code out into gstv4l2bufferpool.c, and make a
bit more generic so it can be used both for v4l2src and v4l2sink
(2) move some of the device probing/configuration/caps stuff into
gstv4l2object.c so it does not have to be duplicated between
v4l2src and v4l2sink
Fixes bug #590280.
The v4l2 driver for USB webcams on OpenSolaris does not support select()
calls. Detect when select() fails, and skip polling the device afterward,
which restores the pre 0.10.14 behaviour on OpenSolaris.

We need a cast here for pointer arithmetic to work correctly, but some
MSVC versions don't seem to like 'byte', so use guint8 here. Hopefully
fixes#585361.
Fix the setting of toggle switches on some broken audio drivers which
report that no audio ports are settable by ignoring the mod_port field
there.
Add some debug statements.
Fix a FIXME now that Good relies on a new enough gst-plugins-base.
Use new audio mixer flags added in Base 0.10.23 to expose flags and options
on the SunAudio devices.
