It works the same as the 'tune' property that is used only to signal
the element that it should tune, but it is more natural to be used
as a signal rather than a property.
It is also proxied at the dvbbasebin element
ISDB-T and ISDB-Tb (the Brazilian variant) are the
terrestial DTV standards used by Japan, Philippines,
Maldives, Thailand, most South American countries
and Botswana. Changeset adds the set of previously
missing (and required) ISDB-T parameters, adapter
and frontend setup logic and proxies the new
properties on dvbbasebin.
Tested to work with the live aerial broadcast by
Tv Paraíba HD in Campina Grande (Brazil).

Allows proper tuning around high/low band boundaries when using
non "standard" LNBs.
Not all LNBs (Low noise block down converters) are made equal.
This is particularly true for universal LNBFs, where, even though
there are seemingly standard values for the local oscillator
frequencies, these can vary from manufacturer to manufacturer
and LNB model. Change also proxies the new LNB properties in
dvbbasebin.

Interestingly, Coverity implies that close takes an unsigned
argument, while my close(2) man page shows it taking a signed
argument. I guess it may be platforms specific.

New approach attempts to be more accurate by measuring
the elapsed time by iteration. Also:
* Use a 10 seconds default timeout and a half a second
polling step. New values should better match the tuning
process on real-life scenarios.
* Correct elapsed_time computation.
* Add _retry_ioctl() to avoid bailing out on temporary
ioctl EINTR failures (no need to check for EAGAIN cause
we are opening the frontend on blocking mode)
* Small corrections to fail condition handling
* Drop remaining sleep() logic in favor of polling
* Use best guess delivery system if none is set
* Make tuning/locking timeout configurable
* Add signals for tuning start, done and fail
* Drop gst_dvbsrc_frontend_status(). It was used only
for signal LOCK checking. This is now part of the
tuning/locking loop
* Break up frontend configuration and tuning
on separate functions
Plus:
* Add some more useful DEBUG/TRACE messages
* Move over misplaced DVB API message
* Fix wrong comment for default DVB buffer size (http://linuxtv.org/downloads/v4l-dvb-apis/dmx_fcalls.html#DMX_SET_BUFFER_SIZE)

c400eef377 introduced some defines to handle
older kernel headers. However, the check is done before the corresponding
kernel header (dvb/frontend.h) is included. As a result the macros are
always defined with results in 'redefined' errors with newer kernel
headers.
Move the check after the include to fix this.

-add delsys property
-add delivery system capability to the gstreamer adapter structure
-ready for add new delivery systems
Application must ask the adapter structure to know which delivery systems are avaible.
The property delsys must be set.

Which causes problems when used with _GNU_SOURCE apparently, and it
seems it was only set because of usleep(), which we can just replace
with g_usleep() until we get rid of those entirely.

Original code to parse satellite delivery descriptors to generate
"satellite" structures appeared to be copy & pasted from cable's code
without amending for satellite.
Also added 8PSK to dvbsrc's enum for modulation.

Make the _read_device function return a GstFlowReturn so that we can propagate
this to the caller. This allows us to differentiate between poll errors and
flushing state.
Fixes https://bugzilla.gnome.org/show_bug.cgi?id=674219
This allows to use much higher timeout values because GstPoll
is interruptible and keeps the number of wakeups during signal
loss lower.
Fixes bug #608171.

Some devices take a while to tune and 500ms was too short to detect
successful tuning. As well as waiting for 5 seconds each 100ms the
status is checked and the loop is broken out of when tuning has suceeded.

Actually use the code-rate-hp parameter for DVB-S.
It turns out setting to AUTO does not always work (
especially in diseq situations). Set by default to
FEC_AUTO.

Integrate SoC work done by Alessandro for the Freevo project.
Adds cam support to the dvb stack in GStreamer and a new
element (actually a bin) called dvbbasebin that integrates
dvbsrc and mpegtsparse to a) handle decryption and b) allow
acquiring multiple channels on same transponder without
knowing pid numbers.

Use _OBJECT macros where it makes sense.
