Description
|
2016-06-30 21:18:56 +08:00
|
|
|
===========
|
|
|
|
|
|
|
|
|
|
To query the attributes of a tuner applications initialize the ``index``
|
|
|
|
|
field and zero out the ``reserved`` array of a struct
|
2016-08-30 04:37:59 +08:00
|
|
|
:c:type:`v4l2_tuner` and call the ``VIDIOC_G_TUNER`` ioctl
|
2016-06-30 21:18:56 +08:00
|
|
|
with a pointer to this structure. Drivers fill the rest of the structure
|
2016-07-03 22:53:09 +08:00
|
|
|
or return an ``EINVAL`` error code when the index is out of bounds. To
|
2016-06-30 21:18:56 +08:00
|
|
|
enumerate all tuners applications shall begin at index zero,
|
2016-07-03 22:53:09 +08:00
|
|
|
incrementing by one until the driver returns ``EINVAL``.
|
2016-06-30 21:18:56 +08:00
|
|
|
|
|
|
|
|
Tuners have two writable properties, the audio mode and the radio
|
|
|
|
|
frequency. To change the audio mode, applications initialize the
|
|
|
|
|
``index``, ``audmode`` and ``reserved`` fields and call the
|
|
|
|
|
``VIDIOC_S_TUNER`` ioctl. This will *not* change the current tuner,
|
|
|
|
|
which is determined by the current video input. Drivers may choose a
|
|
|
|
|
different audio mode if the requested mode is invalid or unsupported.
|
|
|
|
|
Since this is a write-only ioctl, it does not return the actually
|
|
|
|
|
selected audio mode.
|
|
|
|
|
|
|
|
|
|
:ref:`SDR <sdr>` specific tuner types are ``V4L2_TUNER_SDR`` and
|
|
|
|
|
``V4L2_TUNER_RF``. For SDR devices ``audmode`` field must be initialized
|
|
|
|
|
to zero. The term 'tuner' means SDR receiver in this context.
|
|
|
|
|
|
|
|
|
|
To change the radio frequency the
|
2016-07-02 00:42:29 +08:00
|
|
|
:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl is available.

change, for example with the current video standard.
|

|
|

When the structure refers to a radio tuner the

``V4L2_TUNER_CAP_LANG1``, ``V4L2_TUNER_CAP_LANG2`` and

Some tuners or audio decoders can determine the received audio

subprograms by analyzing audio carriers, pilot tones or other
|
|
|
|
|
indicators. To pass this information drivers set flags defined in
|
|
|

|
:ref:`tuner-rxsubchans` in this field. For example:

|
|

|
* -
|

|
|
|
|
|
- ``V4L2_TUNER_SUB_MONO``

|
|
|
|
- ``STEREO | SAP``
|
|
|
|
|

|
|
|
|
|

|
|
|

When the ``V4L2_TUNER_CAP_STEREO``, ``_LANG1``, ``_LANG2`` or
|
|
|
|
|
``_SAP`` flag is cleared in the ``capability`` field, the

|

corresponding ``V4L2_TUNER_SUB_`` flag must not be set here.
|
|
|
|

|
|
|

This field is valid only if this is the tuner of the current video

The selected audio mode, see :ref:`tuner-audmode` for valid
|
|
|
|
|
values. The audio mode does not affect audio subprogram detection,
|
|
|
|
|
and like a :ref:`control` it does not automatically
|
|
|
|
|
change unless the requested mode is invalid or unsupported. See
|
|
|
|
|
:ref:`tuner-matrix` for possible results when the selected and
|
|
|
|
|
received audio programs do not match.
|
|
|
|
|
|
|
|
|
|
Currently this is the only field of struct

struct :c:type:`v4l2_tuner` applications can change.

|
|
|
|
* - __u32
|

|
|
|
|
|
- :cspan:`1` The signal strength if known.
|
|
|

Ranging from 0 to 65535. Higher values indicate a better signal.

- ``afc``
|
|
|
|
|
- :cspan:`1` Automatic frequency control.
|
|
|
|
|
|
|
|
|
|
When the ``afc`` value is negative, the frequency is too

low, when positive too high.

[media] docs-rst: add tabularcolumns to all tables
LaTeX doesn't handle too well auto-width on tables, and ReST
markup requires an special tag to give it the needed hints.
As we're using A4 paper, we have 17cm of useful spaces. As
most media tables have widths, let's use it to generate the
needed via the following perl script:
my ($line_size, $table_header, $has_cols) = (17.5, 0, 0);
my $out;
my $header = "";
my @widths = ();
sub round { $_[0] > 0 ? int($_[0] + .5) : -int(-$_[0] + .5) }
while (<>) {
if (!$table_header) {
$has_cols = 1 if (m/..\s+tabularcolumns::/);
if (m/..\s+flat-table::/) {
$table_header = 1;
$header = $_;
next;
}
$out .= $_;
next;
}
$header .= $_;
@widths = split(/ /, $1) if (m/:widths:\s+(.*)/);
if (m/^\n$/) {
if (!$has_cols && @widths) {
my ($tot, $t, $i) = (0, 0, 0);
foreach my $v(@widths) { $tot += $v; };
$out .= ".. tabularcolumns:: |";
for ($i = 0; $i < scalar @widths - 1; $i++) {
my $v = $widths[$i];
my $w = round(10 * ($v * $line_size) / $tot) / 10;
$out .= sprintf "p{%.1fcm}|", $w;
$t += $w;
}
my $w = $line_size - $t;
$out .= sprintf "p{%.1fcm}|\n\n", $w;
}
$out .= $header;
$table_header = 0;
$has_cols = 0;
$header = "";
@widths = ();
}
}
print $out;

[media] docs-rst: add tabularcolumns to all tables
LaTeX doesn't handle too well auto-width on tables, and ReST
markup requires an special tag to give it the needed hints.
As we're using A4 paper, we have 17cm of useful spaces. As
most media tables have widths, let's use it to generate the
needed via the following perl script:
my ($line_size, $table_header, $has_cols) = (17.5, 0, 0);
my $out;
my $header = "";
my @widths = ();
sub round { $_[0] > 0 ? int($_[0] + .5) : -int(-$_[0] + .5) }
while (<>) {
if (!$table_header) {
$has_cols = 1 if (m/..\s+tabularcolumns::/);
if (m/..\s+flat-table::/) {
$table_header = 1;
$header = $_;
next;
}
$out .= $_;
next;
}
$header .= $_;
@widths = split(/ /, $1) if (m/:widths:\s+(.*)/);
if (m/^\n$/) {
if (!$has_cols && @widths) {
my ($tot, $t, $i) = (0, 0, 0);
foreach my $v(@widths) { $tot += $v; };
$out .= ".. tabularcolumns:: |";
for ($i = 0; $i < scalar @widths - 1; $i++) {
my $v = $widths[$i];
my $w = round(10 * ($v * $line_size) / $tot) / 10;
$out .= sprintf "p{%.1fcm}|", $w;
$t += $w;
}
my $w = $line_size - $t;
$out .= sprintf "p{%.1fcm}|\n\n", $w;
}
$out .= $header;
$table_header = 0;
$has_cols = 0;
$header = "";
@widths = ();
}
}

- This is a multi-standard tuner; the video standard can or must be

switched. (B/G PAL tuners for example are typically not considered
|
|
|
|
|
multi-standard because the video standard is automatically

determined from the frequency band.) The set of supported video

where the seek stops when it reaches the end of the frequency

range.

- 0x0040
|
|
|
|
|
- Reception of the primary language of a bilingual audio program is

supported. Bilingual audio is a feature of two-channel systems,
|
|
|
|
|
transmitting the primary language monaural on the main audio
|
|
|
|
|
carrier and a secondary language monaural on a second carrier.
|

Only ``V4L2_TUNER_ANALOG_TV`` tuners can have this capability.

standard. Two audio carriers are available for mono or stereo
|
|

[media] docs-rst: add tabularcolumns to all tables
LaTeX doesn't handle too well auto-width on tables, and ReST
markup requires an special tag to give it the needed hints.
As we're using A4 paper, we have 17cm of useful spaces. As
most media tables have widths, let's use it to generate the
needed via the following perl script:
my ($line_size, $table_header, $has_cols) = (17.5, 0, 0);
my $out;
my $header = "";
my @widths = ();
sub round { $_[0] > 0 ? int($_[0] + .5) : -int(-$_[0] + .5) }
while (<>) {
if (!$table_header) {
$has_cols = 1 if (m/..\s+tabularcolumns::/);
if (m/..\s+flat-table::/) {
$table_header = 1;
$header = $_;
next;
}
$out .= $_;
next;
}
$header .= $_;
@widths = split(/ /, $1) if (m/:widths:\s+(.*)/);
if (m/^\n$/) {
if (!$has_cols && @widths) {
my ($tot, $t, $i) = (0, 0, 0);
foreach my $v(@widths) { $tot += $v; };
$out .= ".. tabularcolumns:: |";
for ($i = 0; $i < scalar @widths - 1; $i++) {
my $v = $widths[$i];
my $w = round(10 * ($v * $line_size) / $tot) / 10;
$out .= sprintf "p{%.1fcm}|", $w;
$t += $w;
}
my $w = $line_size - $t;
$out .= sprintf "p{%.1fcm}|\n\n", $w;
}
$out .= $header;
$table_header = 0;
$has_cols = 0;
$header = "";
@widths = ();
}
}
print $out;

media: fix pdf build with Spinx 1.6
Sphinx 1.6 generates some LaTeX code before each table,
starting its own environment before calling tabulary,
apparently to improve table layout.
The problem is that such environment is incompatible with
adjustbox. While, in thesis, it should be possible to override
it or to redefine tabulary, I was unable to produce such patch.
Also, that would likely break on some future Sphinx version.
So, instead, let's just change the font size on bigger tables,
in order for them to fit into the page size. That is not as
good as adjustbox, and require some manual work, but it should
be less sensitive to Sphinx changes.
While here, adjust a few other tables whose text is exceeding
the cell boundaries.

Playback of both languages in ``MODE_STEREO`` is deprecated. In the
|
|
|
|
|
future drivers should produce only the primary language in this mode.
|
|
|
|
|
Applications should request ``MODE_LANG1_LANG2`` to record both
|
|
|
|
|
languages or a stereo signal.
