demux, stream: remove unneeded crap (esp. optical discs and Linux TV)

Browse Source 
I don't ever use them, so kill them.

Linux TV is excessively complex, and whenever I attempted to use it, it
didn't work well or would have required some major work to update it.
(For example, when I tried to use a webcam-type device with tv://, it
worked badly; even the libavdevice garbage worked better.)

The "program" property was rather complex and rather obscure. I didn't
ever use it. Should there ever be a proper use for it (maybe HLS stream
selection?), it should be rewritten anyway.

Disc Devices
------------
``--cdrom-device=<path>``
Specify the CD-ROM device (default: ``/dev/cdrom``).
``--dvd-device=<path>``
Specify the DVD device or .iso filename (default: ``/dev/dvd``). You can
also specify a directory that contains files previously copied directly
from a DVD (with e.g. vobcopy).
.. admonition:: Example
``mpv dvd:// --dvd-device=/path/to/dvd/``
``--bluray-device=<path>``
(Blu-ray only)
Specify the Blu-ray disc location. Must be a directory with Blu-ray
structure.
.. admonition:: Example
``mpv bd:// --bluray-device=/path/to/bd/``
``--cdda-...``
These options can be used to tune the CD Audio reading feature of mpv.
``--cdda-speed=<value>``
Set CD spin speed.
``--cdda-paranoia=<0-2>``
Set paranoia level. Values other than 0 seem to break playback of
anything but the first track.
:0: disable checking (default)
:1: overlap checking only
:2: full data correction and verification
``--cdda-sector-size=<value>``
Set atomic read size.
``--cdda-overlap=<value>``
Force minimum overlap search during verification to <value> sectors.
``--cdda-toc-bias``
Assume that the beginning offset of track 1 as reported in the TOC
will be addressed as LBA 0. Some discs need this for getting track
boundaries correctly.
``--cdda-toc-offset=<value>``
Add ``<value>`` sectors to the values reported when addressing tracks.
May be negative.
``--cdda-skip=<yes|no>``
(Never) accept imperfect data reconstruction.
``--cdda-cdtext=<yes|no>``
Print CD text. This is disabled by default, because it ruins performance
with CD-ROM drives for unknown reasons.
``--dvd-speed=<speed>``
Try to limit DVD speed (default: 0, no change). DVD base speed is 1385
kB/s, so an 8x drive can read at speeds up to 11080 kB/s. Slower speeds
make the drive more quiet. For watching DVDs, 2700 kB/s should be quiet and
fast enough. mpv resets the speed to the drive default value on close.
Values of at least 100 mean speed in kB/s. Values less than 100 mean
multiples of 1385 kB/s, i.e. ``--dvd-speed=8`` selects 11080 kB/s.
.. note::
You need write access to the DVD device to change the speed.
``--dvd-angle=<ID>``
Some DVDs contain scenes that can be viewed from multiple angles.
This option tells mpv which angle to use (default: 1).

``--tv-...``
These options tune various properties of the TV capture module. For
watching TV with mpv, use ``tv://`` or ``tv://<channel_number>`` or
even ``tv://<channel_name>`` (see option ``tv-channels`` for ``channel_name``
below) as a media URL. You can also use ``tv:///<input_id>`` to start
watching a video from a composite or S-Video input (see option ``input`` for
details).
``--tv-device=<value>``
Specify TV device (default: ``/dev/video0``).
``--tv-channel=<value>``
Set tuner to <value> channel.
``--no-tv-audio``
no sound
``--tv-automute=<0-255> (v4l and v4l2 only)``
If signal strength reported by device is less than this value, audio
and video will be muted. In most cases automute=100 will be enough.
Default is 0 (automute disabled).
``--tv-driver=<value>``
See ``--tv=driver=help`` for a list of compiled-in TV input drivers.
available: dummy, v4l2 (default: autodetect)
``--tv-input=<value>``
Specify input (default: 0 (TV), see console output for available
inputs).
``--tv-freq=<value>``
Specify the frequency to set the tuner to (e.g. 511.250). Not
compatible with the channels parameter.
``--tv-outfmt=<value>``
Specify the output format of the tuner with a preset value supported
by the V4L driver (YV12, UYVY, YUY2, I420) or an arbitrary format given
as hex value.
``--tv-width=<value>``
output window width
``--tv-height=<value>``
output window height
``--tv-fps=<value>``
framerate at which to capture video (frames per second)
``--tv-buffersize=<value>``
maximum size of the capture buffer in megabytes (default: dynamical)
``--tv-norm=<value>``
See the console output for a list of all available norms.
See also: ``--tv-normid``.
``--tv-normid=<value> (v4l2 only)``
Sets the TV norm to the given numeric ID. The TV norm depends on the
capture card. See the console output for a list of available TV norms.
``--tv-chanlist=<value>``
available: argentina, australia, china-bcast, europe-east,
europe-west, france, ireland, italy, japan-bcast, japan-cable,
newzealand, russia, southafrica, us-bcast, us-cable, us-cable-hrc
``--tv-channels=<chan>-<name>[=<norm>],<chan>-<name>[=<norm>],...``
Set names for channels.
.. note::
If <chan> is an integer greater than 1000, it will be treated as
frequency (in kHz) rather than channel name from frequency table.
Use _ for spaces in names (or play with quoting ;-) ). The channel
names will then be written using OSD, and the input commands
``tv_step_channel``, ``tv_set_channel`` and ``tv_last_channel``
will be usable for a remote control. Not compatible with
the ``frequency`` parameter.
.. note::
The channel number will then be the position in the 'channels'
list, beginning with 1.
.. admonition:: Examples
``tv://1``, ``tv://TV1``, ``tv_set_channel 1``,
``tv_set_channel TV1``
``--tv-[brightness|contrast|hue|saturation]=<-100-100>``
Set the image equalizer on the card.
``--tv-audiorate=<value>``
Set input audio sample rate.
``--tv-forceaudio``
Capture audio even if there are no audio sources reported by v4l.
``--tv-alsa``
Capture from ALSA.
``--tv-amode=<0-3>``
Choose an audio mode:
:0: mono
:1: stereo
:2: language 1
:3: language 2
``--tv-forcechan=<1-2>``
By default, the count of recorded audio channels is determined
automatically by querying the audio mode from the TV card. This option
allows forcing stereo/mono recording regardless of the amode option
and the values returned by v4l. This can be used for troubleshooting
when the TV card is unable to report the current audio mode.
``--tv-adevice=<value>``
Set an audio device. <value> should be ``/dev/xxx`` for OSS and a
hardware ID for ALSA. You must replace any ':' by a '.' in the
hardware ID for ALSA.
``--tv-audioid=<value>``
Choose an audio output of the capture card, if it has more than one.
``--tv-[volume|bass|treble|balance]=<0-100>``
These options set parameters of the mixer on the video capture card.
They will have no effect, if your card does not have one. For v4l2 50
maps to the default value of the control, as reported by the driver.
``--tv-gain=<0-100>``
Set gain control for video devices (usually webcams) to the desired
value and switch off automatic control. A value of 0 enables automatic
control. If this option is omitted, gain control will not be modified.
``--tv-immediatemode=<bool>``
A value of 0 means capture and buffer audio and video together. A
value of 1 (default) means to do video capture only and let the audio
go through a loopback cable from the TV card to the sound card.
``--tv-mjpeg``
Use hardware MJPEG compression (if the card supports it). When using
this option, you do not need to specify the width and height of the
output window, because mpv will determine it automatically from
the decimation value (see below).
``--tv-decimation=<1|2|4>``
choose the size of the picture that will be compressed by hardware
MJPEG compression:
:1: full size
- 704x576 PAL
- 704x480 NTSC
:2: medium size
- 352x288 PAL
- 352x240 NTSC
:4: small size
- 176x144 PAL
- 176x120 NTSC
``--tv-quality=<0-100>``
Choose the quality of the JPEG compression (< 60 recommended for full
size).
``--tv-scan-autostart``
Begin channel scanning immediately after startup (default: disabled).
``--tv-scan-period=<0.1-2.0>``
Specify delay in seconds before switching to next channel (default:
0.5). Lower values will cause faster scanning, but can detect inactive
TV channels as active.
``--tv-scan-threshold=<1-100>``
Threshold value for the signal strength (in percent), as reported by
the device (default: 50). A signal strength higher than this value will
indicate that the currently scanning channel is active.

``--dvbin-card=<1-4>``
Specifies using card number 1-4 (default: 1).
``--dvbin-file=<filename>``
Instructs mpv to read the channels list from ``<filename>``. The default is
in the mpv configuration directory (usually ``~/.config/mpv``) with the
filename ``channels.conf.{sat,ter,cbl,atsc}`` (based on your card type) or
``channels.conf`` as a last resort.
For DVB-S/2 cards, a VDR 1.7.x format channel list is recommended
as it allows tuning to DVB-S2 channels, enabling subtitles and
decoding the PMT (which largely improves the demuxing).
Classic mplayer format channel lists are still supported (without
these improvements), and for other card types, only limited VDR
format channel list support is implemented (patches welcome).
For channels with dynamic PID switching or incomplete
``channels.conf``, ``--dvbin-full-transponder`` or the magic PID
``8192`` are recommended.
``--dvbin-timeout=<1-30>``
Maximum number of seconds to wait when trying to tune a frequency before
giving up (default: 30).
``--dvbin-full-transponder=<yes|no>``
Apply no filters on program PIDs, only tune to frequency and pass full
transponder to demuxer.
The player frontend selects the streams from the full TS in this case,
so the program which is shown initially may not match the chosen channel.
Switching between the programs is possible by cycling the ``program``
property.
This is useful to record multiple programs on a single transponder,
or to work around issues in the ``channels.conf``.
It is also recommended to use this for channels which switch PIDs
on-the-fly, e.g. for regional news.
Default: ``no``

This works as follows:

- demux_rar.c detects it
