Sony TV HDMI input detection

[axxelh]

Issue 202 added HDMI input info, but that doesn't appear to work on current Sony Android TV implementations.

This command appears to work on my X950H, returning just the port number (ports are 1 indexed, when the routing is 0x0000 internal apps are in use).:

'dumpsys hdmi_control | grep -o 'mActiveRoutingPath: 0x[1-9]' | grep -o [1-9]'

There are several other fields in dumpsys that could be used, but this seemed cleanest to me.

Not sure what the right pattern is for multiple variants of CMD_HDMI_INPUT or detection of subtypes of Android TV so I'm not proposing a patch.

There’s a method for getting device properties:

python-androidtv/androidtv/basetv/basetv_sync.py

Lines 185 to 193 in 88dab23

	def get_device_properties(self):
	"""Return a dictionary of device properties.
	Returns
	-------
	props : dict
	A dictionary with keys ``'wifimac'``, ``'ethmac'``, ``'serialno'``, ``'manufacturer'``, ``'model'``, and ``'sw_version'``
	"""

Rather than simply returning the dictionary of device properties, I think it should also store that dictionary. Then other methods could check the device properties and adjust their ADB commands accordingly, similar to how Google TV support is handled. For example, from get_properties():

python-androidtv/androidtv/androidtv/androidtv_sync.py

Line 129 in 88dab23

output = self._adb.shell(constants.CMD_ANDROIDTV_PROPERTIES_LAZY_RUNNING_APPS if not self._is_google_tv else constants.CMD_GOOGLE_TV_PROPERTIES_LAZY_RUNNING_APPS)

With the latest changes that I made, you can customize commands based on the device info. For example, see here:

python-androidtv/androidtv/androidtv/base_androidtv.py

Line 48 in e12aff4

self._cmd_current_app = constants.CMD_CURRENT_APP_GOOGLE_TV

You could add a _cmd_hdmi_input attribute and customize it for applicable Sony devices.

@axxelh I checked out your suggested command to obtain the HDMI port number, which worked like a charm!

Although the expected hdmi_input value should be a hardware identifier as defined in tv_input module.

On my Sony Bravia KD-55XD7005 were the following hardware definitions, mapped to input using the respective TV Input Manager service intent.

• HW2 (HDMI 1)

am start -a android.intent.action.VIEW -d content://android.media.tv/passthrough/com.sony.dtv.tvinput.external%2F.ExternalTvInputService%2FHW2 -n com.sony.dtv.tvx/.MainActivity -f 0x10000000

• HW3 (HDMI 2)

am start -a android.intent.action.VIEW -d content://android.media.tv/passthrough/com.sony.dtv.tvinput.external%2F.ExternalTvInputService%2FHW3 -n com.sony.dtv.tvx/.MainActivity -f 0x10000000

• HW4 (HDMI 3 / ARC)

am start -a android.intent.action.VIEW -d content://android.media.tv/passthrough/com.sony.dtv.tvinput.external%2F.ExternalTvInputService%2FHW4 -n com.sony.dtv.tvx/.MainActivity -f 0x10000000

• HW5 (HDMI 4)

am start -a android.intent.action.VIEW -d content://android.media.tv/passthrough/com.sony.dtv.tvinput.external%2F.ExternalTvInputService%2FHW5 -n com.sony.dtv.tvx/.MainActivity -f 0x10000000

• HW6 (AV1)

am start -a android.intent.action.VIEW -d content://android.media.tv/passthrough/com.sony.dtv.tvinput.external%2F.ExternalTvInputService%2FHW6 -n com.sony.dtv.tvx/.MainActivity -f 0x10000000

• HW7 (AV2)

am start -a android.intent.action.VIEW -d content://android.media.tv/passthrough/com.sony.dtv.tvinput.external%2F.ExternalTvInputService%2FHW7 -n com.sony.dtv.tvx/.MainActivity -f 0x10000000

In case you are interested, here is my proposed command, as in the linked pull request (66840c2), to obtain hardware identifier for both Sony TV (com.sony.dtv.tvinput.external) and other devices (com.mediatek.tvinput).

dumpsys activity starter | grep -E -o '(ExternalTv|HDMI)InputService/HW[0-9]' -m 1 | grep -o 'HW[0-9]'

@axxelh @JeffLIrion This has been addressed in v0.0.58 with the changes from #236.
