[SOLVED] Panasonic_bluray Integration - SKIPREV, SKIPFWD, and OP_CL incorporated (CD PLAYER FUNCTIONALITY)

K-n-C · March 23, 2024, 3:27pm

I have been playing around with panacotta and realized there are a ton of commands that are not incorporated? I am just learning python, so I am not sure how to modify the if/else statements to make everything work, but it seems that the following could be added to the PanasonicDB class section:

        | MediaPlayerEntityFeature.SKIPFWD
        | MediaPlayerEntityFeature.SKIPPREV
        | MediaPlayerEntityFeature.OP_CL
    )

and the following at the end:

    def media_prev(self) -> None:
        """Send prev command."""
        self._device.send_key("SKIPPREV")

    def media_next(self) -> None:
        """Send next command."""
        self._device.send_key("SKIPFWD")

    def media_eject(self) -> None:
        """Send eject command."""
        self._device.send_key("OP_CL")

to add previous/next/eject functionality? Curious why it was not added?

I tried to find the media_python.py file by nosing around in SSH, but am not having any success. I assume it is in a container (I do not know docker, so I have no clue how that works.)?

I am very interested in playing around with this, but first and foremost I think it would be a benefit to the integration if the added functions were added? I know there are not many users using it, but I think it would be a quick addition for someone that knows python better than me?

Given the lack of a codeowner for panasonic_bluray you may be doing this yourself.

Also you may be better on the panacotta GitHub, this is the first thing to do.

I have panacotta working fine in a linux VM on my laptop… Most of the commands working. I can not find where the media_player.py module resides on my HA install. I found the file on github and understand maybe 85% of the code. When I have time I am going to stick it on the VM I installed panacotta in and see if I can figure the rest of it out, and then make the modifications I suggested.

I am not a programmer so github use is about as mysterious as python was before I spent a couple years learning data types and beginning to understand the builtin functions. but If I can figure out how to get this working I will see if I can figure out how to make a feature submission on github.

Making some progress… So I figured out how to get into the container and modify the media_player.py by dropping to a terminal and entering:

docker exec -it homeassistant bash

then I change to the panasonic_bluray directory, backup the file, and modify the file:

cd /usr/src/homeassistant/homessistant/components/panasonic_bluray/
cp media_player.py media_player.bu
vi media_player.py

I then changed the media_player.py code to the following:

        """Send next command."""
        self._device.send_key("SKIPFWD")

The NEXT_TRACK feature now works! PREVIOUS_TRACK works, but when you get past 1 second, you have to trigger it twice. I can not figure out how to get OP_CL (Eject) to work, even though the function syntax is identical, but the service does not appear in the UI. If I add the OP_CL function it will throw an error…

If I check configuration in developer tools after adding the OP_CL code it does not error immediately, but I believe it is because HA has imported the original media_player.py into memory and it is not seeing the edit…
However, after I reboot, and check configuration from developer tools I get the following error:


Configuration warnings
Platform error 'media_player' from integration 'panasonic_bluray' - Exception importing homeassistant.components.panasonic_bluray.media_player

I believe there is a module check somewhere that does not like my additions. I have not added any logic to call the additional functions defined, so I don’t really understand why it errors. I have very basic python experience, so I still do not understand how this module gets called, and I definitely have not inspected all the other imports or completely understand the media_players.py modules code. I hope to learn more as I nose around.

restoring the backed up media_player.py, and rebooting gets rid of the error, even with the other files in the directory:

cp media_player.py media_player.mine
cp media_player.bu media_player.py

I am learning a lot, but without a programmers background I am afraid I am just going to be reaching for straws?! I have looked at the panacotta repo, and it has been a year since any edits, and there is minimal info. If anyone has any pointers or links to articles that might help me learn faster, I would appreciate it.

I HAVE IT WORKING for what I need! I was wanting a way to use the CD Player (yes I know obsolete technology for some, but I have hundreds of CDs, and the quality is much better than MP3s, so I still enjoy listening to them.) In any case here are the steps I went thru. They maybe advanced for some. It was a learning experience for me, but just make sure you have a backup and enjoy the playtime!

First enable Remote Connections in your bluray Network Settings?

I have an older DMP-BDT220 (which is supported), but I was beating my head against the wall until I figured out i had to change the Remote setting. I hope that helps.

Get Panacotta on a linux machine https://pypi.org/project/panacotta/

pip install panacotta

This will allow you to test from a linux box running python3 to see what your bluray supports.

This is a python script (panacotta_test.py) I wrote to test the functionality of my player:
#NOTE: be sure to put your device IP ADDRESS in at line 4

#!/usr/bin/python3 
import panacotta

bluray = panacotta.PanasonicBD('192.168.0.14')   # Change to your Device IP Address

KEYS = """

       ['POWER', 'OP_CL',
        'PLAYBACK', 'PAUSE', 'STOP', 'SKIPFWD', 'SKIPREV', 'REV',
        'D0', 'D1', 'D2', 'D3', 'D4', 'D5', 'D6', 'D7', 'D8', 'D9', 'D12',
        'SHARP',  # '#'
        'CLEAR',  # '*' /  CANCEL
        'UP', 'DOWN', 'LEFT', 'RIGHT', 'SELECT', 'RETURN', 'EXIT',
        'MLTNAVI',          # HOME
        'DSPSEL',           # STATUS
        'TITLE', 'MENU', 'PUPMENU',
        'SHFWD1', 'SHFWD2', 'SHFWD3', 'SHFWD4', 'SHFWD5',
        'SHREV1', 'SHREV2', 'SHREV3', 'SHREV4', 'SHREV5',
        'JLEFT', 'JRIGHT',

        'NETFLIX', 'SKYPE', 'V_CAST', '3D', 'NETWORK', 'AUDIOSEL',
        'KEYS', 'CUE', 'CHROMA',
        'MNBACK', 'MNSKIP', '2NDARY', 'PICTMD', 'DETAIL', 'RESOLUTN',
        # Playback view?
        'OSDONOFF', 'P_IN_P',
        ]

        'Q' to quit!

"""
while True:
    print("Device is currently %s" % bluray.get_play_status()[0])
    print(f"Available KEYS = {KEYS}")
    inp = input("Enter KEY :").upper()
    if inp:
        inp = inp
        if inp == "Q":
             break
        else:
           print(f"executing bluray.send_key('{inp}')...")
           print(bluray.send_key(inp))

Once you confirm your panasonic device supports PLAYBACK, PAUSE, OP_CL, SKIPREV, and SKIPFWD…

If you have not done so already, you need to have the panasonic_bluray integration manually installed: https://www.home-assistant.io/integrations/panasonic_bluray

Then SSH or Terminal into your HA instance…

docker exec -it homeassistant bash

cd /usr/src/homeassistant/homessistant/components/panasonic_bluray/
cp media_player.py media_player.bu
vi media_player.py

change the media_player.py code to the following:
