show vacuum's map as camera

[licheng5625]

Hello,
inspired by and partially copied from project , I would like to show vacuums' map on HASS as a camera.

I have a few problems, I need support from experts.

1. The state of the camera is always unavailbe, even though I can fetch the snapshot
   

2. I cannot open the camera view
   
   error is :
   2022-01-10 05:13:24 WARNING (MainThread) [homeassistant.components.http.ban] Login attempt or request with invalid authentication from 172.17.0.1 (172.17.0.1). (Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.110 Safari/537.36)
   But I can open the link /api/camera_proxy/camera.rockrobo_v1_7d69_vacuum_map?token=55409880 with browser without issue.

3. When I implement the camera entity, HA was complaining about entity_picture and access_token are missing. But I checked the orignal project or the simplest camera project. None of them set those attributs. I set them mannuly , it could cause the issue 2.

4. I hava a rockbot vacuum. I am not able to test ViomiVacuum

Thanks for your PR !
xiaomi_cloud_map_extractor is an excellent custom component, and it is always updated. I also use it. Maintaining this code takes a lot of time, and I don't think we should build wheels again.

I took the parse image part. If they could make it as a reuse library, it could be great.

My motivation is to reduce the number of login to xiaomi server. My experience is it causes unstable and make the app on the phone very laggy. If ask me to choose one central place to integrate things about xiaomi, i choose here.

Maybe you can try:

try:
    from custom_components.xiaomi_cloud_map_extractor.xiaomi.map_data_parser import MapDataParserXiaomi
except (ModuleNotFoundError, ImportError):
    MapDataParserXiaomi = None

The camera entity works only when the user installs xiaomi_cloud_map_extractor.

As the auther mentioned here, he might create a new repo to for parsing the image.

But if you have any time, could you help me with the issue 1 and 2 ?

thank you

access_tokens is recommended to be managed by HA core.

3 When I implement the camera entity, HA was complaining about entity_picture and access_token are missing. If I do not offer the token. HA will give an error about access token is missing.

entity_picture should also be managed by HA core.
And your need init the base Camera: Camera.__init__(self) before this line.

Thanks a lot for your hints. Camera does not work with Basesubentity. I have no idea why.

Test with Rockbot v1 works. Now you could decide wether to merge or not.
If not, just close this PR.

The Map for ijai.vacuum.v* vacuums are not yet supported by Xiaomi cloud map extractor. LINK

Does the map_data_parser in this PR support those?

Just curious. Thanks.
