isa.camera.hlc6 crashes on hw_ver

[marines]

I've just set up a fresh HA instance and I'm trying to integrate the isa.camera.hlc6 camera. I'm running HA in a docker container in host network mode. I've tried the latest stable, latest beta and master branch build of the integration. I'm using Europe Mi servers.

Providing host/token ends up with the following error on initialization:

Setting up an integration with Mi Account credentials successfuly adds devices but it shows either that camera is off or there was an error opening stream:

homeassistant    | 2021-03-14 17:09:56 ERROR (MainThread) [homeassistant.components.camera] Error requesting stream: Camera is off

homeassistant    | 2021-03-14 17:13:25 ERROR (stream_worker) [homeassistant.components.stream.worker] Error opening stream https://de01.livestreaming.io.mi.com/hlstranscoder/.../playlist.m3u8

Let me know if I can help fixing this somehow as I cannot use the camera in HA. :(

Just to add that with the above fix the camera can be added properly but it says that camera is off when trying to view the feed.

[al-one]

Get the stream_address from the entity state attributes (Developer tools > State), and test whether it can play through VLC and other players.

[marines]

There is no stream_address attribute. :/

[al-one]

Before getting the stream address, click on the camera entity dialog, and the stream address is only valid for 5 minutes.

[marines]

I have also tried that before but stream_address didn't show up.

[al-one]

The state_updater is lan, do your enable miot_cloud ?

[marines]

Right. Forgot that the camera requires cloud connection. So with cloud connection enabled there is the issue I've described in the first post.

Here's the entity state:

The playlist file is accessible by both my PC and HA container and has the following content (except X-es):

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-STREAM-INF:BANDWIDTH=250000
chunklist_w2XXXXXXX1.m3u8

But VLC just spins trying to load the stream.

[lexin8]

Abnormal camera access seems not a case. At present, the plug-in is not well supported!

[marines]

@al-one Does that mean it can't be fixed?

[al-one]

If the stream address is not available, then I have no idea.
This component only get stream address from xiaomi cloud and generates camera entity proxy to stream address through HA ffmpeg.
