Blink.save_video files saved with 0 bytes

Configuration
1

Hi,

I have an automation to save blink videos which is working, but files saved are always 0 bytes.

For example, /media/20210208_151702_blink_video.mp4 with 0 bytes

The recorded video seems fine, and is viewable using the Blink app with a timestamp of 15:14 and is 8 seconds long.

There are no errors in the log files – just the following info entries related to the event:

Yeah this has been fixed in an update to the library that has not been rolled into home-assistant yet. If you’re python saavy enough you can edit the manifest.json in the components/blink folder to update blinkpy to either 0.16.5rc0 or 17.0.0rc0. note, you’d also have to make this change in the requirements.txt file (just grep for blinkpy to find all the places to update…that’s probably easiest)

If what I just said sounded like nonsense, don’t worry, just hold tight and I’ll try to get the fix into HA soon :slight_smile:

I added an issue to home-assistant to track. So you can follow here to see progress :+1: https://github.com/home-assistant/core/issues/46447#issuecomment-778163631

Thanks @fronzbot. Will give it a try.
