Support proxy view for preview gifs

[NickM-27]

Might need some help with this, works on my live instance but for some reason it says that it doesn't work here

[kirsch33]

@NickM-27 i think its because for some reason the /review/<id>/preview.gif endpoint is missing the .gif part on the main Frigate repo:

https://github.com/blakeblackshear/frigate/blob/2e639415987ca3eb546aed842f06eef691636d8e/frigate/api/media.py#L1336

if i remove .gif from your code above it works

@kirsch33 the tests here have no knowledge of frigate code. Them failing is not directly related to it actually working in frigate or not

[kirsch33]

understood, regardless when I implemented this on my own it was not working without removing .gif so just wanted to mention it

[NickM-27]

yeah this PR is outdated since I implemented it

@dermotduffy can you take a look at this if you have a minute? I am at a loss as to why 500 is occurring when it works in actual usage

[dermotduffy]

@NickM-27 Had a shot. Note that I don't know what the real backend paths are, so you'll have to sanity check/edit my changes.

PS: You may kick yourself :-)

I see vs code wasn't warning me of my silly mistake. 😂

[dermotduffy]

@NickM-27 LGTM. I think we probably want this on dev?

Oops yep, updated
