I using the emby server in docker env. in my region (CN) access other network is diffuclt somes like the Cloudflare Workers ,my strm file resource is pass the CF network.In that, i have to use the proxy.

for the network setting , set the proxy.

- 'HTTP_PROXY=http://127.0.0.1:7890'
- 'HTTPS_PROXY=http://127.0.0.1:7890'

the ffprobe don't use the env variable，must add the argc like  -http_proxy http://127.0.0.1:7890

i test in my windows terminal add the argc the cmd work good.So i wanna help devoloper can take some if addition, if env.http_proxy : cmd take the -http_proxy http://127.0.0.1:7890 additionally.

If that's the case, I'd be incredibly grateful.
