Camera Stream not Loading in HA

[ScottRoach]

Describe the bug Camera stream does not load. Instead it returns either a 504 Timeout error from the homeassistant proxy url or an empty text response.

To Reproduce

1. Install the reolink_dev integration in hacs and reboot
2. Add a camera using main and rtsp (or rtmp)
3. Add a Picture card to dashboard
4. Clicking on the detail produces a broken image

Expected behavior When viewing the stream version of the camera (as compared to the screen grab) it should show what the camera sees instead of a broken image.

Screenshots

Environment: Please provide useful information about your environment, like:

• Home Assistant version: 2021.1.4 (docker)
• Reolink camera model: RLC-520A
• Camera firmware number: v3.0.0.116_20102900
• relink_dev component version: v0.13

Additional context I've tried the following things to troubleshoot:

• Set the reolink_dev integration logging to DEBUG - have not seen any errors - logs are below
• I verified with netstat that the HA host is making a successful connection to the camera when the stream is being requested homeassistant correct.camera.ipaddress.here:554 ESTABLISHED 15066/python3 Once the request times out the connection is no longer ESTABLISHED
• I verified on my local machine that the stream_url appears to be correctly formatted as rtsp://username:password@correct.camera.ipaddress.here:554/h264Preview_01_main
• If I manually add a generic camera with the stream_source from above it works as expected
• I verified that I can load the stream from inside the home assistant docker instance via ffmpeg without any network issues
• I have ffmpeg loaded in my config
• Tried switching between protocols and main and sub streams

Core Issue I've narrowed the issue down to this recent change: https://github.com/fwestenberg/reolink_dev/commit/a8cecc255131607fa741b02781b8ce814619cc38#diff-5a5bfae2f3cd9b046addab6f73b4563d28118ab7ff0d899c52de60f5d2556c3aL128-L140 (camera.py L128-140) If I revert that bit of code then the stream works correctly. It seems that when async_aiohttp_proxy_web is used instead of async_aiohttp_proxy_stream the request times out.

I get the same screenshot when I click on the picture card.
