[Bug]: Video stream freezes 1-2sec for a brief second after start of every HKSV recording
### What happened?

Dual Wired Doorbell:
Every video recording made by HKSV has a momentary freeze for about 1-2 seconds right at the beginning. The recording usually plays fine (sometime a little choppy) after the initial freeze, but I end up missing the important action that happened during those few secs. Sometimes I only get the first few seconds of the event and the recording just terminates in the middle of the event. Homekit is not liking the current stream apparently. I have tried changing various plugin settings: the snapshot options, changing the snapshot refresh interval, changing a few setting in the advanced ffmpeg encoding section (render audio and video together). Tried changing settings in the Eufy app: streaming quality, video encoding format (high doesn't work at all with plugin/homekit), notification content types. Eufy combine 2 cameras into 1 video stream that looks like a 4:3 split view size format or a more tradition 16:4 type video size with a picture in picture. I've tried both formats and it still freezes. Nothing seems to fix this issue.

I have a strong wifi network and an Asus wifi 6 router that  is about 10-20 ft away. I'm currently just copying the stream since homekit accepts the doorbell stream as-is and it's fast to load up. Maybe I need to render ffmpeg with specific settings, but I don't know where to start. I have debug logs with the ffmpeg debug on.
