Hello,
I built a security system with a few Reolink Cameras (4MP/8MP). I use Synology Surveillance Station as my NVR. I’ve discovered a noticeable gap in stream quality but only when Chromecast is in the mix.
I can view the Synology camera streams in Home Assistant and they appear to be excellent quality.
I can do this from Reolink too but the Reolink integration doesn’t handle the 8MP well so for the purpose of this, we’re discussing just the synology feed.
Viewing video from my phone/desktop via HA works beautifully.
I have some snapshot mechanisms that take gorgeous pics and sends them to me.
When I tell HA to stream this same synology feed to a TV via Chromecast, I get potato quality.
Chromecast is hardwired to internet. TV is playing on is hardwired to internet. POE cams are all on the same network.
Here’s my system:
"installation_type": "Home Assistant OS",
"version": "2022.10.4",
"dev": false,
"hassio": true,
"virtualenv": false,
"python_version": "3.10.5",
"docker": true,
"arch": "x86_64",
"os_name": "Linux",
"os_version": "5.15.72",
"supervisor": "2022.10.0",
"host_os": "Home Assistant OS 9.2",
"docker_version": "20.10.17",
"chassis": "vm",
I have 10 GB RAM allocated and don’t use nearly that amount on a normal day:
I have a few questions:
Is this just the nature of chromecasting? is my expectation of 4k from an 8mp camera unrealistic?
Is this because the tv is so large and the stretch is what’s causing it? Recording resolution is 3840*2160
Is there a better way I should be streaming this? Another device I can purchase?
Admittedly, this is the most I’ve ever used a chromecast and I don’t know if there’s other settings that are preventing me from having the experience I’m expecting.
Because I get such consistently excellent quality from the Reolink, Synology, and Home Assistant feeds, I’m left with no choice but to think Chromecast is the part of this that has the problem.
Oh, and I’ve been told that the chromecasts I have are the upgraded ones whatever that means. I think they’re meant for 4k because they were from a Stadia installation.
Can somebody help me figure out why my 8mp Chromecast stream is such poor quality?
