Hardware decode not working from HDHomerun

I'm using docker and it works for most streams, but sometimes I get these errors:

This obviously doesn't fix the transcoder issue, but have you thought about just running with original quality so that the stream is unmodified?

[eric]

Checking this out. Please submit diagnostics from the DVR if you have a chance.

[ehosch]

Logs have been submitted as 8dc64f71-5751-4110-9a21-bd24844e7692 .

[eric]

Thanks for the diagnostics. Checking it out.

[eric]

@ehosch could you update to the latest DVR pre-release and see if it's any better?

@tmm1

Updating to prerelease

On the DVR web UI, select Status > Version > Check For Update > Check for Pre-Release

Prerelease upgrades happen manually, only when you click the button above. The next time a stable release happens, your DVR will switch back to the newer stable build automatically.

[ehosch]

That worked! Do I have to do that every time my docker container restarts?

@ehosch

That worked! Do I have to do that every time my docker container restarts?

NO The container is automatically updated when you update to pre-release.
