Hello,

Error is not referencing plugin code. Can you enable debug mode and push log when EPIPE exception occur?

Hi,
I experience this failure with beta.9 sometimes with Doorbell (T8210) and most of the times with a Floodlight Cam (T8424). It happens when starting a stream manually in home app. Screenshot fetch stream seams to work without issues.

This seems to be related to ffmpeg .. I will attach logs as soon as I enabled debug and can generate a little more output.

Hi,

this error seems to be some type of race condition in the code.
If a stream was started (for me it happened also with snapshots sometimes) the streams are piped into the ffmpeg process.
Eventually the stream is stopped and the ffmpeg process shuts down. However sometimes the eufy-security-client still sends a video package into the process. ffmpeg might already be exited but the input stream is still open. In the code you can see, that the input stream is closed just shortly after the process is exited.
If that happens the error occurs due to that the package cannot be written into the process.

I don't see what there could be done at the moment but also this error doesn't seem to have any effect apart of the log output.

This error should be fixed with 2.1.0-beta.14

Is fixed with release of 2.1.0
