The 091217b workaround of telling ffmpeg to only request the video
stream works perfectly fine for now. I'll revisit when adding audio
support (#34).

## Logs
|
|
|
|
While Moonfire NVR is running, logs will be written to stderr.
|
|
|
|
* When running `moonfire-nvr config`, you typically should redirect stderr
|
|
to a text file to avoid poor interaction between the interactive stdout
|
|
output and the logging.
|
|
* When running through systemd, stderr will be redirected to the journal.
|
|
Try `sudo journalctl --unit moonfire-nvr` to view the logs. You also
|
|
likely want to set `MOONFIRE_FORMAT=google-systemd` to format logs as
|
|
expected by systemd.
|
|
|
|
Logging options are controlled by environmental variables:
|
|
|
|
* `MOONFIRE_LOG` controls the log level. Its format is similar to the
|
|
`RUST_LOG` variable used by the
|
|
[env-logger](http://rust-lang-nursery.github.io/log/env_logger/) crate.
|
|
`MOONFIRE_LOG=info` is the default.
|
|
`MOONFIRE_LOG=info,moonfire_nvr=debug` gives more detailed logging of the
|
|
`moonfire_nvr` crate itself.
|
|
* `MOONFIRE_FORMAT` selects the output format. The two options currently
|
|
accepted are `google` (the default, like the Google
|
|
[glog](https://github.com/google/glog) package) and `google-systemd` (a
|
|
variation for better systemd compatibility).
|
|

|
## Problems
|
|
|
|
### `Error: pts not monotonically increasing; got 26615520 then 26539470`
|
|
|
|
If your streams cut out with an error message like this one, it might mean
|
|
that your camera outputs [B
|
|
frames](https://en.wikipedia.org/wiki/Video_compression_picture_types#Bi-directional_predicted_.28B.29_frames.2Fslices_.28macroblocks.29).
|
|
If you believe this is the case, file a feature request; Moonfire NVR
|
|
currently doesn't support B frames. You may be able to configure your camera
|
|
to disable B frames in the meantime.
|
|
|
|
### `moonfire-nvr config` displays garbage
|
|
|
|
This happens if your machine is configured to a non-UTF-8 locale, due to
|
|
gyscos/Cursive#13. As a workaround, type `export LC_ALL=en_US.UTF-8` prior to
|
|
running `moonfire-nvr config`.
|
|
|
|
### Logging in is very very slow
|
|
|
|
Ensure you're using a build compiled with the `--release` flag. See
|
|
[libpasta/libpasta#9](https://github.com/libpasta/libpasta/issues/9) for more
|
|
background.
