Birdseye RTSP restream can be enabled at `restream -> birdseye` and accessed at `rtsp://<frigate_host>:8554/birdseye`. Enabling the restream will cause birdseye to run 24/7 which may increase CPU usage somewhat.
#### Changing Restream Codec
#### Changing Restream Codec {#changing-restream-codec}
Generally it is recommended to let the codec from the camera be copied. But there may be some cases where h265 needs to be transcoded as h264 or an MJPEG stream can be encoded and restreamed as h264. In this case the encoding will need to be set, if any hardware acceleration presets are set then that will be used to encode the stream.

This error message is due to a shm-size that is too small. Try updating your shm-size according to [this guide](../frigate/installation.md#calculating-required-shm-size).
### I am seeing a solid green image for my camera.
A solid green image means that Frigate has not received any frames from ffmpeg. Check the logs to see why ffmpeg is exiting and adjust your ffmpeg args accordingly.
### How can I get sound or audio in my recordings? {#audio-in-recordings}
By default, Frigate removes audio from recordings to reduce the likelihood of failing for invalid data. If you would like to include audio, you need to override the output args to remove `-an` for where you want to include audio. The recommended audio codec is `aac`. The default ffmpeg args are shown [here](../configuration/index.md/#full-configuration-reference).
By default, Frigate removes audio from recordings to reduce the likelihood of failing for invalid data. If you would like to include audio, you need to set a [FFmpeg preset](/configuration/ffmpeg_presets) that supports audio:
:::tip
When using `-c:a aac`, do not forget to replace `-c copy` with `-c:v copy`. Example:
```diff title="frigate.yml"
```yaml title="frigate.yml"
ffmpeg:
output_args:
- record: -f segment -segment_time 10 -segment_format mp4 -reset_timestamps 1 -strftime 1 -c copy -an
+ record: -f segment -segment_time 10 -segment_format mp4 -reset_timestamps 1 -strftime 1 -c:v copy -c:a aac
record: preset-record-generic-audio
```
This is needed because the `-c` flag (without `:a` or `:v`) applies for both audio and video, thus making it conflicting with `-c:a aac`.

This almost always means that the width/height defined for your camera are not correct. Double check the resolution with vlc or another player. Also make sure you don't have the width and height values backwards.

Ensure your cameras send h264 encoded video
Ensure your cameras send h264 encoded video, or [transcode them](/configuration/restream.md#changing-restream-codec).
