ffmpeg_presets	FFmpeg presets

import ConfigTabs from "@site/src/components/ConfigTabs"; import TabItem from "@theme/TabItem"; import NavPath from "@site/src/components/NavPath";

Some presets of FFmpeg args are provided by default to make the configuration easier. All presets can be seen in this file.

Hwaccel Presets

It is highly recommended to use hwaccel presets in the config. These presets not only replace the longer args, but they also give Frigate hints of what hardware is available and allows Frigate to make other optimizations using the GPU such as when encoding the birdseye restream or when scaling a stream that has a size different than the native stream size.

See the hwaccel docs for more info on how to setup hwaccel for your GPU / iGPU.

Preset	Usage	Other Notes
preset-rpi-64-h264	64 bit Rpi with h264 stream
preset-rpi-64-h265	64 bit Rpi with h265 stream
preset-vaapi	Intel & AMD VAAPI	Check hwaccel docs to ensure correct driver is chosen
preset-intel-qsv-h264	Intel QSV with h264 stream	If issues occur recommend using vaapi preset instead
preset-intel-qsv-h265	Intel QSV with h265 stream	If issues occur recommend using vaapi preset instead
preset-nvidia	Nvidia GPU
preset-jetson-h264	Nvidia Jetson with h264 stream
preset-jetson-h265	Nvidia Jetson with h265 stream
preset-rkmpp	Rockchip MPP	Use image with *-rk suffix and privileged mode

Select the appropriate hwaccel preset for your hardware.

1. Navigate to and set Hardware acceleration arguments to the appropriate preset for your hardware.
2. To override for a specific camera, navigate to and set Hardware acceleration arguments for that camera.

Input Args Presets

Input args presets help make the config more readable and handle use cases for different types of streams to ensure maximum compatibility.

See the camera specific docs for more info on non-standard cameras and recommendations for using them in Frigate.

Preset	Usage	Other Notes
preset-http-jpeg-generic	HTTP Live Jpeg	Recommend restreaming live jpeg instead
preset-http-mjpeg-generic	HTTP Mjpeg Stream	Recommend restreaming mjpeg stream instead
preset-http-reolink	Reolink HTTP-FLV Stream	Only for reolink http, not when restreaming as rtsp
preset-rtmp-generic	RTMP Stream
preset-rtsp-generic	RTSP Stream	This is the default when nothing is specified
preset-rtsp-restream	RTSP Stream from restream	Use for rtsp restream as source for frigate
preset-rtsp-restream-low-latency	RTSP Stream from restream	Use for rtsp restream as source for frigate to lower latency, may cause issues with some cameras
preset-rtsp-udp	RTSP Stream via UDP	Use when camera is UDP only
preset-rtsp-blue-iris	Blue Iris RTSP Stream	Use when consuming a stream from Blue Iris

:::warning

It is important to be mindful of input args when using restream because you can have a mix of protocols. http and rtmp presets cannot be used with rtsp streams. For example, when using a reolink cam with the rtsp restream as a source for record the preset-http-reolink will cause a crash. In this case presets will need to be set at the stream level. See the example below.

Output Args Presets

Output args presets help make the config more readable and handle use cases for different types of streams to ensure consistent recordings.

Preset	Usage	Other Notes
preset-record-generic	Record WITHOUT audio	If your camera doesn't have audio, or if you don't want to record audio, use this option
preset-record-generic-audio-copy	Record WITH original audio	Use this to enable audio in recordings
preset-record-generic-audio-aac	Record WITH transcoded aac audio	This is the default when no option is specified. Use it to transcode audio to AAC. If the source is already in AAC format, use preset-record-generic-audio-copy instead to avoid unnecessary re-encoding
preset-record-mjpeg	Record an mjpeg stream	Recommend restreaming mjpeg stream instead
preset-record-jpeg	Record live jpeg	Recommend restreaming live jpeg instead
preset-record-ubiquiti	Record ubiquiti stream with audio	Recordings with ubiquiti non-standard audio
