Types

type Codec

type Codec struct {
	Id       string
	Name     string
	Encoders []string
	Decoders []string
}

Codec represents a codec with its availabe encoders and decoders

type Device

type Device struct {
	Id      string
	Name    string
	Devices []HWDevice
}

Device represents a type of device (e.g. V4L2) including connected actual devices

type Filter

type Filter struct {
	Id   string
	Name string
}

Filter represents a supported filter (e.g. anullsrc, test2)

type Format

type Format struct {
	Id   string
	Name string
}

Format represents a supported format (e.g. flv)

type HWAccel

	Id   string
	Name string
}

type HWDevice

type HWDevice struct {
	Id    string
	Name  string
	Extra string
	Media string
}

HWDevice represents a hardware device (e.g. USB device)

func DevicesALSA

func DevicesALSA() ([]HWDevice, error)

DevicesALSA returns a list of available ALSA devices

func DevicesAvfoundation

func DevicesAvfoundation(binary string) ([]HWDevice, error)

DevicesAvfoundation returns a list of AVFoundation devices. You have to provide the path to the ffmpeg binary.

func DevicesFramebuffer

func DevicesFramebuffer() ([]HWDevice, error)

DevicesFramebuffer returns a list of framebuffer devices found on the system

func DevicesV4L

func DevicesV4L() ([]HWDevice, error)

DevicesV4L returns a list of available V4L devices

type Library

type Library struct {
	Name     string
	Compiled string
	Linked   string
}

Library represents a linked av library

type Protocol

type Protocol struct {
	Id   string
	Name string
}

Protocol represents a supported protocol (e.g. rtsp)

type Skills

type Skills struct {
	FFmpeg ffmpeg

	Filters  []Filter
	HWAccels []HWAccel

	Codecs    ffCodecs
	Devices   ffDevices
	Formats   ffFormats
