Connect command parameters

Fields

app: String

Application name

flash_ver: Option<String>

Flash version

swf_url: Option<String>

SWF URL

tc_url: Option<String>

TC URL (full RTMP URL)

fpad: bool

Is FPAD

audio_codecs: u32

Audio codecs

video_codecs: u32

Video codecs

video_function: u32

Video function

page_url: Option<String>

Page URL

object_encoding: f64

Object encoding (AMF version)

extra: HashMap<String, AmfValue>

Extra properties from connect object

fourcc_list: Option<Vec<String>>

List of supported FOURCC codec strings (e.g., [“avc1”, “hvc1”, “av01”])

This is an alternative to the info maps; if present, all listed codecs are assumed to have full capability (decode + encode + forward).

video_fourcc_info_map: Option<HashMap<String, u32>>

Video codec capabilities by FOURCC string.

Maps FOURCC strings (e.g., “avc1”, “hvc1”) to capability bitmask:

• 0x01: Can decode
• 0x02: Can encode
• 0x04: Can forward/relay

audio_fourcc_info_map: Option<HashMap<String, u32>>

Audio codec capabilities by FOURCC string.

Maps FOURCC strings (e.g., “mp4a”, “Opus”) to capability bitmask.

caps_ex: Option<u32>

Extended capabilities bitmask (E-RTMP capsEx field).

• 0x01: Reconnect support
• 0x02: Multitrack support
• 0x04: ModEx signal parsing
• 0x08: Nanosecond timestamp offset

Implementations

impl ConnectParams

pub fn from_amf(obj: &AmfValue) -> Self

Parse from AMF command object

pub fn has_enhanced_rtmp(&self) -> bool

Check if this connect request includes E-RTMP capabilities.

Returns true if any E-RTMP fields are present (fourCcList, info maps, or capsEx).

pub fn caps_ex_flags(&self) -> CapsEx

Get the CapsEx flags if present.

pub fn to_enhanced_capabilities(&self) -> EnhancedCapabilities

Convert E-RTMP fields to EnhancedCapabilities for negotiation.

This extracts the client’s declared capabilities from the connect params.

Trait Implementations

impl Clone for ConnectParams

fn clone(&self) -> ConnectParams

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ConnectParams

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ConnectParams

fn default() -> ConnectParams

Returns the “default value” for a type.
