Enum OutputContainer 

#[non_exhaustive]
pub enum OutputContainer {
    Mp4,
    FMp4,
    WebM,
    Mkv,
    Avi,
    Mov,
    Flac,
    Ogg,
}

Output container format for encoding.

The container format is usually auto-detected from the file extension, but can be explicitly specified if needed.

Named OutputContainer (rather than Container) to avoid confusion with ff_format::ContainerInfo, which describes a container read from a probed file.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Mp4

MP4 / QuickTime

FMp4

Fragmented MP4 — CMAF-compatible streaming container.

Uses the same mp4 FFmpeg muxer as OutputContainer::Mp4 but with movflags=+frag_keyframe+empty_moov+default_base_moof applied before writing the header. Required for HTTP Live Streaming fMP4 segments (CMAF) and MPEG-DASH.

WebM

WebM

Mkv

Matroska

Avi

AVI

Mov

MOV

Flac

FLAC (lossless audio container)

Ogg

OGG (audio container for Vorbis/Opus)

Implementations

impl OutputContainer

pub const fn as_str(self) -> &'static str

Get FFmpeg format name.

pub const fn default_extension(self) -> &'static str

Get default file extension.

pub const fn is_fragmented(self) -> bool

Returns true if this container is fragmented MP4.

When true, the encoder applies movflags=+frag_keyframe+empty_moov+default_base_moof before writing the file header, enabling CMAF-compatible streaming output.

Trait Implementations

impl Clone for OutputContainer

fn clone(&self) -> OutputContainer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OutputContainer

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

Formats the value using the given formatter.

impl PartialEq for OutputContainer

fn eq(&self, other: &OutputContainer) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
