Struct AVDiscard

#[repr(transparent)]
pub struct AVDiscard(pub i32);

Discard levels used in FFmpeg’s AVDiscard.

These values specify how much of the input stream should be discarded.

See the official FFmpeg documentation: https://ffmpeg.org/doxygen/trunk/avcodec_8h.html

Implementations

impl AVDiscard

pub const None: Self

Discard nothing (decode everything).

• Used for: Keeping all packets.
• Binary representation: -0b10000
• Equivalent to: AVDISCARD_NONE

pub const Default: Self

Discard useless packets (e.g., zero-size packets in AVI).

• Used for: Cleaning up unnecessary data.
• Binary representation: 0b00000
• Equivalent to: AVDISCARD_DEFAULT

pub const NonRef: Self

Discard all non-reference frames.

• Used for: Reducing decoding load while keeping keyframe accuracy.
• Binary representation: 0b01000
• Equivalent to: AVDISCARD_NONREF

pub const Bidir: Self

Discard all bidirectional (B) frames.

• Used for: Lower latency decoding, reducing memory usage.
• Binary representation: 0b10000
• Equivalent to: AVDISCARD_BIDIR

pub const NonIntra: Self

Discard all non-intra frames.

• Used for: Keeping only intra-coded frames (I-frames).
• Binary representation: 0b11000
• Equivalent to: AVDISCARD_NONINTRA

pub const NonKey: Self

Discard all frames except keyframes.

• Used for: Extracting only keyframes from a stream.
• Binary representation: 0b100000
• Equivalent to: AVDISCARD_NONKEY

pub const All: Self

Discard all frames (decode nothing).

• Used for: Disabling decoding entirely.
• Binary representation: 0b110000
• Equivalent to: AVDISCARD_ALL
