Struct AVSeekWhence

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

Seek flags used in FFmpeg’s av_seek_frame function.

These flags modify how seeking is performed in media files.

See the official FFmpeg documentation: https://ffmpeg.org/doxygen/trunk/group__lavf__decoding.html#gaa59bdaec0590cc36300753c5cf6c9d49

Implementations

impl AVSeekWhence

pub const Start: Self

Seek from the beginning of the file.

• Used for: Seeking from the start of the file.
• Binary representation: 0b0000000000000001
• Equivalent to: SEEK_SET

pub const Current: Self

Seek from the current position.

• Used for: Seeking from the current position.
• Binary representation: 0b0000000000000010
• Equivalent to: SEEK_CUR

pub const End: Self

Seek from the end of the file.

• Used for: Seeking from the end of the file.
• Binary representation: 0b0000000000000100
• Equivalent to: SEEK_END

pub const Size: Self

Return the file size instead of performing a seek.

• Used for: Querying the total file size.
• Binary representation: 0b00000000000000010000000000000000
• Equivalent to: AVSEEK_SIZE

pub const Force: Self

Force seeking, even if the demuxer does not indicate it supports it.

• Used for: Forcing a seek operation when the demuxer might otherwise refuse.
• Binary representation: 0b00000000000000100000000000000000
• Equivalent to: AVSEEK_FORCE
