Enum ConvertError

Source

#[non_exhaustive]pub enum ConvertError {
    NullFrame,
    UnsupportedPixelFormat(UnsupportedPixelFormat),
    InvalidPlaneLayout(InvalidPlaneLayout),
    BufferAcquireFailed(BufferAcquireFailed),
}

Expand description

Errors from av_frame_to_video_frame.

Variants (Non-exhaustive)§

This enum is marked as 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.

§

NullFrame

av_frame was null.

§

UnsupportedPixelFormat(UnsupportedPixelFormat)

The frame’s pixel format isn’t in the closed CPU-format set this crate supports for safe per-plane access.

§

InvalidPlaneLayout(InvalidPlaneLayout)

A plane reported linesize <= 0 or otherwise inconsistent layout.

§

BufferAcquireFailed(BufferAcquireFailed)

Failed to acquire an AVBufferRef for a plane (out of memory, or the frame’s data[i] pointer doesn’t lie inside any of buf[]).
