Enum ImageDecodeError 

pub enum ImageDecodeError {
    InputTooLarge(InputTooLarge),
    Decode(Error),
    Convert(ConvertError),
    EmptyPayload,
    NoImage,
    Corrupt(Corrupt),
    TrustedPayload(TrustedPayload),
}

Errors from [FfmpegImageDecoder].

Variants

InputTooLarge(InputTooLarge)

The compressed payload is larger than the ceiling allows. Refused before it is copied into an AVPacket.

Decode(Error)

The wrapped ffmpeg::decoder::Video reported an error, or the codec context could not be built.

Convert(ConvertError)

Conversion from FFmpeg’s AVFrame to mediadecode’s ImageFrame failed — an undeliverable pixel format, or a plane layout the safe accessors refuse.

EmptyPayload

The attachment carried no bytes, so there is nothing to decode.

Distinct from Self::NoImage: this is an empty payload, which the demuxer synthesizes for an attachment track whose picture the container never stored.

NoImage

The payload was accepted and produced no picture — it is not an image this codec reads.

Corrupt(Corrupt)

Something on this road is marked corrupt, and an ImageFrame has nowhere to say so.

TrustedPayload(TrustedPayload)

The attachment is marked AV_PKT_FLAG_TRUSTED, so its body may hold pointers rather than bytes. See crate::buffer::TrustedPayload.
