Enum SubtitleDecodeError 

pub enum SubtitleDecodeError {
    Decode(Error),
    Convert(ConvertError),
    NoFrameReady,
    FramePending,
}

Errors from FfmpegSubtitleStreamDecoder.

Variants

Decode(Error)

The wrapped ffmpeg::decoder::Subtitle reported an error.

Convert(ConvertError)

Conversion from FFmpeg’s AVSubtitle to mediadecode’s SubtitleFrame failed.

NoFrameReady

receive_frame was called with no buffered frame ready — caller should send another packet.

FramePending

send_packet was called while a decoded frame from a previous packet hasn’t been drained — the legacy decode() API can’t queue, so the caller must drain via receive_frame first.
