Stream errors are for anything related to the stream being processed: format errors, media type errors, … They’re typically used by decoders, demuxers, converters, …

Variants (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.

Failed

a general error which doesn’t fit in any other category. Make sure you add a custom message to the error call.

TooLazy

do not use this except as a placeholder for deciding where to go while developing code.

NotImplemented

use this when you do not want to implement this functionality yet.

TypeNotFound

used when the element doesn’t know the stream’s type.

WrongType

used when the element doesn’t handle this type of stream.

CodecNotFound

used when there’s no codec to handle the stream’s type.

Decode

used when decoding fails.

Encode

used when encoding fails.

Demux

used when demuxing fails.

Mux

used when muxing fails.

Format

used when the stream is of the wrong format (for example, wrong caps).

Decrypt

used when the stream is encrypted and can’t be decrypted because this is not supported by the element.

DecryptNokey

used when the stream is encrypted and can’t be decrypted because no suitable key is available.

NumErrors

the number of stream error types.
