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)

[+] 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.

Failed

[−] Expand description

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

TooLazy

[−] Expand description

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

NotImplemented

[−] Expand description

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

TypeNotFound

[−] Expand description

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

WrongType

[−] Expand description

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

CodecNotFound

[−] Expand description

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

Decode

[−] Expand description

used when decoding fails.

Encode

[−] Expand description

used when encoding fails.

Demux

[−] Expand description

used when demuxing fails.

Mux

[−] Expand description

used when muxing fails.

Format

[−] Expand description

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

Decrypt

[−] Expand description

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

DecryptNokey

[−] Expand description

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

NumErrors

[−] Expand description

the number of stream error types.
