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.

Undefined

[−] Expand description

undefined format

Default

[−] Expand description

the default format of the pad/element. This can be samples for raw audio, frames/fields for raw video (some, but not all, elements support this; use Self::Time if you don’t have a good reason to query for samples/frames)

Bytes

[−] Expand description

bytes

Time

[−] Expand description

time in nanoseconds

Buffers

[−] Expand description

buffers (few, if any, elements implement this as of May 2009)

Percent

[−] Expand description

percentage of stream (few, if any, elements implement this as of May 2009)
