Implementations§

Source§

impl VideoCapsBuilder<NoFeature>

Source

pub fn new() -> Self

Constructs an VideoCapsBuilder for the “video/x-raw” encoding.

If left unchanged, the resulting Caps will be initialized with:

  • “video/x-raw” encoding.
  • all available formats.
  • maximum width range.
  • maximum height range.

Use VideoCapsBuilder::for_encoding to specify another encoding.

Source

pub fn for_encoding(encoding: impl IntoGStr) -> Self

Constructs an VideoCapsBuilder for the specified encoding.

The resulting Caps will use the encoding argument as name and will not contain any additional fields unless explicitly added.

Source

pub fn for_encoding_from_static(encoding: impl AsRef<GStr> + 'static) -> Self

Constructs an VideoCapsBuilder for the specified encoding.

The resulting Caps will use the encoding argument as name and will not contain any additional fields unless explicitly added.

Source

pub fn for_encoding_from_id(encoding: impl AsRef<IdStr>) -> Self

Constructs an VideoCapsBuilder for the specified encoding.

The resulting Caps will use the encoding argument as name and will not contain any additional fields unless explicitly added.
