Enum cros_codecs::utils::vaapi::StreamMetadataState

pub(crate) enum StreamMetadataState {
    Unparsed {
        display: Rc<Display>,
    },
    Parsed(ParsedStreamMetadata),
}

State of the input stream, which can be either unparsed (we don’t know the stream properties yet) or parsed (we know the stream properties and are ready to decode).

Variants

Unparsed

Fields

display: Rc<Display>

The metadata for the current stream has not yet been parsed.

Parsed(ParsedStreamMetadata)

The metadata for the current stream has been parsed and a suitable VAContext has been created to accomodate it.

Implementations

impl StreamMetadataState

pub(crate) fn display(&self) -> Rc<Display>

pub(crate) fn get_parsed(&self) -> Result<&ParsedStreamMetadata>

Returns a reference to the parsed metadata state or an error if we haven’t reached that state yet.

pub(crate) fn get_parsed_mut(&mut self) -> Result<&mut ParsedStreamMetadata>

Returns a mutable reference to the parsed metadata state or an error if we haven’t reached that state yet.

pub(crate) fn supported_formats_for_stream(
    &self
) -> Result<HashSet<DecodedFormat>>

Gets a set of supported formats for the particular stream being processed. This requires that some buffers be processed before this call is made. Only formats that are compatible with the current color space, bit depth, and chroma format are returned such that no conversion is needed.

pub(crate) fn open<S: StreamInfo>(
    &mut self,
    hdr: S,
    format_map: Option<&FormatMap>
) -> Result<()>

Initializes or reinitializes the codec state.
