Clients needing codec information prior to just requesting a codec with
CodecFactory.CreateDecoder or CodecFactory.CreateEncoder should use GetDetailedCodecDescriptions
to get this table, which has details re. the codec and the profile entries supported by the
codec.
Clients with no real need for codec information prior to requesting a codec can simply use
CodecFactory.CreateDecoder or CodecFactory.CreateEncoder with relevant requirements set in that
request, and then call StreamProcessor.Sync (round trip) to see if a codec was created
successfully.

const uint32_t & dynamic_buffers_video_decoder_output_safe ()This field is set when a codec both supports dynamic buffers and is a
video decoder. Adding this many buffers to a video decoder's output, and
ensuring that the buffers will be usable by the decoder prior to the
whole pipeline blocking on lack of availability of usable output buffers
in the decoder, will ensure that the decoder doesn't get stuck waiting
for an available output buffer. See also
`[fuchsia.mediacodec/StreamBufferConstraints.buffer_count_for_server_current]`
which may occasionally indicate a lower number of output buffers needed,
based on headers of the bitstream. However, implementers of clients may
wish to first check if the relevant headers in relevant streams are
actually set, since this can be rare in practice unfortunately, making
paying attention to buffer_count_for_server_current potentially not
actually worthwhile, depending on the expected streams' headers.

string to require an instance of this specific codec. The created codec
will still be checked against other requirements specified there for the

This is only valid and specific per boot, not across boots. This allows
a discovered codec to be requested without any ambiguity, but is
intentionally not a way for clients to hard code which specific codec
implementation they want to connect to, as codec selection is by
properties / capabilities, not by specific codec implementation.
