class LinearBufferManager
Defined at line 41 of file ../../src/media/codec/codecs/vaapi/codec_adapter_vaapi_decoder.cc
This class manages output buffers when the client selects a linear buffer output. Since the
output is linear the client will have to deswizzle the output from the decoded picture buffer
(DPB) meaning that we can't directly share the output with the client. The manager will be
responsible for creating the DPB surfaces used by the decoder and reconstructing them when a mid
stream configuration change is required. This buffer manager will also be responsible for copying
the output from the DBPs to the CodecBuffers the client provides us.
