class LinearBufferManager

Defined at line 42 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.
