class TiledBufferManager

Defined at line 462 of file ../../src/media/codec/codecs/vaapi/codec_adapter_vaapi_decoder.cc

This class manages output buffers when the client selects a tiled buffer output. Since the output

is tiled the client will directly share the output from the decoded picture buffer (DPB). The

manager will be responsible for creating the DPB surfaces that are backed by CodecBuffers the

client provides us. The manager is also responsible for reconfiguring surfaces when a mid stream

configuration change is required.

scoped_refptr<VASurface> GetDPBSurface ()

Getting a DPB requires that the surface is not in use by the client. This differs from the

linear version where DPB were not backed by a VMO. This function will block until a buffer is

recycled by the client or the manager is reset by the codec.
