Hello Stanimir,

On 2018-04-24 18:14, Stanimir Varbanov wrote:

This is implementing a multi-stream decoder support. The multi
stream gives an option to use the secondary decoder output
with different raw format (or the same in case of crop).

The dpb buffers queued to hardware will be returned back to host either during flush
or when the session is stopped. Host should not send these buffers to client.
vdec_buf_done should be handling in a way to drop dpb buffers from sending to client.
