The implementation in the Venus use HFI property for thumbnail generation to lower memory usage and when the control is enabled the number of decoder output buffers for progressive stream will be one (for interlace two). We assume that the client will queue on the decoder input intra frames only but this is not mandatory. If the client queue non-intra frames on decoder input they will be returned on decoder output with an error.
