Please make the return type of this function a boolean or an integer type that is decoupled from the VB2 buffer state. Thanks! Ezequiel > }; > > struct rkvdec_coded_fmt_desc { > -- > 2.38.1 >

This optional internal ops allow each codec to do their own error status checking. The presence of an error is reported using the ERROR buffer state. This patch have no functional changes.
