That sounds like a bug. > Why can't we just export both? for A53/SCTE20/DVDCC are exprted by A53_CC side data and they're sharing the same a53_buf_ref to store the data, so if stream contains CC wrapped as ATSC A53 packets + the same data wrapped as SCTE-20 packets, the CC data will repeated. We can consider to add a new side data type if necessary, but it's preferable to export A53_CC even it's SCTE20, so we can't export both by A53_CC still.
