Re: [PATCH 0/2] MR9538: winegstreamer: Return S_FALSE from DMO when there is not enough data.

[Yuxuan Shui (＠yshui)]

Context: I was trying to make use of DMOs in `WMSyncReader`. I want to know if there is data available from a DMO decoder. Maybe there's a better way, but intuitively I call `ProcessOutput` and check if it returns `S_FALSE`.

Our DMOs return `MF_E_TRANSFORM_NEED_MORE_INPUT` which is not a documented return value for DMOs.
