Correct, that's what I meant to say.
The sample in question is https://streams.videolan.org/issues/19938/20000_20180305-15.04.59.ts
Which is coded as 1920x1080, meant to be rendered at 1440x1080 with cropping,
or 1680x1080 before cropping. Currently, the created DPB is 1440x1080, which results
in the image being decoded incorrectly, as the decoder overwrites output memory.
This commit fixes this.
Added this to the commit description locally.
