What is Buffer Dimensions?

[Alessandro80]

Hello,
in VLC 2.2.x, decoding a 1920*1080 stream I found the "resolution" (under the codec tab) showing 10 lines more, : 1920*1090.
On the 3.x version this has been changed to "Buffer dimensions".

What exactly this parameter means? Is there any specific reason why there are 10 lines more?

Thanks in advance!

It is exactly what it says, the dimensions of the picture buffer(s).

Thanks for your answer, is there a reason why the buffer has always 10/25 lines more than the display resolution?
Thanks

It has to be as big as the display. How much depends.

Reason might be conveniance, or alignment. It mainly depends on the encoder/decoder and the file itself.
