That may be right, but I haven't done enough testing to know exactly and I wanted to be sure to catch all possible cases. With regards to the amount of "wasted" memory, there's a much more severe issue in vpp_qsv, because the alignment requirements for height and width are 16 pixels, not 32 pixels. This is done right in scale_qsv but not in vpp_qsv. I haven't changed that because I didn't want to mix two different issues in a single patch. > is this confirmed to be a bug from > https://github.com/Intel-Media-SDK/MediaSDK/issues ? I didn't bother to file a bug there, because I needed an immediate fix for all driver versions and can't wait for an update from that side. > without sample input video - patch has no meaning. I have forwarded the clip to you and to Zhong. When anybody else is interested, just drop me a note.
