The DisplayUnit=4 (unknown) seems to be set at https://github.com/FFmpeg/FFmpeg/blob/1ec2b3de5a074ccce555e33d7f282bbbb6d963d7/libavformat/matroskaenc.c#L1292 sample_aspect_ratio.num and sample_aspect_ratio.den should be set to 1.

Sounds interesting, I suppose we'd need an adjustment to both the graph view and the player view: to show graphs over time based on too averaged videos and similar for...

Hi @pjotrek-b, when scaling I used the [neighbor](https://github.com/bavc/qctools/blob/fd15b6b73ba56e042f2c1d60e033c9728d3ba456/Source/GUI/player.cpp#L698-L705) scalar as I thought this would be the most authentic, however the downside is that a grid can be introduced depending on...

Hi @ElderOrb I was reviewing this and realized that mouse-wheel zooming no longer works on the graphs. The prior behavior was that a mouse-wheel move would zoom in or out...

Hi @briandwagner, thanks for pointing this out. Earlier in qctools it would mimic the xml output of ffprobe, so it was feasible to make roughly the same xml from either...

This involves many pieces and perhaps I'm missing a few. - update vectorscope in ffmpeg - adjust the levels used in the saturation graphs - ensure proper color reporting in...

Reopening and as a developer of this project disagree about the lack of interest.

Yes

Yes, there's obvious disadvantages, but the content could be de-interlacement to fields, scaled, then reinterlaced, but if it's progressive or undetermined we could scale as usual. I'm mostly thinking of...
