So, I tried to clarify a bit that we have display aspect ratio
selectable, updated cingg team copyright year, added even more
finegrained sar/dar reporting (guessed, container detected, codec
detected).
I tried to use libavutil function for reporting SAR in setformat.C
but it need some dynamic gui subwindow/object, not static
BCTitle... so just prototype that does not update as you update
window, only calculated on window objects create time, so each
time you reopen set format window.
3 new git diff patches hopefully for application
0003 should be applied on top of
0001-Add-guessed-detected-SAR-DAR-values-to-ffmpeg-asset-.patch
from another thread
one plain diff patch just for showing where SAR info might surface
if I ever learn now to create dynamic text subwindows :)
oh, I calculated SAR wrongly in setformat patch, so this one should
obviously only considered as placeholder/mockup.
Still not sure to what exactly w/h ratio fields in setformat window
relate - I thought about preset vs canvas size but this does not hold
up in testing ...
According to the Cin-CV manual:
http://cinelerra-cv.wikidot.com/cincv-manual-en:project-attributes#toc4
*W Ratio, H Ratio*
Sets the ratio of the new canvas size (W, H) to the old (previous)
canvas size (W, H). The new canvas size is recalculated based upon a
certain factor in the W Ratio, H Ratio fields. A practical use-case:
The current resolution is 640x480, and for some reason you want it
to be 1.33 times wider. You don't have to calculate what 640x1.33
is; you type 1.33 into the "W" input instead, and Cinelerra
calculates it for you. This tutorial
<https://linuxvideoediting.blogspot.com/2023/08/canvas-w-ratio-h-ratio-cinelerra.html>
explores in more detail these settings. It is in Russian but easily
translatable with GoogleTranslator, DeepL or similar.
The latter Tutorial can be translated ......
