Yes, even that DVD and Blu-ray video discs are lesser usual than
previously, I agree we have to keep this features working in CinGG.
<br>
I guess it is the autoplay function that may not work, and that a
wrong aspect ratio video disc format possibly can be seen as data
discs(?)<br>
<br>
Phyllis, have you tried if possibly VLC's Media> Open Disc can
playback the DVD or BD video format?<br>
<br>
As I said, also at the icon level in Gnome File manager, it it
possible to see that the CinGG rendered webm files are visually
squeezed horizontally, compared with the correct format muxed with
FFmpeg 6.0:<br>
easy to see the difference between 4:3 sqeezed webm vs 16:9 wide
from (HDV) wide format.<br>
<br>
In VLC these files are loaded squeezed as default, but it can be
easily corrected with VLC's Videol > Aspect Ratio and select 4:3
for webm from SD DV sources and 16:9 for webm from HDV 1080i files.<br>
<br>
<br>
Not to repeat myself, but below is a condensed output from how
Mediainfo and FFprobe detect the aspect ratios of my tested SD and
HDV sources and webm files:<br>
