-------------------------------------+-------------------------------------
When trying to extract a frame from a video, the video orientation
metadata is taken into account, but the output dimensions are wrong.
Notice in the example the height and width are swapped, resulting in a
warped output.
I am using ImageMagick to convert the concatenated PNG files to a single
JPEG, but the concat'd PNG still exhibits the issue.
Repro:
ffmpeg -t 1.0 -i file.webm -frames:v 120 -codec:v png -compression_level 0
-f image2pipe out.png
