[vlc-devel] [PATCH] demux: mock: Add orientation option

[Tanguy Dubroca]

Usage: ./vlc 'mock://<mock options>;video_orientation=<orientation>'

The video_orientation option is a simplification of the values from
video_orientation_t. The possible values are:

- normal
- transposed / antitransposed
- hflipped / vflipped
- rotated_90 / rotated_180 / rotated_270

Fix #25054
