This adds an option for higher frame rates from a simulated webcam.
Currently, vivid emulates (amongst other things) a webcam with somewhat
limited bandwidth - higher resolutions deliver fewer frames per second.
$ yavta --enum-formats -c /dev/video0
Device /dev/video0 opened.
Device `vivid' on `platform:vivid-000' (driver 'vivid') supports video, capture, without mplanes.
- Available formats:
Format 0: YUYV (56595559)
Type: Video capture (1)
Name: YUYV 4:2:2
Frame size: 320x180 (1/1, 1/2, 1/4, 1/5, 1/10, 2/25, 1/15, 1/25, 1/30, 1/40, 1/50, 1/60)
Frame size: 640x360 (1/1, 1/2, 1/4, 1/5, 1/10, 2/25, 1/15, 1/25, 1/30, 1/40)
Frame size: 640x480 (1/1, 1/2, 1/4, 1/5, 1/10, 2/25, 1/15, 1/25)
Frame size: 1280x720 (1/1, 1/2, 1/4, 1/5, 1/10, 2/25)
Frame size: 1920x1080 (1/1, 1/2, 1/4, 1/5)
Frame size: 3840x2160 (1/1, 1/2)
In some test cases, it is useful to allow for higher frame rates, as
configurations such as 720p@30 FPS have become commonplace now.
This patch allows:
0- 719p - 120fps
720-1079p - 60fps
1080-2159p - 30fps
2160p - 15fps
