Subject: [PATCH 3/4] Fix cheese_camera_device_update_format_table() going
|
|
|
e650a0d |
into an infinite loop
|
|
|
e650a0d |
|
|
|
e650a0d |
Some devices report a very small min_width / height down to reporting
|
|
|
e650a0d |
0x0 as minimum resolution, which causes an infinte loop in
|
|
|
e650a0d |
cheese_camera_device_update_format_table().
|
|
|
e650a0d |
|
|
|
e650a0d |
This patch limits the minimum resultion to 160x120, both to fix the
|
|
|
e650a0d |
infinite loop issue, and to remove ridiculous resolutions such as
|
|
|
e650a0d |
2x2, 5x3, 11x7, 22x15 etc. which are seen in the resolution drop down on
|
|
|
e650a0d |
some devices.
|
|
|
e650a0d |

|
|
