Description Vadim Rutkovsky 2015-03-31 13:12:14 UTC 
Cheese shows 'There was an error playing video from then webcam' after I switch 'Photo resolution' from 1280x720 to 960x540. Stdout says:

libv4l2: error got 4 consecutive frame decode errors, last error: v4l-convert: error resolution is not a multiple of dctsize
(cheese:18917): cheese-WARNING **: Failed to allocate a buffer: gstv4l2src.c(755): gst_v4l2src_create (): /GstCameraBin:camerabin/GstWrapperCameraBinSrc:camera_source/GstBin:bin35/GstV4l2Src:video_source

Note, that compatible resolutions (e.g. 640x480) work correctly, so Cheese should either check which resolutions are compatible or revert to previously set resolution.

Cheese also doesn't restore preview after resolution is not changed, so I have to restart it all the time

Reproduced on t440s with packages:
cheese-3.14.2-1.el7.x86_64
libv4l-0.9.5-4.el7.x86_64
xorg-x11-drv-v4l-0.2.0-35.el7.x86_64

This is very likely a duplicate of bug 722165, and probably a bug in libv4l2.
