apport information
** Tags added: apport-collected plucky
** Description changed:
since upgrading to noble, sometimes the following bit of code works
instantaneously, and sometimes it takes ~5 seconds to report:
** (gst-plugin-scanner:692358): CRITICAL **: 10:55:31.508:
_dma_fmt_to_dma_drm_fmts: assertion 'fmt != GST_VIDEO_FORMAT_UNKNOWN'
failed
code:
>>> import cv2
>>> vc = cv2.VideoCapture('/dev/video2')
when it takes a long time and reports the assertion error, I see the
following in journalctl logs (so maybe an amd/kernel bug instead of an
opencv bug? -- also fwiw am on a hybrid amd/intel system where
DRI_PRIME=1 generally activates the amd card but this should be running
w/out DRI_PRIME set):
