Bug ID: 110443
Summary: vaapi/vpp: wrong output for non 64-bytes align width
(ex: 1200)
Product: Mesa
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/radeonsi
Assignee: dri-devel@lists.freedesktop.org
Reporter: julien.iso...@gmail.com

vaDeriveImage reports wrong stride.
Indeed Mesa's vlVaDeriveImage always sets the stride to w * 4 for RGBA format
https://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/state_trackers/va/image.c#n259
This results in wrong video output, see
https://gitlab.freedesktop.org/gstreamer/gstreamer-vaapi/issues/100
Is there a way to know the pipe_resource's stride
https://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/state_trackers/va/image.c#n283
without exporting it to dmabuf (through whandle.stride) and without mapping it
(drv->pipe->transfer_map / pipe_transfer.stride) ?
