This consists of
P1) kmsgrab updated to pickup format_modifier using drm getfb2,
provided
the user has not explicitly set a format_modifier and
GetFB2 is part of xf86drmMode.h
Apply this patch set.
P2) hwcontext_drm updated to detile known tile layouts, when user
tries to get data from it. This uses the fbtile helper routines.
fbtile has been configured by default to be non-public and thus is
included into hwcontext_drm.c
fbtile now supports both tiling as well as detiling of supported
tile layouts. It also supports av_frame_copy_with_tiling, its
named as fbtile_frame_copy.
If required in future, one can expose fbtile as a public api by
defining FBTILE_SCOPE_PUBLIC, while compiling.
Apply this patch set.
P3) video filters vf_fbtiler and vf_hwdownload (with detile)
This is provided just for reference, in case someone is interested.
It supports fbtile compiled either as a public api or internal api.
This is a optional patch set.
