Mark Thompson	6e951d0cf8	kmsgrab: Add more supported formats X2RGB10 tested on both Intel Gen9 and AMD Polaris 11. NV12 tested on Intel Gen9 only - since it has multiple planes, this requires GetFB2. Also add some comments to split the list up a bit.	4 years ago
Mark Thompson	ff14858a60	kmsgrab: Don't require the user to set framebuffer format This is provided by GetFB2, but we still need the option for cases where that isn't available.	4 years ago
Mark Thompson	ef934dba2d	kmsgrab: Use GetFB2 if available The most useful feature here is the ability to automatically extract the framebuffer format and modifiers. It also makes support for multi-plane framebuffers possible, though none are added to the format table in this patch. This requires libdrm 2.4.101 (from April 2020) to build, so it includes a configure check to allow compatibility with existing distributions. Even with libdrm support, it still won't do anything at runtime if you are running Linux < 5.7 (before June 2020).	4 years ago

Carl Eugen Hoyos	5cb70381d9	lavd/kmsgrab: Remove the mapping for AV_PIX_FMT_RGB8. The definitions are different: 3:3:2 vs 2:3:3.	7 years ago

Mark Thompson	9f9625ea80	kmsgrab: Remove multiple-plane formats The planes are unlikely to be contiguous, assuming they are results in very broken output. (Tested with NV12/NV16 on Rockchip.)	7 years ago
Mark Thompson	22afa87a8e	kmsgrab: Fix DRM format definitions All DRM formats are defined in terms of little-endian words, so RGB formats like XRGB actually have the elements in the opposite order order in memory to the order they are in the name. This does not affect YUYV and similar YUV 4:2:2 formats, which are in the expected order.	7 years ago
Jun Zhao	462568185b	kmsgrab: Fix build failure with old libdrm DRM_FORMAT_R8 was added in libdrm 2.4.68. DRM_FORMAT_R16 was added in libdrm 2.4.82. Signed-off-by: Jun Zhao <jun.zhao@intel.com> Signed-off-by: Mark Thompson <sw@jkqxz.net>	7 years ago
