#10385(undetermined:new): ddagrab fails on Windows if adapter ID is specified
#10385: ddagrab fails on Windows if adapter ID is specified -------------------------------------+------------------------------------- Reporter: Jøger | Type: defect Hansegård | Status: new | Priority: normal Component: | Version: 6.0 undetermined | Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: Screen capturing on Windows with ddagrab fails if adapter id is specified on non-UWP build. Root cause is likely that CreateDXGIFactory is used, not CreateDXGIFactory1. Desktop duplication API appears to be incompatible with DXGI factories prior to 1.1. See also https://learn.microsoft.com/en-us/windows/win32/api/dxgi1_2/nf- dxgi1_2-idxgioutput1-duplicateoutput which specifies that IDXGIOutput1::DuplicateOutput fails with E_INVALIDARG if the device was not created from IDXGIFactory1 (or a later version of a DXGI factory interface that inherits from IDXGIFactory1). How to reproduce: {{{ ffmpeg -init_hw_device d3d11va:0 -filter_complex ddagrab -c:v h264_nvenc -cq:v 20 output.mkv -loglevel debug ffmpeg version 6.0 built on Windows, MSYS2 }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/10385> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
