In d3d11va_create_staging_texture(), during the hwmap process, the ctx->internal->priv is not initialized, resulting in the texDesc.Format not initialized. Now pass the format value from d3d11va_transfer_data() to fix it. $ ffmpeg.exe -y -hwaccel qsv -init_hw_device d3d11va=d3d11 \ -init_hw_device qsv=qsv@d3d11 -c:v h264_qsv \ -i input.h264 -vf "hwmap=derive_device=d3d11va,format=d3d11,hwdownload,format=nv12" \ -f null - Signed-off-by: Tong Wu <tong1.wu@intel.com> --- libavutil/hwcontext_d3d11va.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-)
