seems git doesnt like applying this: Applying: avcodec/cuvid: Add support for P010 as an output surface format fatal: sha1 information is lacking or useless (libavcodec/cuvid.c). error: could not build fake ancestor Patch failed at 0001 avcodec/cuvid: Add support for P010 as an output surface format The copy of the patch that failed is found in: .git/rebase-apply/patch When you have resolved this problem, run "git am --continue". If you prefer to skip this patch, run "git am --skip" instead. To restore the original branch and stop patching, run "git am --abort".
