> - CHECK_CU(cuMemsetD8(s->data, 0, HIST_SIZE * sizeof(int))); > + CHECK_CU(cu->cuMemsetD8Async(s->data, 0, HIST_SIZE * sizeof(int), > s->cu_stream)); Hi Phil, the only problem I encountered was the cuMemsetD8Async function which needs yet to be added to the ffnvcodec headers. The other filters are building fine (MSYS2/Win). -- softworkz _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel
