When input one of JPEG picture to Tegra multimedia API sample jpeg_decode.
Program die and cannot catch exception.

How can I avoid program dying program ?

Please apply attached patch to NvJpegDecoder class and run

06_jpeg_decode$ ./jpeg_decode num_files 1 ng.jpg test.raw --decode-buffer

‘–decode-fd’ is not supported due to limit of HW alignment.
