Hello I compiled vcu control decoder app using xilinx sdk 2019.1 and I'm running it on ultrazed ev carrier card with petalinux 2019.2. VCU works because using I can encode or decode video using gstreamer. But if I execute vcu-ctrl-decoder_debug.elf I have this error:

./vcu-ctrl-decoder_debug.elf -avc -in testcut.
