Usage: ${self_basename} <path_to_dir_containing_tests>

This script decodes all .ivf files in the given directory, taking an md5sum of
each frame, and comparing the md5sums to known good values in the corresponding
.ivf.md5 file.

Options:
    --help                      Print this message
    --codec=<name>              Codec to pass to example [vp8]
    --exec=<name>               Name of executable to run [./vpxdec]
    --show-fail                 Identifies which frames fail the test
    --threads=<num>             Choose the number of threads to use
