# Usage: make fuzz # fuzz all foramts
# Usage: make fuzz GROUP=mp4 # fuzz a group (each format is a group also)
# TODO: as decode recovers panic and "repanics" unrecoverable errors this is a bit hacky at the moment
# fuzz code is not suppose to print to stderr so log to file
# Retrigger:
# try to decode crsash with all formats:
# cat format/testdata/fuzz/FuzzFormats/... | go run dev/fuzzbytes.go | go run . -d raw '. as $b | formats | keys[] as $f | $b | decode($f)'
# convert crash into raw bytes:
# cat format/testdata/fuzz/FuzzFormats/... | go run dev/fuzzbytes.go | fq -d raw 'tobytes | tobase64'
