No you can't. ffprobe will not check the whole file for integrity.
Someone could make a file in which the first 20MiB would look like a
correct file and then stick 20GiB worth of null bytes on the end.
Or more likely there is a small corruption in the middle of the file
which causes an unrecoverable error when decoding causing ffmpeg to abort.
