Also this hypothetical bug report would include similar behavior with
mpeg1video in MOV: By default it uses "m1v1", which is unplayable, but
"-vtag mp1v" seems to produce usable output. The other output formats
tested are fine by default, with the AVI using "mpg1". Encoding fails
similarly with "-vtag mp1v -f mov" and "-vtag mpg1 -f mov". It's basically
the same issue but with 1's instead of 2's. Same open questions.
