It is not generally possible to read mov files via stdin,
because it is perfectly normal that mov files contain
necessary information needed for decoding (like codecs
etc.) at the very end of the file.
(This is not a limitation of FFmpeg, but a feature of the
mov file format.)

That is extremely unlikely / you tested a different mov
If you have a mov file that allowed in the past to be
read via stdin but does not work anymore, please share
a sample (there may be a bug), but remember that what
you want (reading all files via pipe) cannot work in
