As the comment in the code mentions, EAGAIN is not an expected value here
because we call avcodec_receive_frame() until all frames have been returned.
avcodec_send_packet() returning EAGAIN means a packet is still buffered, which
hints that the underlying decoder is buggy and not fetching packets a

The tag comes from samples/ffmpeg/mov/unrecognized/bartjones.mov
really looks like some random data. Now the random tag matched
another file, which isn't a mov.

When no drawing is to be performed, tpad can work fine with
hardware frames, so advertise this in the query_formats
callback and ensure the drawing context is never initialised
when just cloning frames.
