I can't come up with a nice way to handle this. It's hard to keep the
lock-stepped input/output in this case. You can't predict whether the
MMAL decoder will output a picture (because it's asynchronous), so
you have to assume in general that any packet could produce 0 or 1
frames. You can't continue to write input packets to the decoder,
because then you might get too many output frames, which you can't
get rid of because the lavc decoding API does not allow the decoder
to return an output frame without consuming an input frame (except
when flushing).

The ideal fix is a M:N decoding API (preferably asynchronous), which
would make this code potentially much cleaner. For now, this hack
will do.

That loop is completely stand-alone.

Matches the openjpeg behaviour.

Ensure that the components are ordered consistently, ie. always
RGB(A) and YUV(A). This allows to identify a specific plane on a given
pixel format without hard-coding knowledge of the plane order.

There is no practical benefit in having this structure elements
bit packed given the size of the structure and its usage.
Change types from uint16_t (packed) to plain int in order to simplify
modifying the structure and accessing its fields.

The previous restriction was partially designed to fix certain
(broken) samples from bug 215. There should be no restriction on the
number of keyframes per fragment or trun.

The spec suggests that all frames lacking MOV_FRAG_SAMPLE_FLAG_IS_NON_SYNC
are key frames, but we require the flag MOV_FRAG_SAMPLE_FLAG_DEPENDS_YES
to be unset as well. This works for (possibly broken) media that never
sets the NON_SYNC flag and should also be correct for any spec-compliant
file.

For files that never set either of the flags, all samples are marked
as keyframes.

Do not make many assumption on the dimension of the slices and just
try to decode additional lines if there is enough data left.

Despite '417792' being reported in the binary decoder, the buffer at
encoding time needs to be bigger to avoid running out of space due to
interlace handling.

It is useful to support a future staging branch and to have an
