The encoder produces files that are no longer compatible with previous
versions of the decoder, and may actually cause decoding issues for other
software, so indicate that change to allow decoder quirks.

Fix a segfault with large window size.

The framework can ensure that each input frame has exactly
the correct number of samples, except the last one.

The packet buffer allocation considered as dct-coded, while it is
actually run-coded and thus requires a larger buffer.

It is always identical to the last pushed frame.
The samples in the last incomplete window were ignored,
this is unchanged.
Possible enhancement: pad the last incomplete window with
silence.

SMPTE 268M-2003 specifies that each line starts at a 4-bytes boundary.
Therefore, modify correspondingly the input buffer strides and size.

Partially fixes ticket #3692: DLAD_8b_3c_big.dpx still has inverted
colors, which might be related to endianness.

S268M-2003 specifies that each line start is aligned on a 4-byte boundary.
Reviewed-by: Paul B Mahol <onemda@gmail.com>

It is basically a wrapper around av_get_audio_frame_duration(), with a
fallback to AVCodecContext.frame_size. However, that field is set only
when the stream codec context is actually used for encoding or decoding,
which is discouraged.

For muxing, it is generally the responsibility of the caller to set the
packet duration.
For demuxing, if the duration is not stored at the container level, it
should be set by the parser.

Therefore, removing the frame_size fallback should not break any
important case.
