This option can be used to select useful frames from an ffconcat file which is
using inpoints and outpoints but where the source files are not intra frame
only.

If duration is still AV_NOPTS_VALUE when opening the next file, we can assume
that outpoint is not set.

  qsvenc: factor out common options
Merged-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

Fixes a floating point exception when width and height are not supplied
(and therefore are zero).

Calculate packet size only once, and propagate errors earlier in the chain.

Also remove use of the deprecated av_image_get_buffer_size().

More readable and less breakable.

avcodec/mpegvideo_enc: Remove slice structured mode from H.263 as well as the code automatically enabing it

There is no such thing as a slice structured mode in the original version 1  H.263,
that mode was added in H.263+ in 1998. Also the headers for slice structured mode
are not part of the older version 1 and this would result in unplayable files

An alternative to this patch would be to merge the H263 and H263P AVCodecs and use
other means to distinguish the older and newer versions.

This actually fixes an incorrect float literal. It is believed by
examining the precision that the literals were all pre-computed as
floats, resulting in this needless loss of precision. There is no
benefit to keeping such reduced precision:
1. These constants are used for static array computation, hence
compile-time.
2. They will be treated as doubles anyway, since f specifier was not
present.

This uses M_SQRT1_2, M_SQRT2 instead of the actual literals. This yields
greater precision in some places in avcodec/ac3, while fixed point
values remain unchanged.
