82c9182fe3 If the end of the input buffer is reached while decoding MJPEG and at least
a valid SOF was found, emulate an EOI.
This allows e.g. to at least decode the available part of incomplete MJPEG frames.

1496b04c28 Make the MJPEG decoder return -1 when no image was decoded so that decode
errors are actually recognizable as such.

643fd8a198 Add a got_picture flag to MJpegDecodeContext which indicates if its picture
element is valid. Skip the code handling SOS and EOI if not, since it can not
work without a valid AVPicture.
This fixes a crash with mjpeg/smclockmjpeg.avi.1.0 from issue 1240 where the
decoder returned an invalid AVPicture.

b27bf2a7b4 mjpegdec: check that the coded dc_index and ac_index have a valid associated VLC table.
Removes some disabled dc_index/ac_index checking code that seems to have had
some undocumented issues and should not really be necessary anymore now.
Fixes from issue 1240 the files mjpeg/smclockmjpeg.avi.1.10 and mjpeg/smclockmjpeg.avi.1.171.

0410ee8f86 H.264: Don't set data_partitioning for invalid NAL_DPA.
Before, the decoder could interpret a corrupt frame
as a NAL_DPA and NAL_DPC, and then start decoding
even if decode_slice_header() returned an error.
This frequently caused crashes.

Fixes issue1228, issue1229, and partially issue1238.

ec62d942ea Fix potentially unaligned accesses in ff_copy_bits()
A pointer should never be assigned a value which may have less than the
required alignment of the target type.  Compilers may assume pointer
values have the required alignment, and emit normal load/store instructions.

Unaligned pointers should use a character type or compiler-specific
type modifiers.

Too often it ends up decoding random data into noise without detecting
