7fa5f9990b Extend init_loop_filter to work for filter limit values up to 127 instead
of only up to 64. 127 is the maximum value allowed by the theora specification.

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.

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.

fe022ce2f8 Fix libx264.c to not drop SEI userdata from x264 encoder.
Most muxers in ffmpeg ignore the SEI if it is placed in extradata, so instead
it has to be catted to the front of the first video frame.

822d0a6e0c Drop code that attempts to decode frames that are prefixed by junk.
Too often it ends up decoding random data into noise without detecting
it (for example after seeking of some MP3 data with oddly often occurring
startcode emulation).
