28db30aa29 avf: fix audio writing in the output-example
av_init_packet does not reset data and size fields in AVPacket,
avcodec_encode_audio2 can use preallocated AVPacket.

3e1ff8eb27 img2dec: Recognize glob meta chars only if prefixed by %
This changes globbing support to only be used if the character
contains at least one glob meta character that is preceded by
an unescaped %. To escape a literal % one would use %% which is
identical to the way to match a % with image2 sequence generation
feature.

* Makes it possible to have patterns like %04d-[720p].jpg work
  again with sequence number generation. Previously this would
  always be detected as a glob pattern and was interpreted by
  the image2 glob code instead.

* Makes it possible to use %*-[720p].jpg to match above pattern
  without having to double escape it to be not interpreted by most
  shells and not by the image2 glob code (previously one would
  need to use \*-\\\[720p\\\].jpg to achieve the same)

b7b1509d06 truemotion: forbid invalid VLC bitsizes and token values.
SHOW_UBITS() is only defined up to n_bits is 25, therefore forbid
values larger than this in get_vlc2() (max_bits). tokens[][] can be
used as an index in deltas[], which has a size of 64, so ensure the
values are smaller than that.

This prevents crashes on corrupt bitstreams.

9bd41bb191 configure: Check for a different SDL function
This one is available both in SDL 1.2 and in 1.3 (which is the current
version available e.g. in macports), while 1.3 doesn't contain
SDL_Linked_Version().

The current check for SDL_Linked_Version() (available since SDL 1.2.13)
was added in 8f1b06c8, because including the headers for SDL_Init()
redirects the main() function, requiring the main function signature
to match the one of SDL_main (including argc/argv).

a05c41acd1 mp3dec: perform I/S and M/S only when frame mode is joint stereo.
Looks like some LAME versions produce dual stereo mode MP3s with
flags for intensity and middle stereo set. In this mode those flags
should be ignored like the reference decoder and derived ones do.

e5c3b51cd1 ffmpeg: disable dr1 when frame sizes change.
dr1 seems to work fine with frame size changes but many filters
cant handle it yet. Simply disabling it forces the alternative
non dr1 code path which has been tested more completely and
is known to handle frame size changes in a wider varity of
cases.

2efb710a34 build: fix doc generation errors in parallel builds
The $(dir) function used to construct OBJDIRS includes a trailing slash
in the names returned, which GNU make 3.82 does not match to the
slash-less 'doc' in the documentation dependencies, causing parallel
build to fail.  Adding a slash fixes this and still works with make
3.81.
