I dont know on which system the prior check failed but an advanced
linker on some platform might have optimized func() out as unreachable.

This makes it rememember old values should the stream not
contain new values for these for each subtitle.

This fixes overwriting x264 preset settings for flags2 based options.
See https://ffmpeg.org/trac/ffmpeg/ticket/448

This avoid retrying to read ASF index in files for every
attempt to seek. This makes a big difference to protocols
with slow seeking (for example http)

These changes were forgotten in commits:
  lavfi: simplify signature for avfilter_get_audio_buffer() and friends
  (commit 2c031741)
and
  lavfi: consistently use int for sample_rate in AVFilterLink and AVFilterBufferRefAudioProps
  (commit 4381bddc)

This fixes https://ffmpeg.org/trac/ffmpeg/ticket/448 - at least for
rc_lookahead. A similar problem still exists for the flags2 based
options.

This is how mkv's store palette information for vobsubs

Also consistent with AVCodecContext.sample_rate. Simplify/avoid
pointless type checks and conversions.

Breaks audio API/ABI.

The additional parameters were never used and are complicating the
function interface. Also, they were inconsistent with the way the
video API works.

So this assumes that a requested samples buffer will have *always* the
format specified in the requested link.

This breaks audio filtering API and ABI.

mxfdec: skip to end of structural sets This fixes reading of partition packs. The code stops reading after the operational pattern and should skip the array of essence container labels that follow

Ignore another filetype, as generated by Microsofts lib.exe when creating the import libraries.

Move shared tables to a separate file as well.

This prevents some crashes when corrupted bitstream reports e.g. P-type
slice in I-frame. Official RealVideo decoder demands all slices to be
of the same type too.

The move of avio_seek in avi_read_seek is to avoiding modifying
