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)

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

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

mpegts: When playing mpegts over rtp/rtsp/sdp, lavf must still read PAT/SDT to get available streams

The code path using for mpegts over rtp doesn't open the demuxer using
mpegts_read_header,
so it never starts listening for PAT/SDT, only uses auto_guess
