This commit causes problems for vlc, see https://trac.videolan.org/vlc/ticket/5518

This reverts commit 475fb67d.

Fixes a crash with the sample from Ubuntu bug #869125.

Fixes ticket #579 at least for ffplay.

Fixes ticket #617.

Changing the lowres value is risky because the user application may have a
local copy and not read back into it, or not undo some lowres dependant things.
A patch implementing this in ffplay is already on ffmpeg-dev, so this feature
should be back soon.

This reverts commit 125ea3ee.

* qatar/master:
  avformat: Avoid a warning about mixed declarations and code
  BMV demuxer and decoder
  matroskaenc: Make sure the seekhead struct is freed even on seek failure
  mpeg12enc: Remove write-only variables.
  mpeg12enc: Don't set up run-level info for level 0.
  msmpeg4: Don't set up run-level info for level 0.
  avformat: Warn about using network functions without calling avformat_network_init
  avformat: Revise wording
  rdt: Set AVFMT_NOFILE on ff_rdt_demuxer
  rdt: Check the return value of avformat_open
  rtsp: Discard the dynamic handler, if it has an alloc function which failed
  dsputil: use cpuflags in x86 versions of vector_clip_int32()

Actually check the return value of DecodeBegin, to make

Remove the CODEC_CAP_LOSSLESS flag, as it doesn't make
any sense for a decoder to use it.

Since buf_size is only used in this one function, there
is no reason for it to be part of UtVideoContext.

The caller expects the seekhead struct to be freed when calling
matroska_write_seekhead. Currently, the structure is leaked if the
seek fails.

run: The number of zero coefficients preceding a non-zero coefficient,
in the scan order. The absolute value of the non-zero coefficient is
called "level".

The run-level code makes illegal reads when trying to set up tables for
nonsense level 0.

Width and height, as used in utvideo_decode_frame, do not

It might make sense not to make the function completely mandatory
immediately at the next bump, which might be quite soon after
the function was introduced.

The original format field in Ut Video's extradata
should not be used to determine the output format.
Cases can occur where the original format differs
from the actual current format, and thus should
not be used as the output format. Instead, rely
solely on the FOURCC.

The new design allows to specialize the format for continuos time values
and discrete values. In particular, allows to print integer values like
"12" rather than "12.000".

Prettify, simplify parsing for integer values.

Help readability.

This makes rdt work again, which has been broken since
603b8bc2. This commit made
opening a demuxer without a file (or in this case, with a filename
which can't be opened) fail, unless the demuxer actually declared
AVFMT_NOFILE.

If it failed, return NULL. This avoids trying to use an
half-initialized RDTDemuxContext.
