This explicitly disables threading for encoding as slices are otherwise
automatically activated.  This should be dropped once option resetting
between files is fully implemented.

This adds a comment field to the report header, suitable for

This is useful e.g. for building in a different filesystem than
where the source is kept.

Since a private class is set for this muxer, the callers will
assume that the private data starts with an AVClass pointer.
If no such member exists, the first few bytes of the struct
will be overwritten, and the class pointer may be broken at
any later time.

Require the presence of opencv/cxcore.h in place of opencv/cxtypes.h,
which has been removed. Fix compilation with libopencv > 2.1.0.

Fix trac issue #221.

Fix warnings:
cmdutils.c: In function ‘opt_default’:
cmdutils.c:304: warning: initialization discards qualifiers from pointer target type
cmdutils.c: In function ‘set_context_opts’:
cmdutils.c:431: warning: passing argument 2 of ‘alloc_priv_context’ discards qualifiers from pointer target type
cmdutils.c:414: note: expected ‘struct AVClass *’ but argument is of type ‘const struct AVClass *’

Also remove -x264opts item from the ffmpeg manual, since it belongs to
the encoders section.

Make Audio Encoders a separate chapter, and decrese the contained
sections level by one.

Improve rendering, and improve consistency with the other parts of the
manual.

Muxers are not used by ffprobe.

Fix leak.

Avoid the presence of an invalid pointer, fix a crash in case of
get_filtered_frame() failure.

The check is no more required since recent changes in the
avfilter_unref_buffer(), the check is done in the function.
Simplify.

Fix compilation.

When backing up the top-left border, check that the top-left
(rather than left) MB indeed does belong to our slice. If it
doesn't, backing up has no positive effect but may accidentally
interfere with other threads writing in the same space.

Fixes occasional one-off effects when enabling slice-MT.

The prototype should use the same typedefs as the definition, or it
will fail where int32_t is not int (DOS apparently).

The new function is a wrapper around
av_vsrc_buffer_add_video_buffer_ref(), and allows to simplify the act
of pushing AVFrame data to the source buffer.

Avoid the need of two distinct av_vsrc_add_video_buffer_ref*
functions. Simplify the interface.

Simplify passing AVFrame data to av_vsrc_buffer_add_video_buffer_ref().

Rename av_vsrc_buffer_add_frame to
av_vsrc_buffer_add_video_buffer_ref(), and change its inteface to make
it accept in input an AVFilterBufferRef rather than an AVFrame.

This way the interface can be used without requiring the
inclusion/installation of libavcodec headers.

This is consistent with how all other table generation programs are named.
Moreover this ensures that the cos table generation program is correctly
deleted when cleaning the tree.

tableprint.c serves little purpose on its own and removing it allows building
the table generator programs with the normal HOSTPROGS Makefile rules.

This collapses the make rules for the trig tables into a pattern
rule.  Based on a patch by Diego, modified to avoid using fragile
make constructs and allow future addition of fixed-point sin tables.

Older nasm versions have trouble assembling certain AVX instructions, but the
current AVX check did not detect this. Update the check to use an instruction
that triggers the nasm problem.
