Only compile if CONFIG_ENCODERS is enabled, i.e. if at least one
encoder is to be compiled. This prevents it from being includes in
a decoder-only build.

dct_bits is never set except in h264, where it is never used, thus
remove it. Then, remove all functions that were set based on non-zero
(32) values for dct_bits. Lastly, merge 9-14 bpp functions for get_pixels
and draw_edge, which only care about pixel storage unit size, not actual
bits used (i.e. they don't clip).

Our previous release (1.1) contained a version 54 libavdevice
and this version here is not ABI compatible thus a bump is
needed

This reverts commit 9efcfbed.

All the shame on me; this commit is actually causing more problems
(broken outputs but also crashes) than it was solving.

Before this change, the audio input and output formats are set
independently, so the lavfi negociation could pick different settings
for the input and output. This is particularly true for the channel
layout settings, where multiple choices were available.

Fixes Ticket2342.

This makes possible the raise of one picture if the input has less than
the number of frames to analyze.

Fixes Ticket1992.

Since the conversion to refcounted frames, the tiff decoder
only wrote the metadata into its internal "picture" in its own context,
never exposing the metadata to the user, and eventually leaking the
metadata.

Instead, properly store the metadata directly into the frame being decoded into.

Always use the special filter for the first and last 3 columns (only).

Changes made in 64ed3976 slowed the filter to just under 3/4 of what it
was.  This commit restores the speed while maintaining identical output.

This allows reporting missing features and requesting samples from
all libraries in a standard way; with a simplified API.

This field was only ever set and freed from avcodec, and not otherwise
used. However, because frames are refcounted now, avcodec cannot make any
assumptions about the lifetime of the frame metadata, which can result in
double-frees or leaked memory.

The tool nowadays supports more than one track per file,
this makes reading the code slightly less confusing.
