It's a better format and we have an encoder for it, so it doesn't fail
like CODEC_ID_TEXT.

Specifically crafted samples can reinit ogg->streams[] while
reading samples, and thus we should not cache old pointers since
these may no longer be valid.

According to MPEG-TS specs, the continuity_counter shall not be

This variable is set to the same value for all directories.
Adding the -L flags directly to LDFLAGS is simpler and achieves
the same thing.

This prevents a crash when seeking.

This fixes a crash when seeking in some webm files with many
threads (e.g. 8).

FF_COMMON_FRAME holds the contents of the AVFrame structure and is also copied
to struct Picture.  Replace by an embedded AVFrame structure in struct Picture.

ptrdiff_t can be 4 bytes, which leads to the next element being 4-byte
aligned and thus at a different offset than intended. Forcing 8-byte
alignment forces equal offset of dither16/32 on x86-32 and x86-64.

This reduces startup latency for make invocations, which is especially
noticeable on systems that are slow or have slow I/O, like Windows.

Declaring tools associated with each library in their respective
makefiles allows these tools to easily depend on the correct
prerequisites and link against the libs they need.

This macro can cause problems in conjunction with the bitdepth
template expansion.  It was presumably added to keep source
compatibility when high bitdepth support was added.  However,
emulated_edge_mc is a dsputil pointer and should not be called
directly, so there is little reason to keep such a macro.

Deprecate avcodec_alloc_context/2.

It should be replaced with proper per-codec defaults.

Deprecate corresponding AVCodecContext option.

This is the first test of decoder private options.

It supports passing options to codecs.

Adds support for decoder-private options and makes setting other options
simpler.

In testing, the file output plugin gave a max buffer size of about 20 million
frames, which is way more than what is really needed and causes a memory
allocation error on my system.

buffer_size/4 is the value used by aplay. This fixes output to null
devices, e.g. writing ALSA output to a file.

Instead, just decrease it to a valid value and use that.

Set DV packet durations using fields_per_frame.
This requires turning gxf_stream_info into the demuxer's context for access to the value in gxf_packet().
Since MPEG-2 seems to work fine this done only for DV.
