We keep INIT_AVX (for backwards compatibility). 3arg AVX ops with
a memory arg can only have it in src2, whereas SSE emulation of
3arg prefers to have it in src1 (i.e. the mov). So, if the op is
symmetric and the wrong one is memory, swap them.

Earlier, sc->samples_per_frame was used for setting the frame size,
but all files don't have that set properly. The frame size is a
known constant for these codecs.

If frame_size isn't set, the mov/3gp muxer refuses to mux it.

This fixes stream copy of audio from
https://roundup.libav.org/file1248/Video_With_AMR-NB_Audio.3gp
to another 3gp file (roundup issue 2468).

The vertical scaler handles 2 rows at a time and thus requires
alignment by 2, or else it'll read invalid memory and result in
corrupt output.

Fixes the following conformance suite samples:
HCBP1_HHI_A.264, HCBP2_HHI_A.264, HCMP1_HHI_A.264 (main)
HCHP1_HHI_B.264, HCHP2_HHI_A.264, HCHP3_HHI_A.264 (frext)

These packets are valid packets, and consist of 1 byte (which
contains the mode bits).

This had been analyzed and reported by Igor Levin, igor d levin comverse com.

our own using pthreads (or w32pthreads).

This function used to set codec_type. With the current fallback
implementation based on avcodec_get_context_defaults3, codec_type
won't be set to the value passed in, but will be set to
AVMEDIA_TYPE_UNKNOWN. Legacy callers of this function might expect
this field to be set to the value passed in.

If attribute_deprecated is used in an enum declaration, it
should follow the 'enum' keyword, otherwise it's ignored
silently. This is the only case of attribute_deprecated for
enum declarations currently.

Currently, this attribute_deprecated doesn't have any effect.
If moved to the right place, it emits a warning every single
time avcodec.h is included, like this:

avcodec.h:2827: warning: ‘AVLPCType’ is deprecated (declared at avcodec.h:543)

There is already a working attribute_deprecated for the
corresponding field in AVCodecContext, so therefore this
one shouldn't be needed.

It allows attaching arbitrary files, e.g. fonts to Matroska files.

The calling convention only allows 4 non-stack parameter, with each
float or int register being skipped if not used.
