This prevents sending a packet with data=NULL size=AVERROR_EOF.

The decoder shouldn't be allocating coded_frame. It's also cleaner to split
them than to check avctx->codec->encode and avctx->codec->decode.

Use uintptr_t instead of plain int.  Without this change, the
comparisons will come out wrong for pointers in certain ranges.
Fixes random failures on ppc64.  Also fixes some compiler warnings.

On 32-bit ppc, the GOT pointer must be loaded manually.
This adds a "get_got" assembler macro to compute the
GOT address.  The "movrel" macro is updated to take an
additional parameter containing the GOT address since
no register is reserved for this purpose on ppc32.
These changes have no effect on ppc64 builds.

The initial sample of each block is raw 16-bit PCM, not DPCM.
Fixes decoding of all samples in:

If the demuxer did not set a codec_tag, there is none and
inventing one makes no sense.  This change stops the rawvideo
"decoder" over-writing user-supplied pixfmt with one derived
from the codec_tag.  The pixfmt-codec_tag-pixfmt round-trip
is lossy since several pixfmts map to the same codec_tag.

This fixes fate-lavf-pixfmt with avfilter disabled.

On allocation, the array length is multiplied by sizeof(int64_t),
this prevents the multiplication from overflowing.

Back in 2002 when it was added, some muxers used information from
coded_frame. It's not true anymore, so this hack is useless and can be
removed.

When using suncc to build, the Solaris linker will mark
an executable with each instruction set encountered by
the Solaris assembler.  As our libraries contain their own
guards for processor-specific code, instead suppress
generation of the HWCAPS ELF section on Solaris x86 only.

Unfortunately the output buffer size check assumes that the
input buffer is never over-consumed, thus this actually
also allowed to write outside the output buffer if "lucky".

All other codecs use lowercase names in that field.

This is a raw demuxer for the AAC LATM decoder and thus limited to
single stream LOAS.

CODEC_CAP_DELAY set.

Make the iff demuxer send the whole audio chunk to the decoder as a
single packet and move stereo interleaving from the iff demuxer to the
decoder.
