- Add special cases for offsets of 2, 3, or 4 bytes.  This means the
  offset is always >4 in the generic case, allowing 32-bit copies to
  be used there.
- Don't use memcpy() for sizes less than 16 bytes.

Current code would incorrectly process e.g. 'ff 00 ff 00 ff' to
'ff ff ff', while it should be 'ff ff 00 ff'.

Fixes Bug 395.

The vertical offset mask 0x07 is suspicious.

    v_off = FFMIN(data[2] & 0x07, CDG_BORDER_HEIGHT - 1);

Note that v_off is up to 11 (CDG_BORDER_HEIGHT - 1), the correct mask
should be 0x0F.

The following error handling is broken due to signedness.

    int file_size;
    uint32_t tag_bytes;
    int64_t tag_start;
    ...
    tag_start = file_size - tag_bytes - APE_TAG_FOOTER_BYTES;
    if (tag_start < 0) { ... }

Note that tag_bytes is unsigned, which makes the right-hand side of
`tag_start = ...' unsigned, too.  The 32-bit unsigned value is then
zero-extended to 64 bits.  Therefore, tag_start must be non-negative,
and the check (tag_start < 0) is always false, which breaks the error
handling.  This patch fixes the check.

The sample count is decremented by the DECODE() macro and needs to be reset
in each loop iteration. Also, DECODE() increments the src pointer so that does
not need to be done separately.

It is pleonastic and was used in stale functions pending replacement.

All the non deprecated functions are in avpicture.c now.

This will distinguish ALAC 16-bit tests from ALAC tests with other bit
depths.

Function names changed after switching to declaration with
PRED4x4/8x8/8x8L/16x16 macros in the C code.

pts should be that of the packet containing the presentation segment.

This is (erroneously) required to enable various things in the

Fixes crashes on Win32 and stack overruns on x86-32 in general.

If there are any samples remaining in the output fifo from previous conversion
calls, we have to output those samples first instead of doing direct output
of the current samples.

A bug in tail call optimisation in gcc 4.3 and later on parisc causes
numerous tests to fail.  Disabling this optimisation gives a working
build.  See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55023Signed-off-by: Mans Rullgard <mans@mansr.com>

SWS_CPU_CAPS are deprecated and slated to removed with libswscale major
version 3. No need to provide a SWS_CPU_CAPS_MMX2 as backward
compatibility define under the same explicit condition.

s->mb_x is reset to zero a couple of lines above. It does not make
sense to call ff_er_add_slice() with 0 as endx when the end of the
macroblock row was reached. Fixes unnecessary and counterproductive
error resilience in https://bugzilla.libav.org/show_bug.cgi?id=394.

Fixes a crash with zuffed files.

Use a different char* for extracting info string from the URL. The
other pointer can be made const then which elimates the need for a
cast and fixes the following warnings:
warning: to be safe all intermediate pointers in cast from ‘char **’ to
‘const char **’ must be ‘const’ qualified [-Wcast-qual]

Check the number of index tables before using byte offset based seeking
instead of the index_tables pointer.

This code spews a multitude of warnings with glibc (unchecked
return values), some of them possibly warranted.  Furthermore,
the deamonisation is not suitable for use with typical startup
scripts as it does not provide the PID of the daemon in any way.
Users wishing to run avserver as a daemon can still do so using
start-stop-daemon or equivalent tools.
