This requires using a separate init function, since there
isn't necessarily any fmtp lines for this codec, so
parse_sdp_a_line won't be called. Incorporating it with the
alloc function wouldn't do either, since it is called before
the full rtpmap line is parsed (where the sample rate is
extracted).

I.e. on streamcopy set output codec timebase from input stream timebase
(as opposed to input codec timebase). This should be more sane, because
since the stream is not decoded, the input codec tb has no relation to
the timestamps of the copied packets.

It's not supposed to be set outside of lavc.

It's not supposed to be set outside of lavc.
Set r_frame_rate instead.

If r_frame_rate is set, it should be more reliable for this than either
codec or stream timebase.

This was broken in 2a651b71.

Also fix reporting of the number of samples added/dropped.

The next call to decode() will update from an invalid index, which will
either lead to a memcpy() where dest==src (2 threads), or lead to a
crash (>2 threads).

Document it a little and possibly fix a bug in dxva2_vc1.

Use the @command{} tag when needed and cleanup the examples.

This fixes a crash on a corrupt bitstream (bugzilla #93).

Without this, code like "shufps m0, m1, m2, 0xaa" would not work in CPUs
not supporting SSE2.

It is called once for each mpegaudio codec that is registered, which adds
significant overhead.

Using an unsigned variable avoids problems with overflows.
There is further no need for a 64-bit intermediate here.

Interlaced videos can contain progressive frames too and now wrong scantable

This fixes a compile error on mingw32 when using p->thread
directly (as if it were a pointer) to track thread existence,
because the type is opaque and may be a non-pointer.

As old bits are shifted out of the accumulator, they cause signed
overflows when they reach the end.  Making the variable unsigned fixes
this.

The way these values are used, they should have an unsigned type.

altivec.h is no longer (indirectly) included, so this hack is not

It is used by the ADX decoder, and therefore needs to be exported in order to
work with shared libs.

This simplifies the decoder so it doesn't have to process an in-packet header
or handle arbitrary-sized packets. It also fixes decoding of files with large
headers.
