2092232581 lavf: estimate frame duration from r_frame_rate.
If r_frame_rate is set, it should be more reliable for this than either
codec or stream timebase.

39a7a5b8ab pthread: don't increment index on zero-sized packets.
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).

6b6ee58249 x86inc: Flag shufps as an floating-point instruction for the AVX emulation code.
Without this, code like "shufps m0, m1, m2, 0xaa" would not work in CPUs

0df5e869cb mpegaudio: do not use init_static_data() for initializing tables.
It is called once for each mpegaudio codec that is registered, which adds

3f5aa7dfa6 pthread: track thread existence in a separate variable.
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.

7c5ce99bd9 swscale: fix signed overflow in yuv2mono_X_c_template
As old bits are shifted out of the accumulator, they cause signed
overflows when they reach the end.  Making the variable unsigned fixes
this.
