Anton Khirnov c98c1f434e matroskadec: don't set codec timebase. 
It's not supposed to be set outside of lavc.

Anton Khirnov d3e3ffa501 rmdec: don't set codec timebase. 
It's not supposed to be set outside of lavc.
Set r_frame_rate instead.

Anton Khirnov 741a05a293 avconv: compute next_pts from input packet duration when possible. 2011-11-30 07:47:43 +01:00
Anton Khirnov 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.

Aaron Colwell 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).

Vitor Sessak 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
not supporting SSE2.

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

Mans Rullgard d9ba767d61 musepack: fix signed shift overflow in mpc_read_packet()

There is further no need for a 64-bit intermediate here.

Cheng Sun 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.

Mans Rullgard 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.

Justin Ruggles 9d2dd356c2 adx: rename ff_adx_decode_header() to avpriv_adx_decode_header() 
It is used by the ADX decoder, and therefore needs to be exported in order to
work with shared libs.

Justin Ruggles 27360ccc5e adx: add an ADX parser. 
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.
