Janne Grunau 6a27ae28f9 mpegvideo: treat delayed pictures as used 
This requires to move the avcodec_default_free_buffers() call to
ff_MPV_common_end() since otherwise delayed pictures would get freed
during a size change.

Janne Grunau bd255f9feb lavc: set frame parameters after decoding only if necessary 
Direct rendering capable decoders call get_buffer() which will set the
frame parameters.

Prevents frames with wrong parameters when a decoder outputs delayed
frames after a resolution or pixel format change.

Justin Ruggles 14758e3211 lavr: temporarily store custom matrix in AVAudioResampleContext 
This allows AudioMix to be treated the same way as other conversion contexts
and removes the requirement to allocate it at the same time as the
AVAudioResampleContext.

The current matrix get/set functions are split between the public interface
and AudioMix private functions.

Mans Rullgard 02823f6d71 Make LOCAL_ALIGNED syntactically similar on all systems 
This changes the LOCAL_ALIGNED definition on systems where
DECLARE_ALIGNED is used so it matches the manual alignment
case, ensuring invalid use will not compile on x86 only to
fail on everything else.

Carl Eugen Hoyos 2ddf7c88d1 ZeroCodec: Flip output 
The initial testing of the VFW binary codec was flawed,

Re-testing using VirtualDub and various professional editing
applications has revealed it should have been flipped.

Martin Storsjö ccb59c106a rtpdec: Remove an outdated todo comment 
This comment was added in e309128f, in 2002, and has been brought
along since then more or less unmodified.

The first point of the todo was implemented in dbf30963 in 2006,
the second one is not relevant to rtpdec.c (brought along from
rtp.c in 8eb793c4 in 2008) but would be more relevant to the
rtp muxer, although it isn't a good idea anyway.
