6a27ae28f9 mpegvideo: treat delayed pictures as used
This requires to move the avcodec_default_free_buffers() call to

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.

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.

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.

ccb59c106a rtpdec: Remove an outdated todo comment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.
