d8b06521a9 avconv: check for an incompatible changing channel layout 
The decoder can change the layout and channel count during decoding,
but currently we only validate that the two are compatible when opening
the codec. This checks for incompatibilities after each decoded frame.

6208313aeb avio: make AVIOContext.av_class pointer to const 
Fix this warning:
libavformat/aviobuf.c:663:20: warning: assignment discards qualifiers from pointer target type

Although this is a public header, it should remain source and
binary compatible.

3c58300269 matroska: do not set invalid default duration if frame rate is zero 
If a video track specifies a zero frame rate (invalid but occurs),
this results in a division by zero and subsequent undefined conversion
to integer.  Setting the default duration from the frame rate only
if the latter is greater than zero avoids such problems.

ac97d47d9b mkv: use av_reduce instead of av_d2q for framerate estimation

204bcdf56c mkv: report average framerate as minimal as well 
This is in line with other demuxers and overall seems more correct
than assuming codec time base.

0f96f0d996 aacenc: Fix issues with huge values of bit_rate. 
Do not pointlessly call ff_alloc_packet multiple times,
and fix an infinite loop by clamping the maximum
number of bits to target in the algorithm that does
not use lambda.
