5db5169e46 avconv: multithreaded demuxing. 
When there are multiple input files, run demuxing for each input file in
a separate thread, so reading packets does not block.

This is useful for achieving low latency when reading from multiple
(possibly slow) input streams.

30f515091c h264: allow cropping to AVCodecContext.width/height 
Override the frame size from the SPS with AVCodecContext values
if the latter specify a size smaller by less than one macroblock.
This is required for correct cropping of MOV files from Canon cameras.

cac4760bf4 iac: generate codec tables as they are supposed to be 
Unlike its predecessor, Indeo Audio codec generates tables depending on
sampling rate. Previously decoder used pre-generated tables for 22050 Hz
which obviously doesn't work with other frequencies.

Many thanks to Maxim Poliakovsky for providing all needed information
for this.

e1a3fa5d3a indeo4: handle frame type 1 properly 
It turns out that this frame type is actually intra and should be used as
a reference for interframes too.

bc92214e27 vc1dsp: mark put/avg_vc1_mspel_mc() always_inline 
This ensures that these functions are inlined into the per-position
entry points, allowing constant propagation as needed for proper
optimisation.

d0e9415d23 fate: avoid freopen(NULL) in videogen/rotozoom 
A number of systems do not implement freopen() with a NULL filename
correctly.  This changes these programs to output individual images
if opening a named output argument as a file fails, in this case
assuming it is a directory.

67339f6eb4 avplay: use buffersrc instead of custom input filter. 
We do not allow user filters, so avtools shouldn't use them either.

b56825c40e mpc8: fix maximum bands handling 
In Musepack SV8 codec property tell the maximum nonzero band, but every
frame codes maximum band as a limit (i.e. strictly less than given value).
Synthesis also expects maximum nonzero band, so there's a need to convert
frame maximum band limit value.
