a5397dbaf1 Increase the resolution of default timebase
The old value 1000 was too low, which caused the effective duration and
frame rate calculation to have an 1% error for typical 30 frame/second
inputs. Symptom of the issue has been that most 2 pass encodings were
undershooting target bit rate by 1% or so for 30 fps input.

77e6b4504b vpxenc: require width and height for raw streams
Defaulting to 320x240 for raw streams is arbitrary and error-prone.
Instead, require that the width and height be set manually if they
can't be parsed from the input file.

c377bf0eec fix pipe support on windows
STDIO streams are opened in text mode by default on Windows. This patch
changes the stdin/stdout streams to be in binary mode if they are being
used for I/O from the vpxenc or vpxdec tools.

Fixes issue #216. Thanks to mw AT hesotech.de for the fix.

c4d7e5e67e Eliminate more warnings.
This eliminates a large set of warnings exposed by the Mozilla build
 system (Use of C++ comments in ISO C90 source, commas at the end of
 enum lists, a couple incomplete initializers, and signed/unsigned
 comparisons).
It also eliminates many (but not all) of the warnings expose by newer
 GCC versions and _FORTIFY_SOURCE (e.g., calling fread and fwrite
 without checking the return values).
There are a few spurious warnings left on my system:

../vp8/encoder/encodemb.c:274:9: warning: 'sz' may be used
 uninitialized in this function
gcc seems to be unable to figure out that the value shortcut doesn't
 change between the two if blocks that test it here.

../vp8/encoder/onyx_if.c:5314:5: warning: comparison of unsigned
 expression >= 0 is always true
../vp8/encoder/onyx_if.c:5319:5: warning: comparison of unsigned
 expression >= 0 is always true
This is true, so far as it goes, but it's comparing against an enum, and the C
 standard does not mandate that enums be unsigned, so the checks can't be
 removed.

3d84da6b8d Output the PSNR for the entire file.
If --psnr option is enabled vpxenc will output PSNR values for the
entire file. Added a \n before final output to make sure the output
is on its own line. Overall and Avg psnr matches the values written
to opsnr.stt file.

c7c0c05608 vpxenc: add unique track id
MKV requires a unique(ish) TrackID element in the track info header.
Instead of the current hard-coded ID, take a hash of the video track
and use that. This value is not written in the deterministic output
mode, despite being a deterministic value itself, to give flexibility
to change the hash algorithm and not affect bisecting across the
change.

75afcee962 vpxenc: add deterministic output option
By baking the version number into the output file, a hash of the file
will vary from commit to commit, even if the output is otherwise bit
exact. Add a -D option to suppress this behavior, for use when
bisecting or other debugging.

5329189a33 vpxenc: specify output file with -o
Requiring the output file to be specified with the -o option opens up
the possibility of supporting multiple input files in the future.

456bfb196b vpxenc: output webm by default
WebM should be preferred to IVF output, since it has wider tool support.

ea68ee0458 rename ivf{enc,dec} to vpx{enc,dec}
The new WebM output support should be preferred to IVF, but we can't
change the default behavior of the ivf* tools. There are a few other
default behaviors for these tools that are counterintuitive for
historical reasons, and changing the binary name provides the
opportunity to clean those up as well. This patch takes the first
step by renaming the binaries.
