832ba44d8d avconv: saner output video timebase.
r_frame_rate should in theory have something to do with input framerate,
but in practice it is often made up from thin air by lavf. So unless we
are targeting a constant output framerate, it's better to just use input
stream timebase.

Brings back dropped frames in nuv and cscd tests introduced in

cd1ad18a65 rawenc: switch to encode2().
This changes a number of FATE results, since before this commit, the
timestamps in all tests using rawenc were made up by lavf.

In most cases, the previous timestamps were completely bogus.

In some other cases -- raw formats, mostly h264 -- the new timestamps
are bogus as well. The only difference is that timestamps invented by
the muxer are replaced by timestamps invented by the demuxer.

cscd     -- avconv sets output codec timebase from r_frame_rate
and r_frame_rate is in this case some guessed number 31.42 (377/12),
which is not accurate enough to represent all timestamps. This results
in some frames having duplicate pts. Therefore, vsync 0 needs to be
changed to vsync 2 and avconv drops two frames. A proper fix in the
future would be to set output timebase to something saner in avconv.

nuv      -- previous timestamps for video were wrong AND the cscd
comment applies, one frame is dropped.

vp8-signbias -- the file contains two frames with identical timestamps,
so -vsync 0 needs to be removed/changed to -vsync 2 and avconv drops one
frame.

vc1-ism -- apparrently either the demuxer lies about timestamps or the
file is broken, since dts == pts on all packets, but reordering clearly
takes place.

d2afbd9a56 frame{crc/md5}: set the stream timebase from codec timebase.
Right now those muxers use the default timebase in all cases(1/90000).

This patch avoid unnecessary rescaling and makes the printed timestamps
more readable.

Also, extend the printed information to include the timebases and packet
pts/duration and align the columns.

Obviously changes the results of all fate tests which use those two
muxers.

7c152a458d lavf: inspect more frames for fps when container time base is coarse
As per issue2629, most 23.976fps matroska H.264 files are incorrectly
detected as 24fps, as the matroska timestamps usually have only
millisecond precision.

Fix that by doubling the amount of timestamps inspected for frame rate
for streams that have coarse time base. This also fixes 29.970 detection
in matroska.

2fad097788 Add FATE tests
This adds a "fate" make target which runs the full FATE test suite.
Individual tests can be run with "make fate-$testname".

The location of the FATE test samples must be specified with the
--samples=PATH option to configure.

The tests/fate-update.sh script regenerates the references files and
test list from the online FATE database.  These are checked in since
generating them requires non-standard tools.
