Michael Niedermayer 4abc411b97 nutenc: choose for non audio streams a timebase with finer resolution.
While a 25 fps stream can in general store frame durations in 1/25
units, this is not true for the timestamps. For example a 25fps
and a 25000/1001 fps stream when they are stored together might have
a matching 0 timestamp point but when for example a chapter from
this is cut the new start is no longer aligned. The issue gets
MUCH worse when the streams are lower fps, like 1 or 2 fps.

This commit thus makes the muxer choose a multiple of the
framerate as timebase that is at least about 20 micro seconds precise

Michael Niedermayer e3fb5bc147 nut: store and read the r_frame_rate
With this, when we use a finer timebase than neccessary to store
durations the demuxer still knows what the original timebase was.

Mans Rullgard 05238927b7 fate: make lavfi tests output only md5
Instead of saving huge raw files, use the md5: output pseudo-protocol
to calculate the checksum of the file directly.  This is especially
useful when testing on remote targets as it avoids transferring 3.6GB
over the network.

Stefano Sabatini c014631461 Update lavfitest reference after commit:
Author: bcoudurier
   Date:   Sat Jul 3 03:11:04 2010 +0000

       Set graph swscale opts before parsing it, that way opts are available
       when auto-adding scalers.

It changed the swscale flags used by the auto-added scalers, and so
the output video.

Stefano Sabatini cec96e8de3 Add some ad-hoc tests for libavfilter.
A patched version of ffmpeg supporting video filters is required for
getting this working; thus make lavfitest is supposed to work only in
the libavfilter repository for now.
