This test uses the lavfi device and
is ready for more similar tests.

* qatar/master:
  lavf: don't guess r_frame_rate from either stream or codec timebase.
  avconv: set discard on input streams automatically.
  Fix parser not to clobber has_b_frames when extradata is set.
  lavf: don't set codec timebase in avformat_find_stream_info().
  avconv: saner output video timebase.
  rawdec: set timebase to 1/fps.
  avconv: refactor vsync code.
  FATE: remove a bunch of useless -vsync 0
  cdxl: bit line plane arrangement support
  cdxl: remove early check for bpp
  cdxl: set pix_fmt PAL8 only if palette is available

Fixes a failure in cdxl-pal8 test for the valgrind FATE instance.

Neither of those is guaranteed to be connected to framerate in any way
(if it even exists).

Fixes bug 56.

Because in contrast to the decoder, the parser does not setup low_delay.
The code in parse_nal_units would always end up setting has_b_frames
to "1", except when stream is explicitly marked as low delay.
Since the parser itself would create 'extradata', simply reopening
the parser would cause this.

This happens for instance in estimate_timings_from_pts(), which causes the
parser to be reopened on the same stream.

This fixes Libav #22 and FFmpeg (trac) #360

It's not supposed to be set outside of lavc.

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
cd1ad18a

No functional changes, just make it more readable.

No changes in the test results.

It is not allowed to change mid-stream like it does currently. Instead we need
to buffer the first 8 frames before returning them as a single packet, then
only return single frame packets after that.

Useful to return instead of -1 when the cause of the error is unknown,
typically from an external library.

it is already set in avcodec_alloc_frame()
