f6765f3f04 Extend DV autodetection to also reliably detect single-frame DVs with 
a higher score that MAX/4.
It checks that there are at least 10 DIF headers and at least one per
24000 bytes, and if so considers the file reliably detected as DV.
Passes probetest, too.

6377de611a Try harder to avoid false positives for DV probe. 
Require at least one signature match per provided 1MB of probe data,
and if there is only a single match, return at most MAX/4.
Fixes issue1382 but could/should probably still be improved.

96319c3922 * let DV muxer generate audioless DV streams. This might not be 100% 
complaint with the SMPTE & IEC specs, but it seems harmless enough.
     The way we "specify" that there's no audio is by simply leaving
     audio DIFs filled with 0xff (I bet there's a way to mark this
     properly in the system info section!).

118e91f3d8 * Phase 1 for DV encoding support. Muxing/demuxing of DV streams is now 
possible. For example you can do:

          ffmpeg -i i.dv -i audio_track.mp3 -map 0.0 -map 1.0 \
	         -vcodec copy -acodec pcm_s16le out.dv

   * Preparations for getting rid of DVAUDIO codec, DV stream really
     contains PCM audio, so there's no codec needed if we have a
     decent demuxer.

   * Providing entry points for dv1394 write support.
