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!).

0c9fc6e187 * replacing calls to not-always-available gmtime_r with our own code. 
The new helper function actually differs in semantics from gmtime_r,
     so if that seems to be a problem I can actually move it to dv.c
     completely, since only DV muxer uses the code anyway.

      ideas. Please don't hesitate to give it a spin:

7458ccbb02 * DV handling was streamlined for both muxing/demuxing and 
decoding. All muxing/demuxing functionality is now available
     in libavformat/dv.[ch].

   * dv1394.c and avidec.c were hooked up with general DV demuxer.

   * DVAUDIO is dead! Long live pcm_s16le!

   * DV audio is now always recognized -- which means we can
     now hear all those ducks quaking in pond.dv.

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.
