ext/ffmpeg/gstffmpegcodecmap.c: Add more specific width/height for DV video so that it negotiates more automatically.

Browse source 
Original commit message from CVS:
* ext/ffmpeg/gstffmpegcodecmap.c: (gst_ff_vid_caps_new),
(gst_ffmpeg_pixfmt_to_caps), (gst_ffmpeg_caps_with_codecid):
Add more specific width/height for DV video so that it negotiates more
automatically.
Try to avoid accessing NULL caps.
* ext/ffmpeg/gstffmpegenc.c: (gst_ffmpegenc_getcaps):
Add some more debuggin to the caps generation.
