DV works too. Cool!
Below is a patch for codecs.conf which corrects "Sony Digital Video" codec entry and adds
"MainConcept DV Codec" -- a little faster (uploaded to incoming/dv"). Both work with AVI
and MOV DV.
Some remarks to MOV support:
- Is there an aspect ratio info in MOV files? If not, maybe set default to 4:3 for all DV.
Excerpt from Adobe Premiere FAQ:
"DV clips have image dimensions of 720 x 480 pixels for NTSC and 720 x 576 for PAL. In
addition, these dimensions can come as either a 4:3 or a 16:9 aspect ratio, depending on
the camera settings at the time the footage was taken."
- It seems that mplayer scans the whole MOV before it starts playing. DV files size is
usually in the order of GigaBytes, so it takes long to start playing.
Another excerpt from AP FAQ:
"Does Adobe Premiere 5.1 support .dv file format? Yes. By supporting QuickTime 4.0's
architecture, Adobe Premiere 5.1 now has direct support for .dv files. Using QuickTime,
Premiere can playback DV files even when a DV codec is not present in the machine."
Maybe this "QuickTime 4.0's architecture" would be useful for MPlayer and sorenson codec.
