I would either need to ship it with 4 DV files (PAL std, PAL wide, NTSC std, NTSC wide) or add support for DV encoding from picture source, which is not trivial and offers little return value. Therefore, for something ad hoc like debugging I suggest: ffmpeg -loop_input -i some.jpeg -f s16le -i /dev/zero -target pal-dv - | dvgrab -stdin ... -- +-DRD-+ ------------------------------------------------------------------------------ This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword
