[libdv-dev] Proposal for quality setting

[James B. <ja...@ex...>]

All,

To get real-time performance on slower machines, we could have a global
quality control.  It could be a bitfield, something like:

#define DV_QUALITY_BEST       ~0
#define DV_QUALITY_FASTEST     0     /* Monochrome, DC coeffs only */
#define DV_QUALITY_COLOR       1     /* Clear this bit for go to
monochrome */
#define DV_QUALITY_AC1         2     /* Clear to avoid any AC coeffs  */
#define DV_QUALITY_AC2         4     /* Clear to avoid second phase AC
coeffs */

Curently, only the main decode loop and dv_parse_video_segment() would
need to know about quality.
