[libdv-dev] Where to go ?

[Stefan L. <Ste...@sn...>]

Hi,

what about the future of libdv ?

During the last months Buck is the only one of the original developers
who takes care of libdv.

- output format selection
  Our sample applicatiopn should take care of
  - direct output (X11) only if desired.
  - possible intermix of PAL/NTSC
  -> select output buffers in a way that at least two frames could
     be placed in.
- audio extraction
- sample application
- tests cases
- encoding (dct88 vs. dct 248)
  When to use dct248 insteadof dct 88
  From my experience 248 is used when there are significant differences
  in Y values within a macro block (segement)
  Upper left <-> lower right.
  So for encoding we need a function like
	dv_enc_use_dct248 (dv_macroblock_t *mb)

- new functions:
	typedef enum { normal, wide} dv_format_t;

	int		dv_enc_use_dct248 (dv_macroblock_t *mb)
	int		dv_dec_is_wide_screen (dv_frame_t *fr)

	dv_format_t	dv_notify_format_change (void);
	dv_system_t	dv_notify_system_change (void);
