I had already scheduled another way to implement that feautures:
- IDirectFBVideoProvider::SetSpeed( double multiplier )
Specify a frame rate multiplier (1.0 normal speed);
- IDirectFBVideoProvider::GetSpeed( double *multiplier )
Get the current frame rate multiplier;
- IDirectFBVideoProvider::SetPlaybackFlags( DFBVideoProviderPlaybackFlags )
DFBVideoProviderPlaybackFlags:
DVPLAY_NORMAL = normal playback,
DVPLAY_REWIND = reverse playback,
DVPLAY_LOOPING = restart playback at the end (gapless)
Specify advanced playback flags.
The method suggested by Daniel has some incoveniences:
- The speed multiplier is costrained by the defined TrickMode speeds
and the video provider has to check that values one by one.
- DVTRICKMODE_FF with speed set to DVTRICKMODE_1 is exactly equal to
DVTRICKMODE_NONE.
- The prefix DVTRICKMODE_ is used by different enums, this is a bit
confusing.
- DVTRICKMODE_FF doesn't specify a real fast forwad, because *fast*
depends on the speed mode.
- Forward is the normal direction of the playback.
- DVSTATE_FF and DVSTATE_RW doesn't specify a new video provider state
but only the direction of the playback (i.e. the current state should
be DVSTATE_PLAY).
If it won't cause too much inconveniences, I will apply the previously
scheduled
changes.
