Hi,
I develop a AVStreaming driver for a sound card with a latency of 3
seconds. I want to report the current "Play" position to the audio player.
I have implemented the properties:
KSPROPERTY_AUDIO_LATENCY
KSPROPERTY_AUDIO_POSITION
KSPROPERTY_AUDIO_LATENCY is never requested, KSPROPERTY_AUDIO_POSITION
is periodically requested by the contents does not have an influence to
the position bare of the player or to the behavior on the end of a song.
Does anybody know which requests must be implemented to handle a sound
card with a large latency correctly.
Thanks
Guenter
