[linux-audio-dev] LADSPA BOF LA2004 report

This is a quick report back from the LADSPA bird-of-a-feather session that happened on Friday morning at the LA Conference. Attendees of the session can expand on any details that aren't clear here once they recover :) The atendees signed off on the text that has unanimous agreement, but not on the open question IIRC. Date 2004-04-30 10:00 Duration 3:30 Present 11 people (dont have a list of names, sorry) Users 10 Plugin devels 3 Host devels 6 Unanimous agreement was reached on a number of pointsdditions, these are: Momentary hint: additional hint (requires toggle) - indicates that control (UI) shouldn't latch the control. Port paths: '/' should be used as a port path component divider. No leading slash will be used. This is for grouping related controls in UIs and to allow more natural reflection of LADSPA port names into OSC or HTTP, for example. Zero pointer buffer values: if hint bit is set then the buffer pointer can be NULL to indicate that the port is not connected. There will be a LADSPA 2.0 which will differ from the 1.0 series only in enforcing all metadata to be represented externally. No features over what was agreed here will be added. Design work will start as soon as the conference finishes. Estimates for time to completion are on the order of 2 months. Open Questions There is the possibility of an interrim 1.2 ladspa.h version that will add the momentary hint, port paths, zero pointer buffer values and port name extension enumerations, and will be deprecated by 2.0. It was decided to leave it to the LADSPA devleoper community to vote if this was desirable, as there was no consensus. - Steve
