[linux-audio-dev] some more GMPI thoughts

by "horsh

1)is API monolithous or there are sub-APIs like GMPI-audio, GMPI-seq, GMPI-control 2) Explicit versioning for API? 3) Explicit versioning for plugins? 4) uniq IDs for plugins? who is authority? 5) format for plugin state saving: XML? (damn its ugly!) I vote for more YAML-like language. 6) Should the GMPI discussion produce reference plugin implementation reference host implementation reference tools implementation 7) Can there be off-line non real-time plugins? 8) Should the specification produce any requirement for more documents? For example: A documant describing standard set of plugins (like in General Midi) so one could expect the first 64 plugins to be so and so. horsh

Re: [linux-audio-dev] GMPI - requirements

by "horsh

Well it's just requirements? Then what about : 1) jack-transport-like and 2) LADCCA-like functionality? the requirement resolution could sound as: "GMPI does not need such functionality", but if it souns as "GMPI _does_ need..." then it would be very welcome. horsh ====================8<========================== One of my tasks as part of GMPI is to provide a draft of the requirements doc. I turn tp you all. If you have requirements that you think should be in GMPI - please let me know. These have to be requirements. Not handwaving though explosions, and not wishful dreaming. Things that are required or desired that will make GMPI be the open music platform we need. Feel free to email me privately or publicly. I'll be happy to condense ideas and to extract requirements from whatever you have for me. Trying to get the ball rolling again... Tim

[linux-audio-dev] GMPI - requirements

by Tim Hockin

One of my tasks as part of GMPI is to provide a draft of the requirements doc. I turn tp you all. If you have requirements that you think should be in GMPI - please let me know. These have to be requirements. Not handwaving though explosions, and not wishful dreaming. Things that are required or desired that will make GMPI be the open music platform we need. Feel free to email me privately or publicly. I'll be happy to condense ideas and to extract requirements from whatever you have for me. Trying to get the ball rolling again... Tim -- Notice that as computers are becoming easier and easier to use, suddenly there's a big market for "Dummies" books. Cause and effect, or merely an ironic juxtaposition of unrelated facts?

[linux-audio-dev] Performance utilities of the future.

by Robert Jonsson

Hi, This seems like an interesting article, describeing a new kernel service/application in 2.6. http://www-106.ibm.com/developerworks/library/l-oprof.html?ca=dnt-441 It's called OProfiler. "OProfile can help you identify issues such as loop unrolling, poor cache utilization, inefficient type conversion and redundant operations, branch mispredictions, and so on." Just thought I'd pass it on. /Robert

[linux-audio-dev] jack: what does this mean ?

by Sascha Retzki

Hi. Well, you know I am a novice in everything related to linux & audio ;), but THIS: jackd: pcm.c:5959: snd_pcm_mmap_begin: Assertion `pcm && areas && offset && frames' failed. received signal 6 during shutdown (ignored) is an alsa-error, right ? I could not find an answer on the question what it means, so maybe some of you can ... greez, Sascha Retzki _____________________________________________________________ Linux.Net -->Open Source to everyone Powered by Linare Corporation http://www.linare.com/
