I don't understand the meaning of keyint and vbitrate in a DV context. It doesn't make sense. > -oac copy keep in mind, that piave presently can only write interleaved DV audio. so, even if it is already possible to play a DV video stream and play the AVI-audio-track or read/play any ogg/wav file parallel to rawDV/AVI video, it is neither possible to save this audio to raw DV nor AVI. Anybody care to work on the libsamplerate plugin which is already started? This would be a nice project to get started with piave. All iostream plugins (DV/ogg/wav/AVI) produce raw PCM audio for internal processing. This needs (most likely) to be resampled and then written into the AVI-file (or interleaved into the raw DV stream). Should not be very difficult. Mixing audio is also trivial, so this is basically all we need to be able to be able to underlay video with music (or any audio). Eh?

It is _exactly_ : - PAL 144000*25*8 bps - NTSC 120000*29.97*8 bps > What audio codec ordinary does DV use? PCM (my cam 32-48 kHz) Cheers, Rolf -- contacts: www.physi.uni-heidelberg.de/~dubitzky
