I also think that interpretations of iso packets should be left to the application. The 1394 driver should only address 1394 related issues, not application specific stuff such as reception of isochronous DV streams. DV is the most important usage for isochronous transfers today but we will most likely see a lot of new things in the future. The best thing to do, I think, is to keep the driver as clean as possible and conentrate on having it up to date with the development of 1394. Keep up the good work everyone! Regards, Anders Weitman |
