DDC VDIF Change Log:

1.5.014. Changes made:
  • Attenuation commands will now execute immediately instead of at the beginning of the next second. A new attenuation command can be sent once per 20ms.
  • Monitors from the RDBE synthesizer board will now be read once per 100us instead of once per second.
  • The phenomenon of increasing delay with decreasing BW has been corrected (a.k.a "bandwidth dependent delay change bug").
  • Additional preparatory work to fix the missing last frame issue when a recording is stopped.
