Assume Sample Rate

( Diese Seite in Deutsch )

AssumeSampleRate(clip clip, samplerate int)

AssumeSampleRate (exists starting from v2.07) changes the sample rate (playback speed) of the current sample. If used alone, it will cause desync with the video.

Examples:

# Let's play that this video is 25fps, 44100hz video clip.
AviSource("video_audio.avi")

# Play audio at half speed:
AssumeSampleRate(22050) 

# Play video at half speed:
AssumeFPS(12.5)

# Video and audio is now in sync, and plays in slow-motion.
