Could also be useful for sending audio over the network to remote
speakers

I would also like something like this as I have a video scan
converted that adds delay too (perahps 1/4 second).

wrote this filter to fix the problem and slow down the video.
The basic idea is that the filter gets passed a size from the TV
Playback screen along the lines of "delay=10" which translates
into a
10 frame delay. The filter then creates a dynamic ring buffer
to hold
10 frames. Each time the filter is called the oldest frame is
returned.
Hi, I actually need something similar to this myself because I
have some serious DSP processing enabled which causes delays to
the audio signal
However, I was going to implement this simply in the audio
routines by changing the audio timestamp which is returned
(forget the call name). Just change this to be forwards or
backwards by the required amount and we should achieve the
desired result with very little code.
I would recommend that we try this before putting in the filters
method?
I was thinking along the same lines (on my todo list) with an OSD
option for increasing/decreasing the audio delay as every blue
moon I get a recording that lags in audio for a second or so
throughout the duration of the show.
