Adding an audio delay in the encoder section

[gavin2812]

Hello all,

Is it possible to add a delay to the audio-only part of this encoder section?

enc = %ffmpeg(format = "flv",
       %audio(codec="libfdk_aac",
        samplerate=44100,
        channels=2,
        b="320k",
        profile="aac_he"),
       %video(codec = "libx264" , width = 1920, height = 1080, b = "2500k", g = 50, preset = "veryfast")
                                )
output.url(fallible=true, url=url1, enc, input)

The input is from an input.rtmp live stream.

I'm not sure if this is possible, if yes, how/where should I insert the delay (or maybe buffer) part?

Thanks in advance.
