[FFmpeg-user] audio padding filter?

[Roger Pack]

Hello.
I was wondering if say I have an input that every so often "misses"
some audio input frames, is there any existing filter that would
basically add those frames in, as silence?
Or, said differently, is it "ok" for a file or input device to send
partial/broken audio input, or should the input device do all the
padding itself?
Are the audio codecs typically smart enough to accomodate for this
themselves, anybody know, or any implications there?
Thank you.
