Extract audio and resample example

[expd]

Hi,

Can you provide an example of how to use the resampler to downsample an audio stream and get access to the raw pcm audio data?

Hi, @expd. It's pretty easy, I'll writre it ASPA. The main thing is pretty the same you can find in trancode.go:

• Open input context
• Select AUDIO streams
• Open output codecs (e.g. pcm_s16le)
• Initialize Swr context
• Do converrtion
• Write output

Just wait a bit, and I'll write it.

I think some of the conversion functionality is missing
ffmpeg docs show that there's a different calculation for the number of samples required.
I'm trying to convert 48/stereo to 16/mono.
