I'd like to use OGG@64kbps as an output format (for low data consumption). I'm currently writing an audio streaming client, and I need the estimated data size before streaming. It would be great if the prediction could be accurate to within a few kB. Is it possible to set up ffmpeg or SoX to encode into Ogg/CBR so I can calculate the exact data size?
I agree VBR would be the better option where quality is concerned, but VBR 64kbps doesn't mean that I actually get 64kbps in average. Sadly...
Or would ABR be an option?
