Actually, I use custom IO in my own application to prefetch data via HTTP.
I'm trying to calculate duration from bytes with bit_rate, for:
1. Calculate necessary download speed.
2. Adjust prefetch buffer size.
3. Show prefetched duration in progress bar.
I thought AVFormatContext.bit_rate is a convenient alias.
Is AVCodecContext.bit_rate more suitable for these purpose?
