[FFmpeg-devel] [PATCH v2] avformat/smoothstreamingenc:add bitrate calculate

[Jun Li]

Thanks Carl for review.
Smooth is not the only one need bitrate for manifest, Dash also need this
value for "Bandwidth" field:
https://github.com/FFmpeg/FFmpeg/blob/master/libavformat/dashenc.c#L730
Although there is some difference, both the calculation are based on
fragment size, which is the result after muxing. So it might be very hard
to do it outside of Muxer.

Thanks. Regards
