ffmpeg - what is recommended to use with Mpeg-dash, VBR or CBR? -
i need trans code videos use them mpeg-dash, bitrate, shroud use variable bitrate (vbr) or constant bitrate (cbr).
which of them work better mpeg-dash?
both have advantages , disadvantages. since mpeg-dash
can used adaptive streaming having cbr
can improve playback because vbr
can temporarily go on bitrate threshold , trigger stream switch if average bitrate within limits.
with cbr
easier calculate bandwidth use etc. since constant.
the problem cbr
can degrade quality more complex scenes. best compromise use called constrained vbr
, vbr
constrained maximum 110% of nominal data rate.
