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.
