dphov / dash-avc264 command lines

Created September 22, 2017 09:15 — forked from ddennedy/dash-avc264 command lines

Use ffmpeg and mp4box to prepare DASH-AVC/264 v1.0 VoD

	See my DASH-IF presentation from October, 2014:
	https://s3.amazonaws.com/misc.meltymedia/dash-if-reveal/index.html#/

	1. encode multiple bitrates with keyframe alignment:
	ffmpeg -i ~/Movies/5D2_Portrait.MOV -s 1280x720 -c:v libx264 -b:v 1450k -bf 2 \
	-g 90 -sc_threshold 0 -c:a aac -strict experimental -b:a 96k -ar 32000 out.mp4

	My input was 30 fps = 3000 ms. If it were 29.97, then a GOP size of 90 frames will yield a base segment
	size of 3003 milliseconds. You can make the segment size some multiple of this, e.g.: 6006, 9009, 12012.
