问题
I use AWS Elastic Encoder to encode to HLS (with success), and have been trying to get the same mp4 files transcoded to play in MPEG-Dash.
When I transcode into HLS, I typically choose 30 sec segments, and for a 5 min video, I get 12 files and a playlist (using one of the built in presets)
When I transcode same file into MPEG-Dash (using 30 second segments) - I still get one large file. No segments. And no audio. The playlist format seems to be ok - in .mpd format. I am using a built in preset.
Am I supposed to do TWO transcodes for every mpeg-dash transcode? One in video, and the other in audio, with a playlist to tie the two together?
Is there an online tutorial which outlines how to encode into MPEG-Dash format?
Or what do most of you use?
