[FFmpeg-user] MPEG DASH with Audio Only Adaptive Streaming

I figured out how to do this. The problem was just that I forgot to put the -map 0:0 -map 1:0, etc. arguments in these commands. So ffmpeg was only selecting the first stream in the input.

Hi all,
I'd like to generate an MPEG DASH stream that would include all of the Representations/AdaptationSets inside of my mp4. I've mapped 5 separate audio streams into my input mp4.
However, no matter what I do with the command line arguments, I'm always only getting one Adaptation Set.

ffmpeg -i output.mp4 -codec copy -f dash -single_file_name output.m4s -seg_duration 9.75238095238095 -adaptation_sets "id=0,streams=a" -hls_playlist 1 output.mpd
But it doesn't seem to generate an MPEG DASH stream for all input streams either.
What is the correct command line I should be using for this? If this doesn't work, I'll file an issue to ffmpeg for this, and try to figure out how to fix this.
Thanks,
Ronak
