[FFmpeg-user] Basic dash muxing

[Jesús Aguilar Armijo]

I see, thank you. I am doing now from a .yuv video and the HLS 
segmentation works perfectly but I still have problems with dash. There 
is no error in the execution but I get less output files than expected 
so I did some mistake with the command options.

For: ffmpeg -s:v 1920x1080 -r 25 -i inputVideo.yuv -c:a aac -c:v libx265 
-f dash –seg_duration 2 out.mpd
The outputs are: init-stream0.m4s, chunk-stream0-00001.m4s, 
chunk-stream0-00002.m4s, out.mpd

The video is 20 seconds, for 2 second segments it should be 10 segment 
files at least (Plus mpd). I don't know what I am doing wrong.

Thank you for your help, best regards.
