I have downloaded the MPDs "http://dash.edgesuite.net/adobe/hdworld_dash/HDWorld.mpd" and all related .m4s files. I tried running it on VLC player. But the format is not recognized by VLC player.

I have downloaded this media segment using wget (1 to 14 segments are available) http://dash.edgesuite.net/adobe/hdworld_dash/hdworld_seg_hdworld_0696kbps_ffmpeg.mp4.video_temp2.m4s.

Can anybody tell me solution how to run .m4s format file on player?

System: Ubuntu 11.10

You need the initialization segment. It is often named "00" or "init" or doesn't have a sequence number like the other files, and often ends in ".mp4" rather than ".m4s". Then you just concatenate the files together. You can start anywhere in the sequence so long as you begin with the initialization segment.

For example

cat init.mp4 *.m4s > output.mp4

Then you have a playable mp4 file with content, assuming there is no encryption (DRM) applied to it.
