I am curious, does audio work with the DASHEncoder and latest VLC source? I am able to create the MDP files and M4S files. I am not able to get it to play. The video will play with no audio. Only the first segment will play. I get many errors regarding AAC decoding in the VLC debug logs:
VLC rejects the file and says that the format of my mpd file cannot be determined. The log contains the following:
How about providing a Windows executable so that people can try DASH without having to spend hours trying to figure out how to compile VLC? We want to see DASH in action!
I will make something like that at the beginning of January when I am back from the us but currently I do not have the time to generate a image that can be used out of the box or a installation guide.

It could be that DASH is disabled in VLC due to the fact that it is currently in an experimental state. So if you want to make sure that is enabled, you should check the Modules.am file in the streamfilter subdir and eventually change the line DIST_SUBDIRS=dash to SUBDIRS=dash. Sorry for that inconvenience but it is still in a beta state.
Note that nightlies may have bugs. If you have problems, pick another nightly.
