MPEG Dash output does not pass MPD Validator

[FishB8]

Various errors when testing the MPD output on the validator.

I can provide more info... but I'm not sure where to start. All mpd output fails, but the validator only gives the first error it finds. If I manually fix and error another pops up, so there are multiple errors happening.

Suggestions welcome.

Actually I take that back, there only seems to one error. I messed up my copy/paste into the validator. I'll file a separate bug that is more specific.

You can reopen and edit this one instead, if it's still about mpeg dash output not validating

Ok.

To generate content for testing:

ffmpeg -y -f lavfi -i testsrc=size=1280x720:rate=30000/1001 -f lavfi -i sine=f=440:b=880:r=48000 -map 0:v -map 1:a -t 20 -c:v libx264 -b:v 1280k -g 30 -preset:v superfast -pix_fmt yuv420p -c:a libfdk_aac -ab 96k -ac 2 -f dash ./test.mpd

Running test.mpd through the validator produces the following:

Line:Col[12:93]:cvc-datatype-valid.1.2.1: ‘video’ is not a valid value for ‘integer’.
Line:Col[12:93]:cvc-attribute.3: The value ‘video’ of attribute ‘id’ on element ‘AdaptationSet’ is not valid with respect to its type, ‘unsignedInt’.
Unexpected error: For input string: "video"

The same applies for 'audio' on an AdaptationSet element following it.

Of course there is always a possibility the validator is incorrect, but I'm assuming it is authoritative since it is provided by the standards group.

I just now noticed that the validator is based off the 2012 standard, so it may not be up-to-date with the newer 2014 standard. Don't know enough about it yet to know what the differences are.

A patch is on the mailing list.

I'm doing MPEG-DASH live streaming, and the generated mpd file is not valid when testing with the mentioned mpd validator.

The error:
Line:Col[12:150]:cvc-complex-type.3.2.2: Attribute ‘publishTime’ is not allowed to appear in element ‘MPD’.

I'm using the static windows build git-91b668a (2015-09-23), but had this error also with earlier builds.

The generated MPD file looks like this: ​http://pastebin.com/xf0kNREr
