Could someone tell me how to create the mpds for the content. I am able to play the examples but when I create the mpd using MP4Box they don't seem to play in the player.

I tried using this as source
http://sourceforge.net/p/gpac/discussion/287547/thread/bb9a9893/?page=1

Basically I generated the mpd using

ffmpeg -an  -codec:v libx264 -profile;v baseline -level 13 -b:v 2000k output.mp4 -i elephants_dream_360p_24.y4m

I got the y4m from a standard source.

I created the mpd using

MP4Box -dash 10000 -dash-profile live -segment-name dream output.mp4

I don't have any errors on the console but the video doesn't play. It is just stuck.

I also tried DASHEncoder https://github.com/slederer/DASHEncoder

Nothing worked :(

I have

MP4Box - GPAC version 0.4.6-Dev-rev3744  required by DASHEncoder

I also tried the latest version of GPAC.

ffmpeg version git-2013-06-14-d891d35 built Jun 14 2013

If you have source files called video.mp4 and audio.mp4 then you can try

mp4box -dash 5000 -rap -no-frags-default -profile onDemand video.mp4 audio.mp4

if you have 3 video files at different bitrates video1.mp4, video2.mp4 and video3.mp4 and two audio files at different bitrates audio1.m4a and audio2.m4a, then you can try

mp4box -dash 5000 -rap -no-frags-default -profile onDemand video1.mp4 video2.mp4 video3.mp4 audio1.m4a audio2.m4a

If you have a muxed source called source.mp4 that contains audio and video then you can use

mp4box -dash 5000 -rap -no-frags-default -profile onDemand source.mp4#video source.mp4#audio

That works for me with v1.1.2 of dash.js and mp4box version 0.5.1-DEV-rev5208. See the --help of mp4box for additional commands to set the output mpd names, output folder etc. Pick a segment duration (5000 in this case) that is an integer multiple of your keyframe interval, assuming it is fixed.

Cheers

Will

Thanks Will,
I have multiple video in different size. if video in same size mp4box work
correctly, and if they in different size manifest not parsed correctly. I
wrote a script to change mpd file! I have tow mpd file. one for dash.js
and one for dash.as :)

Can you post the manifest produced by mp4box for videos of different sizes that does not get parsed correctly by dash.js? I have packaged multiple size videos with mp4box previously and they work fine with dash.js. Here is an example with video from 720p up to 2160p

dash.js get my first repesentation, find output mpd in attachment
I like to segmented my DASH, then I generate in this way:
after mp4box generate dhashed file I move this file in separated folder
then change mpd file for dash.as and make another version for dash.js

@mysamimi - your attachments did not come through the list server. Please post the mpd and segments on a web server and then provide the URL, or else list the mpd contents in the body of the email.

@mysamimi - the ondemand manifest looks valid. Can you provide more info when you say “that didn't work whit dash.js correctly!”. What exactly failed? Is there a failed network request , or trace statement from the console that explains why it didn’t play? The dash.js player rarely fails silently. With ondemand profile, the browser needs to make range requests via XHR which in turn requires specific CORS support. Are you sure that you have the correct CORS headers in your server to enable XHR to make range requests? The symptom if you don’t would be that the player would load the manifest just fine but then would fail when it tries to load either the init range or the index range.CORS is not required by Flash, which is why it may work in dash.as but not dash.js.

@wilaw DASH.JS detect only one Representation.
you can check it by http://5.144.131.116/test/web-3.mpd
and this is my manifest file that work grate http://5.144.131.116/test/3/web-3.js.mpd

If you run that mpd through the online validation tool at

http://dashif.org/conformance.html

it returns the following error log shown below. I suggest fixing the mpd before you try to play it in the player. Also, your mpd is a little strange - its has two adaption sets with only one video bitrate in each, then an adaption set with 4 video bitrates and then another with 3 video bitrates. All the video bitrates are different. Normally one would expect a single adaption set containing all the video represenations, assuming they represent the same content at different bitrates.

Created a new bug for the 1.4 release #429 that will create a central resource for how to generate good quality DASH content. Closing this issue for now.
