<div class="moz-cite-prefix">Hi Yunhui Fu,<br>
<br>
sounds nice I would be curious to see the code ;). MPEG is
currently specifying DASH 2nd Edition including a corrigendum and
updates which is now FDIS and will be ready soon. The updates are
already part of the reference software and available under [1] so
you should probably also consider these changes and include them
into your software.<br>

<div>The DASH (Dynamic Adaptive Streaming over HTTP) module of
the VLC is base on a draft DASH spec and now it is outdated.
We recently updated the DASH module to support the latest
spec(ISO/IEC 23009-1 2012) for our academic study purpose.
It's base on the GIT version and it now works for some
existing DASH test media content in the Internet.<br>
<br>
</div>
<div>Since we use it to study the network flow pattern and are
not expert on the media encode/decode algorithms, we met
some problems in implementing the protocol and have no clue
to fix it.<br>
<br>
</div>
<div>1. The original DASH and other similar modules, such as
HTTP Live, smooth, were implemented as ''stream_filter'' in
the directory modules/stream_filter, our updated module is
also implemented as a 'stream_filter' module. we also
noticed that the other protocols, such as asf, were
implemented as a 'demux' module. What's the best
implementation method? stream_filter or demux?<br>
</div>
<div><br>
</div>
2. One of issues in our implementation, there's black screen
at the switching of the video resolution from low res to high
res, we don't know if it's the problem of the encoder. The
content is encoded by Squeeze 9(<a moz-do-not-send="true"
href="http://www.sorensonmedia.com/video-encoding">http://www.sorensonmedia.com/video-encoding</a>).
If it is the problem of the encoder, how can we encode the
media content and split it to multiple segments? for example,
we use fmepg and MP4Box to encode the content (Big Buck Bunny
<a moz-do-not-send="true" href="http://www.bigbuckbunny.org/">www.bigbuckbunny.org/</a>),
what's the recommend arguments for the tools.<br>
<br>
</div>
<div>3. The vlc refuse to work if we feed it with the audio and
video segments alternatively. Can vlc work in such manner?<br>
<br>
</div>
<div>4. Is it possible to merge all of the three modules,
live/smooth/dash, into one single module? Since they use
similar protocols.<br>
</div>
<div><br>
</div>
<div>Thank you in advanced for the help. We eager to release the
source to the community once the above issues fixed.<br>
