Is there any plan to create FESTIVE controller?

I am trying to use my own mpd with your TAPAS Player. When using your suggested MPD things work fine, but I receive the following Errors:

Looking at both MPD files I see the following for any one representation:

<SegmentTemplate duration="2000" initialization="$RepresentationID$/init.mp4" media="$RepresentationID$/$Number$.m4s" startNumber="1" timescale="1000"/>
<Representation bandwidth="1018420" codecs="avc1.4D401F" frameRate="24" height="480" id="V4" scanType="progressive" mimeType="video/mp4" width="1128"/>

<Representation bandwidth="869460" codecs="avc1.4d401e" height="480" id="3" mimeType="video/mp4" width="854">
        <BaseURL>car-20120827-87.mp4</BaseURL>
        <SegmentBase indexRange="708-1183">
          <Initialization range="0-707" />
        </SegmentBase>
      </Representation>

Does your player only accept this one certain form of encoding?

besides PANDA, is there any plan to create other algorithms? such Miller's http://www.tkn.tu-berlin.de/fileadmin/fg112/Papers/Adaptation_Algorithm_for_Adaptive_Streaming_over_HTTP.pdf?

This is for the paper
Chenghao Liu, Imed Bouazizi, Miska M. Hannuksela, and Moncef Gabbouj. Rate adaptation for dynamic adaptive streaming over HTTP in content distribution network. Signal Processing: Image Communication, 27(4):288–311, April 2012.

Is there a way to save the streamed video into a file? Something like "v_sink = 'filesink location=video.mp4'"? I want to play the video with an other player because I have problems with the TAPAS "player".

For example:
python play.py -u http://www-itec.uni-klu.ac.at/ftp/datasets/DASHDataset2014/BigBuckBunny/2sec/BigBuckBunny_2s_onDemand_2014_05_09.mpd

When the player wants to make a switch at the second 4 the screen turns gray and you can appreciate something like "miscoded fragments" of the original video but there is something wrong. I don't know how explain this better with only words.

For the youtube dataset everything works fine, but the content that I have generated works like the itec.uni-klu dataset.

Thanks in advance.

No video output even with explicit -m gst option selected. IIRC video output played smoothly a few months earlier on a similar machine.
