<p>Hi Jiacheng,</p>
<p>Thanks for dropping a message. In MiniNDN, you can basically use
any headless NDN application you want. MiniNDN just starts the
application using a bash-command. But I think answering your
question becomes easier when knowing more details about what you
want to achieve. Publishing and retrieving large video files could
be interpreted in many ways.</p>
<p>If you simply want to handle those large video files as large
files, we have tools like ndncatchunks and ndnputchunks to
publish/consume files from the file system:
<a href="https://github.com/named-data/ndn-tools/tree/master/tools/chunks" target="_blank" rel="noreferrer">https://github.com/named-data/ndn-tools/tree/master/tools/chunks</a><br>
</p>
<p>When you want to emulate something like Dynamic Adaptive
Streaming over MiniNDN, it might be good to use something like a
DAS dataset that already has pre-computed video-segments (here's
one example dataset: <a href="https://dash.itec.aau.at/dash-dataset/" target="_blank" rel="noreferrer">https://dash.itec.aau.at/dash-dataset/</a>). To
retrieve these segments, you might use emulated video streaming
clients that retrieve the pre-computed segments based on some
adaption logic..<br>
</p>
<p>Junxiao did some recent work on video streaming. He has streaming
publishers and clients available for TypeScript. See here:
<a href="https://github.com/yoursunny/NDNts-video" target="_blank" rel="noreferrer">https://github.com/yoursunny/NDNts-video</a></p>
<p>Without having tried, but since those are TypeScript clients,
they should also work in MiniNDN. At least the producer should
run, and maybe Junxiao also has a headless consumer that can be
used with MiniNDN.</p>
<p>But as I said first, it really depends on what you want to do.<br>
</p>
<p>Best,<br>
Philipp<br>
