    <p>I've built a little app engine app that lets users upload short recordings. Some of the recordings are done in-browser with <a href="https://github.com/mattdiamond/Recorderjs" rel="nofollow noreferrer">https://github.com/mattdiamond/Recorderjs</a>, which creates wav files. To save space, I'd like to convert those to ogg before writing them to the app engine datastore, so that I use less of my outgoing bandwidth when I play the audio recordings back to users.</p> <p>How can I do this? I googled around, and apparently there's a command line tool called oggenc that encodes to ogg -- but I'm pretty sure I can't install that (or, even if I could install it, make calls to it) on app engine.</p> <p>I found a similar question at <a href="https://stackoverflow.com/questions/16821919/encode-audio-from-getusermedia-to-a-ogg-in-javascript">Encode audio from getUserMedia() to a .OGG in JavaScript</a> -- this links to <a href="https://github.com/jpemartins/speex.js" rel="nofollow noreferrer">https://github.com/jpemartins/speex.js</a>, a project that looks like it might eventually be able to convert from wav to ogg in javascript (which would be great), but, as far as I can tell, does not do so at the moment. At <a href="https://github.com/jpemartins/speex.js/issues/4" rel="nofollow noreferrer">https://github.com/jpemartins/speex.js/issues/4</a> the authors mentions that WAV -> ... -> OGG is not yet possible.</p> <p>What else should I try?</p> <p>Edit: My app engine code is written in Python, so another possibility would be to do the conversion there, with a python module that can convert wav to ogg. I think <a href="http://pymedia.org/" rel="nofollow noreferrer">http://pymedia.org/</a> can do this, but I'd have to somehow install it on app engine -- is that possible?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
