[samigo-team] Replacing Java applet with HTML5/Flash

[Keli Sato Amann]

Hi Sam,
Would you be willing to demo this on March 5th, which is the next scheduled SAMigo meeting? I can't speak for the whole team here at Stanford, but if the rest of the interested community is in agreement that this is comprable to the Java app in high-level ways, I can't see why we would need to branch this. We could do it sooner on Tuesday March26 instead, but it's a off week so people and possibly the conference room may already be booked. If you are willing, let me know date that is best (11 pacific 2 eastern). Would be nice if you could show in chrome first, then in Safari. 

I'm still unsure of why playback in the QuickTime player and in the popup window doesn't work for me--does it work for you? I have a MacBook Pro, if it matters. I thought at first that you were saying we'd be required to switch to them HTML5 audio player to enable this, but the QT player plays the au files from the Java recording app, so I wouldn't think that would be the case.

Regarding switching the player to HTML5 to remove QT dependency, that seems like a relatively easy thing to do, though I'm unclear of the advantages.  I've added this as SAM-2067 if you want to comment.

and I could get the audio to playback (though for some reason, I can't recreate it). I will put in a JIRA and talk to our dev team. And I'll talk to Ken and Christine, --not that we'd add something, but it needs to have similar behavior to java recorder. I do notes the recording window no longer closes after upload, did that get removed. 





Yeah, I removed the popup closing while I was doing more dev on it. The HTML5 recorder offers a timer, Flash fallback, attempt tracking, frequency display, and only changes a few files in Samigo. I believe Java on the desktop is dead. My recommendation would be to get a replacement intro trunk sooner than later, but if Stanford is committed to the Java applet, please let us know so I can get this work into a branch. 





So are you creating just a wav file, or are you creating an mp3 as well so this can play on IE without a plugin? And your flash version of the applet creates the same file type(s)? 





MP3 encoding is a patented process AFAIK. Maybe there is a Flash fallback to play the WAV in IE. if not, the Quicktime embed should continue to work with a little mime-type manipulation. 


The Flash version of the recorder creates the same raw, uncompressed audio. AFAIK, WAV and AU and AIFF are all the same thing (just different mime types). Any audio experts lurking?
