File (Entry) to Src

[Si Robertson]

Hi,

I apologize in advanced if this is a dumb question but it has me stumped at the moment. After a user has chosen an audio file from their local file system (chrome.fileSystem.chooseEntry) how do I convert the file path to a value that can be used as the src attribute value of an audio element?

It would be foolish to load an entire audio file into memory and convert it to an object URL (which could be used as a src value) so there must be something I'm overlooking in the Chrome Apps API.

Thanks.

The callback of chrome.fileSystem.chooseEntry receives an Entry object (http://dev.w3.org/2009/dap/file-system/file-dir-sys.html#the-entry-interface). This object has a method toURL() which seems to match your needs.

Kind regards,

 Rob

Hi Rob,

Unfortunately the toURL() method silently throws an error, as does the file() method :(

One solution is to copy the select file to the application directory and access the copy. However, if someone selects a massive audio file then it could take a good amount of time to copy the file before anything could be done with it, and that wouldn't be a very nice user experience. There would also be the issue of the application possibly consuming large amounts of HDD/SSD space.

I'm just not sure... it looks like question was already asked and answered on Stack Overflow:

Why duplicate it here?

Because I was unaware a similar question existed on that website.
