Uncaught TypeError: Cannot read property 'codecs' of undefined with HLS and Media Player library

[GoogleCodeExporter]

This appears to be a new issue as of this afternoon. Not sure if maybe there 
was a revision bump to the Media Player library recently.

When loading the attached m3u8 (2250.m3u8, or any other m3u8 without multiple 
bandwidths), the Media Player library throws "Uncaught TypeError: Cannot read 
property 'codecs' of undefined".

Unfortunately, the source is minified and there are no source maps enabled, but 
using Chrome's pretty-print feature, I can see that the error comes from line 
3570 of the prettified media_player.js. Specifically, the error occurs here:

`this.codecs = a.v[0].codecs;`

Here, `a.v` is an empty array. This seems not to be the case when I load any 
m3u8 with multiple bandwidths (like the attached index.m3u8), in which case the 
`a.v` array is populated with one object per representation.

Apologies for the lack of better details, but a without source maps or an 
unminified version of the code it's pretty difficult to track things down.

We made an update today so that might be the cause; we are looking into it. 
Thanks for reporting.

Can you share URL of manifest that made this error?

I cannot reproduce this problem with given manifest file. 

Latest media_player.js is supposed to remove audio streams from the manifest 
mixed with audio and audio/video codecs. Given error can happens, if all 
streams are removed from manifest. I need to understand how such a case happen.

Or it can happen when manifest file has no streams from the beginning.

Unfortunately, I can't put the stream URL up on a publicly accessible page. I'd 
be more than happy to provide you with the URL if you want to email me though.
