Re: [orca-list] will firefox 20 be an improvement

[Peter Vágner <pvdeejay gmail com>]

Hello,
Opus codec is by putting it really verry simple a merge of xiph celt and 
skype silk codecs which became an RFC standard. It brings low latency 
audio with considerably better quality ranging from 8 to 512 kbits.
Having this coupled with web RTC a real time communication API for web 
developers it is now theoretically possible to build really powerfull 
rich web based multimedia apps. http://twelephone.com/ is my example of 
choice. With Firefox 23 and newer we can just open such an app from the 
browser and participate in a voice or video chat with good sounding audio.
Also for quite some time there is a pdf js project what is a pdf 
rendering engine written in java script. For a while this is available 
as a downloadable firefox extension. I haven't yet caught on this also 
but judging from the comments it is now going to be a part of firefox. 
For end user it means it is now possible to get pdf documents viewed 
directly in the browser. PDF JS uses HTML 5 features such as the canvas 
component. Such pdf documents rendered in Firefox are readable however 
navigation keys are not working like on the web. I can't say if this is 
because many PDF documents are not authored correctly or whether canvas 
accessibility is lacking or even something else.

Greetings

Peter
