Subject: [winswitch] mp3/vorbis support for xpra html5 client

Hi Calvin,

The Web Audio API seems extremely picky when it comes to decoding arbitrary
encoded sound data and doesn't seem to want to do anything with the mp3
chunks we get from an Xpra server (maybe needs alignment client-side). It
doesn't seem possible at this point to test for codecs supported by the
browser either. The ticket was #845.

The aurora.js library showed promise to decode the mp3 format and then pass
the PCM sample data to Web Audio API, but with everything else going on in
the page it will have a significant performance impact. It correctly
identifies the stream format but still doesn't want to decode the audio
data from an Xpra server without any preprocessing client side. But even
this doesn't make sense since most browsers should be capable of decoding
mp3 natively through Web Audio API anyway!

It is on my radar to look at this again at some point.

PS: It looks like I may have accidentally pushed the RPM repositories
early, so you may need to run a "yum clean metadata" if updating fails.

Subject: [winswitch] Problem to connect from Windows client
Message-ID: <5728585.vgWETiyioC@regdesktophome>

Hi,

I'm not able to connect with the Windows client to retrieve applications started with xpra. I 
have followed the instructions on https://help.ubuntu.com/community/Xpra[1] to start an 
application with a screen like:

server side:
$ xpra start :7
WARNING: low display number: 7
You are attempting to run the xpra server against what seems to be a default X11 display ':7'.
This is generally not what you want.
You should probably use a higher display number just to avoid any confusion (and also this 
warning message).
Entering daemon mode; any further errors will be reported to:
  /home/ron/.xpra/:7.log
$ DISPLAY=:7 xterm
which works fine, however, the last command doesn't return aat all but I confirm in a different 
shell:
$ xpra list
Found the following xpra sessions:
        LIVE session at :7

client side:
I start the Windows Xpra client application,
set the mode to ssh,
quality  Auto
Speed Auto
user at ip 22:7
password <empty>
Upon which I get asked for my users password tp establish the ssh session and I get 
immediately thrown abck into the xpra client with a message in red
"Connection Lost" - this while I have a second ssh connection open using putty - and I can 
confirm, that second session strays connected at all times. What's going on here? And how can 
I fix this?

Thanks,
Ron

Ancient bug which has been fixed a long long time ago, but completely
ignored in Debian and Ubuntu. And there are dozens more like this one.


> How can I get this to work?
Don't use the broken and outdated packages from Ubuntu or Debian and it
will be fine.
http://xpra.org/trac/wiki/Packaging#DistributionPackages

With an up to date version you can just do:
xpra start --start=xterm ssh:YOURHOST:DISPLAY
(the DISPLAY part is optional on other distros too)

Okay, So I went ahead and downloaded the sources for 0.16. from

dependencies listed for Debian based oses, executed 
./setup.py install --home=install but got this:

The pygtk headers in Ubuntu and Debian are also buggy, so you will need
to apply this patch to ignore the warning:
http://xpra.org/trac/browser/xpra/tags/v0.16.x/debian/patches/no-strict-prototypes-gtkitemfactory.patch
There are a few more patches in that directory which you may need to
apply... Building on Debian / Ubuntu is such fun, not.

Or you can just use the ready-made binaries we provide:
http://xpra.org/#download

Cheers
Antoine

PS: Ubuntu Trusty is no longer officially supported in the 0.16 branch
because the avcodec and swscale codecs do not build. (see previous ML
posts on the subject).
Though if you only use Trusty as a server, you may be able to get by
without those. There are packages in the beta area for it.

Hehe that's what I did, I downloaded & installed 15.10 and it works like a breeze! Awesome! 

Finally I can replace Xming with something better! Your help is much appreciated! Thanks
