pulseaudio support, broken nspluginwrapper/flash

[William Pitcock]

Binary package hint: ia32-libs

greetings,

this week's fun in ia32-libs is adding pulseaudio support for proper flash integration in Ubuntu on amd64.
i'll work out what packages need to be added for most optimal pulse support (e.g. SDL too) and make a patch
when i have time.

we need more libraries due to new GTK:
   libpixman-1-0 (flash)
   libsepol1 (flash)
   libselinux1 (flash)

and for libflashsupport, we need these:
   libpulse0
   libpulse-browse0
   libpulse-mainloop-glib0
   libpulsecore5 (may not need this one, but it wouldn't hurt)

thanks.

this is a bug in flash not closing its sockets which the libflashsupport package solves, see the linked bug

[Oliver Grawert (ogra)]

forgot to mention, libflashsupport is in the archive for hardy ....

[William Pitcock (nenolod)]

Hi Oliver,

Thank you for taking the time to triage this bug. You have made several details wrong, including:

   * libflashsupport is being built as 64bit code on amd64, so it cannot be loaded by the flash plugin.
   * this is not a bug in pulseaudio

Please do not edit bugs without reading them in the future, but do work to improve
Ubuntu.

[William Pitcock (nenolod)]

Hi again, Oliver.

This bug has to do with ia32-libs, as we are working to make a 32-bit module which links against ia32-libs (multilib) for amd64 users. Please do not triage this bug again.

[Edward (edward-coffey)]

Is there a work-around for this? Or a fix likely in the near future?

[William Pitcock (nenolod)]

I intend to poke some people about this, this week.

This bug was fixed in the package ia32-libs - 2.2ubuntu4

---------------
ia32-libs (2.2ubuntu4) hardy; urgency=low

  * fetch-and-build: Let BUILD default to 0, since we never actually use
    BUILD=1 in Ubuntu.
  * Add libpulse{0,-browse0,-mainloop-glib0,core5}, libpixman-1-0, libsepol1,
    libselinux1. This unbreaks Flash, Skype, Adobe Reader, and probably a few
    others. (LP: #183173, #155015, #180478)

Dear all,

there is still a problem with the support of pulseaudio for 32bit app that is:
libpulse0 depends on libcap1 which is not in the packaged libs.
I have finally got flashplugin sound using pulseaudio (and not alsa or other way) by
1. adding the corresponding /lib32/libcap*
2. also adding a 32bit version (so not the one of the 1.9-0ubuntu1
package) of libflashsupport.so in /usr/lib32

Note that no other pulseaudio 32bit libraries (libpulse-*) which are also missing
dependencies in ia23-libs are required for that purpose.

Best regards,
Patrice.

[Martin Pitt (pitti)]

So this needs libcap1 and libflashsupport added.

[Launchpad Janitor (janitor)]

This bug was fixed in the package ia32-libs - 2.2ubuntu7

---------------
ia32-libs (2.2ubuntu7) hardy; urgency=low

  * Add libopenal0a (LP: #191967)
  * Add libflashsupport and libcap1 (LP: #180478)
  * Update packages to current Hardy versions.

Regarding 32-bit SDL which William has mentioned in brackets, one possibility is to add multiple packages like ia32-libs-sdl-alsa, ia32-libs-sdl-pulseaudio and optionally make ia32-libs depend on at least one of them (and e.g. the pulseaudio variant by default).

[NY00123 (ny00)]

On a side note (tested with a 64-app and SDL but may be related to the 32-bit variants as well):
I've noticed that the sound in the Epiphany game (epiphany package) works better with SDL->ESD than with SDL->PulseAudio;
Which means that maybe the ESD variant of SDL should be provided by default, although there could be a game which works better with SDL->PulseAudio than with SDL->ESD.

[Ernst Persson (ernstp)]

flashplugin-nonfree should no longer depend on libflashsupport which in turn shouldn't be built for amd64 anymore.

[Jeremy Wilkins (wjeremy)]

This problem either hasn't gone away, has changed or has regressed for me. I have all the newest packages mentioned above and flashplugin-nonfree still doesn't install.

Here is output when I try to continue the install with apt-get install -f:

Even a full purge and reinstall doesn't seem to fix it. What is up here?

[ski (skibrianski)]

Just wanted to add that ffox3rc1 broke flash for me on two different systems. For me the magic workaround was to nuke all the flash stuff, reinstall the x86 libs, and then install flash and nspluginwrapper again. DaFlame, give this a try and see if it works for you:

sudo dpkg -P flashplugin-nonfree libflashsupport nspluginwrapper ; sudo apt-get --reinstall install libc6-dev-i386 libc6-i386 ia32-libs ; sudo apt-get install flashplugin-nonfree nspluginwrapper

I'm guessing the problem here was that when stuff was pulled into ia32-libs, the version I actually had on disk was from a different package, and dpkg got confused.

[ski (skibrianski)]

I also had this problem with ffox 3.0.3, and the above dpkg/apt-get sequence worked for me again too. The funny bit is I forgot all about the problem and was going to thank the author of this post, but he turned out to be me :-)

That isn't helping me unfortunately; I'm seeing the following out of firefox:

other errors in there include:

Flash works for a while (but without sound) - and then dies; it seems to die more than on Hardy;
but frankly this has never been stable - on the plus side it seems to be working again in Konq 4 (not sure about
sound)

I do wonder where the '$LIB' is coming from in that path.
