Google music stoppped playing any songs (GStreamer 1.0; Ubuntu 13.04, Fedora 19)

Thanks for taking the time to report this bug. However, I need more
information to investigate it further. Could post debugging output
from Nuvola Player unstable? See
http://nuvolaplayer.fenryxo.cz/support/bug_reporting.html for help.

Thanks.

I was not able to reproduce your issue on Ubuntu 13.04 64bit at first,
but it is reproducible after installation of all system updates with
the same error message in the debugging output:

EDIT2: Downgrading these packages did not fix anything:

              gst-plugins-base-libs-1.0.8-1 gst-plugins-good-1.0.8-1 gstreamer-1.0.8-1
              lib32-alsa-lib-1.0.27.2-1

The issue is always reproducible if Nuvola Player tries to play music via HTML5 Audio with GStreamer 1.0 backend (Gstreamer 0.10 works great though). Then ‎installed Flash plugin 11.2.202.297 via package nuvolaplayer-flashplugin from Nuvola Player Unstable Builds PPA and the issue disappeared on two U13.04 instances, but still persist on the third one.

I'm descreasing importance, because the issue seems to affect only one service.

Note to self: The third U13.04 instance doesn't probably work because npviewer.bin fails to load required libraries. Diff attached.

Dear users, could you attach file "npviewer.bin-libs.txt" produced by following command when trying to play? (Please use Add attachment or patch link on bug page instead of services like pastebin.com.)

sudo pmap `pidof npviewer.bin` | awk '{ print $4}' | grep lib | sort | uniq > npviewer.bin-libs.txt

Attached as requested.

I get this error and an empty txt file.

$ sudo pmap `pidof npviewer.bin` | awk '{ print $4}' | grep lib | sort | uniq > npviewer.bin-libs.txt
pmap: argument missing

$ pidof npviewer.bin
$

Don't return any result too (with the arrow turning for at lease 30 sec trying to play song)

KruyKaze and ghislaingeffroy: Do you have HTML5 audio turned off in Music labs settings and installed package nuvolaplayer-flashplugin?

Alex Thompson: Same case as in my testing, ALSA libraries are not loaded, so no playback is possible.

My bad I didn't have the unstable ppa on this system . I attached the file here.

No, I tryed to make it work without flashplugin as before this bug.
My bad.

Same problem as above:

pmap: argument missing

Hello there guys!
I'm a bit confused on what's causing this myself. I'm going to try and see if an extension of tweak for Nuvola Player is causing this. Anyhow, won't play on Google Music here either. See the attachment for details. Also doesn't work regardless if HTML5 audio is on or off.

Also if this helps, you can try disabling any extension for the player and disabling any tweaks to the service and it will still do the same thing. It seems to just spin and spin the arrow next to the song title at an attempt to stream, but fails. So hopefully that will assist in further isolating the problem.

The problem seems to be somewhere in WebKitGtk-libsoup-Flash-ALSA stack, not in Nuvola Player. Google Music doesn't work in WebKit's GtkLauncher neither.

Same thing on Fedora 19 64-bits compiled by hand.

Was working very well before. Now Flash and HTML5 don't work.

Since the underlying cause appears to affect multiple distros and recently popped up with newer packages, I left a message for the GNOME developers. We need to track down this bug. I suspect since it affects such a broad amount of Linux distros, the problem needs the help of a GNOME developer or someone at Google or Adobe (possibly, just an educated guess) to be fixed. So, seeing as donations were almost complete for the GNOME Fundraiser, I left some cash along with a message for anyone responsible for the package to see if the bug occurs upstream, or is just something certain distros have "patched" resulting in this bug. Anyhow, I figured kill THREE birds with one stone - fix a bug in Nuvola that stems from another application by fixing a (possible) GNOME bug that will also fix other applications, while at the same time fueling donations to make work like this possible. I believe this is out of Jiří's direct control, so getting the attention of the GNOME people shouldn't be in vain. I mean, as the developer for Nuvola, you could possibly fix this, but since it's not your application that's causing the issue, I figured you don't need even more extra unpaid work. So, after having worked with GNOME's developers before (despite all the negative stigma) they will either fix the bug or get us pointed in the right direction. I sounded the alarms and help should be on the way when time permits.

Many thanks for that - I am sure the contribution will be greatly appreciated!

Do you have a link to that bug report Mike? Thanks.

There's no upstream bug report in GNOME... Yet anyhow. There will be as soon as I am told what package this affects and I can get ahold of enough log files to file a report with GNOME. Since I have yet to file the bug report (sorry if I came across as having filed it yet) I will get on filing a bug report ASAP. First, I'll need to know the package(s) affected. Then, I'll need to get some more detailed logs, from either myself or a Nuvola user/developer, and then I'll finally have to get someone (likely from GNOME) to track this bug down and confirm it's a bug in a pure GNOME package, not just Ubuntu's package of whatever. Finally I can link back here and we can get some noticable progress towards fixing this. So I need some help.

So first answer me this - what package is affected by this bug?

I do not know. I thought you did . My guess would be webkitgtk-3.0-0 ?

Nope, but your guess did help me get on the right track. See:

https://bugs.webkit.org/show_bug.cgi?id=118945

It would be nice if you all (including Jiří, when he has time if needed) could help me push this bug along. Seeing as it effects multiple distros my bet is first I'll have to get the attention of a GNOME or Webkit developer so I can debug the problem further (I am not used to debugging Webkit issues, yet) and then after those guys fix it, I will report it to Ubuntu asking them to include the patch that the GNOME developers more than likely will cook up. It will be up to you guys to see if it effects your Linux distro and asking them to patch it. I can try to get the Ubuntu people to patch our version of libwebkitgtk-3.0.0. But I need help if you guys want Google Music to work again on every single distro affected by the bug.

Sorry about that. Trying to mark it as affecting both Nuvola Player and libwebkitgtk-3.0-0.

Also for anyone wishing to help me advance this bug, see also http://webkitgtk.org/
And yes there is an entire IRC channel dedicated to the library #webkitgtk+ at irc.freenode.org
You call can use these resouces as well to investigate this bug.

I just did a +1 on that bug report.

It seems I've figured out why MP3 playback via HTML5 Audio fails. Google Play Music uses a MP3 file embedded in a data URI to check support for HTML5 Audio, but the test never finishes (spinning arrow) because an issue in GStreamer 1.0. I will contact someone at GStreamer's IRC room to get help with this issue.

Well, that explains the HTML5 audio issue, good luck with that. Two questions - should I keep that bug report open relating to libwebkitgtk-3.0.0? Because Flash still has playback issues. And also, since this is an issue with GStreamer, and I use the Fluendo Codec Pack, (which user GStreamer) should I contact the Fluendo people as well? Fluendo Codec Pack isn't open source, but I do pay for suppport, so they should be able to fix it if they need to. I'm just wondering with regards to Fluendo Codec Pack since it utilizes GStreamer.

From GStreamer IRC: Tim-Philipp Muller (__tim) was able to reproduce
the issue in Gstreamer 1.0.x, but it seems to be already fixed in git
master (development branch). I've created a bug report against
Ubuntu's GStreamer package[1]. Please, read the bug report, try to
reproduce the issue with and click "This bug affects me too".

I would keep it open for now.

If you have Fluendo Codec Pack for GStreamer 1.0 (not 0.10) and are
able to reproduce issue with `gst-launch-1.0 playbin
uri="data:audio/mpeg;base64,//DATA HERE"` from the bug report above,
you could contact then. However, I would suggest you to post a log
here before doing so.

Could anybody try to run Nuvola Player with following environment variables?

GST_PLUGIN_SYSTEM_PATH=/dev/null GST_PLUGIN_PATH=/dev/null nuvolaplayer -D

This hack should make GStreamer backend completely non-functional, so
Google Play Music should fall back to Flash plugin based playback.

I get the same crash after trying this.

I went from stable release suffering the problem. I changed my repo to unstable to install nuvola-flashplugin, upgraded nuvolaplayer to the current unstable, applied the env's using export and ran nuvolaplayer -D. The client launches, and gets to perhaps 20% of loading the Google Play library before the crash.

I also ran the same build of nuvolaplayer with the same command from another shell (so no env's) - this still launches and still suffers the same "wheeling" issue on playback as before.

Are you sure you have turned HTML5 backend off in Nuvola Player
preferences (menu Application → Preferences → tab Service → turn off
HTML5 Audio and menu Go → Refresh)? I cannot see it in the log.

My bad I thought I needed to disable it in "music labs".
It is working now awesome!

So it seems we have found a workaround for the GStreamer bug. Ugly, but working. I will commit it to trunk branch and backport it to stable series soon.

Thanks for taking time to help with searching for a cause of the issue and testing workarounds.

Fix committed to lp:nuvola-player as r731. Will be available in next unstable builds and will released in Nuvola Player 2.1.0.
<http://bazaar.launchpad.net/~fenryxo/nuvola-player/trunk/revision/731>

The fix won't be backported to the current stable series 2.0.x, because it introduces new dependency (libgstreamer).

I noticed that this workaround also fixes the bug where a song will replay from the beginning when you pause it for a certain period of time.

Well, sorry for taking so long. I upgraded my laptop and had to start fresh. Anyhow, after typing in what Jiří said earlier, here is the output. I have the latest version of Fluendo Codec Pack installed. Can anyone tell if this is the same/similar error from the output on the terminal?:
mike@mike-Aspire-X1430:~$ gst-launch-1.0 playbin uri="data:audio/mpeg;base64,//DATA HERE"

mike@mike-Aspire-X1430:~$

And if that is the same error, where would I look for the log file?

I just reported this bug report, along with the details and links to not only this bug report, but the GNOME and Ubuntu bug report to the Fluendo support team. I'll update on how stuff goes on their end. Hopefully with all these people aware of the bug, it will be fixed without a dirty hack sometime in the future.

The bug has already fixed in a development branch. See
https://bugs.launchpad.net/ubuntu/+source/gstreamer1.0/+bug/1204672

Also, you can close the bug you have filled in WebKit bugzilla, the
issue is in GStreamer, not in WebKit.

The fix has been released in a freshly baken Nuvola Player 2.1.0,
download it while it is still hot. Happy listening!

Colin Guthrie posted on Google+ page:

FWIW, I did a little digging into the Google Music + GST problem.

I dug a bit in the GST code and the basic problem is that URLs decoded via dataurisrc seem to operate in "pull" mode and even although the "caps" are supplied, the "type find" system does not do a query for caps when operating in pull mode, so tries to guess the type from the URIs "extension" and (obviously) fails miserably.

Even if I hack the dataurisrc to fake the URL to the rest of the pipeline (i.e. give it a .mp3 extension) it still fails, but I suspect this is simply due to one frame not being enough data for detection, which is all the base64 encoded data contains (piping the data through base64 -d and playing with playbin fails with the same detection error, but setting up a manual pipeline decodes it fine, suggesting that the fix in GST is indeed to honour any caps set even in pull mode).

I found a reference to a similar problem on the GStreamer-devel mailing list: http://gstreamer-devel.966125.n4.nabble.com/Handling-force-caps-from-playbin-td4665303.html

As I know Sebastian, I've sent him a quick mail to see if there is anything in the works to address this. Will let you know when he gets back to me.

> I've sent him a quick mail to see if there is anything in the works to address this.

The issue doesn't occur in GStreamer 1.1.x, so soemthing has been changed between 1.0.x and 1.1.x.

FWIW, the above comment from me) is more related to https://bugs.launchpad.net/ubuntu/+source/gstreamer1.0/+bug/1204672 I believe as this is a GST issue, not related to code here.

FWIW, I can still reproduce the issue with upstream gstreamer 1.2.2 (both base + plugins-bad for the dataurisrc)

I've got some more info on the usptream bug I reported. https://bugzilla.gnome.org/show_bug.cgi?id=729625

If you can no longer reproduce the issue on your GST install, then it's probably worth a comment on the upstream bug. As mentioned, I can very much still reproduce the problem both with the gst-launch example with the data: uri, or a gst-launch with the data converted to a real file, and inside nuvola player itself as a practical example, and this is with gstreamer 1.2.2.

All the best and I look forward to enjoying what looks like a great player!! :)

OK, so done a little more hacking... and by hackng I mean *hacking* :D

I made a really evil patch for GST that detected this specific test URL and hard-coded the caps. This patch is sufficient to make the test pass with a simple gst-launch-1.0 pipeline on the command line, but sadly this doesn't seem to be enough for Google Music and it still requires the Flash plugin.

From appropriate GST_DEBUG= values, it seems to be querying the duration. I guess it needs to validate that the duration of the decoded audio is correct to ensure the decoder is correct. Sadly I am now at a loss. GST doesn't seem able to supply the duration of the test URL and while I can hack in various values, I'm somewhat stabbing in the dark to work out what duration to try and supply to fool it.

If someone can work what duration it needs, I can maybe try it out.

Anyway, here's the horrible patch to GST to make it play the test URL OK.

> FWIW, the above comment from me) is more related to https://bugs.launchpad.net/ubuntu/+source/gstreamer1.0/+bug/1204672 I believe as this is a GST issue, not related to code here.

You are right. This bug report (#1200818) is about which trouble the Gstreamer bug causes to Nuvola Player: the old GST 1.0.x bug made Nuvola Player hang during loading Google Play Music website. However, the new GST 1.2.x bug seems not to have this side effect.

As mentioned, I can very much still reproduce the problem both with the gst-launch example with the data: uri, or a gst-launch with the data converted to a real file, and inside nuvola player itself as a practical example, and this is with gstreamer 1.2.2.

I was not able to reproduce the issue with GST 1.1.x, only with GST 1.0.x. However, I have just tried GST 1.2.4 and it seems to contain a new bug. The both bugs cause GST not to be able to play datauri streams, but there is one significant difference: GST 1.0.x gst-launch-1.0 test command hangs and must be interrupted by Ctrl+C, GST 1.2.4 doesn't hang.

Also, the GST 1.2.4 bug seems not to affect Nuvola Player, I can play music through HTML5/Gstreamer with GST 1.2.4 (with HTML5 Audio enabled in Labs settings and inactive All Access subscription).

Great, I will post there my observations :-)

I'm having the same issue. I'm using nuvolaplayer 2.4.0-1 (package from AUR). When I try to play a song, the loading icon just keeps spinning.

* I have Google Play All Access,
* I have the "Load GStreamer to provide HTML5 Audio support" preference enabled.
* I have the HTML5 mode checked in my google play settings.

These are my currently installed gstreamer packages:

extra/gst-plugins-bad 1.2.4-1 [installed]
extra/gst-plugins-base 1.2.4-1 [installed]
extra/gst-plugins-base-libs 1.2.4-1 [installed]
extra/gst-plugins-good 1.2.4-1 [installed]
extra/gst-plugins-ugly 1.2.4-1 [installed]
extra/gstreamer0.10-base-plugins 0.10.36-3 (gstreamer0.10-plugins) [installed]

> I have Google Play All Access,

You have to use Flash plugin then. Google Play All Access doesn't support HTML5 Audio.
