Istanbul freezes when recording ends with Record Sound

This is not reproducible on my side.

What is the version of istanbul you are using? It is quite possible that it didn't get updated. The problem you have specified was in Dapper version of istanbul.

mik@604:~$ istanbul --version
0.2.1

mik@604:~$ dpkg -l istanbul
ii istanbul 0.2.1-0ubuntu3 Desktop session recorder

I can confirm on my amd 64 bit it doesn't shut down after it has saved the file.

I'm using Edgy Eft with Istanbul 0.2.1, and I get the same problem.

If it helps at all, this is the terminal output:

istanbul

It appears to do this only when I have the Record Sound option checked. Otherwise, it works just fine.

confirming on feisty, istanbul 0.2.1

I can confirm what aysiu has reported: When I uncheck "Record Sound", the bug does not appear.

Marking confirmed as per comments.

I upgraded to feisty some months ago and the problem is still there, this is my output:

Not of all,

hi,

it looks like but since my bug report i have disabled pulseaudio and i
have the same problem.

I tried to debug istanbul. The sole thing i have seen is that when
python says to GST to stop the pipes, istanbul wait for dbus messages
from GST that never come.

Edouard

same bug in xubuntu 8.04 alpha5 , crash when i try to save my record .

Same thing here.
Since it's the same with xvidcap and gtkrecordmydesktop, it would be nice if someone could fix just one of those programs, so we can do screen recordings.

The Ubuntu Screencast team also suggest you record audio and video separately. I can't imagine what the problem is having both functions in one program... but then I'm not a programmer.
Ubuntu Screencasting tutorial:
https://wiki.ubuntu.com/ScreencastTeam/RecordingScreencasts

The bug is still present in Hardy Heron Alpha 6 with i915 video driver

This are the commands that instanbul calls. They work if you call them them on a terminal.

gst command line complete screen without 3d
gst-launch-0.10 oggmux name=mux ! filesink location=/tmp/tmppUzJ_f istximagesrc name=videosource display-name=:0.0 screen-num=0 ! video/x-raw-rgb,framerate=10/1 ! videorate ! ffmpegcolorspace ! videoscale method=1 ! video/x-raw-yuv,width=1280,height=800,framerate=10/1 ! theoraenc ! queue ! mux. gconfaudiosrc name=audiosource ! audioconvert ! vorbisenc ! queue ! mux.

I've nominated this problem for hardy since its not just a missing feature, but a total application hang and is 100% reproducible on my system (and others aparently)

The bug is still present in Hardy Heron final, nvidia video driver.

Confirming the bug for Hardy. ( istanbul version 0.2.2-2 ).
I try to record with sound, with mouse, without 3d.
I have a Thinkpad Z61m with fglrx driver... in case it matters.

The trayicon hangs and shows the tooltip "in process of saving to disk".

Another Confirmation -- only with sound enabled.

Hardy 8.04
Istanbul 0.2.2

~$ lspci | grep VGA
00:05.0 VGA compatible controller: nVidia Corporation C51 [Geforce 6150 Go] (rev a2)

Let's blame nVidia! :)

Happens in my Hardy box, too. With sound DISABLED.

Confirmed on Hardy Heron (8.04) on my computer as well. Sound is disabled and using a generic Intel onboard graphics chipset.

Istanbul allows me to click record, but then hangs and won't let my stop the recording.

The only way to stop it is to kill the process manually.

As a lark, I turned off Visual Effects and Istanbul started working properly. I don't have a way to input sound, but it looks like it at least works with Visual Effects (System -> Preferences -> Appearance -> Visual Effects -> None) turned off for my system.

Confirmed here. I was having the same problem (hanging after starting recording). After turning visual effects off, it works correctly.

This started after I did the Hardy upgrade from Gutsy (or very near then, at least).

Confirming hanging "in process of saving to disk" only when sound recording is enabled. Hardy Heron AMD 64

Is importance "unknown" ok? I think this is a CRITICAL bug of this application (at least its Ubuntu port).

Confirmed on Hardy Heron final. Changing visual effects has no effect for me, neither does turning off sound. However, if I run istanbul from a terminal window as root (sudo istanbul) it does finish writing the file, but the result is choppy and horrible quality.

I noticed the first bug report was in 2006 ! Is there ANY work underway on this ? I am having the same problem as oskar; since upgrade to Heron I can't use istanbul, xvidcap or recordmydesktop. Please don't make me use Windows for my project.

Confirmed it on Hardy Heron Final with Istanbul 0.2.2 except(!) for turning on 3D Record when running as root, as an unprivileged user nothing works.

I confirm this bug in my Hardy Heron too.

Confirmed on my Hardy Heron.

Tried running Istanbul as root, without 3D, without sound. All failed.

Tried disabling Visual Effects, works like a charm. Thanks to Jim's comment above: https://bugs.launchpad.net/ubuntu/+source/istanbul/+bug/63996/comments/27

I also can't run istanbull in Hardy 8.04.1. I have uninstalled it and installed gtk-recordmydesktop. It seems to work perfectly.

I can confirm this as well. On 8.04 including all updates it hangs and I have to kill the process. I cannot save any screencast and therefore istanbul is useless to me. Istanbul version 0.2.2

Could you please update the bug importance to critical?

This bug still exists with istanbul 0.2.2-4 on Intrepid. Upstream have committed a hacky patch, but since the last Istanbul release was Feb 2007, this hasn't made it to Ubuntu yet.

Remember that unchecking "Record Sound" is a workaround for this issue.

This bug is of medium importance, so I have marked it as such. Please read https://wiki.ubuntu.com/Bugs/Importance for an explanation of bug importance.

I confirm it doesn't work in hardy (ubuntu studio flavour). I tried with or without sound and using sudo or with normal user... it always hangs at the "saving to disk" stage.

I have the same problem in 8.10, it does not help to uncheck "Record sound" for, i'm using amd64, could this have something to do with the problem? I see others having the problem is also using 64bit

zpon: I experience the problem in a 32bit system, and my experience is exactly as described here (i.e. unchecking "Record sound" makes everything work), so it sounds like you might be encountering a different bug.

same problem here on Ubuntu 8.10 Intrepid with latest updates
unchecking "Record Sound" makes it work

Unchecking Sound does not help for me either, I can't find a workaround.
istanbul 0.2.2-4, interpid, Intel(R) Core(TM)2 CPU.
Attached is the output of istanbul --gst-debug-level=5 --gst-debug-no-color (gzipped).
Recording starts around line 16155 and stops right at the end.

I can stop istanbul using ctrl-C while it is recording. Once I try to stop it ctrl-C no longer works and I have to kill the process (send SIGTERM using killall)

It happens also here: unchecking "Record sound" does not help. Disabling desktop effect does.

Intrepid, istanbul 0.2.2-4, 32bit, nvidia graphics.

Only way to terminate istanbul is with SIGTERM.

I see a few people here claim to have the same freeze bug, but disabling "Record sound" does not fix the problem. I suggest you open a new bug report, as it sounds like a different issue.

Hew is correct, from what I can tell there are two errors here.

First - there is a problem with deskcasting with istanbul with the "Record Sound" option enabled. This bug, as far as I can tell, is 100% reproducible in the current version of Ubuntu (8.10). All errors regarding this bug, (and this bug only) should go in this bug report.

Second - there is a bug that arises from using istanbul with desktop effects enabled. I *can* reproduce this bug if I *do not* have the "Record 3D" option enabled. If I enable "Record 3D", istanbul works fine. This probably has something to do with istanbul not recognizing ANY GPU output when this option is not enabled, and having problems with the 2D acceleration used for compiz effects. Comments on this bug should into newly created bug bug 307827 .

Keeping these two problems separated helps cut down on the confusion and provides developers with more information to help fix the problem. Thanks for taking the time to help make Ubuntu better!

I don't have problem with compiz on, i make a video good (see the attachment), the problem is went record sound.
Other insure is wend i tried to record without 3d record, the video recorded no have good shape.
I think there are two bugs, the first one is record sound y the other is 3d record.
Other one is went i record one specific window, only record one area of the screen.

So... I've noticed this at the end of 2007, and this still happens with Ubuntu Intrepid 8.10.
Tried killing pulseaudio, removed alsa.... nothing.... installed OSS4 and the samething still happens when Sound Rec is on.
If we only had config options for Istanbul.... like audio settings. It's probably looking for some alsa config that doesn't even exist... or some other sound lib....

Istanbul appears to be unmaintained, so these bugs have just never been fixed. For those that are not aware, gtk-recordmydesktop is an application which provides similar functionality to istanbul, and may be useful for users that just want a stable screencasting app.

That's what I switched to and works for the most part.

I found that I had problems editing or viewing the resulting Ogg file
on some platforms so I use this ffmpeg based script to transcode the
file:

#!/bin/bash

INPUT_FILE=$1
OUTPUT_FILE=$2

ffmpeg -i ${INPUT_FILE} -s 960x720 -vcodec mpeg4 ${OUTPUT_FILE}

My experience reflected a misunderstanding rather than a bug.

I was getting these hangs when saving the video but when I read people saying about disabling Compiz (Visual Effects -> None) I thought that maybe we were thinking the wrong way.

You must configure istanbul whether you're using Compiz or not. Compiz is a 3D and "normal" Gnome isn't so I think that the video engine should switch accordingly.

Checking "Record 3D" while in my Compiz environment made the software work like a charm (and that's why it worked with this option unchecked + no compiz). So if compiz, "Record 3D" checked, not, unchecked.

The "Record Sound" issue has as responsible the great "pulse audio" because istanbul (and other apps) tries to access the sound device directly (/dev/..) in order of pulse audio. I think that this may be corrected by configuring environment variables or somenthing, havent tested.

Hope this helps somebody!

Regards from Brazil

I discovered this just accidentally, trying to set a higher video recording quality.

The issue mentioned above has been discussed at http://bugzilla.gnome.org/show_bug.cgi?id=430151 and there is a workaround at http://bugzilla.gnome.org/attachment.cgi?id=86405.

I hope it helps,

Pablo

I can confirm that this bug is still an issue on Ubuntu 9.10, and that the workaround suggested by Pablo Rodríguez works.

As upstream hasn't released a version of Instanbul with this fixed, I'm attaching a patch to the deb.
The source of this patch is https://bugzilla.gnome.org/show_bug.cgi?id=430151#c1

Hi David -
  This patch looks very good, but since istanbul is already using quilt to track source patches, could you re-write your debdiff to add a new quilt patch? There's some docs on using quilt at <https://wiki.ubuntu.com/PackagingGuide/Howtos/Quilt>

Since you're working on the diff, please don't use Debian's Closes: syntax for bug closers. The syntax here is just "(LP: #nnnnnn)". Also, please re-target the changelog entry for the current development release, Lucid.

I've unsubscribed ubuntu-universe-sponsors, but feel free to re-subscribe when you've had a chance to update the patch - I'd be happy to sponsor it then.

I applied the patch mentioned here http://bugzilla-attachments.gnome.org/attachment.cgi?id=86405 but it hasn't once worked for me.

The first run after patch application briefly showed the save-file dialog but it crashed before I could give focus to the window. Subsequent istanbul runs still exhibit the old pre-patch problem.

I'm on Karmic (2.6.31-17-generic) running the default repo version of istanbul.

Here's how I applied the patch:

- save the patch to, e.g. /tmp/istanbul-patch.txt
- cd /usr/share/pyshared/istanbul/main/
- sudo patch -b -p2 </tmp/istanbul-patch.txt

A backup is created in-case you need to revert to the original file.

I tried gtk-RecordMyDesktop but it has audio-video sync problems, so it isn't much of an option.

Without the patch, there is another workaround:

Since istanbul saves the recorded file to /tmp (with a random filename) after the recording session (even with sound and 3D turned-on), just go to /tmp and rename your file (it is already encoded as .ogv)

It appears that only the file-save dialog is improperly displayed (or not at all), but everything else works fine. I've tested it multiple times on Karmic (2.6.31-17-generic) running the default repository version (patched and unpatched). The quality is better than gtk-recordMyDesktop, especially a/v sync.

Thanks Evan. I've done what you asked.

This bug was fixed in the package istanbul - 0.2.2-5ubuntu1

---------------
istanbul (0.2.2-5ubuntu1) lucid; urgency=low

  * Applied patch to screencast.py to allow recording sound. (LP: #63996)
 -- David D Lowe <email address hidden> Fri, 18 Dec 2009 18:05:10 +0000

That's much better, thanks. I've uploaded the fix to Lucid, and the Launchpad Janitor should close the ticket when the upload is accepted.

Can someone help me implement this fix in Karmic?

Nevermind ... i got it sorted. the patch works by the way! Cheers

Just out of curiosity, when I have a high res set to record I can't get istanbul to work right...This is a real bother. Thank for the tip Saidimu

use XVidCap or wait another year to see if this is fixed. :-)

It might not work for all, but since Istanbul doesn't seem to be developed further, this is better than nothing.

15 people? that makes me laugh.
If I only knew how to do it...

I've moved on to XVid or VLC (yes it CAN Do screen capture video and audio).

This bug is marked as fixed for Lucid.

I had the same problem in Lucid. Then I tried closing all apps, including empathy and then it worked. I mean it didn't freeze. But it records only a bit of sound then starts cuting it up... basically still doesn't work with sound capture.

I had just assumed that all work had stopped on Istanbul. There are good
alternatives out there.

Every (in)decision matters.

Sorry for my previous comment, since I thought the patch wasn't applied.

There seems to be a new patch against CVS head, that might fix the problem (http://bugzilla-attachments.gnome.org/attachment.cgi?id=163377). It doesn't seem to work with version from Ubuntu 10.04.

I hope it helps,

Pablo

Well, at least 16 people have this problem with Istanbul - the 15 aforementioned and me.

I found a quite crude workaround: disable sound recording in Istanbul, use the gnome sound recorder, save both files as ogg, join images and sound in pitivi (also able to edit it a bit)

It works for me but it is still nuts. It should be possible to patch the packets shouldn't it. Istanbul is a nice application: simple, straight forward, integrates well into the desktop. It's a pity it has that glitch.

Conrad

Just installed the version 0.2.2-6 from ppa - and it works like a charm :-)

Thank you

which ppa?
