Hi, thanks for your report.

If you can run kazam --debug from the console and make it crash, then please attach the debug output here.

I find audio isnt the issue. If I switch the screencast preferences to record with VP8/webM it no longer crashes. But if I record using H264/MP4 it does

This bug is a result of https://bugs.launchpad.net/ubuntu/+source/x264/+bug/1241772 "Miscompilation with gcc 4.8 (segfault in x264_cqm_init)"

A fix has been commited to saucy-proposed. You can either use that package (see above link for details) or use the following PPA.

https://launchpad.net/~maarten-baert/+archive/simplescreenrecorder
It's the original package from Ubuntu with the upstream patch applied to it.

For those who want to try it (at your own risk):

    sudo add-apt-repository ppa:maarten-baert/simplescreenrecorder
    sudo apt-get update
    sudo apt-get upgrade

Just to be clear (because I got confused), the given PPA is *not* a PPA that *just* contains a patched version of Kazam, it's actually another project (I mean SimpleScreenRecorder) and as far as I am concerned it serves my purpose completely (recording a screencast).
I would even say it is better than Kazam, but I think the point about Kazam is that it was trying (as much as possibile) to reduce the number of options, while SimpleScreenRecorder seems to let go of the options restriction and give more of these (but they're documented), but it's definitely not overcomplicated.
It would be great to have it included in the default Ubuntu packages list.

Regarding this bug, I had the issue as well, and as far as I understand, https://bugs.launchpad.net/ubuntu/+source/x264/+bug/1241772 is effectively the right explanation for this issue. Kazam's developer being apparently not so active maintaining it at the moment (see blog linked from the main Launchpad page), SimpleScreenRecorder is the only nice solution I can see under Ubuntu 13.10.

The bug is in the h264 / mp4 codec. You can work around this by instead setting vp8 / webm in the codec settings as follows:

"""
$ kazam --preferences
"""

Next choose Screencast, Record With, vp8 / webm.

Open kazam and record again to workaround the issue...

Is this still an issue in 14.04 and kazam 1.4.x or 1.5.x versions? If it is, I'd appreciate if someone posts a debug log and reopens this bug. Thanks!

Please start kazam with --debug option and try to reproduce the error. Just recently a crash when using area selection was fixed in the stable PPA. Unstable Kazam has this fixed for some time now.
