Package: kazam
Version: 1.4.5-2
Severity: important
Dear Maintainer,
Kazam used to work without any issues until yesterday.
I found out that after a system update, I ceased to be able to record anything
with it if I wanted to include sound (it worked for video-only recording).
When I click "Capture", seemingly nothing happened.
I starting Kazam in a terminal and saw the log that you can find in the
attachment.
Following the last line in the stack trace, it seems to fail because the
following function returned None:
self.audioenc = Gst.ElementFactory.make("lamemp3enc", "audio_encoder")
So, after some research, I found that gstreamer1.0-plugins-ugly no longer
includes the lame MP3 encoder, and that it is now included in
gstreamer1.0-plugins-good starting from version 1.13:
+ Build-depend on LAME, mpg123 and twolame and add Conflicts/Replaces as
needed for gst-plugins-ugly from where the plugins moved.»
http://metadata.ftp-master.debian.org/changelogs/main/g/gst-plugins-
good1.0/gst-plugins-good1.0_1.14.0-1_changelog
I had gstreamer1.0-plugins-ugly version 1.14 installed, but
gstreamer1.0-plugins-good version 1.12. So I ended up not having any lame
encoding plugin at that point.
So, to avoid this, I suggest that kazam declares a dependency on
gstreamer1.0-plugins-good >= 1.14 (I didn't test with 1.13, so I can't tell for
sure if it'd be OK to depend on that instead).
Moreover, two additional notes:
* If this voids the need to depend on gstreamer1.0-plugins-ugly, that
dependency can also be removed now.
* This was a somewhat hard to debug situation, and what was happening was not
obvious at all.
Kazam should inform the user if a dependency is missing. Something was
obviously wrong as nothing happened when I clicked "Capture", but this would be
very hard to fix by someone unwilling to delve into stack traces, code and
package changelogs.
Thanks and best regards,
Luís Picciochi Oliveira
