Full length movie does not show up in Video lens

The only difference with these two video files are that Audio track in the trailer is 44100Hz sample rate and the full length movies has 48000Hz samplerate. Audio and video codecs are the same.

This seems to be a failure from GstDiscoverer. In particular, error code 5 is GST_DISCOVERER_MISSING_PLUGINS.

Perhaps try installing gstreamer1.0-plugins-base-apps on the device and run "gst-discoverer-1.0" on the two files to see if that shows any differences.

I used a couple of freely available files in different containers and audio/video formats from https://peach.blender.org/download/ , https://durian.blender.org/download/ , https://orange.blender.org/ , https://mango.blender.org/ , http://support.hp.com/gb-en/document/lpg40911 , http://mcpd.pagesperso-orange.fr/Avistep3/index_en.html and http://sourceforge.net/projects/matroska/files/test_files/matroska_test_w1_1.zip/download so everybody can reproduce the issue(s). The matching parts from my ~/.cache/upstart/mediascanner-2.0.log are attached. I don't seem to have a "mediascanner.log". There are no return codes reported in the error messages.

I'll add a failed case here for convenience and reference:

New file was created: /media/phablet/3151-268D/Videos/big_buck_bunny_480p_surround-fix.avi.
Extracting metadata from /media/phablet/3151-268D/Videos/big_buck_bunny_480p_surround-fix.avi.
Error when adding new file: Unable to discover file /media/phablet/3151-268D/Videos/big_buck_bunny_480p_surround-fix.avi

The service seems to corrupt memory and crash a lot if "enough" files have to be scanned.

Any updates on this?
