Great to hear that :)

See below :)

> gst-launch-1.0 filesrc location=../../fl/ads/41.avi ! decodebin ! videoconvert

> WARNING: erroneous pipeline: no element "clutter"

The element is named "cluttersink", not "clutter". And if it's not working,
please file a bug against "clutter-gst".

> gst-launch-1.0 filesrc location=../../fl/ads/41.avi ! decodebin ! videoconvert
> ! video4linux
> WARNING: erroneous pipeline: no element "video4linux"

The element is named "v4l2sink", not "video4linux"...

> gst-launch-1.0 filesrc location=../../fl/ads/41.avi ! decodebin ! videoconvert
> ! v4l2sink
> Setting pipeline to PAUSED ...

... which you use here. The problem however seems to be that your v4l2 device
video1 does not support working as a sink. Maybe you need to use a different
one (see the device property on the sink). Or if video1 is supposed to be
working as a sink, please file a separate bug about this and provide a debug
log with GST_DEBUG=v4l2*:6

> gst-launch-1.0 filesrc location=../../fl/ads/41.avi ! decodebin ! videoconvert

> Setting pipeline to PAUSED ...

Please file a separate bug for this if your device is supposed to have support
for fbdev (not to be confused with directfb!). In that bug again put a debug
log, this time with GST_DEBUG=6.

> Additionally mirsink on arm (does not exist on x64) also fails

That's something to report to the Ubuntu folks, it's their sink :)
