[DRE-maint] Bug#766020: ruby-gstreamer: Overflow of nanoseconds on 32-bit platforms

[Mario Lang]

Package: ruby-gstreamer
Version: 2.2.0-5
Severity: important

Querying position and duration information on a 32-bit platform
is more or less completely useless, since the unit of time
returned by GStreamer is nanoseconds, which does not fit (and therefore
overflow and wrap) into a 32-bit value:

---<snip>---
require 'gst'

bin = Gst::parse_launch("playbin")
bin.uri = 'http://delysid.org/music/delYsid-delUxe.ogg'
bin.play
sleep 1
result, dur = bin.query_duration(Gst::Format::TIME)
puts dur
---<snip>---

On this 32-bit system, I get:

-1010310203

which nicely confirms the overflow.


I am actually not sure if this is a problem with GStreamer API, or with
the GStreamer Ruby bindings.  I am filing against the Ruby bindings
because this is where I noticed the bug.

Note that everything works fine on a 64-bit platform.
