Comment:

 The issue that GStreamer (or at least some versions of GStreamer) cannot
 detect audio in high-bitrate ogg files (bitrate > 25MBit) and subsequently
 fails playback completely can be reproduced when reencoding the attached
 sample Video20150609_185820_.mp4 (the duration is always correctly shown
 here). It works fine here with {{{-q:v 6}}} and {{{-b:v 15M}}} (leading to
 ~20MBit) and fails here with {{{-q:v 7}}} and {{{-b:v 20M}}} (leading to
 ~25MBit).
 I don't think there is any indication for a bug in FFmpeg.
 The output file does not play here with GStreamer, I believe the issue is
 reproducible with versions 1.0 and 0.10.
