[MPlayer-dev-eng] [PATCH] demux_lavf: do not treat AV_NOPTS_VALUE as a valid duration value

[Reimar Döffinger]

Hello,
currently demux_lavf thinks AV_NOPTS_VALUE is a valid duration values,
resulting in weird total length values if the demuxer does not give a
duration.
Attached patch fixes it.

Greetings,
