Bug#825294: smplayer: Opening directory takes a very long time

[Sven Joachim]

Package: smplayer
Version: 16.4.0~ds0-1

Opening a directory (Open -> Directory... -> Choose) to play all files
in it takes a very long time (depending on the number and the size of
the files of files in it, but a CD rip just took several minutes),
during which smplayer is unresponsive and appears to be hung.  During
that time it starts several mplayer processes whose commandline I was
able to catch:

,----
| $ cat /proc/31680/cmdline 
| /usr/bin/mplayer-noquiet-slave-identify-frames1-vonull-aonull/home/sven/music/A_Real_Live_One/04-Wasting_Love.ogg
| $ cat /proc/31720/cmdline
| /usr/bin/mplayer-noquiet-slave-identify-frames1-vonull-aonull/home/sven/music/A_Real_Live_One/07-Afraid_To_Shoot_Strangers.ogg
| $ cat /proc/31751/cmdline 
| /usr/bin/mplayer-noquiet-slave-identify-frames1-vonull-aonull/home/sven/music/A_Real_Live_One/09-Heaven_Can_Wait.ogg
`----

Only when the 11th and last song in the directory was processed this
way, the first actually played.  It seems to me the problem is that
smplayer passes "-frames 1" to mplayer which does not work as intended
for audio files.  Perhaps it should use "-frames 0" instead?
