Hello.
I tried trawling through the archives but couldn't find anything too
relevan. Sorry for bothering if this issue has been discussed previously.
This message is being sent to the softdevice mailing list instead of the
mplayer plugin developers, as I have a feeling that the problem really
lies more withing softdevice than mplayer.
I have a peculiar problem trying to use Softdevice and the VDR Mplayer
plugin at the same time. The symptoms are as follows: (snip from ps -ax)
7177 tty1 Tl 0:35 vdr ....
-P softdevice -vo xv:full -ao alsa:pcm=default#ac3=plug:spdif#
-Pmplayer --mplayer /usr/share/vdr-plugin-mplayer/mplayer .....
7183 ? S 0:00 [kdvb-fe-0]
7229 tty1 T 0:00 /bin/bash /usr/share/vdr-plugin-mplayer/mplayer
/my/video/file.avi
7269 tty1 T 0:00 /bin/bash /usr/share/vdr-plugin-mplayer/mplayer
/my/video/file.avi
7270 tty1 T 0:00 /usr/bin/mplayer -identify -vo null -ao null
-frames 0 /my/video/file.avi
7271 tty1 T 0:00 grep -i -e ^ID_
As can be seen, all interesting processes (vdr itself and all its child
processes) are in state T, i.e. stopped (or being traced, which should not
be the case here). The Mplayer script (and everything above/below it)
stops at this point:
TEMP1=`$MPLAYER -identify -vo null -ao null -frames 0 "$FILE" 2>/dev/null
| grep -i -e "^ID_"`
As can be seen, the processes are all stopped. Sending them SIGCONT (once
or thousands of times or everything in between) doesn't help.
Now here is where I think this issue is tied to softdevice: When I run the
mplayer script without the softdevice plugin (with dummy or stream
output), everything works fine. When I run mplayer with the same options
as the script runs outside VDR (with $DISPLAY set properly, of course)
everything again works fine (except that VDR is still running in the
background so I get a hit on CPU performance and two distinct audio
streams.. :) The only thing that gets hung is mplayer spawned from under
VDR with softdevice running. Softdevice synch settings (usleep, sig or
rtc) don't have any effect on this behavior.
You might of course inquire why I don't use Softplay. I do, and would
prefer that over mplayer - if it would play my files correctly.. I have
all kinds of synch problems with many DivX/Xvid files even though some
others play fine. This is of course understandable, as Softplay is still
in version 0.0.2... :)
So. If anybody has _any_ idea on how to start debugging this problem,
please respond.
Kind regards,
Samuli
