Hello,
I'm experiencing ring buffer overflows with streamdev-server and the
following remux script:
tmpdir=${TMPDIR-/tmp}/externremux-${RANDOM:-$$}
FIFO=$tmpdir/out.mkv
OUTLOG=$tmpdir/out.log
mkdir -p $tmpdir || exit 1
mkfifo $FIFO
(cat $FIFO; rm -rf $tmpdir) &
ffmpeg -threads 2 -i - -deinterlace -vcodec libx264 -vpre veryfast -b
900k -bt 50k -maxrate 900k -s vga -acodec libfaac -async 1 -ac 2 -ar
44100 -aq 128 -sn -y $FIFO 2>/tmp/ffmpeg.log
My outgoing line is a VDSL2 line with a 2048kbps upload.

When this happens, the picture freezes and it never recovers. Sometimes,
there's also this suspicious extra error message (the first line):
2011-07-09T21:16:28+02:00 localhost vdr: [593] ERROR: read failed:

2011-07-09T21:16:29+02:00 localhost vdr: [25625] ERROR: 58 ring buffer

2011-07-09T21:16:34+02:00 localhost vdr: [596] buffer usage: 90% (tid=595)
Any advice on how to fix the problem?
Thanks!
