Conversion problems with mencoder

[danielrhodes]

For some reason, I am having a ton of problems encoding a video to FLV. Mencoder is running in cron, and after it successfully encodes one video, it always fails on subsequent other videos by only encoding a partial file (always 12KB).

Using the following command line:

/usr/local/bin/mencoder /usr/local/www/data/video_queue/new/84c2245f6db05cce008ec0ced7716088-12.flv -vf pp=lb,scale=400:300 -srate 44100 -oac lavc -lameopts vbr=2:q=3 -ovc lavc -lavcopts vcodec=flv:vbitrate=400:keyint=30:acodec=libmp3lam e:abitrate=128 -of lavf -ofps 29 -o /usr/local/www/content/e/7/4616.flv > /tmp/videoEncoderLog

The output I get from Mencoder is this:

Has anybody seen this before?

[45tripp]

no,
course i don't know cron.

are you saying it always happens on the second run?
regardless of source?
that if you run the same source but first it works?

try without cron.
