Cannot find ffmpeg but fine after a restart!?

Hey, I have something weird happening with my installation. I have the recommended installation (compiled from the serviio source) of ffmpeg:

  Code:

 which ffmpeg
/usr/local/bin/ffmpeg

However if the system starts from fresh, I get this error in the logfile whenever I try to play a file that needs transcoding:

  Code:

2012-05-02 21:58:33,104 ERROR [ProcessExecutor] Fatal error in process starting: Cannot run program "ffmpeg": java.io.IOException: error=2, No such file or directory
2012-05-02 21:58:40,606 ERROR [ResourceTransportRequestHandler] Error while processing resource, sending back 500 error. Message: Transcoded file '/home/alex/tmp/serviio/Serviio/transcoding-temp-11530-ASF.stf' cannot be found, FFmpeg execution probably failed

The bizarre thing is, if I restart serviio with a "sudo /etc/init.d/serviio restart" then the file will play with ffmpeg with no issues. although I do get this:

  Code:

2012-05-02 22:05:23,218 WARN  [ProcessExecutor] Process ffmpeg has a return code of 137! This is a possible error.


Any ideas of what is going on?

enable detailed log and ry it again. there should be the ffmpeg command that fails, try to run it manually
