<BR># rpm -qa | grep nuvexport<BR>nuvexport-0.4-0.20070630.svn<BR>
<BR>Running nuvexport --debug to transcode a DVB-T mpeg file to MP3 gives me the following commands:<BR>
<BR>You have chosen to export 1 episode:<BR>
<BR> 1. BBC News; Weather:<BR> (10/31/2006, 1:00 PM) 720x576 MPEG2 (4:3)<BR> No Description<BR>
<BR>* Separate multiple episodes with spaces, or ranges with '-'<BR>

<BR>--------------------------------<BR>To encode: BBC News; Weather: Untitled<BR>Use the following commands:<BR>
<BR>system call:<BR>mkdir -m 0755 /tmp/fifodir_21423/<BR>
<BR>forking:<BR>/bin/nice -n19 /usr/bin/mythtranscode --showprogress -p autodetect -c 1501 -s 2006-10-31-13-00-00 -f "/tmp/fifodir_21423/" --honorcutlist --fifosync 2>&1<BR>
<BR>forking:<BR>cat /tmp/fifodir_21423/vidout > /dev/null<BR>
<BR>forking:<BR>/bin/nice -n19 ffmpeg -threads 2 -y -f s16le -ar 48000 -ac 2 -i /tmp/fifodir_21423/audout -ab '196608' -acodec mp3 -f mp3 '/home/mythtv/BBC News; Weather.mp3' 2>&1<BR>
<BR>system call:<BR>id3tag -A 'Untitled' -a '1501' -c 'No Description' -s 'BBC News; Weather' '/home/mythtv/BBC News; Weather.mp3'<BR>
Cleaning up temp files.<BR>
----------------<BR>
<BR>Running the first forking command does generate the temporary folders:<BR>
<BR>$ ls -la /tmp/fifodir_21423/<BR>total 12<BR>drwxr-xr-x 2 mythtv mythtv 4096 Jul 10 12:34 .<BR>drwxrwxrwt 21 root root 4096 Jul 10 12:31 ..<BR>prw-r--r-- 1 mythtv mythtv 0 Jul 10 12:34 audout<BR>prw-r--r-- 1 mythtv mythtv 0 Jul 10 12:34 vidout<BR>
<BR>but after running the second forking command and the first process finishes the temp folder becomes empty:<BR>
<BR>$ ls -la /tmp/fifodir_21423/<BR>total 12<BR>drwxr-xr-x 2 mythtv mythtv 4096 Jul 10 12:36 .<BR>drwxrwxrwt 21 root root 4096 Jul 10 12:35 ..<BR>
<BR>Running the third forking command whilst the first two are running gives this response:<BR>
<BR>$ /bin/nice -n19 ffmpeg -threads 2 -y -f s16le -ar 48000 -ac 2 -i /tmp/fifodir_21423/audout -ab '196608' -acodec mp3 -f mp3 '/home/mythtv/BBC News; Weather.mp3' 2>&1<BR>

<BR>-------------------------<BR>
<BR>It looks like the command for ffmpeg is configuring the -ab correctly. Is the issue I'm experiencing a problem with transcode not correctly detecting the video parameters and passing them onto ffmpeg? <BR><br /><hr />The future of MSN Messenger! <a href='http://imagine-msn.com/messenger/launch/en-GB/' target='_new'>Windows Live Messenger</a></body>
