conversion to mp4 of a video with audio never finishes

[Alessandro Nilsen]

Hello, this happens every time I try to convert a video with audio to mp4.

I have a video named myVideo.avi and I wanna convert it to mp4 with the sdb preset, using LC-AAC stereo with 110kbps.
The process stuck in:

-> Track 1: Encoding audio with 'faac' to LC-AAC, please wait...
-> Track 1: This can take a while...

Seeing the code I find something:

The command "mkfifo "$TEMPDIR/audio.wav" creates a file audio.wav that the mplayer can't write, the file in the folder ~/.h264enc/job14705/audio.wav remains always with 0b of size.

I think the part that is getting stuck is this:

mkfifo "$TEMPDIR/audio.wav"
FIFO="test -p \"$TEMPDIR/audio.wav\" || mkfifo \"$TEMPDIR/audio.wav\""
MPL="$MPLAYER \"$OUTPUT\" $MPLAYEROPTS -really-quiet -vc null -vo null -nocache ${channels[1]} -ao pcm:fast:file=\"$TEMPDIR/audio.wav\""
NERO="$NEROAACENC -ignorelength ${neroaacbr[1]} -if \"$TEMPDIR/audio.wav\" -of \"$TEMPDIR/audio.aac\" &"
AACPLUS="$AACPLUSENC \"$TEMPDIR/audio.wav\" \"$TEMPDIR/audio.aac\" ${aacplusbr[1]} &"
OGG="$OGGENC ${vorbq[1]} \"$TEMPDIR/audio.wav\" -o \"$TEMPDIR/audio.ogg\" &"
FLACENC="$FLAC ${flacq[1]} \"$TEMPDIR/audio.wav\" -o \"$TEMPDIR/audio.flac\" &"
FAACENC="$FAAC -w --mpeg-vers 4 ${br[1]} ${tns[1]} $faacparams \"$TEMPDIR/audio.wav\" -o \"$TEMPDIR/audio.aac\" &"

Thanks!
