Hi All.

Ubuntu 9.10, TMS 5.1.13 (and 12 and 11). Trying to on the fly transcode FLAC to MP3 to my Sony Bravia. Pounded away at this for 2 nights now. All the FLAC files show up in the Sony menu as MP3's. When i pick on them, I get "cannot play file." and occasionally reboots my TV.

I've created my own flac-mp3.desc.... it is....

# transcode audio (flac to wav)
#(c) 2010 by PacketVideo
#exec: ffmpeg -i $infile $outfile
exec: flac2mp3 $infile $outfile
# capabilities
from=audio/x-flac
to=audio/mpeg

and my own flac2mp3..... it is....

#!/bin/bash
#/usr/bin/flac --silent --decode "$1" | lame -b 192 "$2"
/usr/bin/ffmpeg -i "$1" "$2"

flac2mp3 works from the command prompt.


As you can see with the comments out I've tried a couple things. Here is the the portion of the log file when I try and play a FLAC file........

I can see that it is calling my flac2mp3 script, but it's doesn't look like it's passing $infile and $outfile to the script, so it just stops.
I've added .location files for ffmpeg, lame, mplayer, and flac (I've tried many many things to get this to work), and have tried both symlinks and copying the binaries inthe cgi-bin directory.

So, what am I missing, and why isn't it working?? Thanks

Have you tried this?

(if your TV does not do PCM/WAV, then change the script). In particular, the synchronous bit. That makes the difference between it working and not working on the PS3.

I did try that with mixed results. It looked like I could stream WAV to Windows Media Player from FLAC, but the TV doesn't do WAV. The decoded WAV file showed up in the cache. The TV does do LPCM. I tried the script further down that used FFMPEG to create LPCM from FLAC, but no joy there. Once more the Files are shown in the tree, but nothing get transcoded.

An update.

Another 3 hours scrapping with this. Found an error in my flac-desc.mp3, and extra space was causing trouble. FFMPEG still a no go. Made a new FLAC2MP3 script so I could follow what was happening......

#!/bin/sh
# Converts anything FLAC to mp3
# Usage: flac2mp3 infile outfile

# Command line arguments
INFILE="$1"
UTFILE="$2"

# Lame options
QUALITY=cd
MRE_LAME_ARGS=""
touch /tmp/0
pipe=/tmp/mp3pipe.$$
#rm -f /tmp/out.wav

# Do the conversion
touch /tmp/1
flac --silent --decode "$INFILE" -o /tmp/out.wav
lame -b 196 /tmp/out.wav "$UTFILE"
touch /tmp/2
# Clean up
#rm -f /tmp/out.wav


added the touch statement to see where the script is hanging, and it's isn't!! I have files 1,2 and 3 in my tmp directory as well as out.wav. I also have a 0byte MP3 in the cache that won't play. Once more, the script works fine from the command line. So my guess is that lame is crashing.

I HAVE IT FIGURED OUT!!!!!!

you have to /dev/null all messages or use the silent flags, else it just crashes.
