Transcoding MMS (windows audio) to mp3 sped way up!

Posted: 06 Oct 2008 23:05

Howdy folks... Since upgrading from the 0.8.6 branch to 0.9.2 (and 0.9.3 still) I've found that when several mms streams are transcoded to mp3, the audio is sped up to chipmunk speeds! It doesn't affect all mms streams, but several. I've confirmed it on windows xp, mac os x 10.4 and 10.5 (ppc and intel respectively).
Here's the command I'm running (this stream: mms://200.43.193.143/radio10 exhibits the problem). I've tried clearing preferences but the problem persists!


/Applications/VLCnew.app/Contents/MacOS/VLC -vvv -I dummy "mms://200.43.193.143/radio10" '--sout=#transcode{acodec=mp3,channels=2,ab=64,samplerate=44100}:standard{access=file,mux=raw,dst=out.mp3}"'

(Extended output pasted below)

Any help would be appreciated!
Steve

Re: Transcoding MMS (windows audio) to mp3 sped way up!

Posted: 28 May 2009 01:22

I realize my response is several months late, but here goes.

I've had some issues transcoding WMA streams to Shoutcast. Certain ones would give this skipping sound (sorta like when you skip ahead on a CD). To me it sounds like there's a buffer underrun condition there. My command line is this:

vlc -vvv --play-and-exit -I dummy [INPUT STREAM] --sout '#transcode{acodec=mp3, ab=128, channels=2, samplerate=48000, aenc=ffmpeg}:std{access=shout{mp3=1, bitrate=128, samplerate=48000, channels=2}, mux=ogg, dst=[USER]:[PASSWORD]@[IP]:[PORT]//}'

Simply changing the 'bad' WMA stream to a 'good' WMA stream clears up the problem. As for the chipmunk sound, if your bitrate is off then it can raise or lower the pitch of the music (the audio sounds like it's dragging or sped up.)

In my experience, try a few different WMA streams. I have more trouble transcoding an incoming MMS/WMA stream than an incoming Shoutcast/MP3 or RTSP/AAC+.
