Transcoding FLAC -> Vorbis results in invalid file

[auxym]

I am using VLC 2.0.1 (on windows) and trying to transcode FLAC files to Vorbis. The intention is HTTP streaming, but the result is the same no matter the destination, even a file output. Here is my sout, for example a file output:

Code: Select all

:sout=#transcode{vcodec=none,acodec=vorb,ab=128,channels=2,samplerate=44100}:file{dst=E:\\temp\\graze.ogg} :sout-keep

In my audio encoder settings, for Vorbis, the quality is set to 4. The resulting output file is about 30 kb and appears to contain only headers, no audio data. I get a similar result using mp3 output.

However, if the input file is WAV (instead of flac), then everything appears to work as expected. So this appears to be an issue with the flac decoder? Here is my messages log on debug verbosity, there does not appear to be any error logged:

Hi
Maybet it's this bug ---> https://trac.videolan.org/vlc/ticket/6400

[auxym]

Thanks for the answer, it does appear to be this bug. The trac page specifies the linux platform, but I'm also getting it on windows.

Also, I tried the latest git release of 2.1.0 (20120611) and am getting the same bug.

Hoping to see it fixed in the official release of 2.1.0, I guess.
