Core dump when transcoding video with samplerate=44100

Postby Lord.Quackstar » 15 Jul 2012 03:11

When testing VLC as a transcoder I stumbled upon what I think is a bug. When transcoding with samplerate=44100, VLC core dumps. When transcoding with samplerate=48000, the audio chain is broken and there is no audio.

Some quick info:
Test file (10 MB): http://dl.dropbox.com/u/62637452/example.mkv
OS: Fedora 17, fully updated
VLC: 2.0.2 Twoflower (revision 2.0.1-453-g40d9fef)
(vlc sourced from rpmfusion repo)

Playing this file normally in VLC gives audio. However when transcoding with this I get "Floating point exception (core dumped)"

Code: Select all

vlc -vvv -I dummy "example.mkv" --sub-language=jpn,eng --sout '#transcode{venc=ffmpeg,vcodec=mp1v,acodec=mpga,vb=4096,ab=128,channels=2,samplerate=44100,soverlay}:std{access=file,mux=mpeg1,dst="out.mpeg"}' vlc://quit
Full verbose output

First, is there anything I'm doing wrong? Is there a temporary alternative?

If there isn't, then is there any more information I can provide to help the devs solve this issue?
