#3815: libcdio only works with -ss 00
----------------------------------+---------------------------------------
Reporter: gerion | Type: defect

----------------------------------+---------------------------------------
Summary of the bug: The (undocumented) libcdio device does not work
directly.
How to reproduce:
{{{
ffmpeg -f libcdio -i /dev/sr0 test.wav
}}}
always end instantly and did not produce any valid file.
A possible workaround is:
{{{
ffmpeg -ss 00 -f libcdio -i /dev/sr0 test.wav
}}}
I use git version.
(I tried on another computer with ffmpeg stable release and it didn't
work, too.)
Here is the output:
$ ffmpeg -f libcdio -i /dev/sr0 test.wav
