oggenc >FILE creates a wrong file
Let me reproduce the bugreport I sent to the Debian bug-tracking system:
Subject: oggenc: --output=FILE and >FILE have different results
Package: vorbis-tools
Version: 1.0rc3-1
Severity: important
oggenc seems to create different files depending on the style of the
commandline, whether it is
$ cat test.raw | oggenc --raw - --output=test-inputpipe.ogg
or
$ cat test.raw | oggenc --raw - > test-pipe.ogg
The big trouble is that the latter method (> FILE) produces a file
that ogg123 can read without any visible error/warning, but ogginfo
says that the integrity test fails, and vorbiscomment doesn't even
recognize the file as a Ogg file.
An example should make this clearer:
================================================================
*** First, we create the files.
$ oggenc --raw test.raw --output=test.ogg
Encoding "test.raw" to
"test.ogg" at quality 3,00
Encoding with VBR
Encoding [ 1m39s so far] -
Done encoding file "test.ogg"

Elapsed time: 1m 40,2s

$ cat test.raw | oggenc --raw - > test-pipe.ogg

standard output at quality 3,00

$ cat test.raw | oggenc --raw - --output=test-inputpipe.ogg

*** Now, we try these files:
$ ogginfo test.ogg

*** No problem for test.ogg.

*** No problem. Now let's try vorbiscomment:
$ vorbiscomment test.ogg
$ vorbiscomment test-pipe.ogg
Failed to open file as vorbis: Input is not an Ogg bitstream.
