Running oggenc with the -b option (to specify bitrate) and forgetting the bitrate results in a bogus error message. Rather than something like: ERROR: No bitrate specified. Use -h for help. it responds with an incorrect "No input files specified". For example: [kaboom@verdande wav]$ oggenc -b 10_exit.wav OggEnc v1.0 (libvorbis 1.0) (c) 2000-2002 Michael Smith <msmith.au> ERROR: No input files specified. Use -h for help. [kaboom@verdande wav]$ Compare that with the correct command line, below: [kaboom@verdande wav]$ oggenc -b 320 10_exit.wav Opening with wav module: WAV file reader Encoding "10_exit.wav" to "10_exit.ogg" at approximate bitrate 320 kbps (VBR encoding enabled) [100.0%] [ 0m00s remaining] \ <snip> it's the bitrate that's missing, not the input file....
A warning is now output that the specified bitrate is not recognized, e.g.: walters@nexus> oggenc -b /usr/share/sounds/question.wav /src/work/rpms/vorbis-tools Warning: nominal bitrate "/usr/share/sounds/question.wav" not recognised OggEnc v1.0.1 (libvorbis 1.0.1) (c) 2000-2003 Michael Smith <msmith> ERROR: No input files specified. Use -h for help.
