In response to Monty of Xiph

I decide to compile a recent version of FFMPEG that use AoTuV vorbis instead of vanila libvorbis (which haven't fully incorporated Aoyumi's works) and intentionally exclude native vorbis encoder (to prevent accidental encoding).
As you know, it capable of q -1 and -2 thus great for bandwidth-starved situation. BTW I also include WebM's vp8 encoder if anyone want to try the combination but I felt it was very slooow somehow (the vp8 encoding not vorbis).

My interest is however to make FFMPEG as All (including videos) to streaming audio (AoTuV) converter that also transfering tags/metadata thus only lack replaygain calculation in the process. Of course it is not in league with SOX in term of quality but hey it decode more formats biggrin.gif

Here is my build today: ffmpeg r24503 Win32, MT, CPU runtime detect
ffplay to test WebM content, just drag n drop onto to play

plain batch conversion example:
for /r %f in (*.mp3 *.aac *.m4a *.vqf *.mp2 *.ac3 *.wma *.ra) do ffmpeg -i "%f" -acodec libvorbis -aq 0 -map_meta_data 0:0 -y "%~dpnf.ogg" && vorbisgain -q -s -f "%~dpnf.ogg" && del "%f"

for video clips:
for /r %f in (*.avi *.wmv *rm *.asf *.mov *.mpg *mp4) do ffmpeg -i "%f" -vn -acodec libvorbis -aq 0 -map_meta_data 0:0 -y "%~dpnf.ogg" && vorbisgain -q -s -f "%~dpnf.ogg"

Please test biggrin.gif
