Hi

Currently, indytube uses mencoder for the conversion to FLV, which is
referenced by the HTML .inc file , ie by the inclusing of Flowplayer to
playback the FLV in the browser.

ffmpeg2theora is used to make OGGs , but 'out of the box' they are not
used.

We have had nutted out this mencoder options line,

MENCODER_OPTIONS=-really-quiet -of lavf -oac mp3lame -lameopts abr:br=64
-ovc lavc -lavcopts
vcodec=flv:keyint=25:vbitrate=260:mbd=2:mv0:trell:v4mv:cbp:last_pred=3
-vf harddup,expand=:::::4/3,scale=320:240  -srate 22050 -ofps 25 -mc
0/10

which seems to give better sync results, and better conversion of WMVs
to FLV, which were totally problematic.

As to why you dont get any output from MEncoder doing it on the cmd line
- you need to get rid of any "-quiet" / "-really-quiet" options.

let us know what happens.
