I am trying to use mencoder in my little GUI to create VP8 encoded
filtes. From what I see that support is not natively working (yet?).
Anyhow, there are patches but I don't seem to be able to apply come of
them. Decoder support appears to be there.
So I am trying to pipe the output into ivfenc via something like this
(this is Nic's modified version accepting pipes).
mencoder -dvd-device "D:\ElephantsDream\VIDEO_TS" dvd://1 -ovc raw
-noskip -vc mpeg12 -vf scale,format=i420 -forcedsubsonly -nosound -mc 0
-lavdopts threads=8 -really-quiet -fps 25 -aspect 1.7775:1 -of rawvideo
-o - \
| ivfenc --passes=1 --pass=1 --target-bitrate=1500 --width=720
--height=576 --timebase=1/25 --i420 - "D:\Encoding Temp\Title_1_1-8.vp8"
Ivfenc complains that the output is not in Y4M format. I have to claim
utter ignorance here but I am told that -of rawvideo does not produce a
y4m skeleton whatever that is.
Do you know how to talk it into this?
