Hi,
I tried to register on the mencoder-users mailing-list but to no avail. So, I think this is probably the best place to talk about my issue:
I downloaded this screencast:
http://railscasts.com/episodes/199-mobile-devices
(55megs, Quicktime RLE)
I tried to encode it with Video4Fuze to watch it on my Sansa Fuze (Video4Fuze is just a handy GUI on top of mencoder and avidemux)
This failed and gave me a pretty small file, lasting only a few seconds, when the screencast lasts 5 minutes.
In addition, while the audio is ok, the video is way way too fast.
When I try to launch mencoder using the same parameters used by video4fuze, I get this from mencoder:
mencoder.exe -ss 00:00:00 -ffourcc DX50 -ofps 20 -vf

Too many audio packets in the buffer: (4096 in 1121863 bytes).
Maybe you are playing a non-interleaved stream/file or the codec failed?

I tried with the -ni option, just in case, but with no success.
