[MEncoder-users] [flv @ 0x89b8c60]dimensions not set Floating point exception

[Lukas Österreicher]

Hi.

I'm trying to convert to flv, however I get the following error:

[flv @ 0x89b8c60]dimensions not set
Floating point exception

This is the command I used:
mencoder sourcevideo.mkv -of lavf -lavdopts fast:threads=4 -oac faac
-faacopts br=96 -channels 2 -srate 44100 -ovc lavc -lavcopts
vcodec=flv:vbitrate=500 -vf scale=800:448 -o destvideo.flv

I don't know what i'm doing wrong - in fact I am not even sure I am
doing something wrong.
Thre is a similar command exampl mentined here:

that is working according to the auther, but the same is not working
for me (i only changed input and output filenames).

I checked out the latest version using git and compiled it.

Can you help?

Also, Is ther a way to encode to .mp4 directly using x264 and aac
codecs (without other
programs, since i want to stream the output over the internet
eventually instead of storing on disk)?

Thanx in advance,
Lukas

Btw, when using the x264 codec I had to use a version from November
2011 so that encoding works properly and does not give me this error:
mencoder: encoder/slicetype.c:1632: x264_rc_analyse_slice: Assertion `cost >= 0' failed.
