Re: N800 video playback encoding & settings
 

OK i've gotten 770-encode and Media Converter to work on some files but not on others...

here is the example output of mencoder if started directly with 770-encode produced command line:

if I remove the "-vf-add scale=352:176" then mecoder goes on an ddoes his thing (but scale is bad :( )

Any ideas ? Thanks a bunch.

P.S. I'll try an find a small video that produces the same problem for posting here.

Re: N800 video playback encoding & settings
 

Here is an example of a fiel that won't be encoded

here is the mencoder command generated by

removing the "-vf-add scale=352:176" makes mencoder accept to encode (but scaling is no good...)

Any ideas ? thanks a bunch.

Re: N800 video playback encoding & settings
 

Looks like you are using a wrong build of mencoder, it tries to use 3DNOW instructions in scaler, but your CPU does not support them.

Re: N800 video playback encoding & settings
 

Thanks alot, Never would have thought of that one... Don't no how that 3Dnow got selected in the first place. Works great now.

:)
