[MEncoder-users] TiVo MPEG-TY file encoding problem...

[Burrows, Ashley]

I've transcoded many files from my tivo (a UK Series 1 tivo) into DivX.
I use the following command line:

 

Mencoder <tivofile.ty> -o <divxfile.avi> -mc 0 -oac lavc -ovc lavc
-lavcopts vcodec=mpeg4:vhq:acod
ec=mp3:vbitrate=800:keyint=250:vpass=1:turbo -ffourcc DIVX -vop
scale=::::::pal

 

Mostly, this works with no problems at all, but every now and then, it
doesn't work (about 1 file in 10 maybe)... this is the output from the
precompiled version available at
http://armory.nicewarrior.org/projects/cygmp/

And this is the output from a recent cvs version I compiled myself:

Any idea why mencoder/mplayer thinks this is a MPEG-PS file rather than
a MPEG-TY file (which it is).  The same file plays back fine on the TiVo
and in Windows Media Player, using TyShow, so I do not believe it to be
corrupt in any way.

 

Any help or advice much appreciated...

Thanks,

Ash.
