[MEncoder-users] weird VP7 errors, some fixed

[Jakob Wierzba]

Hi,
maybe someone is having the same issues...

I installed win32-essentials with Mplayer from Ubuntu
(SVN-r29237-4.4.1), encoding worked well with

mencoder c.dv -of avi -ovc vfw -xvfwopts codec=/usr/local/lib/win32/vp7vfw.dll -ffourcc VP70 -nosound -o c.vp7.avi

(mencoder complained when the DLLs where in the default folder; I had
vfw2menc compiled with winegcc, but the options dialogue for the vp7 DLL
wouldn't work (page fault), so I'm stuck with default settings)

BUT playback didn't work, apparently the Fourcc was set to "rceL", as
mencoder ignored the -ffourcc override.
I couldn't find an option to force mplayer to ignore the Fourcc
specified in the file, -vfm wouldn't help.

So i did

sed 's/rceL/VP70/g' c.vp7.avi > c.vp7-correctfourcc.avi

and it worked!

BUT STILL when I try to reencode that file, mencoder keeps dropping
every 10th frame after the 22nd.

Am I missing something or is it one of the quirks of the "binary
codecs"?


Cheers,
Jakob
