[MPlayer-users] Formal Bugreport, was...mencoder issues .60pre2

[Chris Wertman]

I am submitting a bug report with following
information included as per the bug report request
documentation.

This report reffers to my all so vauge problem of
mencoder pl
ayback of DVD encoded input
and things looking like video on acid, it clears about
every 10 secs and starts melting again.
(see 

I tried -nosound as suggested to no change,
I encoded this with the following commands as stated
in DOCS , ALL get the same result 

    mencoder -dvd 2 -ovc divx4 -oac mp3lame -divx4opts
br=1100 -o test.avi -pass 1
    mencoder -dvd 2 -ovc divx4 -oac mp3lame -divx4opts
br=1100 -o test.avi -pass 2

    mencoder -dvd 2 -o test.avi
    mencoder -dvd 2 -x 640 -y 480 -sws 2 -o test.avi

As I said, ALL output avi's suffer the same issues.

I had to upload a 4 meg slice, to see what artifacting
I speak of , the sky is especially odd for the 20cfx
light sequence.

and (no matter what encode line used above)I get all
the same result on playback, all other files play
fine, ones I had, ones I downloaded etc. EVERYTHING
but the one I encoded, no matter what command I use to
encode it.

I uploaded a test (My output from mencoder, and the
command to run it in the incoming FTP directory

CDWACIDtest.avi
ftp://ftp.mplayerhq.com/MPlayer/incoming/CDWACIDtest.avi

And the full output of 

mencoder -v -dvd 2 -o test.avi
(I figured less options less issues to check and since
all encodes appear same)
CDWACIDtest.log

The DVD I was trying to encode was ID4.....

ALSO , the -cache option seems to help for standard
DVD playback, I didnt see it in the docs and missed it
in the man page, Thanks, 
BUT what is the optimal setting (or average setting)
for this in kb ?



Much thanks, 

Chris Wertman

I also have another question in the docs it states you
have to download and install source tree for
libavcodec seperatly, but it appears in the tree, is
this just an out of date DOCS issue or am ( I tied
with the libavcoded encode as well, same damm thing am
I missing something in regards to libavcodec , hmm if
I take some acid will all this look ok , seems to be
an expensive fix...?
