[MPlayer-users] Mencoder not decoding divx?

[Ralph Slooten]

Hi there all,

I am confused as to this encoding problem I have. I have just installed
Mandrake 8.2, and threw away the gcc-0.96 (which is still included as
default!!) and upgraded to gcc3.0-3.0.4-2 (also included).

I had mplayer and mencoder working like a charm with 8.1, but since I
installed 8.2, either something has changed here, or in mplayer/mencoder.
When encoding, mencoder works like a charm with encoding a DVD to DivX
using libavcodec and xvid, however when I try re-encode a film ripped in
DivX (3 or 4, it does not matter) format, it bombs out.

I try encode with:

mencoder Star_Wars_V.avi -o Test.avi -ovc lavc -lavcopts \
vcodec=mpeg4:vbitrate=650 -oac mp3lame -lameopts br=96:cbr -v

and it gives the error of:

mp3lib: using MMX optimized decore!
MPEG 1.0, Layer III, 44100 Hz 112 kbit Joint-Stereo, BPF: 365
Channels: 2, copyright: No, original: Yes, CRC: No, emphasis: 0

videocodec: libavcodec (640x272 fourcc=58564944 [DIVX])
MP3 audio selected
Writing AVI header...
Not supported image format! (Unknown)
Exiting...


I _can_ however play this file with mplayer perfectly!



Then to try a similar test I do a

mencoder -dvd 1 -chapter 1-1 -o Matrix.avi -ovc lavc -lavcopts \
vcodec=mpeg4:vbitrate=650 -oac mp3lame -lameopts br=96:c br -v


... and this works great.

I have exactly the same results with xvid... DVD works great, but not
re-encoding a divx file. Re-encoding an mpeg file does work btw.. It seems
to me that mencoder cannot decode DivX, whereas mplayer can.

I am using todays CVS versions of MPlayer, XviD and libavcodec (tried
yesterdays too). I have configured with both encoders, and also both
individually.

Does anyone have any idea of what's going on here?

Any suggestions would be great,

Greetings
Ralph
