[MPlayer-users] Problem encoding mp4 file

[zikzak at tele2.fr]

Hi,

Following the advice of Kichigai Mentat, I used the CVS version of
mplayer to create a MP4 file (Quicktime + AAC).

Here is the commande line I used :
mencoder -oac faac -of lavf -o r5_mencoder.mp4 r5.mpeg -ovc lavc
-lavcopts vqscale=5

The output has no video (audio is ok).

During the encoding process I can see these lines :

success: format: 0  data: 0x0 - 0x1bc2004
MPEG-PS file format detected.
VIDEO:  MPEG1  320x240  (aspect 1)  59.940 fps    0.0 kbps ( 0.0
kbyte/s) [V] filefmt:2  fourcc:0x10000001  size:320x240  fps:59.94

VIDEO CODEC ID: 12

This one seems strange :
Expand: -1 x -1, -1 ; -1, osd: 1, aspect: 0.000000, round: 1

and in the output file I have the following line :
QuickTime/MOV file format detected.
--------------
MOV track #0: 3146 chunks, 3146 samples
MOV: Found MPEG4 movie Elementary Stream Descriptor atom (35)!
Image size: 0 x 0 (24 bpp)
Display size: 0 x 0
Fourcc: mp4v  Codec: ''

The image size is 0 x 0.

Can you explain it please ?
