[MPlayer-users] bug report: mencoder fails to make playable .avi from \*.png

[Dean S. Messing]

Using the mencoder commandline:

  mencoder \*.png -mf on:w=325:h=407:type=png -ovc rawrgb -o output.avi

I generate an .avi from a sequence of 120 325x407 .png images.

When I then try to play it with mplayer, using the commandline:

  mplayer -vo xv -vc rawbgr24 output.avi loop 0

I get a black playback window and the output log shown below
which ends with an endless stream of 

    Frame too small! (396825<397232) Wrong format?
    Frame too small! (396825<397232) Wrong format?
    Frame too small! (396825<397232) Wrong format?

The .avi won't play on Windows Media Player either.

Note the correct size of a frame is 325*407*3 = 396825.

Note also that 397232 - 396825 = 407 so mplayer thinks that
the width of the image should be one greater (326) than it is.
I don't know if this is an mencoder or an mplayer bug, but
it sure looks like a bone fide bug to me.

On  the other hand, if I encode the \*.png without any dimensions given
then I _do_ get a playable .avi using both mplayer and Windows Media Player,
but the sequence is spatially truncated to CIF size (352x288) which
is not correct.  (The extra width comes out black.)

I will be happy to place the \*.png sequence on the mplayer site
so you can re-produce the bug (or not :-) if you will tell me where
to upload the sequence.

A previous message:

   http://mplayerhq.hu/pipermail/mplayer-users/2003-January/028589.html

contains the output of Mencoder for the above commandline.

And my system specs are following the mplayer output log below:
