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.
