[FFmpeg-user] Invalid pixel aspect ratio 65536/65536, limit is 255/255

[mouk naj]

hi there,

i am getting an "Invalid pixel aspect ratio 65536/65536, limit is 255/255"
error message when using ffmpeg 0.8

i am able to work around this issue if i simply remove CODEC_ID_MPEG4 check
from libavcodec/mpegvideo_enc.c:MPV_encode_init() where this error is
generated, but that obviously isn't right way to solve it.  when we used 0.6
version of ffmpeg, this problem didn't exist.  here is the command line:

/usr/local/bin/ffmpeg -y -timelimit 60 -i
/d4/26/10/1/9/19058ef0b381265b7bf7ff9eefe8c402.3gp -r 30 -ab 12288 -vcodec
mpeg4 -acodec libfaac  -b 2097152  -sample_fmt s16
/d4/26/10/1/9/iphone.19058ef0b381265b7bf7ff9eefe8c402.mp4

here is full output of the command:

(i tried ftp uploading sample video to upload.ffmpeg.org as instructed in
the "reporting bug reports" section, but server seems to be down)
