avcodec not decoding mpeg4 480x360 1fps video

Hi, I'm attempting to play back a video that has been encoded into mpeg4 480x360 at 1 FPS. The encoding command is below.

The output video works okay on in win7 quicktime, win7 Windows media player, ubuntu media player, but not the VLC current version 2.0.5 on either the windows or ubuntu platforms.

VLC is playing other types of movies fine.

The error reported by VLC is: "avcodec error: more than 5 seconds of late video"

FFMPEG Encoding parameters: (early 2013 build version of ffmpeg)

ffmpeg -y -i A62770.wav -i A62770.m2v -s 480x360 -r 1 -qscale 5 -vcodec mpeg4 -threads 0 -acodec libfaac -ac 1 -ar 22050 -ab 64k 68.fps1.mpeg4_qscale5.480.360.A627700001.mp4

Example video is attached.

Any advice on changing encoding parameters to get this issue resolved, and fixing the issue would be appreciated.

Thanks, Graham
