467	Encoding an image only movie fails when used with the movie overlay filter	jogga		"I'm trying to overlay a QuickTime? movie that consists of PNG images on top of another movie. I have noticed that FFMPEG doesn't seem to handle such an image-only movie correctly when used in combination with the movie overlay filter.

'''This is my command line:'''

ffmpeg -y -i /Users/jogga/Desktop/skiing.mov -acodec copy -s 640x360 -vcodec libx264 -vpre slow -vpre ipod640 -crf 22 -threads 0 -vf ""movie=/Users/jogga/Desktop/skiing_subtitles.mov:f=mov, pad=640:360:0:286:0x00000000[subtitles];[in][subtitles] overlay=0:0:1[out]"" /Users/jogga/Desktop/skiing_subtitled.m4v

'''And this is the uncut output of the operation:'''

The first sample in the overlay movie ""skiing_subtitles.mov"" starts at exactly 4 seconds. When encoded using the command line above FFMPEG skips the first 4 seconds of empty samples and the first sample is shown on frame 1 instead of frame 100 in the resulting output movie.

I have attached all the sample files and a screenshot.
