Summary of the bug: Videos are converting to mp4 files. There are 4
presets with different video resolutions.
Generally it's working.
But some videos get's distorted in few resolutions.
For example: http://gravity-magazine.de/de/videos/dirt-jumpstreet-
produzierte-videos-crashes-kurze-clips/3763
Watching this movie in 240p, 480p is still okay.
But when you switch to 720p or 1080p it's totally distorted.
I think, it only happens when the source video has a smaller resolution
then the preset.
Video codec: H.264 / AVC / MPEG-4AVC / MPEG-4 part 10 (encoders: libx264
libx264rgb)
Aspect mode: Preserve aspect ratio (default)
Upscale: checked
How to reproduce:

Patches should be submitted to the ffmpeg-devel mailing list and not this
