Comment (by cehoyos):

 Replying to [comment:3 elisnow]:
 > ffmpeg outputs the `overread 8` error and outputs a mostly green video.


 > If you save the data uri jpegs to files and modify the concat script to
 use those jpeg files, it works properly.

 How can I reproduce this?
 When I tried to, I saw the same green images and given the many repeated
 characters in the base64 encoding that you provided, this did not surprise

 > It is only with data uris that ffmpeg is misbehaving.

 While this is absolutely possible (and would indicate a bug) I was unable
 to reproduce this.
