 Summary of the bug:
 I am trying to turn a stream of jpeg's into a video but the concat demuxer
 is erroring with the data uris. An output video is produced but it only
 has the top part of the images included with the rest of each frame being

 (I'm actually programatically generating the concat script and feeding it
 into ffmpeg's stdin, but for the sake of this repro case attached is a
 static concat script)

 How to reproduce:
 ffmpeg -report -f concat -safe 0 -protocol_whitelist file,data -i concat
 -vf fps=30 -y out.mp4

 The main error looks something like:
 [mjpeg @ 00000215a6bbd9a0] overread 8

 Attached is the output of the `-report` option.

 As is obvious from the report log I am running on Windows (version 10).
