 I have 4 files of a Ikegami GFPack camera and want to concatenate them to
 one single file. Problem is, as soon as FFmpeg reaches the second file it
 segfaults.
 Files can be found here:
 https://cloud.obstkiste.org/index.php/s/I2OUb2s4n22cvT7

 I also tried to encode the single files first and transcode them
 afterwards, but FFmpeg refuses to transcode every file except for the
 first one.

 thanks,
 steved
