-------------------------------------+-------------------------------------
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
