Trying to transcode a mxf prores video file (spanned) to mov x264 — at Initial Version

Description

Summary of the bug:

With the Canon EOS C300, it spans clips. In our case, these clips are being ingested into Avid Media Composer and the video is encoded to ProRes?. Generally we transcode each part of the spanned clip and then concatenate the clips together to form one clip. However, with ProRes? in particular, the first clip of the spanned clips will transcode but the remaining clips will not.
I've tried explicitly specifying the format, the video codec, ffmbc, but I keep encountering: Output file #0 does not contain any stream

How to reproduce:
/home/pw/bin/ffmpeg -c:v:0 prores -r 23.98 -i /mnt/loadingdock_tc1/.A00001V01.D435447D_580FF66A060a2b340101010101010f0013000000580ff66a8f4e0162060e2b347f7f2a80.mxf -b:v 800k -maxrate 800k -s 320x240 -vcodec copy -y -threads 0 -report '/tmp/media/BZ0_MEDIA/LOCAL/BZ01020A01/2BZ01020A01-1.mov'
