Forum user Harry_V uploaded a jpeg2000 stream that cannot be decoded with
FFmpeg since fcd19d6c8db514b017662166d014ac8560fbe8f5 - related to ticket
#2897. I will attach two jpeg2000 frames from the original stream: Both
decode fine with separate FFmpeg command lines, decoding the second frame
fails if both frames are decoded with the same command.
