Thank you for taking care of this.  But I think you patched
only -analyzeduration, but not -probesize:

$ ffprobe -analyzeduration 4G -probesize 4G dvdstream-1.mpg

dvdstream-1.mpg: Result too large

When I specify -analyzeduration 4G -probesize 2147M, there
is no error message, but the subtitle stream that begins
after the 2 GB boundary is not found.

Best regards
   Oliver
