 (In [26173]) Fixes #8873. The seek to end optimization was using an int
 rather than a guaranteed 64-bit or larger type to check if the seek had
 succeeded, so it failed for all files larger than 2^31 when int was a 32
 bit type, files larger than 2^15 when int was a 16 bit type, etc. Also
 since the seeks done when doing an mpeg-ts seek don't match the pattern
 that this optimization is for, I've disabled this optimization when the
 offset from the end of the file is not exactly 250,000 bytes. So this
 optimization will only be triggered where we know it will do some good..
