Leo Butler a483779bc1 Compensate for ffprobe deficiency in probing h265-encoded files
The current version of ffprobe,

ffprobe version 4.2.4-1ubuntu0.1 Copyright (c) 2007-2020 the FFmpeg developers

prints a value of 0 for each frame number in an h265-encoded
mpegts. So, we need to count for ourselves.

----

Experiments with h265-encoded videos shows that there is great
compression (~30-40% better than h264), but:

-the mythling player on android can't play them;
-the 8-yr old asus frontend can play cartoons fine, but not
 "real-life" video
-transcoding is about 1/3 the speed with libx265 vs. libx264

I will revisit the issue when one of the first two points makes it
possible, but until one of them needs to be replaced, I will stick
with h264.
