I'm paying a bit more attention this time.

The cmp_modes() function scores a mode and compares two modes by their
score.  Unfortunately, there's no `score_mode()' function so that the
list of modes that's verbosely output can be augmented by their score.
However, I added

main::logger "NICK: ranks: $x $rank_x v. $y $rank_y\n";

just before the last line, the `<=>', of cmp_modes and then prefixed the
`INFO' lines that were already output for PID `b09hlzbb'.

From this list, and the base amounts that comprise a score in that
function, you might be able to see why it thinks it's giving you the
`best';  I expect x×y resolution isn't the central criteria.

It does. Look at all those "403 No Protocol" errors. If you can't download the 
stream information, GiP won't be able to access them. You got the best 25fps 
stream available in both cases. As to why you get those errors, I haven't a 
clue. The URLs clearly have protocols included, and you would see a different 
error if they didn't, so the errors must refer to problems on the BBC side or 
somewhere in between. Even in your example, some errors aren't repeated, so 
might be difficult to diagnose.

Yes, if I use --fps50 with --tvmode=best then I get the 1280x720 50fps
stream. However, I have yet to view a program where I thought that 50fps
gave an advantage over 25fps, so from my point of view using it means
having to download files of twice the size for no visible advantage.

I too am unclear on how the `better', `best', etc., map to modes.  You
might want to experiment with the --fps50 option as that seems to
influence the definition of `best' and friends.

Yes, I thought that was out of date when skimming it a couple of weeks
ago.  I think get_iplayer changed partly because 25 fps is the `best'
most folks want for throwaway TV fodder.

Modes and best quality

2017-12-13 Thread Nick Payne 
I have noticed, on numerous pids, that if I download them using

--tvmode=best

then the highest quality 25fps stream that is found is dvfxhigh (704x396
25fps).

However, if I explicitly use --tvmode=hlshd, then I get the 1280x720
25fps stream.

As an example, here's the console output from downloads of pid b09hlzbb
(Expedition Volcano episode 1), first using --tvmode=best and then using
--tvmode-hlshd.

This behaviour does not accord with the documentation at
https://github.com/get-iplayer/get_iplayer/wiki/modes, which gives as an
explicit example using --tvmode=best to get 1280x720 @25fps:
