The first comment to make is that this is not the problem with HLS which has
been plaguing us for the last month or so and now seems to be fixed. You
are downloading HVF, hvfhd1, and not HLS.
There are two types of error. dinky criticised users reporting errors (I
think he meant me!) for not distinguishing them. I was referring to errors
because I thought everyone knew we were talking about HLS Segment not found
errors. The Segment not found error as it was called in v2.95 has had its
description changed in v2.96 to something like Unable to find segment on
server. What it means is that something has gone wrong in the segmenting
process by Akamai, and the segment does not exist on the server. There is
no point in retrying because the segment is not there. It was this type of
error we were experiencing more and more frequently with HLS.
You have the other type of error, Failed to download segment. This is only
the second instance of this type of error I have ever seen. The other one
also occurred with HVF. I understand it has a wider range of possible
causes, so get_iplayer retries. dinky says it retries twice. I thought I
saw more retries than that but I haven't kept the screen display so I can't
argue. In my case the retries just made another unsuccessful attempt to
download the failed segment. In your case a completely different error has
occurred on the retry.
I had understood that in v2.96 an error of this type was to cause the next
mode in the list to be tried. That has not happened.
In my case I tried to reproduce the error the following day, but it had gone
away. You could try again in a few hours, but I see you have a very slow
I have not used v2.96 yet so I can't comment from my own experience. I was
surprise at the list of modes listed to be tried. I had understood the
default in v2.96 was to be HVFSD. In your case it has defaulted to hvfhd1.
I had also understood in v2.96 that HLS was to be removed from being a
default, yet hlshd1 appears in the third position of modes to be tried.
Another curiosity is that it has attempted to download the editorial
version. You'll have to ask someone else the significance of that.
