Hi,
Am I understanding get_iplayer correctly?
I've been successfully downloading episodes 1-7 of their adaption of
‘His Dark Materials’. Come the last episode, it's only available in low
resolution and audiodescribed to boot meaning that voice-over from Big
Brother is moonlighting with ‘Lyra is now entering the charnal house’.
--info for the PID m000csdk shows
web: https://www.bbc.co.uk/programmes/m000csdk
Viewing that in Firefox shows audiodescribed and doesn't seem to let me
turn it off.
There's two versions.
version: technical
versions: audiodescribed,technical
modes: audiodescribed: dvfxsd1,dvfxsd2,dvfxsd3,dvflow1,dvflow2,dvflow3
modesizes: audiodescribed: dvfxsd1=690MB,dvfxsd2=690MB,dvfxsd3=690MB,
dvflow1=188MB,dvflow2=188MB,dvflow3=188MB [estimated sizes
only]
verpids: audiodescribed: p07ym92s
modes: technical: dvfhd1,dvfhd2,dvfhd3,dvfsd1,dvfsd2,dvfsd3,dvfxsd1,
dvfxsd2,dvfxsd3,dvfhigh1,dvfhigh2,dvfhigh3,dvfxhigh1,dvfxhigh2,
dvfxhigh3,dvflow1,dvflow2,dvflow3,subtitles1,subtitles2
modesizes: technical:
dvfhd1=2179MB,dvfhd2=2179MB,dvfhd3=2179MB,dvfsd1=1209MB,
dvfsd2=1209MB,dvfsd3=1209MB,dvfxsd1=690MB,dvfxsd2=690MB,
dvfxsd3=690MB,dvfhigh1=675MB,dvfhigh2=675MB,dvfhigh3=675MB,
dvfxhigh1=356MB,dvfxhigh2=356MB,dvfxhigh3=356MB,dvflow1=188MB,
dvflow2=188MB,dvflow3=188MB [estimated sizes only]
verpids: technical: m000d182
Despite that, it seems no technical streams work. --streaminfo's first
stream is

Specifying ‘--modes dvfhd1,dvfhd2,dvfhd3’ picks the technical version.

It seems to me the BBC encoding of this final episode has gone wrong,
leaving just the audiodescribed version available. That's fair enough,
but what's surprising is that they haven't noticed this themselves from
their monitoring and alerts. Or am I misinterpreting get_iplayer's
output and a decent resolution, Big-Brother-less audio, download is
possible?
